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 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(). Acked-by: NPeter Zijlstra (Intel) <peterz@infradead.org> Cc: Ingo Molnar <mingo@kernel.org> Cc: Paul E.
