Subject: [PATCH 2/2] OMAP2420 IO mapping: move IVA mapping virtual address out of vmalloc space
Date: Thu, 03 Dec 2009 01:15:59 -0700 [thread overview]
Message-ID: <20091203081558.1004.57172.stgit@localhost.localdomain> (raw)
In-Reply-To: <20091203081337.1004.51309.stgit@localhost.localdomain>
Commit 10db25fea4c11661070b97832b8cc3d2af495092 causes the following
kernel messages during N800 boot (and presumably all other 2420
boards):
[ 0.000000] BUG: mapping for 0x58000000 at 0xe0000000 overlaps vmalloc space
[ 0.000000] BUG: mapping for 0x59000000 at 0xe1000000 overlaps vmalloc space
[ 0.000000] BUG: mapping for 0x5a000000 at 0xe2000000 overlaps vmalloc space
Fix by remapping the IVA memory areas somewhere outside vmalloc space.
