FTR, this (now commit ce70df089143c493) fixes the strange crashes I saw
with plain v4.11-rc2 and renesas-devel-20170313-v4.11-rc2 during shutdown on
Renesas R-Car Gen2 (arm) and R-Car Gen3 (arm64) (but not on older
SH/R-Mobile), and that I bisected to commit c2febafc6773.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
