OMAP2420 IO mapping: move IVA mapping virtual address out of vmalloc space
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.
