[patch] x86, mtrr: use stop machine context to rendezvous all the cpu's
Use the stop machine context rather than IPI's to rendezvous all the cpus for MTRR initialization that happens during cpu bringup or for MTRR modifications during runtime. This avoids deadlock scenario (reported by Prarit) like: cpu A holds a read_lock (tasklist_lock for example) with irqs enabled cpu B wa... 30 Jul 2010 15:14
