Talked to Chris offline.  He said that in his tests the other patches
weren't needed, so he didn't list any other patches.  Things just
worked for him.  ...so I guess he did post the instructions that
worked for him.  Sorry for the complaint.  Possibly things are
different on "next-20141112" and that's where Chris said he tested.

I know that I personally needed some of the extra patches.  I guess
the USB one wasn't truly needed (only needed for hotplug), but for me
things were unhappy without SMP.  It was hanging when trying to turn
off secondary CPUs.  I didn't dig, though.  The clocksource patches
are needed for me because I'm using an old bootloader, but I think
they're also relevant for S2R because (I'm told) we can lose the
virtual offset at suspend time in certain modes.
