        src/sys/uvm: uvm_device.c uvm_fault.c uvm_glue.c uvm_km.c uvm_page.c
            uvm_pager.c
        src/sys/vm: pmap.h
Log Message:
Add a new `access type' argument to pmap_enter().  This indicates what type of
memory access a mapping was caused by.  This is passed through from uvm_fault()
and udv_fault(), and in most other cases is 0.
The pmap module may use this to preset R/M information.  On MMUs which require
R/M emulation, the implementation may preset the bits and avoid taking another
fault.  On MMUs which keep R/M information in hardware, the implementation may
preset its cached bits to speed up the next call to pmap_is_modified() or
pmap_is_referenced().
