This is the remaining misc drivers/ part of the big kfree cleanup patch.

drivers/.

01a527ec7c [PATCH] drivers/acpi: fix-up schedule_timeout() usage
Use schedule_timeout_interruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size.  Also use
msecs_to_jiffies() instead of direct HZ division to avoid rounding errors.

4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

0b0acbec1b [PATCH] memory hotplug: move section_mem_map alloc to sparse.c
This basically keeps up from having to extern __kmalloc_section_memmap().

The vaddr_in_vmalloc_area() helper could go in a vmalloc header, but that
header gets hard to work with, because it needs some arch-specific macros.
Just stick it in here for now, instead of creating another header.

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.

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.

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.

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.
