powerpc: Copy down exception vectors after feature fixups
commit d715e433b7ad19c02fc4becf0d5e9a59f97925de upstream. kdump fails because we try to execute an HV only instruction. Feature fixups are being applied after we copy the exception vectors down to 0 so they miss out on any updates. We have always had this issue but it only became critical in v3.0 when we added CFAR support (breaks POWER5) and v3.1 when we added POWERNV (breaks everyone).
