Modified files:
	group/gfs_controld: plock.c 

Log message:
	bz 429546
	
	Fix an alignment problem with ppc64.  Things work if we do the
	byte-swapping on the original structure and then copy it into the
	final buffer, instead of copying first and then trying to do the
	byte-swapping at an offset within the send buffer.
