Symptoms:
	PHKL_23011:

	(SR: 8606103195 DTS: JAGaa13078)

	Manager (VxVM) product may fail unexpectedly on a read

Defect Description:
	PHKL_23011:
	Ported HP-UX Patch PHKL_19246 to VVOS.

	Based upon PHKL_19246:
	(SR: 8606103195 DTS: JAGaa13078)
	any_superpages_present() will fail to detect superpages when
	all these conditions apply-

	-- the first page in a range is 4K
	-- the next page is a superpage
	-- the offset to start checking for "superness" is not 4K
	   aligned
	-- the length (in bytes) of the range to be checked is <=4K

	Resolution:
	The fix is to make sure we start examining pages at a 4K
	boundary.
