[BNX2]: Fix netdev watchdog on 5708.
There's a bug in the driver that only initializes half of the context
memory on the 5708. Surprisingly, this works most of the time except
for some occasional netdev watchdogs when sending a lot of 64-byte
packets. The fix is to add the missing code to initialize the 2nd
halves of all context memory.

Restrict clearing TIF_SIGPENDING

libata: always use polling SETXFER
Several people have reported LITE-ON LTR-48246S detection failed
because SETXFER fails. It seems the device raises IRQ too early after
SETXFER. This is controller independent. The same problem has been
reported for different controllers.
So, now we have pata_via where the controller raises IRQ before it's
ready after SETXFER and a device which does similar thing. This patch
makes libata always execute SETXFER via polling. As this only happens
during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is
also moved from issue hot path to ata_dev_set_xfermode() - the only
place where SETXFER can be issued.
Note that ATA_TFLAG_POLLING applies only to drivers which implement
SFF TF interface and use libata HSM. More advanced controllers ignore
the flag. This doesn't matter for this fix as SFF TF controllers are
the problematic ones.

[AF_UNIX]: Fix datagram connect race causing an OOPS.
Based upon an excellent bug report and initial patch by
Frederik Deweerdt.
The UNIX datagram connect code blindly dereferences other->sk_socket
via the call down to the security_unix_may_send() function.
Without locking 'other' that pointer can go NULL via unix_release_sock()
which does sock_orphan() which also marks the socket SOCK_DEAD.
So we have to lock both 'sk' and 'other' yet avoid all kinds of
potential deadlocks (connect to self is OK for datagram sockets and it
is possible for two datagram sockets to perform a simultaneous connect
to each other). So what we do is have a "double lock" function similar
to how we handle this situation in other areas of the kernel. We take
the lock of the socket pointer with the smallest address first in
order to avoid ABBA style deadlocks.
Once we have them both locked, we check to see if SOCK_DEAD is set
for 'other' and if so, drop everything and retry the lookup.

[POWERPC] Fix zImage.coff generation for 32-bit pmac
Commit 9da82a6dee9db4cd5ae7a74ab4f51afb52b6efb9 inadvertently
removed the platform override for zImage.coff to be generated
with pmaccoff. Rather than add a special makefile rule,
change the platform for which the wrapper platform uses
the special rules.

[POWERPC] Compare irq numbers with NO_IRQ not IRQ_NONE
There is a thinko in the irq code, it uses IRQ_NONE to indicate no irq,
whereas it should be using NO_IRQ. IRQ_NONE is returned from irq
handlers to say "not handled".
As it happens they currently have the same value (0), so this is just for
future proof-ness.

[POWERPC] Don't use HOSTCFLAGS in BOOTCFLAGS
In the bootwrapper code for powerpc, we include HOSTCFLAGS into the
BOOTCFLAGS used for building the zImage wrapper code. Since the
wrapper code is not host code, this makes no sense. This patch
removes the use of HOSTCFLAGS here, instead including directly into
BOOTCFLAGS those flags from the normal kernel CFLAGS which also make
sense in the bootwrapper code.
In particular, this makes the bootwrapper use -msoft-float, preventing
the compiler from generating floating point instructions. Previously,
under some circumstances the compiler could generate floating point
instructions in the bootwrapper which would cause exceptions on
embedded CPUS which don't have floating point support.

This zImage is really just the stripped vmlinux, but it means that there

I think we have a subtle race on ppc64 with the tlb batching. The
common code expects tlb_flush() to actually flush any pending TLB
batch. It does that because it delays all page freeing until after
tlb_flush() is called, in order to ensure no stale reference to
those pages exist in any TLB, thus causing potential access to
the freed pages.
However, our tlb_flush only triggers the RCU for freeing page
table pages, it does not currently trigger a flush of a pending
TLB/hash batch, which is, I think, an error. This fixes it.

[POWERPC] Fix compiler/assembler flags for Ebony platform boot files
The recent addition of assembler flags for 44x.c and ebony.c in the
bootwrapper to make them compile on certain toolchains was not correct
and could break other platforms. This patch switches to using a
compiler flag instead, which implies the appropriate assembler flag,
and also stops the compiler itself generating instructions which are
invalid for the platform in question.

[POWERPC] Fix ppc32 single-stepping out of syscalls
The ppc32 kernel didn't properly set/clear the TIF_SINGLESTEP
flag, causing return from syscalls to not SIGTRAP, thus executing
one more instruction before stopping again.
This fixes it. The ptrace code is a bit of a mess, and is overdue
for at least a -proper- 32/64 bits split and possibly more cleanups
but this minimum fix should be ok for 2.6.22

[SCSI] aacraid: fix shutdown handler to also disable interrupts.
Moves quiesce, thread and interrupt shutdown into aacraid drivers'
.shutdown handler. This fix to the aac_shutdown handler will remove the
superfluous reset of the adapter during a (clean) kexec.
This fix may mitigate the active investigation 'kexec and aacraid
broken' but it is unlikely to affect the root cause (issue likely
present in both kexec and kdump). This patch reduces the chance the
problem will occur with a kexec. The fix for root cause is currently
expected to be the minimum value check to the aacraid.startup_timeout
driver variable after an adapter reset within aacraid_commit_reset.patch
submitted on 05/22/2007 and awaiting testing by Yinghai to confirm.
