[git pull request] ACPI & driver patches for 2.6.33-rc1
From: Len Brown
Date: Thu Dec 24 2009 - 01:39:59 EST
Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
This batch fixes the one ACPI regression reported so far in .33.
It includes a few key bug fixes, plus a small arch vs ACPI code re-org.
On the platform-specific-driver side, it adds classmate-laptop,
which I should have sent up before -rc1, plus misc driver updates.
This will update the files shown below.
thanks!

acerhdf: limit modalias matching to supported
BugLink: https://bugs.launchpad.net/ubuntu/+bug/435958
The module alias currently matches any Acer computer but when loaded the
BIOS checks will only succeed on Aspire One models. This causes a invalid
BIOS warning for all other models (seen on Aspire 4810T). This is not
fatal but worries users that see this message. Limiting the moule alias
to models starting with AOA or DOA for Packard Bell.

ACPI: do not select ACPI_DOCK from ATA_ACPI
In March 2008 commit 0ac4a3c2fbbcadc3e96e4dc47d4ae802d66e6f67 ("ACPI: fix
ATA_ACPI build") made CONFIG_ACPI_DOCK be selected by CONFIG_ATA_ACPI because
of a build error when CONFIG_ATA_ACPI=y and CONFIG_ACPI_DOCK=m.
However, in September 2008 commit 898b054f3eec5921320ae8614b5bdd7b07ea5b43
("dock: make dock driver not a module") removed the possibility of having
CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when
CONFIG_ATA_ACPI=y.
This makes the kernel ~5 Kb smaller for people who don't have a dock by
allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y.

sony-laptop: enumerate rfkill devices using SN06
SN06 makes sure we get back a longer buffer which seems to be necessary
going forward as the SNC devices describes more and more devices (or
features more precisely). Moreover SN06 should be called with only the
descriptor offset to make sure we hit the rfkill controlling function
(F124 or F135) with a 0 argument to get a full list of features.

Executing _OSC returns a buffer, which has an acpi object in it.
Don't directly returns the buffer, instead, we return the acpi object's
buffer. This fixes a regression since caller of acpi_run_osc expects
an acpi object's buffer returned.

arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.c: avoid cross-CPU interrupts by using smp_call_function_any()
Presently acpi-cpufreq will perform the MSR read on the first CPU in the
mask. That's inefficient if that CPU differs from the current CPU.
Because we have to perform a cross-CPU call, but we could have run the
rdmsr on the current CPU.
So switch to using the new smp_call_function_any(), which will perform the
call on the current CPU if that CPU is present in the mask (it is).

ACPI: processor: remove _PDC object list from struct acpi_processor
When we call _PDC, we get a handle to the processor, allocate the

_PDC.

else, so let's just get rid of it.

ACPI: processor: change acpi_processor_set_pdc() interface
When calling _PDC, we really only need the handle to the processor
to call the method; we don't look at any other parts of the
struct acpi_processor * given to us.
In the early path, when we walk the namespace, we are given the
handle directly, so just pass it through to acpi_processor_set_pdc()
without stuffing it into a wasteful struct acpi_processor allocated
on the stack each time
This saves 2834 bytes of stack.
Update the interface accordingly.

ACPI: processor: finish unifying arch_acpi_processor_init_pdc()
The only thing arch-specific about calling _PDC is what bits get

There's no need for several levels of indirection to twiddle those
bits. Additionally, since we're just messing around with a buffer,
we can simplify the interface; no need to pass around the entire
struct acpi_processor * just to get at the buffer.

ACPI: processor: unify arch_acpi_processor_init_pdc
The x86 and ia64 implementations of arch_acpi_processor_init_pdc()
are almost exactly the same. The only difference is in what bits
they set in obj_list buffer.
Combine the boilerplate memory management code, and leave the
arch-specific bit twiddling in separate implementations.

ACPI: processor: introduce arch_has_acpi_pdc
arch dependent helper function that tells us if we should attempt to
evaluate _PDC on this machine or not.
The x86 implementation assumes that the CPUs in the machine must be
homogeneous, and that you cannot mix CPUs of different vendors.

ACPI: processor: call _PDC early
We discovered that at least one machine (HP Envy), methods in the DSDT
attempt to call external methods defined in a dynamically loaded SSDT.
Unfortunately, the DSDT methods we are trying to call are part of the
EC initialization, which happens very early, and the the dynamic SSDT
is only loaded when a processor _PDC method runs much later.
This results in namespace lookup errors for the (as of yet) undefined
methods.
Since Windows doesn't have any issues with this machine, we take it
as a hint that they must be evaluating _PDC much earlier than we are.
Thus, the proper thing for Linux to do should be to match the Windows
implementation more closely.
Provide a mechanism to call _PDC before we enable the EC. Doing so loads
the dynamic tables, and allows the EC to be enabled correctly.
The ACPI processor driver will still evaluate _PDC in its .add() method
to cover the hotplug case.

ACPI: disable _OSI(Windows 2009) on Asus K50IJ
Fix a win7 compability issue on Asus K50IJ.
Here is the _BCM method of this laptop:
Method (_BCM, 1, NotSerialized)
{
If (LGreaterEqual (OSFG, OSVT))
{
If (LNotEqual (OSFG, OSW7))
{
Store (One, BCMD)
Store (GCBL (Arg0), Local0)
Subtract (0x0F, Local0, LBTN)
^^^SBRG.EC0.STBR ()
...
}
Else
{
DBGR (0x0B, Zero, Zero, Arg0)
Store (Arg0, LBTN)
^^^SBRG.EC0.STBR ()
...
}
}
}
LBTN is used to store the index of the brightness level in the _BCL.
GCBL is a method that convert the percentage value to the index value.
If _OSI(Windows 2009) is not disabled, LBTN is stored a percentage
value which is surely beyond the end of _BCL package.

tc1100-wmi - add error handling for device registration
Any of the platform API functions can fail; driver should be prepared
to handle such failures. Also:
- changed to platform_driver_probe() since the device is created
right there with the driver;
- added __devexit annotation to remove method;
- fixed memory leak on module unload - named platform_device_del() is not
enough to free platform device, need platform_device_unregister().
