I'm guessing _tlbil_pid is never called, as it will clobber the stack pointer. Should probably just point both function names at the same implementation, since PID-specific invalidation isn't supported on non-tlbilx cores. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
