Symptoms:
	PHKL_22771:
	( SR: 8606166611  CR: JAGad35898 )
	Cannot create file system swap greater than 4GB.

	PHKL_17801:
	swapinfo(1m) reports more space "free" than "available";
	panics with "swapchunk: swapspace exhausted"

Defect Description:
	PHKL_22771:
	( SR: 8606166611  CR: JAGad35898 )
	For file system swap over 4GB, data types used in
	intermediate swap calculations overflowed.

	Resolution:
	Made necessary type promotions to avoid data type
	overflow.

	PHKL_17801:
	swapon had a race condition in it for MP machines that
	would cause a swap device to be counted twice; this
	could be observed by running multiple "swapon -a"
	commands on different processors
	Resolution:
	Used swap lock and a bit in flag field to protect devices
	from being enabled more than once.
