[PATCH v3 0/7] minor cleanups for ACPI processor driver

[Hanjun Guo]

This patch set is some minor cleanups for ACPI processor driver
to address the comments which raised by Rafael in ARM64 ACPI core
patches.

Boris and Konrad already reviewed the XEN/ACPI part, they seems are
ok with the changes for XEN [1] [2].

Sudeep, I didn't change the (int)phys_id < 0 to phys_id == PHYS_CPUID_INVALID
as they have the same effects and Rafael prefer the previous one
as he mentioned in ACPI core patch set comments, and PHYS_CPUID_INVALID
is still needed for typedef phys_cpuid_t in ACPI core, so if you are
not ok with it, please let me know.

v3:
 - Reorder the patches to let "Introduce invalid_logical_cpuid()"
   as the first one to avoid raising confusions.
 - Replace "return invalid_logical_cpuid(cpuid) ? false : true;"
   as "return !invalid_logical_cpuid(cpuid);"
 - Some updates to the patch subject and changelog
 - Rebase on top of 4.1-rc3

v2:
 - rebased on top of 4.1-rc2
