Peter Chubb 51b190b304 [PATCH] `unaligned access' in acpi get_root_bridge_busnr()
In drivers/acpi/glue.c the address of an integer is cast to the address of
an unsigned long.  This breaks on systems where a long is larger than an
int --- for a start the int can be misaligned; for a second the assignment
through the pointer will overwrite part of the next variable.

Pavel Machek b01d8684e9 [PATCH] remove ACPI S4bios support
Remove S4BIOS support.  It is pretty useless, and only ever worked for _me_
once.  (I do not think anyone else ever tried it).  It was in feature-removal
for a long time, and it should have been removed before.

This makes ACPI_BLACKLIST_YEAR be consistently defined when ACPI is

bogus -Wundef warnings on ia64.

Robert Moore aff8c2777d [ACPI] ACPICA 20050902
Fixed a problem with the internal Owner ID allocation and
deallocation mechanisms for control method execution and
recursive method invocation.  This should eliminate the
OWNER_ID_LIMIT exceptions and "Invalid OwnerId" messages
seen on some systems.  Recursive method invocation depth
is currently limited to 255.  (Alexey Starikovskiy)

http://bugzilla.kernel.org/show_bug.cgi?id=4892

Completely eliminated all vestiges of support for the
"module-level executable code" until this support is
fully implemented and debugged.  This should eliminate the
NO_RETURN_VALUE exceptions seen during table load on some
systems that invoke this support.

http://bugzilla.kernel.org/show_bug.cgi?id=5162

Fixed a problem within the resource manager code where
the transaction flags for a 64-bit address descriptor were
handled incorrectly in the type-specific flag byte.

Consolidated duplicate code within the address descriptor
resource manager code, reducing overall subsystem code size.

Bob Moore a18ecf413c [ACPI] ACPICA 20050815
Implemented a full bytewise compare to determine if a table load
request is attempting to load a duplicate table. The compare is
performed if the table signatures and table lengths match. This
will allow different tables with the same OEM Table ID and
revision to be loaded.

Although the BIOS is technically violating the ACPI spec when
this happens -- it does happen -- so Linux must handle it.

Eric W. Biederman 8dbddf1782 [PATCH] acpi_shutdown: Only prepare for power off on power_off
When acpi_sleep_prepare was moved into a shutdown method we
started calling it for all shutdowns.

It appears this triggers some systems to power off on reboot.

Avoid this by only calling acpi_sleep_prepare if we are going to power
off the system.

Len Brown 07fefe4ca9 [ACPI] remove "default m" from acpi/Kconfig
Andi Kleen suggested it was unconventional for us to "default m"
on ACPI modules -- even though they are expected to be deployed
as modules.  But as "default n" would likely result in some
users building nonsense kernels, we compromise to "default y".

Distros are expected to continue to use =m in their configs.

silently assumes the segment to be zero in this case,
so glue.c shouldn't complain either.
