svn commit: r210780 - in head/sys/amd64: amd64 include

New Revision: 210780
URL: http://svn.freebsd.org/changeset/base/210780

Log:
  Rearrange struct pcb.  r177532 (CVS r1.64 of pcb.h) moved pcb_flags to make
  better use of cache lines by placing it before pcb_save (now pcb_user_save),
  which is moved to the end of pcb since r210777.
