I think this specific task (Disable arm32 kuser helpers) has already
been done, and the ticket is stale.

On arm CONFIG_KUSER_HELPERS can be disabled on kernels that don't need
to run on HW prior to ARMv6. See commit:

  f6f91b0d9fd971c6 ("ARM: allow kuser helpers to be removed from the vector page")

On arm64, CONFIG_KUSER_HELPERS can be disabled on any kernel. See

  1b3cf2c2a3f42b ("arm64: compat: Add KUSER_HELPERS config option")
