# [PATCH] loop.c cleanups
#
# This does the following:
# - remove trailing spaces
# - make loop.h independent by including bio.h, blk.h, spinlock.h
# - replace the lock/unlock functions by module_get/module_put;
# in struct loop this is the change
# - void (*lock)(struct loop_device *);
# - void (*unlock)(struct loop_device *);
# + struct module *owner;
# - replace the integer lo_encrypt_type by the pointer lo_encryption;
# there was a race with loop_unregister_transfer
# - fixed an off-by-one in loop_register_transfer
#
# This is Step 1 of a series of half a dozen or so.
#
# Half of the above is from Jari. Anything that is wrong is mine.

# 03/06/22 ldl@aros.net 1.1348.17.3
# [PATCH] fix nbd driver for 2.5 block layer
#
# This makes NBD work with the new linux 2.5 block layer design.
# Specifically, it fixes memory corruption that results from module
# removal and possible memory corruption from sending or receiving disk
# data from the server.
#
# It essentially rolls together the changes from two of the last patchlets
# that I emailed: the fix for module removal & the fix for incorrect
# struct bio usage. I believe it's wisest to roll these both together
# into this one patch since they both deal with making NBD work better
# with the 2.5 linux block layer design and without either of which, it's
# possible that NBD will corrupt memory.
#
# Other changes I'd like to see introduced (like in the earlier jumbo
# patch) meanwhile are feature enhancements so they can wait. This patch
# also should address all the very helpful concerns that have been raised
# so far. Particularly:
#
# 1. that the very first submitted NBD patch was broken down [Andrew]
# 2. that only 1 spinlock is used for all the NBD request_queue structures
# used [Jens,Al]
# 3. that kmap() is used in case of highmem pages [Jens]
# 4. that the allocation of request_queue is dynamic and seperate from
# other allocated objects [Al]

# - update dvb subsystem core

# this makes the patch rather large.
# - updated the dvr (digital videorecording) facility
# - renamed some structures, like "struct dmxdev_s" to "struct dmxdev"
# - introduced dvb_functions.[ch], where some linux-kernel specific
# functions are encapsulated. by this, the dvb subsystem stays quite
# independent from deeper linux kernel functions.
# - moved dvb_usercopy() to dvb_functions.c -- this is essentially
# video_usercopy() which should be generic_usercopy() instead...
# - Made the dvb-core in dvbdev.c work with devfs again.
# - remove all typedefs from structs

# [PATCH] Include update mode in declaration of RPC information caches.
#
# The sunrpc/cache.c caches which store nfsd export information
# can be updated either "inplace" or by replacing the entry.
#
# replacement is needed when an entry hold a reference to some
# other object, so the reference counts work properly.
#
# "inplace" can be used when no such references are held, and should be
# used when the object could be refered to by another cache (as otherwise
# the other cache would have to be updated whenever this one is).
#
# Previously the type of update (inplace or replace) was specified
# as an argument to the *_lookup operation. This too easily lead to
# inconsistancies.
#
# With this patch, the update mode is specified when the cache is
# declared.

# [PATCH] loop.c - part 2 of N
#
# This does the following:
#
# - IV value is current 512-byte sector relative to start of loop
# container file. This is what all cryptoloop people have done, if I
# am not mistaken. Andi or others - if you can demonstrate the need
# for a more flexible setup an additional ioctl field may be needed. I
# hope we can do without.
#
# - made some things static
#
# - made lo_offset a loff_t
#
# - added lo_sizelimit
#
# If one wanted a (crypto)loop somewhere inside a container file, the
# old code allowed a starting offset, but no size, so that the
# cryptoloop always extended to the end of the container file. This
# field allows one to select an arbitrary interval. Note that this
# changes struct loop_info64.
#
# - improve error handling of loop_init()
#
# - removed the unused typedef transfer_proc_t.
#
# - added a define for LO_CRYPT_CRYPTOAPI

# [PATCH] unexpected IO-APIC update
#
# Recently there has been a rash of Unexpected IO APIC reports on the
# linux-smp mailing list. Most of the most recent ones are due to some
# newer Intel chipsets (865, 875).
#
# The IO APIC Version register doesn't indicate the differences in these
# IO APICs.
#
# I have an patch that addresses these chipsets. It has been tested by a
# few people with good results and has been blessed by Maciej Rozycki.
#
# Other than conditionally decoding IO APIC registers 2 and 3, we could
# alternately ignore them since Linux doesn't use the values for anything
# other than printing them.
#
# This patch ignores IO APIC register 2 if it's the same value as IO APIC
# register 1. It also reads IO APIC register 3 if the IO APIC version is
# >= 0x20, but some chipsets don't support this register, so it is also
# ignored if its value if the same as IO APIC register 1 or 2.
#
# Another possible(?) alternative is to read the PID/VID of the device to
# determine which registers it supports. However, PCI devices have not
# been scanned at this point in init, so it would require scanning PCI
# config space directly and I don't yet see the point of doing that.
#
# Oh, and the UNEXPECTED_IO_APIC() function doesn't print anything in
# 2.5.current and I didn't change that.

# This patch adds an AT_SECURE auxv entry to pass a boolean flag indicating
# whether "secure mode" should be enabled (i.e. sanitize the environment,
# initial descriptors, etc) and allows each security module to specify the
# flag value via a new hook.
#
# New userland can then simply obey this flag when present rather than
# applying other methods of deciding (sample patch for glibc-2.3.2 can be
# found at http://www.cs.utah.edu/~sds/glibc-secureexec.patch).
#
# This change enables security modules like SELinux to request secure mode
# upon changes to other security attributes (e.g. capabilities,
# roles/domains, etc) in addition to uid/gid changes or even to completely
# override the legacy logic.
#
# The legacy decision algorithm is preserved in the default hook functions
# for the dummy and capability security modules.
#
# Credit for the idea of adding an AT_SECURE auxv entry goes to Roland
# McGrath.

# [PATCH] get_unmapped_area() speedup
#
# From: Ingo Molnar
#
# Apparently our thread-creation performance has gone down the tubes again,
# because the mm.free_area_cache search heuristic broke.
#
# The initial, more naive hole-cache patch helped the testcode in the
# beginning. Then after some point glibc started creating a 'small hole' in
# the vmas, which hole was _below_ the thread stacks, and which hole thus
# prevented the intended operation of the cache.
#
# The new code solves the problem by relaxing the 'smallest address hole cache'
# rule a bit, the cache is now not re-set at every get_unmapped_area() time,
# it's only re-set during unmaps. It's also re-set if there are no allocatable
# mappings at all - ie. correctness is not affected.

# [PATCH] dentry->d_count fixes: d_invalidate
#
# From: Maneesh Soni <maneesh@in.ibm.com>

# [PATCH] dentry->d_count fixes: nfs_unlink
#
# From: Maneesh Soni <maneesh@in.ibm.com>
#
# - nfs_unlink() can race with lockless d_lookup() as d_lookup() can
# successfully lookup a dentry for which nfs_unlink() can assume that no one
# else is using and can go ahead and do nfs_safe_remove() on it. By using
# per dentry lock, it is solved as we d_lookup() will fail the lookup for
# unhashed dentries.

# - hpfs_unlink() can race with lockless d_lookup(), as we can have situations
# where d_lookup() has successfully looked-up a dentry and at the sametime
# hpfs_unlink()--->d_drop() has dropped it. Taking the per dentry lock
# before checking the d_count in hpfs_unlink() solves this race condition.

# [PATCH] workaround for smb_proc_getattr oops
#
# From: Zwane Mwaikambo <zwane@linuxpower.ca>
#
# smbfs tends to oops over a null server->ops->getattr in smb_proc_getattr().
#
# Urban says:
#
# In 2.5 the server->ops is initialized when smbfs gets a connection, to
# match whatever the server is capable of or not. This happens after the
# mount syscall so smbfs is then mounted but not usable.
#
# Not sure if smb_lookup is always called before any other operation that
# uses server->ops. If it is then it would be enough to have a test there.
#
# Otherwise I will just change all users of server->ops to verify the
# pointer first and return -EIO or something.
#
# Al Viro says (paraphrasing)
#
# ugh, we need mount2().
#
# It doesn't look to me like we'll be getting mount2() in the 2.6 timeframe.
# Zwane's patch implement's Urban's workaround.

# [PATCH] normalise node load for NUMA
#
# From: Andrew Theurer <habanero@us.ibm.com>
#
# This patch ensures that when node loads are compared, the load value is
# normalised. Without this, load balance across nodes of dissimilar cpu
# counts can cause unfairness and sometimes lower overall performance.
#
# For example, a 2 node system with 4 cpus in the first node and 2 cpus in
# the second. A workload with 6 running tasks would have 3 tasks running on
# one node and 3 on the other, leaving one cpu idle in the first node and two
# tasks sharing a cpu in the second node. The patch would ensure that 4
# tasks run in the first node and 2 in the second.
#
# I ran some kernel compiles comparing this patch on a 2 node 4 cpu/2 cpu
# system to show the benefits. Without the patch I got 140 second elapsed
# time. With the patch I get 132 seconds (6% better).
#
# Although it is not very common to have nodes with dissimilar cpu counts, it
# is already happening. PPC64 systems with partitioning have this happen,
# and I expect it to be more common on ia32 as partitioning becomes more
# common.

# [PATCH] ext3: fix page lock vs journal_start ranking bug
#
# ext3_block_truncate_page() is calling grab_cache_page() inside a JBD
# transaction. This is wrong, because transactions nest inside lock_page().
#
# The deadlock is against shrink_list->ext3_journalled_writepage->journal_start.
#
# This was not noticed before because we never used to journal writepage() data
# in journalled-data mode. And because the deadlock against
# generic_file_write() is covered up by i_sem.
#
# Rework things so that we lock the page prior to starting a transaction.

# strip the buffers and free the page even if it was not marked buffer_freed().

# [PATCH] Use Local Percpu Macros for Local Percpu Variables
#
# In general, it is more better to use get_cpu_var() and __get_cpu_var()
# to access per-cpu variables on this CPU than to use smp_processor_id()
# and per_cpu(). In the current default implemention they are equivalent,
# but on IA64 the former is already faster, and other archs will follow.

-a front-matter section of the Document that deals exclusively with the
-relationship of the publishers or authors of the Document to the
-Document's overall subject (or to related matters) and contains nothing
-that could fall directly within that overall subject. (Thus, if the
-Document is in part a textbook of mathematics, a Secondary Section may

-Sections whose titles are designated, as being those of Invariant
-Sections, in the notice that says that the Document is released under

-Secondary then it is not allowed to be designated as Invariant. The
-Document may contain zero Invariant Sections. If the Document does not

-composed of pixels) generic paint programs or (for drawings) some widely
-available drawing editor, and that is suitable for input to text

-for input to text formatters. A copy made in an otherwise Transparent
-file format whose markup, or absence of markup, has been arranged to

-Document's license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover Texts:
-Front-Cover Texts on the front cover, and Back-Cover Texts on the back
-cover. Both covers must also clearly and legibly identify you as the
-publisher of these copies. The front cover must present the full title
-with all words of the title equally prominent and visible. You may add
-other material on the covers in addition. Copying with changes limited
-to the covers, as long as they preserve the title of the Document and
-satisfy these conditions, can be treated as verbatim copying in other
-respects.</para>
-
-<para>If the required texts for either cover are too voluminous to fit

-numbering more than 100, you must either include a machine-readable
-Transparent copy along with each Opaque copy, or state in or with each
-Opaque copy a computer-network location from which the general
-network-using public has access to download using public-standard
-network protocols a complete Transparent copy of the Document, free of
-added material. If you use the latter option, you must take reasonably
-prudent steps, when you begin distribution of Opaque copies in quantity,
-to ensure that this Transparent copy will remain thus accessible at the
-stated location until at least one year after the last time you
-distribute an Opaque copy (directly or through your agents or retailers)

-documents released under this License, and replace the individual copies
-of this License in the various documents with a single copy that is
-included in the collection, provided that you follow the rules of this
-License for verbatim copying of each of the documents in all other

-
-<para>A compilation of the Document or its derivatives with other
-separate and independent documents or works, in or on a volume of a
-storage or distribution medium, is called an "aggregate" if the
-copyright resulting from the compilation is not used to limit the legal
-rights of the compilation's users beyond what the individual works
-permit. When the Document is included an aggregate, this License does
-not apply to the other works in the aggregate which are not themselves
-derivative works of the Document.</para>
-
-<para>If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document's Cover Texts may be placed on covers
-that bracket the Document within the aggregate, or the electronic
-equivalent of covers if the Document is in electronic form. Otherwise
-they must appear on printed covers that bracket the whole
-aggregate.</para>
-</sect1>

-<sect1 id="gfdl-8"><title>TRANSLATION</title>
-
-<para>Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers. In case of a disagreement between the
-translation and the original version of this License or a notice or
-disclaimer, the original version will prevail.</para>
-
-<para>If a section in the Document is Entitled "Acknowledgements",
-"Dedications", or "History", the requirement (section 4) to Preserve its
-Title (section 1) will typically require changing the actual
-title.</para>

-<sect1 id="gfdl-9"><title>TERMINATION</title>
-
-<para>You may not copy, modify, sublicense, or distribute the Document
-except as expressly provided for under this License. Any other attempt
-to copy, modify, sublicense or distribute the Document is void, and will
-automatically terminate your rights under this License. However,

- Note that the answer to this question doesn't directly affect the
- kernel: saying N will just cause the configurator to skip all
- the questions about these CD-ROM drives. If you are unsure what you
- have, say Y and find out whether you have one of the following
- drives.
-
- For each of these drivers, a file Documentation/cdrom/{driver_name}
- exists. Especially in cases where you do not know exactly which kind
- of drive you have you should read there. Most of these drivers use a
- file drivers/cdrom/{driver_name}.h where you can define your
- interface parameters and switch some internal goodies.
-
- All these CD-ROM drivers are also usable as a module ( = code which
- can be inserted in and removed from the running kernel whenever you
- want). If you want to compile them as module, say M instead of Y and
- read <file:Documentation/modules.txt>.
-
- If you want to use any of these CD-ROM drivers, you also have to
- answer Y or M to "ISO 9660 CD-ROM file system support" below (this
- answer will get "defaulted" for you if you enable any of the Linux
- CD-ROM drivers).

- The frame buffer device provides an abstraction for the graphics

- anything about the low-level (hardware register) stuff.
-
- Frame buffer devices work identically across the different

- On several non-X86 architectures, the frame buffer device is the
- only way to use the graphics hardware.
-
- The device is accessed through special device nodes, usually located
- in the /dev directory, i.e. /dev/fb*.

- buffer devices. Please read <file:Documentation/fb/framebuffer.txt>

- want to play with it, but it is not essential. Please note that
- running graphical applications that directly touch the hardware
- (e.g. an accelerated X server) and that are not frame buffer
- device-aware may cause unexpected results. If unsure, say N.

+ ---help---
+ The frame buffer device provides an abstraction for the graphics
+ hardware. It represents the frame buffer of some video hardware and
+ allows application software to access the graphics hardware through
+ a well-defined interface, so the software doesn't need to know
+ anything about the low-level (hardware register) stuff.
+
+ Frame buffer devices work identically across the different
+ architectures supported by Linux and make the implementation of
+ application programs easier and more portable; at this point, an X
+ server exists which uses the frame buffer device exclusively.
+ On several non-X86 architectures, the frame buffer device is the
+ only way to use the graphics hardware.
+
+ The device is accessed through special device nodes, usually located
+ in the /dev directory, i.e. /dev/fb*.
+
+ You need an utility program called fbset to make full use of frame
+ buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
+ and the Framebuffer-HOWTO at
+ <http://www.tahallah.demon.co.uk/programming/prog.html> for more
+ information.
+
+ Say Y here and to the driver for your graphics board below if you
+ are compiling a kernel for a non-x86 architecture.
+
+ If you are compiling for the x86 architecture, you can say Y if you
+ want to play with it, but it is not essential. Please note that
+ running graphical applications that directly touch the hardware
+ (e.g. an accelerated X server) and that are not frame buffer
+ device-aware may cause unexpected results. If unsure, say N.

- * 1 Software (ignored)

- * 3 Local IRQ level one
- * 4 8254 Timer zero
- * 5 8254 Timer one
- * 6 Bus Error
- * 7 R4k timer (what we use)
- *
- * We handle the IRQ according to _our_ priority which is:
- *
- * Highest ---- R4k Timer
- * Local IRQ zero
- * Local IRQ one
- * Bus Error
- * 8254 Timer zero
- * Lowest ---- 8254 Timer one

- * This file contains common PCI routines meant to be shared for
- * all MIPS machines.
- *
- * Strategies:
- *
- * . We rely on pci_auto.c file to assign PCI resources (MEM and IO)
- * TODO: this should be optional for some machines where they do have
- * a real "pcibios" that does resource assignment.
- *
- * . We then use pci_scan_bus() to "discover" all the resources for
- * later use by Linux.
- *
- * . We finally reply on a board supplied function, pcibios_fixup_irq(), to
- * to assign the interrupts. We may use setup-irq.c under drivers/pci
- * later.
- *
- * . Specifically, we will *NOT* use pci_assign_unassigned_resources(),
- * because we assume all PCI devices should have the resources correctly
- * assigned and recorded.
- *
- * Limitations:
- *
- * . We "collapse" all IO and MEM spaces in sub-buses under a top-level bus
- * into a contiguous range.
- *
- * . In the case of Memory space, the rnage is 1:1 mapping with CPU physical
- * address space.
- *
- * . In the case of IO space, it starts from 0, and the beginning address
- * is mapped to KSEG0ADDR(mips_io_port) in the CPU physical address.
- *
- * . These are the current MIPS limitations (by ioremap, etc). In the
- * future, we may remove them.
- *
- * Credits:
- * Most of the code are derived from the pci routines from PPC and Alpha,
- * which were mostly writtne by
- * Cort Dougan, cort@fsmlabs.com
- * Matt Porter, mporter@mvista.com
- * Dave Rusling david.rusling@reo.mts.dec.com

- * it so that at startup, the timer code in sched.c would select
- * using either the RTC or the 8253 timer. The decision would be
- * based on whether there was any other device around that needed
- * to trample on the 8253. I'd set up the RTC to interrupt at 1024 Hz,
- * and then do some jiggery to have a version of do_timer that
- * advanced the clock by 1/1024 s. Every time that reached over 1/100
- * of a second, then do all the old code. If the time was kept correct
- * then do_gettimeoffset could just return 0 - there is no low order
- * divider that can be accessed.

- * This file contains common PCI routines meant to be shared for
- * all MIPS machines.
- *
- * Strategies:
- *
- * . We rely on pci_auto.c file to assign PCI resources (MEM and IO)
- * TODO: this should be optional for some machines where they do have
- * a real "pcibios" that does resource assignment.
- *
- * . We then use pci_scan_bus() to "discover" all the resources for
- * later use by Linux.
- *
- * . We finally reply on a board supplied function, pcibios_fixup_irq(), to
- * to assign the interrupts. We may use setup-irq.c under drivers/pci
- * later.
- *
- * . Specifically, we will *NOT* use pci_assign_unassigned_resources(),
- * because we assume all PCI devices should have the resources correctly
- * assigned and recorded.
- *
- * Limitations:
- *
- * . We "collapse" all IO and MEM spaces in sub-buses under a top-level bus
- * into a contiguous range.
- *
- * . In the case of Memory space, the rnage is 1:1 mapping with CPU physical
- * address space.
- *
- * . In the case of IO space, it starts from 0, and the beginning address
- * is mapped to KSEG0ADDR(mips_io_port) in the CPU physical address.
- *
- * . These are the current MIPS limitations (by ioremap, etc). In the
- * future, we may remove them.
- *
- * Credits:
- * Most of the code are derived from the pci routines from PPC and Alpha,
- * which were mostly writtne by

+ *
+ * 2001-10-26 Bradley D. LaRonde <brad@ltc.com>
+ * - Add a top_bus argument to the "early config" functions so that

+ * pci ops to use type 1 configuration for sub busses.
+ * - Set bridge base and limit registers correctly.
+ * - Align io and memory base properly before and after bridge setup.
+ * - Don't fall through to pci_setup_bars for bridge.
+ * - Reformat the debug output to look more like lspci's output.

+ * This file contains common PCI routines meant to be shared for
+ * all MIPS machines.
+ *
+ * Strategies:
+ *
+ * . We rely on pci_auto.c file to assign PCI resources (MEM and IO)
+ * TODO: this should be optional for some machines where they do have
+ * a real "pcibios" that does resource assignment.
+ *
+ * . We then use pci_scan_bus() to "discover" all the resources for
+ * later use by Linux.
+ *
+ * . We finally reply on a board supplied function, pcibios_fixup_irq(), to
+ * to assign the interrupts. We may use setup-irq.c under drivers/pci
+ * later.
+ *
+ * . Specifically, we will *NOT* use pci_assign_unassigned_resources(),
+ * because we assume all PCI devices should have the resources correctly
+ * assigned and recorded.
+ *
+ * Limitations:
+ *
+ * . We "collapse" all IO and MEM spaces in sub-buses under a top-level bus
+ * into a contiguous range.
+ *
+ * . In the case of Memory space, the rnage is 1:1 mapping with CPU physical
+ * address space.
+ *
+ * . In the case of IO space, it starts from 0, and the beginning address
+ * is mapped to KSEG0ADDR(mips_io_port) in the CPU physical address.
+ *
+ * . These are the current MIPS limitations (by ioremap, etc). In the
+ * future, we may remove them.
+ *
+ * Credits:
+ * Most of the code are derived from the pci routines from PPC and Alpha,
+ * which were mostly writtne by
+ * Cort Dougan, cort@fsmlabs.com
+ * Matt Porter, mporter@mvista.com
+ * Dave Rusling david.rusling@reo.mts.dec.com

+7. Too many CLIs in the locore handlers :

+__tlb_refill_debug_tramp, __xtlb_refill_debug_tramp and cacheerror,
+investigate whether the code should do CLI, STI or KMODE.
+8. Too many do_page_faults invoked - investigate.
+9. start_thread must turn off UX64 ... and define tlb_refill_debug.

- ---help---
- The Extended Industry Standard Architecture (EISA) bus was
- developed as an open alternative to the IBM MicroChannel bus.
-
- The EISA bus provided some of the features of the IBM MicroChannel
- bus while maintaining backward compatibility with cards made for
- the older ISA bus. The EISA bus saw limited use between 1988 and
- 1995 when it was made obsolete by the PCI bus.
-
- Say Y here if you are building a kernel for an EISA-based machine.

- of binutils or on some architectures.
-
- This is especially useful if you have compiled the kernel with the

- the modular sound system is contained in the files
- <file:Documentation/sound/Introduction>. The file

- outdated but still useful information as well.
-
- If you have a PnP sound card and you want to configure it at boot
- time using the ISA PnP tools (read
- <http://www.roestock.demon.co.uk/isapnptools/>), then you need to
- compile the sound card support as a module ( = code which can be

- and load that module after the PnP configuration is finished. To do
- this, say M here and read <file:Documentation/modules.txt> as well
- as <file:Documentation/sound/README.modules>; the module will be
- called soundcore.
-
- I'm told that even without a sound card, you can make your computer
- say more than an occasional beep, by programming the PC speaker.
- Kernel patches and supporting utilities to do that are in the pcsp
- package, available at <ftp://ftp.infradead.org/pub/pcsp/>.

- *
- * cp1emu.c: a MIPS coprocessor 1 (fpu) instruction emulator
- *
- * A complete emulator for MIPS coprocessor 1 instructions. This is
- * required for #float(switch) or #float(trap), where it catches all
- * COP1 instructions via the "CoProcessor Unusable" exception.
- *
- * More surprisingly it is also required for #float(ieee), to help out
- * the hardware fpu at the boundaries of the IEEE-754 representation
- * (denormalised values, infinities, underflow, etc). It is made
- * quite nasty because emulation of some non-COP1 instructions is
- * required, e.g. in branch delay slots.
- *
- * Notes:
- * 1) the IEEE754 library (-le) performs the actual arithmetic;
- * 2) if you know that you won't have an fpu, then you'll get much
- * better performance by compiling with -msoft-float!
- *
- * Nov 7, 2000
- * Massive changes to integrate with Linux kernel.
- *
- * Replace use of kernel data area with use of user stack
- * for execution of instructions in branch delay slots.
- *
- * Replace use of static kernel variables with thread_struct elements.

+ If you have a CD-ROM drive that is neither SCSI nor IDE/ATAPI, say Y
+ here, otherwise N. Read the CD-ROM-HOWTO, available from
+ <http://www.tldp.org/docs.html#howto>.
+
+ Note that the answer to this question doesn't directly affect the
+ kernel: saying N will just cause the configurator to skip all
+ the questions about these CD-ROM drives. If you are unsure what you
+ have, say Y and find out whether you have one of the following
+ drives.
+
+ For each of these drivers, a file Documentation/cdrom/{driver_name}
+ exists. Especially in cases where you do not know exactly which kind
+ of drive you have you should read there. Most of these drivers use a
+ file drivers/cdrom/{driver_name}.h where you can define your
+ interface parameters and switch some internal goodies.
+
+ All these CD-ROM drivers are also usable as a module ( = code which
+ can be inserted in and removed from the running kernel whenever you
+ want). If you want to compile them as module, say M instead of Y and
+ read <file:Documentation/modules.txt>.
+
+ If you want to use any of these CD-ROM drivers, you also have to
+ answer Y or M to "ISO 9660 CD-ROM file system support" below (this
+ answer will get "defaulted" for you if you enable any of the Linux
+ CD-ROM drivers).

+ This is the driver for the SMB Host controller on
+ Acer Labs Inc. (ALI) M1535 South Bridge.
+
+ The M1535 is a South bridge for portable systems.
+ It is very similar to the M15x3 South bridges also produced
+ by Acer Labs Inc. Some of the registers within the part
+ have moved and some have been redefined slightly. Additionally,
+ the sequencing of the SMBus transactions has been modified
+ to be more consistent with the sequencing recommended by
+ the manufacturer and observed through testing. These
+ changes are reflected in this driver and can be identified
+ by comparing this driver to the i2c-ali15x3 driver.
+ For an overview of these chips see http://www.acerlabs.com
+
+ The SMB controller is part of the 7101 device, which is an
+ ACPI-compliant Power Management Unit (PMU).
+
+ The whole 7101 device has to be enabled for the SMB to work.
+ You can't just enable the SMB alone.
+ The SMB and the ACPI have separate I/O spaces.
+ We make sure that the SMB is enabled. We leave the ACPI alone.
+
+ This driver controls the SMB Host only.
+
+ This driver does not use interrupts.

+ help
+ Say Y here if you want to use the fake PCI hotplug driver. It can
+ be used to simulate PCI hotplug events if even if your system is
+ not PCI hotplug capable.
+
+ This driver will "emulate" removing PCI devices from the system.
+ If the "power" file is written to with "0" then the specified PCI
+ device will be completely removed from the kernel.
+
+ WARNING, this does NOT turn off the power to the PCI device.
+ This is a "logical" removal, not a physical or electrical
+ removal.
+
+ Use this module at your own risk. You have been warned!
+
+ This code is also available as a module ( = code which can be
+ inserted in and removed from the running kernel whenever you want).
+ The module will be called fakephp. If you want to compile it
+ as a module, say M here and read <file:Documentation/modules.txt>.
+
+ When in doubt, say N.

- * DS1286 Real Time Clock interface for Linux
- *
- * Copyright (C) 1998, 1999, 2000 Ralf Baechle
- *
- * Based on code written by Paul Gortmaker.
- *
- * This driver allows use of the real time clock (built into nearly all
- * computers) from user space. It exports the /dev/rtc interface supporting
- * various ioctl() and also the /proc/rtc pseudo-file for status
- * information.
- *
- * The ioctls can be used to set the interrupt behaviour and generation rate
- * from the RTC via IRQ 8. Then the /dev/rtc interface can be used to make
- * use of these timer interrupts, be they interval or alarm based.
- *
- * The /dev/rtc interface will block on reads until an interrupt has been
- * received. If a RTC interrupt has already happened, it will output an
- * unsigned long and then block. The output value contains the interrupt
- * status in the low byte and the number of interrupts since the last read
- * in the remaining high bytes. The /dev/rtc interface can also be used with
- * the select(2) call.
- *
- * This program is free software; you can redistribute it and/or modify it
- * under the terms of the GNU General Public License as published by the
- * Free Software Foundation; either version 2 of the License, or (at your
- * option) any later version.

- *
- * From a mail with Mark J. Kilgard, /dev/opengl and /dev/graphics are

- *
- * The reason that the original SGI programmer had to use only one
- * device for all the graphic cards on the system will remain a
- * mistery for the rest of our lives. Why some ioctls take a board
- * number and some others not? Mistery. Why do they map the hardware
- * registers into the user address space with an ioctl instead of
- * mmap? Mistery too. Why they did not use the standard way of
- * making ioctl constants and instead sticked a random constant?
- * Mistery too.
- *
- * We implement those misterious things, and tried not to think about

- * written 1997 Miguel de Icaza (miguel@nuclecu.unam.mx)
- *
- * We implement /dev/shmiq, /dev/qcntlN here
- * this is different from IRIX that has shmiq as a misc
- * streams device and the and qcntl devices as a major device.
- *
- * minor number 0 implements /dev/shmiq,
- * any other number implements /dev/qcntl${minor-1}
- *
- * /dev/shmiq is used by the X server for two things:
- *
- * 1. for I_LINK()ing trough ioctl the file handle of a
- * STREAMS device.
- *
- * 2. To send STREAMS-commands to the devices with the
- * QIO ioctl interface.
- *
- * I have not yet figured how to make multiple X servers share
- * /dev/shmiq for having different servers running. So, for now
- * I keep a kernel-global array of inodes that are pushed into
- * /dev/shmiq.
- *
- * /dev/qcntlN is used by the X server for two things:
- *
- * 1. Issuing the QIOCATTACH for mapping the shared input
- * queue into the address space of the X server (yeah, yeah,
- * I did not invent this interface).
- *
- * 2. used by select. I bet it is used for checking for events on
- * the queue.
- *
- * Now the problem is that there does not seem anything that
- * establishes a connection between /dev/shmiq and the qcntlN file. I
- * need an strace from an X server that runs on a machine with more
- * than one keyboard. And this is a problem since the file handles
- * are pushed in /dev/shmiq, while the events should be dispatched to
- * the /dev/qcntlN device.
- *
- * Until then, I just allow for 1 qcntl device.

- * usema.c: software semaphore driver (see IRIX's usema(7M))
- * written 1997 Mike Shaver (shaver@neon.ingenia.ca)
- * 1997 Miguel de Icaza (miguel@kernel.org)
- *
- * This file contains the implementation of /dev/usemaclone,
- * the devices used by IRIX's us* semaphore routines.
- *
- * /dev/usemaclone is used to create a new semaphore device, and then
- * the semaphore is manipulated via ioctls.
- *
- * At least for the zero-contention case, lock set and unset as well
- * as semaphore P and V are done in userland, which makes things a
- * little bit better. I suspect that the ioctls are used to register
- * the process as blocking, etc.
- *
- * Much inspiration and structure stolen from Miguel's shmiq work.
- *
- * For more information:
- * usema(7m), usinit(3p), usnewsema(3p)

+ * MAC register, and there will be a MAC_REGISTER() macro
+ * to calculate the base address of a given MAC.

- * These are probably defined overly paranoid ...
+ * read_barrier_depends - Flush all pending reads that subsequents reads
+ * depend on.
+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier. All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads. This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies. See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ * CPU 0 CPU 1
+ *
+ * b = 2;
+ * memory_barrier();
+ * p = &b; q = p;
+ * read_barrier_depends();
+ * d = *q;
+ * </programlisting>
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends(). However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ * CPU 0 CPU 1
+ *
+ * a = 2;
+ * memory_barrier();
+ * b = 3; y = b;
+ * read_barrier_depends();
+ * x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b". Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
+ * in cases like thiswhere there are no data dependencies.

+ * Naming schemes for constants in these files:
+ *
+ * M_xxx MASK constant (identifies bits in a register).
+ * For multi-bit fields, all bits in the field will
+ * be set.
+ *
+ * K_xxx "Code" constant (value for data in a multi-bit
+ * field). The value is right justified.
+ *
+ * V_xxx "Value" constant. This is the same as the
+ * corresponding "K_xxx" constant, except it is
+ * shifted to the correct position in the register.
+ *
+ * S_xxx SHIFT constant. This is the number of bits that
+ * a field value (code) needs to be shifted
+ * (towards the left) to put the value in the right
+ * position for the register.
+ *
+ * A_xxx ADDRESS constant. This will be a physical
+ * address. Use the PHYS_TO_K1 macro to generate
+ * a K1SEG address.
+ *
+ * R_xxx RELATIVE offset constant. This is an offset from
+ * an A_xxx constant (usually the first register in
+ * a group).
+ *
+ * G_xxx(X) GET value. This macro obtains a multi-bit field
+ * from a register, masks it, and shifts it to
+ * the bottom of the register (retrieving a K_xxx
+ * value, for example).
+ *
+ * V_xxx(X) VALUE. This macro computes the value of a
+ * K_xxx constant shifted to the correct position
+ * in the register.

+ * on IRIX to see where the sections go. The Origin loader loads
+ * the two sections contiguously in physical memory. The loader

+ * 0xa800000000160000, which is where it physically loaded that
+ * code. So no jumps can be done before we have switched to using

- * These are probably defined overly paranoid ...
+ * read_barrier_depends - Flush all pending reads that subsequents reads
+ * depend on.
+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier. All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads. This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies. See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ * CPU 0 CPU 1
+ *
+ * b = 2;
+ * memory_barrier();
+ * p = &b; q = p;
+ * read_barrier_depends();
+ * d = *q;
+ * </programlisting>
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends(). However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ * CPU 0 CPU 1
+ *
+ * a = 2;
+ * memory_barrier();
+ * b = 3; y = b;
+ * read_barrier_depends();
+ * x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b". Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
+ * in cases like thiswhere there are no data dependencies.
