hi,

i've put some code at:
	ftp://ftp.netbsd.org/pub/NetBSD/misc/yamt/vmem/

which includes:
	1. implement solaris-like vmem.
	   (still primitive, but should work enough for the following purposes)
	2. implement solaris-like kmem_alloc/free api, using #1.
	   (note: this implementation is backed by kernel_map, thus can't be
	   used from interrupt context.)
	3. make amap to use kernel_map rather than kmem_map, using #2.

i'll commit them for #3 unless anyone objects.
