Arnd Bergmann 5b3a45eedd ethtool: improve compat ioctl handling 
[ Upstream commit dd98d2895d ]

The ethtool compat ioctl handling is hidden away in net/socket.c,
which introduces a couple of minor oddities:

- The implementation may end up diverging, as seen in the RXNFC
  extension in commit 84a1d9c482 ("net: ethtool: extend RXNFC
  API to support RSS spreading of filter matches") that does not work
  in compat mode.

- Most architectures do not need the compat handling at all
  because u64 and compat_u64 have the same alignment.

- On x86, the conversion is done for both x32 and i386 user space,
  but it's actually wrong to do it for x32 and cannot work there.

- On 32-bit Arm, it never worked for compat oabi user space, since
  that needs to do the same conversion but does not.

- It would be nice to get rid of both compat_alloc_user_space()
  and copy_in_user() throughout the kernel.

None of these actually seems to be a serious problem that real
users are likely to encounter, but fixing all of them actually
leads to code that is both shorter and more readable.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
