        src/sys/arch/x86/include: pmap.h
        src/sys/arch/x86/x86: pmap.c
        src/sys/arch/xen/include: xenpmap.h
        src/sys/arch/xen/x86: xen_pmap.c

Log Message:
Expose the PG_k #define pt/pd bit to both xen and "baremetal" x86. This is 
required, since kernel pages are mapped with user permissions in XEN/amd64 
since the VM kernel runs in ring3. Since XEN/i386(including PAE) runs in ring1, 
supervisor mode is appropriate for these ports. We need to share this since the 
pmap implementation is still shared. Once the xen implementation is 
sufficiently independant of the x86 one, this can be made private to 
xen/include/xenpmap.h
