	include/linux/gfp.h and include/trace/events/gfpflags.h are out of sync. When tracing is enabled, certain flags are not recognised and the text output is less useful as a result. Add the missing flags.

2010-08-09	vmscan: tracing: add trace events for kswapd wakeup, sleeping and direct reclaim	Mel Gorman
	Add two trace events for kswapd waking up and going asleep for the purposes of tracking kswapd activity and two trace events for direct reclaim beginning and ending. The information can be used to work out how much time a process or the system is spending on the reclamation of pages and in the case of direct reclaim, how many pages were reclaimed for that process. High frequency triggering of these events could point to memory pressure problems.
