Paul Jackson 7edc59628b [PATCH] cpuset: mark number_of_cpusets read_mostly ...

Mark cpuset global 'number_of_cpusets' as __read_mostly.

This global is accessed everytime a zone is considered in the zonelist loops
beneath __alloc_pages, looking for a free memory page.  If number_of_cpusets
is just one, then we can short circuit the mems_allowed check.

Since this global is read alot on a hot path, and written rarely, it is an
excellent candidate for __read_mostly.

Thanks to Christoph Lameter for the suggestion.
