Use of regular cmpxchg and xchg requires the\ndetermination of the address of the per cpu data before regular cmpxchg\nor xchg which therefore cannot be atomically included in an xchg or\ncmpxchg without segment override.\n\ntj: - Relocated new ops to conform better to the general organization.\n    - This patch contains a trivial comment fix.\n\nSigned-off-by: Christoph Lameter \u003ccl@linux.com\u003e\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n",
