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].

_OSI("Linux") is like _OS("Linux"), it is ill-defined and
virtually no BIOS vendors test interaction with it.
As a result, it can do more damage than good because
it causes the BIOS to follow un-tested paths.
Recently, several machines have turned up that erroneously
test this string in a way which causes them to _not_ test other
compatibility strings, including the ZI9 and Toshiba.
So it appears that this bad code has made it into
a BIOS vendor's reference BIOS.
Linux has no choice but to stop advertising compatibility
with _OSI string "Linux" - as there are an unbounded
number of possible incompatibilities going forward.
But some BIOSes have already shipped which do use it
for things like conditionally re-enabling video on resume
from S3. (Too bad they didn't do that unconditionally)
Add special case code for _OSI(Linux)
Squawk to dmesg if _OSI(Linux) is requested
Add DMI list both to enable and disable _OSI(Linux)
But for now, keep the default enabled via
#define OSI_LINUX_ENABLED.

The boot option "acpi_osi=" has always disabled Linux _OSI support,
thus disabling all OS Interface strings which are advertised
by Linux to the BIOS.
Now...
acpi_osi="string" adds the interface string, and
acpi_osi="!string" invalidates the pre-defined interface string
eg. acpi_osi="!Windows 2006"
would disable Linux's claim of Vista compatibility.

This reverts commit c0d127b569.
These changes to AML locking were made to allow
Notify handlers to be called on the stack
and not deadlock. However, that scheme turns
out to be flawed and was reverted by the previous commit,
so this commit restores the locking to it previous design.

ACPI AML supports "serialized" methods which are protected
by an implicit mutex. The mutex is re-entrant for that AML thread
to allow recursion.
However, Linux implements notify() by creating a new AML thread.
So for systems where notify() re-enters a serialized method,
deadlock results.
The fix is to use the Linux thread_id as the key to allowing
re-entrancy, not the AML thread pointer.
