Subject[patch 0/4] MTRR rendezvous deadlock fix and cleanups using stop_machine()
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
