OPAL_BUSY_EVENT from firmware, which causes large scheduling # latencies, up to 50 seconds have been observed here when RTC stops # responding (BMC reboot can do it). # # Fix this by converting it to the standard form OPAL_BUSY loop that # sleeps. # # Fixes: 628daa8d5abf ("powerpc/powernv: Add RTC and NVRAM support plus RTAS fallbacks") # Cc: stable@vger.kernel.org # v3.2+ # Signed-off-by: Nicholas Piggin # Acked-by: Alexandre Belloni #
