From: Rui Wang

A set of patches fixing bugs found while testing IOAPIC hotplug.

Regards,
Rui

Changelog:

Changes from v3 to v4:
* Rebased on top of 4.8-rc2 and re-tested it.
* Added the missing 'Acked-by: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>' in 0002.
* Sent to x86@xxxxxxxxxx for review as suggested by Rafael.

Changes from v2 to v3:
* Rebased on top of 4.8-rc1 per Bjorn & Rafael.
* Improved the commit message of 0003, w/ clearer explanation.

Changes from v1 to v2:
* Split the first patch into two as advised by Bjorn: "would be nicer if
the interface change and header file munging were in a separate patch so
they wouldn't obscure the meat of the change, i.e., the addition of calls
to acpi_ioapic_add()."
* Removed acpi_ioapic_add() as an exported symbol.
* Fixed some typos, and s/acpi/ACPI/, s/ioapic/IOAPIC/ throughout.
* Fixed a warning from 0-day testing.
