It appears to work here so far. I did not run massive i/o test suite
but it now passes basic multiple kernel unpacking in parallel tests
(before it didnt' even recognize the partition table).

So the patch - at least basically - works.

Except that we now have code duplication in kernel. Look at
fs/compat.c:compat_do_readv_writev() - it does the same as
compat_rw_copy_check_uvector() plus a bit more. I guess it
is a good idea to use compat_rw_copy_check_uvector() in
compat_do_readv_writev() to build the compat vectors...

Thank you for the patch and the fix!
