Subject: [GIT PULL] x86 fixes
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 bit:
out-of-topic modifications in x86-fixes-for-linus:
--------------------------------------------------
drivers/acpi/acpica/tbfadt.c # 878f4f5: x86: Trivial whitespace cleanups
Came with an x86 patch and looked trivial enough (a oneliner) to keep in
one piece. Len, do you mind it going this way?
Thanks,
Ingo
