Today's -next fails to build both arm and arm64 allmodconfig due to the
above errors, introduced in commit ffa415245b8666c44d (bus: arm-ccn:
cpumask attribute).  Judging from the name of the symbol it appears that
the code is peering into hrtimer implementation details and indeed it
was removed in commit 58f1f803f1d6ef9 (hrtimer: Get rid of
__hrtimer_start_range_ns()) which has a commit message suggsting that
this has indeed been explicitly removed and no new references should be
added.
