Okay, then could you please check which part is really required?

- protection by _cpu_exception_suspend()/_cpu_exception_resume() pairs
  on accesses to TLB settings in mmu*.c
- protection by splvm()/splx() pairs on changing pv map in pmap.c
- passing protection bits to flags too on pmap_enter(9) in
  vm_machdep.c:vmapbuf()
