Cover letter [Patch 0/2] Optimize CPU vector allocation for NUMA systems

Hi all,
This is a small patch set based on tip/x86/apic.
This first patch is a bugfix for tip/x86/apic. And the second patch is an enhancement to optimize CPU vector allocation on NUMA systems. It introduces a mechanism to allocate CPU vectors from device local NUMA node and a kernel parameter to enable/disable the optimization.

Thanks!
Gerry
