Fix up the error return for nodemask containing nodes disallowed by
the process' current cpuset. Disallowed nodes are now silently ignored,
as long as the nodemask contains at least one node that is on-line,
allowed by the process' cpuset and has memory.
Now that we have a cpuset man page, we can refer to cpusets directly
in the man page text.
Thanks. Applied for man-pages-3.07.
Cheers,
Michael
