As part of the effort to move to mm->flags becoming a bitmap field, convert existing users to making use of the mm_flags_*() accessors which will, when the conversion is complete, be the only means of accessing mm_struct flags. This will result in the debug output being that of a bitmap output, which will result in a minor change here, but since this is for debug only, this should have no bearing. Otherwise, no functional changes intended.
