Revision 5ca62d65030d8295f54c490d2072563545dbd9d9 authored by Andrew Morton on 18 June 2015, 18:01:11 UTC, committed by Linus Torvalds on 19 June 2015, 03:00:23 UTC
Revert commit 534b483a86e6 ("cpumask: don't perform while loop in
cpumask_next_and()").
This was a minor optimization, but it puts a `struct cpumask' on the
stack, which consumes too much stack space.
