[PATCH v2 0/2] target/ppc: more cleanups around the 403 CPUs

Posted by Cédric Le Goater 2 years, 3 months ago

Hello,

This is a follow up of "target/ppc: Finish removal of 401/403 CPUs".

To "finish" the removal, we need to get rid of the 403 protection
registers under CPUPPCState. This is done after having removed the
last user of .load_state_old. This change breaks migration
compatibility with very old versions of QEMU but it should not be a
problem.

Thanks,

C.
