X-Git-Tag: omap-for-v4.3/fixes-rc1~87^2~114

kernel/kthread.c:kthread_create_on_node(): clarify documentation

- Make it clear that the `node' arg refers to memory allocations only:
  kthread_create_on_node() does not pin the new thread to that node's
  CPUs.

- Encourage the use of NUMA_NO_NODE.

[nzimmer@sgi.com: use NUMA_NO_NODE in kthread_create() also]
