Date:           Mon Nov 15 17:32:02 UTC 2010

Modified Files:
        src/sys/miscfs/genfs [uebayasi-xip]: genfs_io.c
        src/sys/uvm [uebayasi-xip]: uvm_page.c uvm_page.h

Log Message:
Move zero-page into a common place, in the hope that it's shared
for other purposes.

According to Chuck Silvers, zero-page mappings don't need to be
explicitly unmapped in putpages().  Follow that advice.
