  Modified files:
    sys/i386/include     globals.h 
  Log:
  Implement optimized PCPU accessors.  These are necessary to support a
  pre-emptable kernel.  For variables of size 4 bytes or less they compile
  to a single instruction, which does not allow a process to migrate cpus
  in the middle, and get the value for the "wrong" cpu.
