(ACPI: Processor native C-states using MWAIT)
started passing C2C3_FFH to _PDC to tell the BIOS
that Linux supports MWAIT for deep C-states.
However, we should first double check with the hardware
that it actually supports MWAIT before potentially exposing
a BIOS bug of an MWAIT _CST on HW that doesn't support MWAIT.

ACPI: Set _PSD ACPI_PDC_SMP_T_SWCOORD2008-02-02T07:22:43ZZhao Yakui2008-01-28T05:53:21Zurn:sha1:3abbd337c60591305cbfeb984ff2922c175be37f
The ACPI_PDC_SMP_T_SWCOORD bit is set by and OS that is capable of
native ACPI throttling software coordination for mutli-processors
using the _TSD information.

x86: convert cpuinfo_x86 array to a per_cpu array2007-10-19T18:35:04ZMike Travis2007-10-19T18:35:04Zurn:sha1:92cb7612aee39642d109b8d935ad265e602c0563
cpu_data is currently an array defined using NR_CPUS. This means that
we overallocate since we will rarely really use maximum configured cpus.
When NR_CPU count is raised to 4096 the size of cpu_data becomes
3,145,728 bytes.
These changes were adopted from the sparc64 (and ia64) code. An
additional field was added to cpuinfo_x86 to be a non-ambiguous cpu
index. This corresponds to the index into a cpumask_t as well as the
per_cpu index. It's used in various places like show_cpuinfo().
cpu_data is defined to be the boot_cpu_data structure for the NON-SMP
case.
