- This option adds the workaround for ARM Cortex-A715 erratum 2645198.
-
- If a Cortex-A715 cpu sees a page mapping permissions change from executable
- to non-executable, it may corrupt the ESR_ELx and FAR_ELx registers on the
- next instruction abort caused by permission fault.
-
- Only user-space does executable to non-executable permission transition via
- mprotect() system call. Workaround the problem by doing a break-before-make
- TLB invalidation, for all changes to executable user space mappings.

- If unsure, say Y.
