+Subject: [PATCH] Explain why we want SECOND to kick.
+ We do not mask the SECOND interrupt to make sure that we get
+ a interrupt at the beginning. We use this for the coldplug_done
+ initisalisation.
+ So pcf->flags and INT1M is out of sync at the beginning but after the
+ first SECOND interrupt it will be put into sync.
