Current common codes uses PAGE_OFFSET to indicate a bad host virtual
address.
As this check won't work on architectures that don't map kernel and
user memory
into the same address space (e.g. s390), it is moved into architcture
specific
code.

Nit: This breaks arm64. I suppose the patches have been created before
the arm64 code got merged, so I'd expect the next version of this series
to deal with arm64 as well.
Thanks,
