RISC-V: Add support for rv32 userspace via COMPAT

The RISC-V port supports the rv32i and rv64i base ISAs, but provides no
mechanism to run 32-bit userspace on 64-bit systems. This adds that
support, via the COMPAT framework. As the RISC-V ISAs (and uABIs) were
developed concurrently, the resulting compat support is mostly generic.

This includes a handful of cleanups to the generic compat infrastructure
to more cleanly support RISC-V, followed by the RISC-V implementation.

"There are three sets of updates for 5.18 in the asm-generic tree:

- The set_fs()/get_fs() infrastructure gets removed for good.

This was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly tricky
and error-prone code. There is a small merge conflict against a
parisc cleanup, the solution is to use their new version.

- The nds32 architecture ends its tenure in the Linux kernel.

The hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.

files to pass the compile-time checks"

Merge branch 'set_fs-4' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic into asm-generic

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.

There are no remaining callers of set_fs(), so CONFIG_SET_FS

This turns access_ok() into a cheaper check against TASK_SIZE_MAX.

As CONFIG_SET_FS is now gone, drop all remaining references to

everywhere. Kernel threads are not allowed to access __user pointers
anyway.
