  Modified files:
    sys/miscfs/procfs    procfs_vnops.c 
  Log:
  Avoid a 64-bit division in procfs_readdir().  Fixed related overflows.
  Check args using the same expression as in fdesc and kernfs.  The check
  was actually already correct, modulo overflow.  It could be tightened
  up to either allow huge (aligned) offsets, treating them as EOF, or
  disallow all offsets beyond EOF.
  
  Didn't fix invalid address calculation &foo[i] where i may be out of
  bounds.
  
  Didn't fix shooting of foot using a private unportable dirent struct.
