  h8300: remove stale bindings and symlink (2022-05-20 22:40:56 +0200)

----------------------------------------------------------------
asm-generic changes for 5.19

The asm-generic tree contains three separate changes for linux-5.19:

- The h8300 architecture is retired after it has been effectively
  unmaintained for a number of years. This is the last architecture we
  supported that has no MMU implementation, but there are still a few
  architectures (arm, m68k, riscv, sh and xtensa) that support CPUs with
  and without an MMU.

- A series to add a generic ticket spinlock that can be shared by most
  architectures with a working cmpxchg or ll/sc type atomic, including
  the conversion of riscv, csky and openrisc. This series is also a
  prerequisite for the loongarch64 architecture port that will come as
  a separate pull request.

- A cleanup of some exported uapi header files to ensure they can be
  included from user space without relying on other kernel headers.
