It won't work for the 64-bit stuff but my understanding is the 32-bit
side of ARMv8 is similar enough to ARMv7 that a sequence would work.

It will need to be decided how we handle AArch64 (arm64) as some parts
are different, e.g. the instruction set and assembly is incompatible,
while other parts are shared, e.g. the page table layout are similar to
the long format in Cortex-A.
