    >ACPI: Add "acpi.power_nocheck=1" to disable power state check in
power transition:

   >WARNING: at linux-2.6/fs/sysfs/dir.c:463  sysfs_add_one+0x33/0x39()
   >sysfs: duplicate filename 'acpi' can not be created
   >kobject_add_internal failed for acpi with -EEXIST, don't try to register
            things with the same name in the same directory

   In the above commit the "acpi.power_nocheck" module parameter is defined
in drivers/acpi/power.c file. As several module parameters using the same ACPI
prefix are defined in the different files(for example: power_nocheck is
defined in drivers/acpi/power.c,debug_layer/debug_level are defined in
drivers/acpi/debug.c) and there exists another module between them, the
warning message will be printed when using the current generic param code.
(In the function of param_sysfs_init).

   In fact when ACPI is selected, the drivers/acpi/power will also be compiled
as built-in kernel.So this issue can be fixed by the following approach.
   workaround it by adjusting the module link order in drivers/acpi/Makefile.
In such case the module parameter using the same prefix(ACPI) are put together
in the param data section.

   Of course the better solution is to fix it in generic param code related
with sysfs.

Validates predefined ACPI objects that appear in the namespace,
at the time they are evaluated. The argument count and the type of
the returned object are validated. The purpose of this validation
is to detect problems with the BIOS-exposed predefined ACPI objects
before the results are returned to the ACPI-related drivers.

Predicate can be used for an implicit return value.
This change improves the implicit return mechanism to be more
compatible with the MS interpreter.

Fixed two possible memory leaks in the error exit paths of
acpi_ut_update_objerct_reference() and
acpi_ut_walk_package_tree()
These functions are similar in that they use a stack of state objects in
order to eliminate recursion. The stack must be fully deallocated
if an error occurs.
