CVS commit: src/sys

Module Name:    src
Committed By:   rmind
Date:           Wed Jun  6 22:22:42 UTC 2012

Modified Files:
        src/sys/arch/xen/x86: cpu.c x86_xpmap.c
        src/sys/kern: subr_kcpuset.c
        src/sys/sys: kcpuset.h

Log Message:
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@.
