Hi Rusty,
Today's linux-next merge of the rr_cpumask tree got a conflict in
kernel/time/tick-common.c between commit
5762ba1873b0bb9faa631aaa02f533c2b9837f82 ("hrtimers: allow the
hot-unplugging of all cpus") from the timers tree and commit
6b954823c24f04ed026a8517f6bab5abda279db8 ("cpumask: convert kernel time
functions") from the rr_cpumask tree.
I fixed it up (see below) and can carry the fix as necessary.,
