[PATCH v2 0/6] Remove the duplicated _MAT evaluation and simplify _acpi_map_lsapic()

From: Hanjun Guo
Date: Sun Sep 01 2013 - 23:59:16 EST


v1->v2: Return specific error value instead of just return -1, and
correct some grammar mistake in changelog.

For cpu hot add, evaluate _MAT or parse MADT will did twice to get
APIC id:
acpi_processor_add()
acpi_processor_get_info()
acpi_get_cpuid() will evaluate _MAT or parse MADT;
acpi_processor_hotadd_init()
acpi_map_lsapic() will evaluate _MAT again;

This patch set introduces apic_id in struct processor to save parsed
APIC id, and use it to remove the duplicated _MAT evaluation.

Further more, the new logical cpu number will be generated in
acpi_register_lapic(), this can be returned to remove the cpumask
allocation and operation to simplify _acpi_map_lsapic().

There are also some cleanups for the ACPI processor dirver code.

ACPI / processor: remove unnecessary if (!pr) check
ACPI / processor: Remove outdated comments

ACPI / processor: Introduce apic_id in struct processor to save
parsed APIC id
