Defect Description:
	PHKL_28839:
	( SR:8606287851 CR:JAGae51784 )
	The root cause of this defect is the incorrect
	implementation of the p2p_bcopy feature.

	Resolution:
	1. Correct definition of alignment macro to provide correct
	alignment.
	2. Correct invocation of alignment macro by passing the
	correct argument.
	3. Modify code to remember the original MALLOC address.
