Symptoms:
	PHKL_22787:
	Ported HP-UX patch PHKL_20170 for VVOS

	Based upon PHKL_20170:
	( SR: 4701423962 DTS: JAGaa07908 )
	PCI drivers supporting DLKM had problems with
	isrlink/isrunlink during a load/unload operation.

	( SR: 8606107126 DTS: JAGaa22790 )
	The Dino driver (GSCtoPCI) called device driver interrupt
	service routines at the wrong spinlock level.

Defect Description:
	PHKL_22787:
	Ported HP-UX patch PHKL_20170 for VVOS

	Based upon PHKL_20170:
	( SR: 4701423962 DTS: JAGaa07908 )
	Locking structures in the PCI code caused problems during
	DLKM load and unload of device drivers.
	Resolution:
	Removed and modified locking scructures to eliminate
	problems.

	( SR: 8606107126 DTS: JAGaa22790 )
	The Dino interrupt service routine was holding a spinlock
	while calling the device driver ineterrupt service routines,
	thereby increases the spinlock level.
	Resolution:
	Dino interrupt service routine code was modified such that
	device driver interrupt service routines are called at the
	correct spinlock level.
