        src/sys/arch/x86/x86: pmap.c
        src/sys/arch/xen/x86: xen_pmap.c

Log Message:
Harden cross-cpu L3 sync - avoid optimisations that may race.
Update ci->ci_kpm_pdir from user pmap, not global pmap_kernel() entry which may 
get clobbered by other CPUs.
XXX: Look into why we use pmap_kernel() userspace entries at all.
