Symptoms:
	PHKL_27321:
	( SR:8606251256 CR:JAGae17322 )
	Customers who wish to use certain kernel modules (those
	that use the Kernel Registry Service tree to store driver
	information) will not be able to access those modules.
	In addition, customers could experience a possible
	6 minute system hang on top of not being able to access
	the desired module.

Defect Description:
	PHKL_27321:
	( SR:8606251256 CR:JAGae17322 )
	Kernel Registry Service states that the tree information
	would be available prior to I/O initialization. It was
	actualy not available until after I/O initialization.

	Resolution:
	The Kernel Registry Service boot sequence function will be
	split into two separate routines.  One will allow the
	Kernel Registry Service to be available earlier in boot,
	and prior to I/O initialization.  The other is needed to
	free the memory allocated (in the first routine) after
	swap space has been initialized.

Enhancement:
	No

	This patch is part of a set of patches needed to enable
	earlier availability of the Kernel Registry Service.
	To obtain the early availability of Kernel Registry,
	the patch PHKL_27096 will also need to be installed
	on the system.  If patch PHKL_27096 is not installed
	on the system, then the Kernel Registry service will
	not be available prior to I/O initialization.
