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.
