Subject: [GIT PATCH] ACPI patches for 2.6.22 - part 3
Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
This batch fixes two places where Linux currently fails to load tables
of the format that we expect OEM's to soon ship -- OEMx and
packages-as-method-arguments for _DSM. In both cases the changed
code has no effect on systems without those needs.
The acpi_osi= boot parameter is expanded and invoked automatically
via DMI for some systems that need it. We stop short here of changing
the default to acpi_osi=Linux -- that waits for 2.6.23.
The Thinkpad commit is for a 2.6.22 regression,
as is the section mis-match build fix.
This will update the files shown below.
thanks!
-Len

ACPICA: Support for external package objects as method arguments
Implemented support to allow Package objects to be passed as
method arguments to the acpi_evaluate_object interface. Previously,
this would return an AE_NOT_IMPLEMENTED exception.

ACPI: Section mismatch ... acpi_map_pxm_to_node
Last of the "Section mismatch" errors from ia64 builds! acpi_map_pxm_to_node()
is defined with attribute __cpuinit, but is called by "normal" kernel functions
acpi_getnode() and acpi_map_cpu2node().
Commit f363d16fbb9374c0bd7f2757d412c287169094c9 moved the data structures on
which this routine operates from __cpuinitdata to regular memory, so this
routine can also move out of init space.

ACPI: thinkpad-acpi: do not use named sysfs groups
The initial version of the thinkpad-acpi sysfs interface (not yet released
in any stable mainline kernel) made liberal use of named sysfs groups, in
order to get the attributes more organized.
This proved to be a really bad design decision. Maybe if attribute groups
were as flexible as a real directory, and if binary attributes were not
second-class citizens, the idea of subdirs and named groups would not have
been so bad.
This patch makes all the thinkpad-acpi sysfs groups anonymous (thus
removing the subdirs), adds the former group names as a prefix (so that
hotkey/enable becomes hotkey_enable for example), and updates the
documentation.
These changes will make the thinkpad-acpi sysfs ABI a lot easier to
maintain.

ACPI: Make _OSI(Linux) a special case
_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.

commit ae00d812436dc968f4a5dea7757b6a94910b6dc4

ACPI: extend "acpi_osi=" boot option
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.
