From 95d449ad4de79dd32b1705b8a4d3550f1e9081e3 Mon Sep 17 00:00:00 2001 From: Marian Balakowicz Date: Tue, 13 May 2008 15:53:29 +0200 Subject: Avoid initrd and logbuffer area overlaps Add logbuffer to reserved LMB areas to prevent initrd allocation from overlaping with it. Make sure to use correct logbuffer base address.
