Fix the IDE hang people see with 2.5.65-bk

From Dominik Brodowski <linux@brodo.de>

PC9800 uses the ISAPnP protocol but on CBUS not ISA bus. The
current patch is below. I'm wondering if there is a cleaner way we
should do this ?

So its now two options

I missed the CREDITS change before

[From Osamu Tomita]

This fixes one of the long standing IDE hangs on SMP. If you
get an error we disable the IRQ, unfortunately we may be in
the IRQ handler

This change gets us back working but does introduce a small
potential race I need to investigate further and fix up in
a nicer fashion.

IDE should do error handling in a seperate context (as SCSI
does) but not for 2.6.

both ways, but anal compilers will warn about using identifiers that
have never been defined in preprocessor expression statements.

recalc_signpending() needs tsk->sighand->siglock.

It seems pretty pointless and people do complain about it occasionally.

Additional work to make syscalls return longs.

From: "Randy.Dunlap" <randy.dunlap@verizon.net>

Fix up various syscalls to return longs, as x86_64 and ia64 (at least)
require.

I got a .exit.text error in 2.5.65.

The problem is that in sound/oss/awe_wave.c the __init function
_attach_awe calls the __exit function awe_release_region.

The following patch that removes the __exit from awe_release_region
fixes it.
