[Patch Part3 v3 00/38] Enable hierarchy irqdomian on x86 platforms

From: Jiang Liu
Date: Sat Nov 08 2014 - 13:10:38 EST


This is the last part to enable support of hierarchy domain on x86
platforms.

It first converts IOAPIC to support hierarchy irqdomain, then cleans
up all unused code and interfaces. It also introduces a kernel boot
parameter to configure CPU vector allocation policies.

It's based on my previous patch set at:
https://www.mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg760868.html
And you may access it at:
https://github.com/jiangliu/linux.git irqdomain/p3v3

It has been tested on Intel 64-bit server and 32-bit laptop. It also
passes Fengguang's 0day tests. Helps are welcomed for testing:
1) Intel MID platform
2) Intel CE or OLPC platforms

Patch 1-3 kills pre_init_apic_IRQ0().
Patch 4-9 convert IOAPIC to use hierarch irqdomain
Patch 10-36 clean up code, unused interfaces etc.
Patch 37-38 introduces a mechanism to configure CPU vector allocation
policies.
