 ****************************** SPECIAL WARNING: ******************************
 
+20161119:
+	The layout of the pmap structure has changed for powerpc to put the pmap
+	statistics at the front for all CPU variations.  libkvm(3) and all tools
+	that link against it need to be recompiled.
+
 20161030:
 	isl(4) and cyapa(4) drivers now require a new driver,
 	chromebook_platform(4), to work properly on Chromebook-class hardware.
