Linus Torvalds 7d20dd3294 x86/apic related update:

- A single commit which reduces cacheline misses in
     __x2apic_send_IPI_mask() significantly by converting
     x86_cpu_to_logical_apicid() to an array instead of using per CPU
     storage. This reduces the cost for a full broadcast on a dual socket
     system with 256 CPUs from 33 down to 11 microseconds.
