Subject: [Patch Part2 v4 00/33] Clean up obsoleted x86 interrupt manangement code and interfaces

This is a following-on patch of "[Patch Part1 v7 00/38] Convert x86 to
hierarchy irqdomain and stacked irqchip" at
https://lkml.org/lkml/2015/1/19/685

The precedent patch has convert x86 interrupt management subsystem to
hierarchy irqdomain and stacked irqchip, so this patch set cleans up
code and interfaces obsoleted by the precedent patch set.

Main changes since last version:
1) rebased onto v3.19-rc5
2) add patch 33 to avoid memory allocation/free when assigning CPU vector 

Regards,
Gerry
