What defines "non-standard" here ? Isn't this a sparse problem that should possibly
be fixed in sparse instead ?

[ I don't mind changing it as the 0bXXXX notation doesn't seem to be used much
   in the kernel, but we should not claim something to be non-standard if it is
   just not widely used. As normal compilation doesn't seem to have a problem,
   we should be sure that it is non-standard if we claim it to be non-standard. ]

Thanks,
Guenter
