From b4531e863dbd06b5d336afefdb37483b690dea59 Mon Sep 17 00:00:00 2001

Subject: [PATCH] [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.
