I've applied these on top of 3.17-rc1 and my Hyper-V guest with most
verification on bar DEBUG_PAGEALLOC boots without issue so long as I
have more than one CPU assigned (that issue is being investigated in
https://lkml.org/lkml/2014/8/26/271, [PANIC, hyperv] BUG: unable to
handle kernel paging request at ffff880077800004 (hv_ringbuffer_write)).

With DEBUG_PAGEALLOC on I hit https://lkml.org/lkml/2014/8/19/227 (BUG:
unable to handle kernel paging request at ffff8801f3febe63
(netvsc_select_queue)) but that's different to the above BUG_ONs.
