This patch is for google/main which is 4.7 based, but the validated
version is in google_46 branch (which is based on 4.6).

By the way (given that you are from intel),  do you know if linux
kernel can be built with icc with PGO turned on? Our intern Xiaotian
has tried to use icc (12.0) to built kernel, and had some problems.
The bootable kernel built with icc + gcc (for those failed with icc)
does not perform quite well.
