Keith Owens e026cca0f2 [IA64] Add hotplug cpu to salinfo.c, replace semaphore with mutex ... Add hotplug cpu support to salinfo.c. The cpu_event field is a cpumask so use the cpu_* macros consistently, replacing the existing mixture of cpu_* and *_bit macros. Instead of counting the number of outstanding events in a semaphore and trying to track that count over user space context, interrupt context, non-maskable interrupt context and cpu hotplug, replace the semaphore with a test for "any bits set" combined with a mutex. Modify the locking to make the test for "work to do" an atomic operation. Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>		2006-01-13 14:22:35 -08:00
