  Modified files:
    sys/kern             kern_sysctl.c 
  Log:
  Touch all the pages wired by sysctl_wire_old_buffer() to avoid PTE
  modified bit emulation traps on Alpha while holding locks in the
  sysctl handler.
  
  A better solution would be to pass a hint to the Alpha pmap code to
  tell mark these pages as modified when they as they are being wired,
  but that appears to be more difficult to implement.
