I agree with you. I will write a separate new test. In the meanwhile I think it
should be okay to prepare and send just one patch.

This reverts commit 09ef193fef7efb0175a04634853862d717adbb95.
For C3000 family of SoCs, they have four ixgbe devices sharing a single MDIO
bus.
ixgbe_mii_bus_init() returns -ENODEV for other three devices. The propagation
of the error code makes other three ixgbe devices unregistered.

The struct flowi must never be interpreted by itself as its size
depends on the address family. Therefore it must always be grouped
with its original family value.
In this particular instance, the original family value is lost in

Hi Al,
this series changes import_iovec to transparently deal with compat iovec
structures, and then cleanups up a lot of code dupliation.
Changes since v3:
- fix up changed prototypes in compat.h as well
Changes since v2:
- revert the switch of the access process vm sysclls to iov_iter
- ref
There is no compat_sys_readv64v2 syscall, only a compat_sys_preadv64v2
one.

Split rw_copy_check_uvector into two new helpers with more sensible
calling conventions:
- iovec_from_user copies a iovec from userspace either into the provided
stack buffer if it fits, or allocates a new buffer for it. Returns
the actually used iovec. It also verifies that iov_len does
Use in compat_syscall to import either native or the compat iovecs, and
remove the now superflous compat_import_iovec.
This removes the need for special compat logic in most callers, and
the remaining ones can still be simplified by using __import_iovec
with a bool compat parameter.
