From a915249fa1e0a59e9a893cd335fd31af39b01bde Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 21 Jul 2011 01:42:58 +0200 Subject: [PATCH] PPC: E500: Generate IRQ lines for many CPUs Now that we can generate multiple envs for all our virtual CPUs, we also need to tell the MPIC that we have multiple CPUs connected and connect them all to the respective virtual interrupt lines.
