[Patch Part1 v8 00/37] Convert x86 to hierarchy irqdomain and stacked irqchip

[Jiang Liu]

Hi all,
	The generic hierarchy irqdomain and stacked irqchip implementation
has been merged into v3.19, so this patch set converts x86 interupt
management to hierarchy irqdomain and stacked irqchip. You may access it at:
https://github.com/jiangliu/linux.git irqdomain/x86_p1_v8

	This patch set has been reviewed several times and it missed v3.19
merging because several bugs got fixed just before the merging window.
The main changes since last review are:
1) Rebased the patch set onto v4.0-rc6.
2) Merged bugfixes into the patch introducing the bug so they don't break
   bisecting.

I will send out another following-on patch set to clean up code and interfaces
obseleted by this patch set.
