Nick Piggin 5c1e176781 [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).
