Subject[PATCH 0/5] ACPI: Add _OST support for ACPI hotplug
Date
This series of patches supports ACPI _OST (OSPM Status Indication)
method for ACPI-based CPU and memory hotplug operations. After
ACPI-based hotplug operation completed, OSPM calls _OST to convey
the completion status to ACPI firmware. If _OST is not present,
this change has no effect on the platform.

The _OST definition can be found in section 6.3.5 of ACPI 5.0 spec.
The HPPF spec below also describes hotplug flows with _OST.

DIG64 Hot-Plug & Partitioning Flow (HPPF) Specification R1.0
http://www.dig64.org/home/DIG64_HPPF_R1_0.pdf

The change was tested by overriding DSDT with fake _OST methods.
