Hi,
This patch set introduces a new instruction support on AMD Carrizo (Family
15h, Model 60h-6fh). It adds mwaitx idle function with a configurable
timer. The user can configure the idle method and timer value via the idle
kernel parameter.
Some discussions of the background, please see:

http://marc.info/?l=linux-kernel&m=143161327003541&...
They are rebased on tip/sched/core.
Thanks,
Rui
