Log Message:
Pull up following revision(s) (requested by rmind in ticket #314):
        sys/arch/xen/x86/cpu.c: revision 1.92
        sys/kern/subr_kcpuset.c: revision 1.6
        sys/sys/kcpuset.h: revision 1.6
        sys/arch/xen/x86/x86_xpmap.c: revision 1.44
Few fixes for Xen:
- cpu_load_pmap: use atomic kcpuset(9) operations; fixes rare crashes.
- Add kcpuset_copybits(9) and replace xen_kcpuset2bits().  Avoids incorrect
  ncpu problem in early boot.  Also, micro-optimises xen_mcast_invlpg() and
  xen_mcast_tlbflush() routines.
Tested by chs@.
