From: Matheus Ferst <matheus.fe...@eldorado.org.br> The code in linux-user/ppc/cpu_loop.c expects POWERPC_EXCP_PRIV exception with error POWERPC_EXCP_PRIV_OPC or POWERPC_EXCP_PRIV_REG, while POWERPC_EXCP_INVAL_SPR is expected in POWERPC_EXCP_INVAL exceptions. This mismatch caused an EXCP_DUMP with the message "Unknown privilege violation (03)", as seen in [1].
