What rev is this based on? When I apply it to Linus latest (aad7fb916), it
fails in arch/tile/kernel/time.c and arch/tile/kernel/vdso/vgettimeofday.c
(see below)
It's based on the linux-tile tree (on kernel.org under
cmetcalf/linux-tile.git), which was last synced up at 3.16-rc7. I'll refresh
the tree to pick up Thomas's recent changes that were queued for 3.17. Thanks.
