  Log:
  md_hash field in g_eli_metadata structure is not 4 byte aligned, which
  case panic on sparc64.
  
  The problem is in MD5(9) implementation. The Encode() function takes
  'unsigned char *output' as its first argument, which is then assigned to
  'u_int32_t *op'. If the 'output' argument is not 4 byte aligned (and in
  geli(8) case it is not), sparc64 machine will panic.
  
  I don't know how to fix MD5(9) in a clean way, so I'm implementing a
  work-around in geli(8).
