Hi Linus.
A few more kbuild goodies:
kbuild: explicit turn off gcc stack-protector
kbuild: introduce utsrelease.h
The stack-protector commit only adds the two -fno-stack-protector and
-fno-stack-protector-all flags to CFLAGS in top-level Makefile.
The utsrelease.h commit touches all present users of UTS_RELEASE.
Please pull from:

kbuild: explicit turn off gcc stack-protector
Ubuntu has enabled -fstack-protector per default in gcc
breaking kernel build. Explicit turn it off for now.
Later we may decide to make it configurable if the
kernel starts to support it.

kbuild: introduce utsrelease.h
include/linux/version.h contained both actual KERNEL version
and UTS_RELEASE that contains a subset from git SHA1 for when
kernel was compiled as part of a git repository.
This had the unfortunate side-effect that all files including version.h
would be recompiled when some git changes was made due to changes SHA1.
Split it out so we keep independent parts in separate files.
Also update checkversion.pl script to no longer check for UTS_RELEASE.
