This patch fixes a long-standing (albeit unidentified) problem in the
queueing code for the UHCI HCD.  The code propagates data toggle settings
between messages in a queue for control transfers just the same as bulk
and interrupt transfers.  That is a mistake, since control messages always
restart with data toggle 0.  With this patch, the UHCI driver now passes
test 10 (control URB queueing) in David Brownell's usbtest suite.

The patch appears to change more than it really does, because it alters
the indentation level of a large section of code.

non-fatal didn't get the same change that k7.c did a few months
back, so it reads from banks that actually _cause_ MCEs.

This patch also adds a bunch of copyright headers whilst we're
in that neighborhood.

In particular, load the host early in order to do proper
locking without having to access the command structure later.

This patch arranges for the exception tables to be sorted on most
architectures.  It sorts the main kernel exception table on startup
and the module exception tables when they get loaded.  The main table
is sorted reasonably early - just after kmem_cache_init - but that
could be moved even earlier if necessary.

There is now a lib/extable.c which includes the sort_extable()
function from arch/ppc/mm/extable.c and the search_extable() function
from arch/i386/mm/extable.c, which had been copied to many
architectures.  On many architectures, arch/$(ARCH)/mm/extable.c
became empty and so I have removed it.

There are four architectures which do things differently from i386:
alpha, ia64, sparc and sparc64.  Alpha and ia64 store the offset from
the offset from the exception table entry to the instruction, and
sparc and sparc64 have range entries in the table.  For those
architectures I have added empty sort_extable functions.  The
maintainers for those architectures can implement something better if
they care to.  As it is they are no worse off than before.

Although it is a moderately sizable patch, it ends up with a net
reduction of 377 lines in the size of the kernel source. :)

I have tested this on x86 and ppc with a module that uses __get_user
in an init function, deliberately laid out to get the exception table
out of order, and it works (whereas it oopsed without this patch).

This went missing somewhere.  Here's a patch which puts it back.

Sanitize 66MHz clock use: "enable" 66MHz clock before starting UDMA3/4/5
read/write transfer and "disable" it after finishing transfer.

- fixes timings for non-UDMA3/4/5 operations (correct 33MHz timings are used)

- allows using UDMA3/4/5 modes on a capable drive even if non-UDMA3/4/5 drive
  is present on the same channel

- fixes corner case when one drive on the channel was using UDMA66/100 + LBA48
  (so clock was enabled/disabled for each read/write) and other one was using
  UDMA66/100 + LBA28, it could happen that request on LBA48 drive disabled
  66MHz clock and it was not enabled for the next transfer on LBA28 drive

drive->id is now always present even if no device is attached,
therefore check for drive->present instead.

This fixes bugzilla bug #1431.

Always tune controller PIO timings.  This fixes lockup during PIO access
(ie. 'cat /proc/ide/hda/identify') when Promise BIOS is disabled.

When binding to a link-local address, inet6_bind() and raw6_bind() only
check that an interface is specified and that the address exists, but
they don't check if it actually exists on the specified interface.

Similarly, in datagram_sent_ctl() we don't check for the possibility of a
link-local address when we receive the source address from userspace.

The v3 reiserfs_file_write func doesn't do any write throttling, which
leads to a variety of problems.  Here's a patch that makes
reiserfs_file_write call balance_dirty_pages_ratelimited, and exports that
func for module usage.

Remove now-unused 2.4 back-compat code.

gcc miscompiles this. Scary.

- A couple of them are using alloca (via DECLARE_BITMAP) and this generates
  a cannot-inline warning with -Winline.

- These functions are too big to inline anwyay.

Everything freezes when trying to play sounds using the alsa driver opl3sa2
(kernel supplied or 1.0.0rc2) on an Acer Extensa series laptop with the Ali
M1533 PCI to ISA bridge.  Problem exists both in the 2.6 and 2.4 series of
kernels.

Adding AL_M1533 to drivers/pci/quirks.c fixes the problem for both.  This has
been a known problem since 2.2.x (see

Here's a patch to improve the AFS linux support. It:

 (1) Includes Pete's patch to skip the colon in the volume name, compile
     directly into the kernel, and not try to access non-existent caching
     routines.

 (2) Changes if (...) BUG() to BUG_ON()

 (3) Gets rid of typedefs.

 (4) Changes list_for_each() into list_for_each_entry().

 (5) Adds more whitespace and wraps lines to please the CodingStyle sticklers.

The included patch removes the usage of weak symbols from sgiioc4.c now
that we have the Kconfig issue sorted as well as cleans up the error no
handling (instead of return 1 on error) and adds a check for the return

Within the body of this macro we are accessing rq->bio, but `bio' is an arg
to the macro.  If someone uses this macro with some variable which is not
named `bio' it won't compile.

So use a more-likely-to-be-unique identifier for the macro.

Experimenting with trying to use cond_syscall for a few arch-specific
syscalls, I discovered that it can't actually be used outside the file
in which sys_ni_syscall is declared because the assembler doesn't feel
obliged to output the symbol in that case:

weak.c:

#define cond_syscall(x) asm(".weak\t" #x "\n\t.set\t" #x ",sys_ni_syscall");
cond_syscall(sys_foo);

$ nm weak.o
         U sys_ni_syscall

One arch (PPC) is apparently trying to use cond_syscall this way
anyway, though it's probably never been actually tested as the above
test was done on a PPC.

After trying a bunch of tricks to get it to work nicely, I decided
there are basically two alternatives: make weak versions of
sys_ni_syscall wherever they're wanted or put the arch-specific
cond_syscalls in kernel/sys.c where sys_ni_syscall is defined.

The former approach is a bit crufty and doesn't actually do the right
thing in practice as you'll get multiple copies of sys_ni_syscall in
your final image.

The latter introduces some slight arch-pollution in sys.c, but as
arch-specific cond_syscalls aren't all that frequent, it should be
pretty minor. So here's a patch to move the current offender to sys.c:
