Symptoms:
	PHKL_26192:
	( SR:8606232843 CR:JAGae02071 )
	This product update is part of a set needed to enable the
	optional HP-UX Interrupt Migration feature. Upon
	installation, the HP-UX Interrupt Migration bundle
	(IM11i) will install the full set of product updates
	(including this one) necessary to enable the Interrupt
	Migration feature.

	If the HP-UX Interrupt Migration product is not installed,
	this product update will have no impact on your system.

	PHKL_24163:
	( SR:8606186123 CR:JAGad55328 )
	ioscan -k takes a long time to complete on systems with a
	large configuration. For example, ioscan -kf would take
	approximately 13+ minutes on a SuperDome system with 8000+
	disks.

Defect Description:
	PHKL_26192:
	( SR:8606232843 CR:JAGae02071 )
	This product update contains minor enhancements required to
	enable the HP-UX Interrupt Migration product.

	Resolution:
	Added new data structures and functions to the I/O
	sub-system for interrupt migration.

	PHKL_24163:
	( SR:8606186123 CR:JAGad55328 )
	Old interfaces to the I/O tree only provided a field of
	information for one device at a time. A lot of system calls
	had to be made to obtain complete information for the
	entire I/O tree.

	Resolution:
	New interfaces have been implemented which provide multiple
	information on multiple devices with one system call.
	In this way, context switchs between kernel and user space
	are decreased.
