Subject: [git-pull -tip] Add -Werror to arch/x86/ files only and fix
warnings
Hello Ingo,
As per your suggestion, I added -Werror for x86/files only and
fix all remaining warnings on 32-bit and 64-bit defconfig and
allnoconfig.
Here is pull request:
The following changes since commit 3965887240cb092f0d568b53165da6a215c7937a:
Ingo Molnar (1):
Merge branch 'linus'
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/jaswinder/linux-2.6-tip.git master
Jaswinder Singh Rajput (2):
x86: Adding -Werror to arch/x86/ files only
x86: k8.h convert node_to_k8_nb_misc() from a macro to an inline function
