 * The entries with indexes 0-31 contain the corresponding vector registers.

 * quadword (since it must be copied via a vector register to/from storage) 
 * or as a word.  
 *
 * 64-bit kernel notes: The entry at index 33 contains the vrsave as the first  
 * word (offset 0) within the quadword.
 *
 * This definition of the VMX state is compatible with the current PPC32 
 * ptrace interface.  This allows signal handling and ptrace to use the same 
 * structures.  This also simplifies the implementation of a bi-arch 
 * (combined (32- and 64-bit) gdb.

 * Note that it's _not_ compatible with 32 bits ucontext which stuffs the
 * vrsave along with vscr and so only uses 33 vectors for the register set
