As RTH says, for 4.0 the fix for this regression is simpler.
For the longer term I think we should look a little more broadly
at what would be needed for supporting system emulation mode
CPUs which are nominally aarch64 but configured to boot into
aarch32 on reset, to see whether the linux-user mode falls
out as a subset of that. (It may be that it does not, but
it would definitely be better if we can avoid having to
duplicate the ID register and feature settings for the
64-bit CPUs in both cpu64.c and cpu.c.)
