Subject: Hyp  compat_memory_op() and 256 GB PV

Hi,

Moving on to 256 GB guest, the hyp is failing the XENMEM_populate_physmap
hcall in compat_memory_op(). The problem is size too large for continuation
encoding:

     /* Is size too large for us to encode a continuation? */
     if ( cmp.rsrv.nr_extents > (UINT_MAX >> MEMOP_EXTENT_SHIFT))
         return start_extent;

      for 256 GB : nr_extents == 0x4000000

  Currently at a loss on this one!

Thanks,
Mukesh
