[PATCH] sched: force /sbin/init off isolated cpus
Force /sbin/init off isolated cpus (unless every CPU is specified as an isolcpu). Users seem to think that the isolated CPUs shouldn't have much running on them to begin with. That's fair enough: intuitive, I guess. It also means that the cpu affinity masks of tasks will not include isolcpus by default, which is also more intuitive, perhaps. /sbin/init is spawned from the boot CPU's idle thread, and /sbin/init starts the rest of userspace. So if the boot CPU is specified to be an isolcpu, then prior to this patch, all of userspace will be run there. (throw in a couple of plausible devinit -> cpuinit conversions I spotted while we're here).
