[PATCH] i386: Use X86_EFLAGS_IF in irqflags.h.
Move X86_EFLAGS_IF et al out to a new header: processor-flags.h, so we can include it from irqflags.h and use it in raw_irqs_disabled_flags(). As a side-effect, we could now use these flags in .S files. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Andi Kleen <ak@suse.de>
