From 88d3c5010a207c651d1940856d0d26935434e3c2 Mon Sep 17 00:00:00 2001 From: Holger Freyther Date: Tue, 13 May 2008 18:53:40 +0100 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.
