acpi/cst: Keep parsing rest of the GAS, even if the mwait hint is wrong.
The rest part of GAS contains useful bus mastering information.

x86_64: Take advantage of ACPI/CPU specific C-state mapping
If BIOS maps shallow ACPI C-state (<C3) to deep CPU specific C-state
(>=C3), it implies no bus mastering operations are needed before

The native C-state on Intel CPUs is entered using monitor/mwait w/ the
help from mwait hint (eax) and extension (ecx, break upon i
acpi/cstate/x86_64: Implement native C-state support for Intel CPUs
The native C-state on Intel CPUs is entered using monitor/mwait w/ the
help from mwait hint (eax) and extension (ecx, break upon interrupt).
We still need to keep an eye on native C1 state. Currently C1 state
only uses "sti;halt".

Add comment we still need to filter Intel's "C1 I/O then halt". It
probably won't be problem, since the related bit is not set i

Add comment we still need to filter Intel's "C1 I/O then halt". It
probably won't be problem, since the related bit is not set in _OSC

acpi/cstate: Rework preamble operation for entering C-state
- Save preamble operation in C-state struct, instead of choosing
preamble operation at run time
- Add machine depend C-state setup code
acpi/cstate: Rework preamble operation for entering C-state
- Save preamble operation in C-state struct, instead of choosing
preamble operation at run time
- Add machine depend C-state setup code to optimize out certain
preamble operation for various CPU vendors
- Fix up generic preamble operation setup according to ACPI spec
