[PATCH v3 0/3] Prepare for running ACPI on !x86 and !ia64

Some of the ACPI code is arch-dependent and make the code can't be
compiled on !x86 or !ia64, the first two patches just do some rework
on the idle_boot_override and _PDC related stuff to make the ACPI
code more arch-independent.

The third patch just introduce map_gic_id() for ACPI processor core
followed the ACPI 5.0 spec.

I have compiled the kernel successfully after appling this patch set
on x86 and ia64.

Changes for v3:
Fix the issues pointed out by Lan Tianyu and and the Reviewed-by for
first patch.

Changes for v2:
a) add #if defined(CONFIG_X86) || defined(CONFIG_IA64) for
   idle_boot_override related code;
b) Rebased on 3.14-rc1.

Changes since the RFC version:
a) Remove the RFC tag;
b) Move idle_boot_override out of the arch directory suggested
   by Alan;
c) Make these 3 patches as a separate patch set since there are
   not not related to the ARM/ARM64 platform.

Hanjun Guo (3):
  ACPI / idle: Make idle_boot_override depend on x86 and ia64
  ACPI / processor_core: Rework _PDC related stuff to make it more
  ACPI: Introduce map_gic_id() to get apic id from MADT or _MAT method
