Fixed a problem with the internal Owner ID allocation and
deallocation mechanisms for control method execution and
recursive method invocation. This should eliminate the
OWNER_ID_LIMIT exceptions and "Invalid OwnerId" messages
seen on some systems. Recursive method invocation depth
is currently limited to 255. (Alexey Starikovskiy)

Completely eliminated all vestiges of support for the
"module-level executable code" until this support is
fully implemented and debugged. This should eliminate the
NO_RETURN_VALUE exceptions seen during table load on some
systems that invoke this support.

Fixed a problem within the resource manager code where
the transaction flags for a 64-bit address descriptor were
handled incorrectly in the type-specific flag byte.
Consolidated duplicate code within the address descriptor
resource manager code, reducing overall subsystem code size.

Implemented a full bytewise compare to determine if a table load
request is attempting to load a duplicate table. The compare is
performed if the table signatures and table lengths match. This
will allow different tables with the same OEM Table ID and
revision to be loaded.
Although the BIOS is technically violating the ACPI spec when
this happens -- it does happen -- so Linux must handle it.

When acpi_sleep_prepare was moved into a shutdown method we
started calling it for all shutdowns.
It appears this triggers some systems to power off on reboot.
Avoid this by only calling acpi_sleep_prepare if we are going to power
off the system.

Andi Kleen suggested it was unconventional for us to "default m"
on ACPI modules -- even though they are expected to be deployed
as modules. But as "default n" would likely result in some
users building nonsense kernels, we compromise to "default y".
Distros are expected to continue to use =m in their configs.

Distros are shipping modules we had marked EXPERIMENTAL,
so clearly it has lost some meaning.
Delete that dependency for shipping modules, retaining
it only for ACPI_HOTKEY and ACPI_CONTAINER to emphasize
that they lack testing on real hardware.

was to choose the destination version of the file

If there are devices that use interrupts over a suspend event, ACPI must
restore the PCI interrupt links on resume. Anything else breaks any
device that hasn't been converted to the new (dubious) PM rules.
Drivers that need the irq free/re-aquire sequence can be done one by one
independently of this one.
Implemented support to ignore an attempt to install/load
a particular ACPI table more than once. Apparently there
exists BIOS code that repeatedly attempts to load the same
SSDT upon certain events. Thanks to Venkatesh Pallipadi.
Restructured the main interface to the AML parser in
order to correctly handle all exceptional conditions. This
will prevent leakage of the OwnerId resource and should
eliminate the AE_OWNER_ID_LIMIT exceptions seen on some
machines. Thanks to Alexey Starikovskiy.
Support for "module level code" has been disabled in this
version due to a number of issues that have appeared
on various machines. The support can be enabled by
defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem
compilation. When the issues are fully resolved, the code
will be enabled by default again.
Modified the internal functions for debug print support
to define the FunctionName parameter as a (const char *)
for compatibility with compiler built-in macros such as
__FUNCTION__, etc.
Linted the entire ACPICA source tree for both 32-bit
and 64-bit.
