Early ACPI table parse for HPET tables has a bug, where in it
does not do proper set_fixmap for ACPI-HPET table.

This bug was lost in oversight, and was not noticed during
my testing too, as the ACPI-HPET table on all my test
systems happened to be in 1st Gig of memory (where __va()
will do the job).

The 2.4 megaraid driver recognizes the Intel PCI vendor id whereas the
2.6 driver does not.  The attached patch against 2.6.0-test9 adds the
missing two lines from the 2.4 driver to enable this.

So just print a warning and continue.

The #ifdef CONFIG_SMP around the call to schedule_tail was removed a
long time ago for native ia64, but ia32 emulation continues to have a
#ifdef.  We saw a bunch of weird behavior with respect to getpid() on
multithreaded programs (they behave ok on SMP, but break on UP).

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".

I/O errors on "ls" of certain fragmented files found by at least two

- Mucking with the original skb pointers with push/pull around
  the packet quoting was wrong, muching with these pointers could
  cause problems with others using the SKB.

  It was also buggy, it only handled the case where skb->nh.raw was
  ahead of or equal to skb->data

- The fix is to record skb->nh.raw - skb->data and use this as
  a base offset in calls to skb_copy_and_csum_bits().  This is
  what the pre-IPSEC code did.

This fixes IPV6 oopses and packet corruption on 64-bit platforms
when sending UDP port unreachable ICMP messages.

Otherwise, a restarted system call that gets interrupted before

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().
