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.
