Module Name:    src

Modified Files:
        src/sys/uvm: uvm_page.c uvm_page.h

Log Message:
Abstraction fix; move physical address -> physical segment "reverse"
lookup code from uvm_page.h to uvm_page.c.

This code is used by some pmaps to lookup per-page state (PV) from
per-segment metadata (struct vm_physseg).  This is not needed if
UVM looks up physical segment once in fault handler, then directly
passes it to pmap.  This change helps transition to that model.

The only users of vm_physseg_find() are pmap_motorola.c and
powerpc/ibm4xx/pmap.c.

Tested By:      Compiling and running powerpc/ibm4xx/pmap.c
                (evbppc/conf/OPENBLOCKS266)
