Log Message:
Pull up following revision(s) (requested by hannken in ticket #1365):
        sys/arch/x86/x86/pmap.c: revision 1.190
Operation pmap_pp_clear_attrs() may remove the "used" attribute from a page
that is still cached in the TLB of other CPUs.
Call pmap_tlb_shootnow() here before enabling preemption to clear the
TLB entries on other CPUs.
Should prevent tmpfs data corruption under load.
