From 77ef50a522717fa040636ee1017179ceba12ff62 Mon Sep 17 00:00:00 2001 From: Vegard Nossum Date: Wed, 18 Jun 2008 17:08:48 +0200 Subject: x86: consolidate header guards This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores.

The only user of restore_interrupts is in traps_32.c. Introduce conditional_sti for i386 and remove restore_interrupts.
