Indeed - and I now see that commit when I switch over to my tip repo.

However 12665b35b0b4 is not present in linux-next of yesterday or today
(21/22) for some reason.  The tip/auto-latest merged into next has this:

commit 1974363f7e899dc1b9e6e774dc885c7980a7159b
Merge: 67367e2c3f76 7fd44dacdd80
Author: Ingo Molnar <mingo@...nel.org>
Date:   Thu May 8 12:40:28 2014 +0200

    Merge branch 'x86/x32'

as its top commit.  Today's auto-latest in tip shows a similar merge, but
with today's date (and it contains Boris' warning fix too.)  Adding Stephen
to CC in case it is something related to linux-next infrastructure.

Thanks,
Paul.
