From d8f1bd2ffcce6af1ace4f1efb327765144aa0755 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Thu, 26 Jul 2012 17:44:12 +0200 Subject: [PATCH] bcma: fix regression in interrupt assignment on mips MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The wrong interrupts where assigned to the cores in bcma_core_mips_init(). This caused at least my serial console not to response to any input. This was caused by this patch which changed the order of the cores in the list: commit c334e25c9f3a95f2bd6b79fedc5170f17245b1c7 Author: Rafał Miłecki Date: Wed Jul 11 12:37:00 2012 +0200 bcma: add new cores at the end of list This should be fixed properly later so that the correct interrupt numbers are assigned to the cores independently from the ordering of the list. This patch restores the old behavior again. I will look into the problem more deeply later. I also changed the order of the list with the cores and their assigned interrupt number which gets printed to the log. Now they are printed in the same order like all the other lists of cores and like it was done before the patch which changed the order. Signed-off-by: Hauke Mehrtens Signed-off-by: John W.
