Christoph Hellwig and a few others spent a huge effort on removing
set_fs() from most of the important architectures, but about half the
other architectures were never completed even though most of them don't
actually use set_fs() at all.
I did a patch for microblaze at some point, which turned out to be fairly
generic, and now ported it to most other architectures, using new generic
implementations of access_ok() and __{get,put}_kernel_nocheck().
Three architectures (sparc64, ia64, and sh) needed some extra work,
which I also completed.
The final series contains extra cleanup changes that touch all
architectures. Please review and test these, so we can merge them
for v5.18.
The series is available at
https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=set_fs-2
for testing.
I've added the updated contents to my asm-generic tree now to put them
into linux-next.
