866a4a667e phys addr arg of 0 must be possible for pt_writemap too (instead of meaning 
unmap).

68d0c4defe - code shared with exec() letting boot-time processes have 
their own fully fledged virtual address space and freeing
   their pre-allocated heap+stack area (necessary to let memory
   driver map in arbitrary areas of memory for /dev/mem without
   sys_vm_map)
 - small optimization preallocating memory on exec
 - finished VR_DIRECT physical mapping code

c078ec0331 Basic VM and other minor improvements. 
Not complete, probably not fully debugged or optimized.
