Hi Akio,

   Why does efi_ucwb() only check certain types of ranges for having
both UC and WB attributes.  Seems like the types might be implementation
specific.  I'm also a little concerned about scanning the EFI memory
map, but I guess this is expected to be a rare event.  Is there an
approach we could take to prevent these cases from happening (for a well
behaved guest) rather than catching them at the end?  Thanks,

        Alex
