The kuser helpers on ARM are at a fixed location and mostly unused. Disable (and/or remove) them.

Mark Rutland noted this was fixed some time ago on arm32, and recently for arm64 compat.

v3.11 arm32: https://git.kernel.org/linus/f6f91b0d9fd971c6 ("ARM: allow kuser helpers to be removed from the vector page")

v5.2 arm64: https://git.kernel.org/linus/af1b3cf2c2a3f42bbb680812ff1bbd715ac8af69 ("arm64: compat: Add KUSER_HELPERS config option")
