| |
Ingo, Peter:
Here is the updated MTRR stop machine patch-set.
First patch is a quick fix targeting 3.0 and the stable kernels. This fixes the boot deadlock reported in the https://bugzilla.novell.com/show_bug.cgi?id=672008
Second patch reorganizes the stop_cpus() code.
Third patch introduces stop_machine_from_offline_cpu() so that we can do stop machine from the cpu hotplug path, where the calling cpu is not yet online.
Fourth patch uses the stop_machine() and stop_machine_from_offline_cpu() to implement the x86 MTRR rendezvous sequence and thus remove the duplicate implementation of stop machine using stop_one_cpu_nowait().
thanks, suresh
