Thanks for picking up my patches and integrating them properly
with the reset code.
But sadly your changes somehow break hppa 64-bit CPU support.
I think it's to when the reset code is called.
Likely hppa_is_pa20() called *before* CPU reset...?

Easy reproducer (no other options/disc/network needed):
./qemu-system-hppa -smp cpus=4 -nographic -machine C3700
