- Actually I meant "don't expose uvm_page.h via uvm_extern.h".

        uvm_extern.h is for usual uvm(9) API users.
        uvm.h is only for VM and filesystem internal codes.

- Hiding vm_page / vm_physseg internal is also good in abstraction POV.

- Now I don't need to recompile ~everything under sys/dev after changing
  uvm_page.h.  This saves lots of time (5min -> 30sec).
