x86/cpufeature: Carve out X86_FEATURE_*

2016-01-30T10:22:17+00:00

Move them to a separate header and have the following
dependency:

  x86/cpufeatures.h <- x86/processor.h <- x86/cpufeature.h

This makes it easier to use the header in asm code and not
include the whole cpufeature.h and add guards for asm.

x86: Tell irq work about self IPI support

2014-09-13T16:38:29+00:00

x86 supports irq work self-IPIs when local apic is available. This is
partly known on runtime so lets implement arch_irq_work_has_interrupt()
accordingly.

This should be safely called after setup_arch().
