Subject: linux-next: manual merge of the tip tree with the idle-test tree

Hi all,

Today's linux-next merge of the tip tree got a conflict in
arch/x86/kernel/process.c between commits 68855c4b4018 ("x86 idle: move
mwait_idle_with_hints() to where it is used") and 42be29a3d2b7 ("2.6.40:
x86 idle: remove deprecated mwait_idle()") from the idle-test tree and
commit 349c004e3d31 ("x86: A fast way to check capabilities of the
current cpu") from the tip tree.

The former commits move and remove the code changed by the latter.  I
used the tip version but with this merge fix patch:
