Subject: [Patch Part3 v4 00/38] Enable hierarchy irqdomian on x86 platforms
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:
http://lkml.org/lkml/2014/11/25/10
And you may access it at:
https://github.com/jiangliu/linux.git irqdomain/p3v4
It has been tested on Intel 64-bit server and 32-bit laptop. Joerg has
helped to test on AMD platforms. 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.
V3->V4:
1) Rebase onto latest prerequisition patch sets
