Tidy up some loose ends.
i386/ia64/alpha - catch up to sparc64/ppc: - replace pmap_kernel() with refs to kernel_pmap - change kernel_pmap pointer to (&kernel_pmap_store) (this is a speedup since ld can set these at compile/link time) all platforms (as suggested by jake): - gc unused pmap_reference - gc unused pmap_destroy - gc unused struct pmap.pm_count (we never used pm_count - we track address space sharing at the vmspace)
