Hi Linus.
A few kbuild updates that I liked to have applied before -rc2 but too
late.
Nothing earth shaking but the ubuntu fix for -fno-stack-protector
would be good to see soon in mailline.
shortlog and full patch below.
Can be pulled from:
git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild.git
Sam [heading for 2 weeks non-internet vacation]
Dave Jones:
kbuild: fix typo in modpost
Matthew Wilcox:
kconfig: support DOS line endings
Roman Zippel:
kconfig: correct oldconfig for unset choice options
Sam Ravnborg:
kbuild: hardcode value of YACC&LEX for aic7-triple-x
kbuild: version.h and new headers_* targets does not require a kernel config
kbuild: .gitignore utsrelease.h
kbuild: improve error from file2alias
kbuild: -fno-stack-protector is not good
