ACPI patches for 2.6.22 - part 4

Hi Linus,

please pull from:

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

This fixes three regressions, two small ones from within 2.6.22, and a boot hang due to a race condition originating in 2.6.20.

It will update the files shown below.

thanks!

-Len

ACPI: fix 2.6.20 SMP boot regression

Always disable/enable interrupts in the acpi idle routine, even in the error path.

This is required as the 2.6.20 change in git commit d331e739f5ad2aaa9... "Fix interrupt race in idle callback" expects the idle handler to enable interrupt before returning.

There was a case in acpi idle routine, in which interrupt was not being enabled before return, which caused the system to hang at bootup, while enabling C-states on an SMP system.

The signature of the hang was that "processor.nocst" was required to enable boot.

ACPICA: fix error path in new external package objects as method arguments

In the routine acpi_ut_create_package_object(), if the ACPI_ALLOCATE_ZEROED() fails then ACPI_FREE(package_desc) is called as part of the cleanup. This should instead be acpi_ut_remove_reference(package_desc) in order to remove the reference acquired from acpi_ut_create_internal_object() [see the routine acpi_ut_create_buffer_object() as an example of proper functionality].

ACPI: gracefully print null trip-point device

if acpi_bus_get_device() returns NULL, print nothing instead of "<NUL" in /proc/acpi/thermal_zone/*/trip_points
