Costa ShulyupinandGreg Kroah-Hartman 748fb68e11 hrtimer: Select housekeeping CPU during migration ...

[ Upstream commit 56c2cb1012 ]

During CPU-down hotplug, hrtimers may migrate to isolated CPUs,
compromising CPU isolation.

Address this issue by masking valid CPUs for hrtimers using
housekeeping_cpumask(HK_TYPE_TIMER).
