(fixes crash)

This forward-ports some more of the ALI IDE sanity checks from the 2.4.x
tree. 

In particular, we only do the enable bits for revisions < 0xC5

We've resolved some bugs in legacy ALi5455 audio driver.

This leaves just the minimal oops protection in place, and
maintains the logic that "if we have a non-ALI northbridge,
we shouldn't touch any of the GPIOs because we don't know
what they might be connected to".

	signal handler.  Otherwise, a restarted system call that gets
	interrupted before the restart has taken effect by _another_
	signal will potentially restart the wrong system call.

Otherwise, a restarted system call that gets interrupted before
the restart has taken effect by _another_ signal will potentially
restart the wrong system call.

It would oops on any machines that had an ALI northbridge but
didn't have the exact ISA bridge we expected.

The problem with clock_nanosleep() restarting was that the address of
the users return timespec was being saved at the wrong place.  In needs
to be saved in the sys call interface code rather than the
do_clock_nanosleep().  My original tests were a bit weak as they only
did one signal rather than two or more which were required to break it. 

The attached patch fixes the problem.

I also added a few comments about how restart works, and added my name
to the MAINTAINERS list.

Without this patch, SN machines which have nodes that contain memory only (no
CPUs will hang.

The bug is probably impossible to trigger on x86, due to its
fairly strong coherency model (the SMP-safe bitops end up being
memory barriers etc), but other architectures - notably ppc64 -
can apparently trigger a race whereby the signal sender doesn't
wake up the target because it doesn't notice that it has gone to
sleep.

The optimization also optimizes only what appears to be the
uncommon case, where the signal happens for an already-running
process.

This makes the AIO submit path holds an extra reference until just
before returning.  This fixes the referencing a free kiocb. 

Without this patch the kernel will oops if the AIO completes early.

Noticed by Petr Vandrovec.

In the out-of-memory case, do_wp_page() would unlock page_table_lock
twice - once before allocating, and once in the exit path.

Rewrite the exit paths to be more readable, and don't try to share
the code between all the exit cases, since they are very different. 

- Delete fd_{enable,disable}_irq() interfaces, never used.
- Move ebus_dma_irq_enable() calls into sun_pci_fd_{request,free}_irq().

Display of cpumask for /proc/irq/prof_cpu_mask has a botch in the print
loop - should consume 2 bytes per loop.

Since 2.6.x by default does not remap the disk partitions any more, it
would be a good idea to warn when we see EZD or DM signatures.  That
informs the user to fix his setup (or pass in "hdx=remap" on the kernel
command line).

The cpu_callout_map differs from the prototype in asm-i386/smp.h by a
volatile.  gcc-3.3 now treats this as an error, so voyager support will
only compile with older gcc's.  The fix is to remove the spurious volatile.

This fixes a JBD assertion failure (goes BUG) in __journal_remove_journal_head().

When the journal had aborted due to earlier internal consistency errors (or
I/O errors) it is possible that we free journal_heads which still have
attached copyout buffers.  So just free them up.

This fixes the RAID1 recovery problems; it seems to be a simple thinko:
sync_request_write() is passing "ok=0" into md_done_sync().  Clearly, `ok'
should be true here.

From: Rusty Russell <rusty@rustcorp.com.au>

Module aliases are all of form "char-major-<major>-<minor>".  char_dev.c
calls request_module with "char-major-<major>".

It's not ready for prime time yet, so hide it until the additional work has
been done.

If this CPU decides that an ext2 block group has a free block it will then go
in and try to acquire it.  No locks are held, so another CPU can come in and
steal the last block.

In this case we will bogusly report a corrupted filessytem.

Fix it by just restarting the scan - this will choose a different blockgroup
or will generate -ENOSPC.

Only include mca.h if CONFIG_MCA: only ia32 and ia64 have <asm/mca.h>

From: Nick Piggin <piggin@cyberone.com.au>

as_completed_request() can be called for requests which were not generated by
the generic block layer.  Handle these, to avoid a subsequent WARN_ON (at
least).

Also kill a separate WARN_ON which is bogusly triggering.

An extra dput was introduced in nfsd_rename 20 months ago....

time to remove it.

The __start___ex_table and __start___bug_table symbols could end up
pointing a few bytes before the actual __ex_table and __bug_table
sections, if the preceding section had an odd length.  This led to
oopses in some situations.  Patch from Sam Ravnborg.
