I guess we could move that one to e.g. mm/mmflags.h as it's used also
outside of trace events anyway (mm/debug.c), but it's not something to
expose to general use in include/ But most includes are from proper
include/trace/events/*.h headers so dunno, maybe
include/trace/<something>/mmflags.h would be more appropriate.
