Subject[git pull request] ACPICA patches for Linux-2.6.33-merge
Hi Linus,

please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git acpica

This updates Linux to ACPICA v20091112 from v20090903.
Later during the v2.6.33 cycle, I may also cherry pick
a few debug tweaks I'm expecting in a subsequent ACPICA release.

This will update the files shown below.

thanks!

ps. individual patches are available on linux-acpi@vger.kernel.org
and a consolidated plain patch is available here:

acpi_ut_create_integer_object. This function (when deployed) should
simplify some of the object creation code. ACPICA BZ 823.

ACPICA: Add repair for predefined methods that must return sorted lists

This change will repair (by sorting) packages returned by _ALR,
_PSS, and _TSS. Drivers can now assume that the packages are
correctly sorted. Adds one new file, nsrepair2.c.

ACPICA: Add post-order callback to acpi_walk_namespace

The existing interface only has a pre-order callback. This change
adds an additional parameter for a post-order callback which will
be more useful for bus scans. ACPICA BZ 779.

Also update the external calls to acpi_walk_namespace.

Author: Bob Moore <robert.moore@intel.com>
Date: Thu Nov 12 09:31:50 2009 +0800

ACPICA: Change package length error message to an info message

This message happens when the package element list is longer than
the declared length of the package. Changed to an info message
because this condition is not actually an error. It is caused by
the BIOS attempting to truncate the package on the fly by adjusting
the package element count at the start of the package definition.

ACPICA: Reduce severity of predefined repair messages, Warning to Info

Since the object was successfully repaired, a Warning is too
severe. Reduced to Info for now. We may eventually change these
messages to debug-only. ACPICA BZ 812.

ACPICA: Remove possibility of executing _REG methods twice

If a custom address space handler is installed by the host
before the "initialize operation regions" phase of the ACPICA
initialization, any _REG methods for that address space could
be executed twice. This change fixes the problem.

ACPICA: Add repair for bad _MAT buffers

_MAT can inadvertently return an Integer instead of a Buffer
if the return value has been read from a Field whose width is
less than or equal to the global integer width (32 or 64 bits).
