o) Use the direct map where possible for uiomove_fromphys, based on code from
sparc64.
o) Use uiomove_fromphys rather than the broken fpage mechanism for /dev/mem.
o) Update sf_buf allocator to not share buffers and to do a pmap_qremove when
done with an sf_buf so as to better track valid mappings.
