  Log:
  MFC [1.92] Critical non-SMP fix.  Without this, a context switch happens
  for *every* syscall, slowing down syscalls a lot.  (eg: 1.6 million
  getpid() calls per second drops to 400K calls/sec)
  
  Matt forgot this when he MFC'ed the SMP changes to RELENG_4.  Without
  this, AST_RESCHED is an undefined symbol in /kernel.  It is particularly
  interesting that gas/ld do not notice it.
