[OLK-5.10 1/4] cpumask: Introduce DYING mask

From: Peter Zijlstra <peterz(a)infradead.org> mainline inclusion from mainline-v5.13-rc1 commit e40f74c535b8a0ecf3ef0388b51a34cdadb34fb5 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6VS35 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Introduce a cpumask that indicates (for each CPU) what direction the CPU hotplug is currently going. Notably, it tracks rollbacks. Eg. when an up fails and we do a roll-back down, it will accurately reflect the direction.

It also avoids the potential KASAN / syzkaller failure, as a bonus.
