Linus,
Please pull the latest x86-fixes-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git x86-fixes-for-linus
This includes your patch for disabling static NOPL entirely on 32
bits; as discussed yesterday the -Wa,-mtune=generic32 patches are
deferred to post-27.
Thanks,
-hpa
