Symptoms:
	PHKL_26834:
	( SR:8606247529 CR:JAGae13966 )
	The lwp_stime field in the lwp_status structure filled in
	by the pstat_getlwp(2) syscall does not accurately reflect
	the system time consumed by the thread.

	PHKL_24580:
	( SR:8606200799 CR:JAGad69975 )
	This patch is a member of a set of patches needed to enable
	the HP-UX Processor Sets product (PROCSETS). When PROCSETS
	product is installed, it will install the full set of
	required patches for that product, including this patch.

	If the HP-UX Processor Sets product is not installed, this
	change will have no impact on your system.

Defect Description:
	PHKL_26834:
	( SR:8606247529 CR:JAGae13966 )
	The lwp_stime field is copied from the sum of an
	uninitialized variable and the interrupt time accumulated
	by the thread. The system time accumulated by the thread is
	not included.

	Resolution:
	The system time accumulated by the thread is copied to the
	sys_cyles variable before adding the interrupt time
	accumulated by the thread.

	PHKL_24580:
	( SR:8606200799 CR:JAGad69975 )
	This patch contains minor enhancements required to support
	the HP-UX Processor Sets product.

	Resolution:
	Enhancements added to return pset information for threads
	in pstat_getlwp() calls when Processor Sets product is
	enabled.
