This value is not needed if we use correctly the MSR[IP] bit. excp_prefix is always 0x00000000, except when the MSR[IP] bit is implemented and set to 1, in that case excp_prefix is 0xfff00000. The handling of MSR[IP] was already implemented but not used at reset because the value of env->msr was changed "manually". The patch uses the function hreg_store_msr() to set env->msr, this ensures a good handling of MSR[IP] at reset, and therefore a good value for excp_prefix.
