Here's the patchlist:

ACPICA: Cleanup macro definition file
ACPICA: Copy dynamically loaded tables to local buffer
ACPICA: Fix warning for 64-bit build
ACPICA: Add check for invalid handle in acpi_get_object_info
ACPICA: Fix memory leak when deleting thermal/processor objects
ACPICA: Allow same ACPI table to be loaded/unloaded more than once
ACPICA: Fix possible memory leak in Unload() operator
ACPICA: Return method arg count from acpi_get_object_info
ACPICA: Fix wrong resource descriptor length for 64-bit build
ACPICA: Fix table compare code, length then data
ACPICA: Update version to 20080701
ACPICA: Return status from global init function
ACPICA: Add function to decode reference obj types to strings
ACPICA: Improve object conversion error messages
ACPICA: x2APIC support: changes for MADT and SRAT ACPI tables
ACPICA: Add function to dereference returned reference objects
ACPICA: Additional error checking for pathname utilities
ACPICA: Update version to 20080729


Most of these are bug fixes, new stuff would be the following:

ACPICA: Cleanup macro definition file
ACPICA: Return method arg count from acpi_get_object_info
ACPICA: Add function to decode reference obj types to strings
ACPICA: Improve object conversion error messages
ACPICA: x2APIC support: changes for MADT and SRAT ACPI tables


Leaving these as the bug fixes that should be integrated:

ACPICA: Copy dynamically loaded tables to local buffer
ACPICA: Fix warning for 64-bit build
ACPICA: Add check for invalid handle in acpi_get_object_info
ACPICA: Fix memory leak when deleting thermal/processor objects
ACPICA: Allow same ACPI table to be loaded/unloaded more than once
ACPICA: Fix possible memory leak in Unload() operator
ACPICA: Fix wrong resource descriptor length for 64-bit build
ACPICA: Fix table compare code, length then data
ACPICA: Return status from global init function
ACPICA: Add function to dereference returned reference objects
ACPICA: Additional error checking for pathname utilities


I'm not sure what you should do with the version numbers, I don't think
you should advertise a certain version of ACPICA until it has been
*fully* integrated.

ACPICA: Update version to 20080701
ACPICA: Update version to 20080729
