Symptoms:
	PHKL_22788:
	Ported HP-UX patch PHKL_20163 to VVOS

	Based upon PHKL_20163
	( SR: 8606107507 DTS: JAGab77743 )
	Newer workstations (B1000, C3000, J5000, J7000) and all
	others released after 06/1999 running a 64-bit kernel may
	panic during boot with an unaligned data reference trap.

Defect Description:
	PHKL_22788:
	Ported HP-UX Patch PHKL_20163 to VVOS

	Based upon PHKL_20163
	( SR: 8606107507 DTS: JAGab77743 )
	When the kernel allocates a buffer to hold LPMC data it
	does not round the buffer size up to a multiple of 8 bytes.
	This causes an 8-byte data field within the buffer to be
	improperly aligned.  When the kernel accesses this field,
	it causes an unaligned data reference trap.

	Resolution:
	Modified code that allocates the LPMC data buffer to round
	the size up to an 8-byte boundary.
