From 51676b14e8cfd5bbabf487f659f11704f17f6d0f Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Sun, 29 Jul 2012 19:18:03 +0200 Subject: Revert "Use broadcast SIPI to startup siblings" This reverts commit 042c1461fb777e583e5de48edf9326e47ee5595f. It turned out that sending IPIs via broadcast doesn't work on Sandybridge. We tried to come up with a solution, but didn't found any so far. So revert the code for now until we have a working solution.
