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

Log Message:
On xen, prevent cached PDP objects from being reused by pool_cache(9),
since they are "pinned" on the hypervisor and thus R/O for the domU.

Separately, after every per-cpu pmap pdir entry reset, make sure that
the corresponding L3 PTP pointers are flushed from all cpus with the
pmap loaded. Enforce this immediately via pmap_tlb_shootnow();
