[Patch v4 00/23] Improve ACPI resource parsing interfaces and enable IOAPIC hotplug

[Jiang Liu]

During enabling ACPI based IOAPIC hotplug, Thomas noticed some issues
in ACPI resource parsing interfaces. So this is an effort to improve them.

Patch 1 refines ACPICA resource descriptors, which has already been
merged into "git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git bleeding-edge"

Patch 2-12 improve ACPI resource parsing interfaces and also fixes some
bugs.

Patch 13-20 try to share the common data structure resource_list_entry
between PCI and ACPI. It may also be shared with PNP too.

Patch 21-23 enable ACPI based IOAPIC hotplug.

The patchset is based on v3.19-rc6+ and passed Fengguang's 0day test
suite. You may get it from:
https://github.com/jiangliu/linux.git acpires_v2

V3->V4:
1) rename resource_list_entry as resource_entry to avoid conflicts
2) kill pcibios_disable_device()
3) Patch 1-16 are the same with v3


V2->V3:
1) Split out the patch to fix bug in io resource check according to Bjorn's
   suggestion
2) Fix minor coding style bugs

V1->V2:
1) Refine the way to share common code between address space and extended
   address space.
2) Relax some checks to avoid regressions according to Rafael's suggestions.
3) Introduce struct resource_win to avoiding add extra parameter "offset"
   to several interfaces.
4) Add patches to enable ACPI based IOAPIC hotplug, which has been reviwed
   several rounds.
5) Rebase to v3.19-rc6+
