Impact: hang which happens across CPU offline/online on AMD C1E systems. When a CPU goes offline then the corresponding bit in the broadcast mask is cleared. For AMD C1E enabled CPUs we do not reenable the broadcast when the CPU comes online again as we do not clear the corresponding bit in the c1e_mask, which keeps track which CPUs have been switched to broadcast already. So on those !$@#& machines we never switch back to broadcasting after a CPU offline/online cycle. Clear the bit when the CPU plays dead. Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

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: NVegard Nossum <vegard.nossum@gmail.com>

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: NAndi Kleen <ak@suse.de> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>
