Modified Files:
        src/sys/arch/x86/x86: pmap.c

Log Message:
Add a NULL check on the structure pointer, not to retrieve its first field
if it is NULL. The previous code was not buggy strictly speaking. This
change probably doesn't change anything, except removing assumptions in the
compiler optimization passes, which too probably doesn't change anything in
this case.
