[PATCH] improve stop_machine performance
On systems with large cpu counts, we've been seeing long bootup times associated with stop_machine operations. I've noticed that by simply removing the creation of the workqueue and associated percpu variables in subsequent stop_machine calls, we can reduce boot times on a 1024 processor SGI UV system from 25-30 (... 4 Mar 2010 16:56
