kthread: add the helper function kthread_run_on_cpu()
Add a new helper function kthread_run_on_cpu(), which includes
kthread_create_on_cpu/wake_up_process().
In some cases, use kthread_run_on_cpu() directly instead of
kthread_create_on_node/kthread_bind/wake_up_process() or
kthread_create_on_cpu/wake_up_process() or
kthreadd_create/kthread_bind/wake_up_process() to simplify the code.
[akpm@linux-foundation.org: export kthread_create_on_cpu to modules]
