Update all module headers with 2010 copyright. Also includes the
automated cleanup, this is the first time it has been run on the
test suite source, so there are quite a few changes (removal of
extra spaces at the end-of-line, etc.)
Add 2010 copyright to all module headers and signons, including the Linux
header. This affects virtually every file in the ACPICA core subsystem,
iASL compiler, and all utilities.
Added several new options for the gcc-4 generation, and updated the source
accordingly. This includes some code restructuring to eliminate unreachable
code, elimination of some gotos, elimination of unused return values, and
some additional casting.
This change moves the check for a valid Thread ID structure up a few lines
to insure that the check is made before the structure is actually used.

This change will automatically remove embedded and trailing NULL package
elements from returned package objects that are defined to containe a
variable number of sub-packages. The driver is then presented with
a package with no null elements to deal with. ACPICA BZ 819.
This change enables the execution of _REG methods that appear in the
same scope as the module-level code, in resonse to an operation region
declaration within the module-level code.
Repair mechanism was considered too wordy. Now, messages are only
unconditionally emitted if the return object cannot be repaired.
Existing messages for successful repairs were converted to
ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827.
Fixes a problem where mutex errors can occur when running a _REG method
that is in the same scope as a method-defined operation region or an
operation region under a module-level IF block. This is rare, so the
problem has not been seen before. ACPICA BZ 826. Lin Ming, Bob Moore.
This change enhances the automatic repairs/conversions for predefined
name return values to make Integers, Strings, and Buffers fully
interchangeable. Also, a Buffer can be converted to a Package of
Integers if necessary. The nsrepair.c module was completely restructured.
Lin Ming, Bob Moore.
This option specifies the value used to initialize buffers used to
simulate operation regions. Default is zero. Useful for debugging
problems that depend on a specific initial value for a region or
field.
This fixes a regression introduced in version 20091112. A .src
intermediate file is always created during compilation and should
be deleted at compiler exit.
The expected return value for both names is a Buffer of 5 DWORDS.
This repair fixes two possible problems (both seen in the field):
A package of integers is returned, or a buffer of BYTEs is
returned.
An object can be leaked for each block of executed module-level
code if the interpreter slack mode is enabled. The change
deletes any implicitly returned object in this case.
This change will repair (by sorting) packages returned by _ALR,
_PSS, and _TSS. Drivers can now assume that the packages are
correctly sorted. Adds one new file, namespace/nsrepair2.c
ACPICA BZ 784. Lin Ming, Bob Moore.
Adds a new remark for a Package() declaration if an initializer
list exists, but is shorter than the declared length of the package.
Although technically legal, this is probably a coding error and
it is seen in the field. ACPICA BZ 815. Lin Ming, Bob Moore.
The existing interface only has a pre-order callback. This change
adds an additional parameter for a post-order callback which will
be more useful for bus scans. ACPICA BZ 779. Lin Ming.
This message happens when the package element list is longer than
the declared length of the package. Changed to an info message
because this condition is not actually an error. It is caused by
the BIOS attempting to truncate the package on the fly by adjusting
the package element count at the start of the package definition.
Ensure that memory mappings created for operation regions do
not cross page boundaries. Crossing a page boundary while mapping
regions can cause warnings if the pages have different attributes.
Such regions are probably BIOS bugs, and this is the workaround.
Linux BZ 14445. Lin Ming.
This change correctly implements the Switch operator with a surrounding
While(1) so that the Break statement works as expected.
ACPICA BZ 461. Lin Ming.
Since the object was successfully repaired, a Warning is too severe.
Reduced to Info for now. We may eventually change these messages
to debug-only. ACPICA BZ 812.
