I'm referring to:
ajd at ajd:~/code/skiboot$ gg "opal_call(OPAL_CONSOLE_FLUSH"
core/console.c:opal_call(OPAL_CONSOLE_FLUSH, opal_console_flush, 1);
core/console.c:opal_call(OPAL_CONSOLE_FLUSH, dummy_console_flush, 1);
I realise opal_register() overwrites the handler at runtime, but what
exactly happens with multiple opal_call()s?
This is of course moot as we fix it a few patches later.
