Subject: [PATCH 0/3] Silence "OPAL called with invalid token" errors

If OPAL firmware is called with an invalid token, that is, one that
the current running firmware does not support, it dumps an error into
its log. For three calls we were making in Linux, we were not adequately
checking that the current firmware supported them, so could get
this warning spuriously.

Stewart Smith (3):
  powerpc/powernv: only register log if OPAL supports doing so
  powerpc/powernv: only call OPAL_ELOG_RESEND if firmware supports it
  powerpc/powernv: only call OPAL_RESEND_DUMP if firmware supports it
