ACPI: allow C3 > 1000usec
Do for C3 what the previous patch did for C2.
The C2 patch was in response to a highly visible
and multiply reported C-state/turbo failure,
while this change has no bug report in-hand.
This will enable C3 in Linux on systems where BIOS
overstates C3 latency in _CST. It will also enable
future systems which may actually have C3 > 1000usec.
Linux has always ignored ACPI BIOS C3 with exit latency > 1000 usec,
and the ACPI spec is clear that is correct FADT-supplied C3.
However, the ACPI spec explicitly states that _CST-supplied C-states
have no latency limits.
So move the 1000usec C3 test out of the code shared
by FADT and _CST code-paths, and into the FADT-specific path.

ACPI: enable C2 and Turbo-mode on Nehalem notebooks on A/C
Linux has always ignored ACPI BIOS C2 with exit latency > 100 usec,
and the ACPI spec is clear that is correct FADT-supplied C2.
However, the ACPI spec explicitly states that _CST-supplied C-states
have no latency limits.
So move the 100usec C2 test out of the code shared
by FADT and _CST code-paths, and into the FADT-specific path.
This bug has not been visible until Nehalem, which advertises
a CPU-C2 worst case exit latency on servers of 205usec.
That (incorrect) figure is being used by BIOS writers
on mobile Nehalem systems for the AC configuration.
Thus, Linux ignores C2 leaving just C1, which is
saves less power, and also impacts performance
by preventing the use of turbo mode.

ACPI: processor: restrict early _PDC to opt-in platforms
Commit 78f1699 (ACPI: processor: call _PDC early) blindly walks
the namespace and calls _PDC on every processor object it finds.
This change may cause issues on platforms that declare dummy
values for SSDTs on non-present processors (disabled in MADT).
When we call _PDC and dynamically attempt to execute the AML
Load() op on these dummy SSDTs, there's no telling what might
happen.
Rather than finding every platform that has bogus SSDTs, restrict
early _PDC calls to platforms that are known to need early
evaluation of _PDC.
This is a minimal, temporary fix (given the context of the
current release cycle). A real solution of checking the MADT for
non-present processors will be written for the next merge window.

ACPI: Fix section mismatch error for acpi_early_processor_set_pdc()
Alex Chiang introduced acpi_early_processor_set_pdc() in commit:
ACPI: processor: call _PDC early
78f1699659963fff97975df44db6d5dbe7218e55
But this results in a section mismatch:
WARNING: drivers/acpi/acpi.o(.text+0xa9c1): Section mismatch in reference from the
function acpi_early_processor_set_pdc() to the variable .cpuinit.data:processor_idle_dmi_table
The function acpi_early_processor_set_pdc() references
the variable __cpuinitdata processor_idle_dmi_table.
This is often because acpi_early_processor_set_pdc lacks a __cpuinitdata
annotation or the annotation of processor_idle_dmi_table is wrong.
The only caller of acpi_early_processor_set_pdc() is acpi_bus_init() which
is an "__init" function. So the correct fix here is to mark
acpi_early_processor_set_pdc() "__init" too.

eeepc-laptop: disable cpu speed control on EeePC 701
The EeePC 4G ("701") implements CFVS, but it is not supported by the
pre-installed OS, and the original option to change it in the BIOS
setup screen was removed in later versions. Judging by the lack of
"Super Hybrid Engine" on Asus product pages, this applies to all "701"
models (4G/4G Surf/2G Surf).
So Asus made a deliberate decision not to support it on this model.
We have several reports that using it can cause the system to hang [1].
That said, it does not happen all the time. Some users do not
experience it at all (and apparently wish to continue "right-clocking").
Check for the EeePC 701 using DMI. If met, then disable writes to the
"cpufv" sysfs attribute and log an explanatory message.
Add a "cpufv_disabled" attribute which allow users to override this
policy. Writing to this attribute will log a second message.
The sysfs attribute is more useful than a module option, because it
makes it easier for userspace scripts to provide consistent behaviour
(according to user configuration), regardless of whether the kernel
includes this change.

commit 8bd108d adds preemption point after each opcode parse, then
a sleeping function called from invalid context bug was founded
during suspend/resume stage. this was fixed in commit abe1dfa by
don't cond_resched when irq_disabled. But recent commit 138d156 changes
the behaviour to don't cond_resched when in_atomic. This makes the
sleeping function called from invalid context bug happen again, which
is reported in http://lkml.org/lkml/2009/12/1/371.

This messes up the ACPI video backlight control.

With this patch applied, only the FIRST ACPI video bus device

1. When met a bogus BIOS, the return value of cpu number maybe is
