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. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com> 2008-06-18 15:08:48 +00:00			`#ifndef ASM_X86__IDLE_H`

[PATCH] x86_64: Add idle notifiers This adds a new notifier chain that is called with IDLE_START when a CPU goes idle and IDLE_END when it goes out of idle. The context can be idle thread or interrupt context. Since we cannot rely on MONITOR/MWAIT existing the idle end check currently has to be done in all interrupt handlers. They were originally inspired by the similar s390 implementation. They have a variety of applications: - They will be needed for CONFIG_NO_IDLE_HZ - They can be used for oprofile to fix up the missing time in idle when performance counters don't tick. - They can be used for better C state management in ACPI - They could be used for microstate accounting. This is just infrastructure so far, no users. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org> 2006-01-11 21:44:36 +00:00
