:with the pmap of the current process, pmap_kextract won't work even for
:the current address space because kva is not mapped into each process's
:pmap.

: pmap = &curproc->p_vmspace->vm_pmap;
:...
: pa = trunc_page(pmap_extract(pmap, (vm_offset_t)addr));

:This should work for all platforms.

:The rest looks fine apart from style bugs.

strange about one of the architectures but I could not recall what it
was.
