New Revision: 245819
URL: http://svnweb.freebsd.org/changeset/base/245819

Log:
  MFP4 change 219820
  
  Add a missing 0 to the mask for byte0 of C_SIZE.
  
  The previous mask (0xc) worked except that the last 0-1536K of the disk
  could not be accessed since we were shifting the (wrong) bits we did
  mask off the right edge.
