The current fixed physical/virtual mappings for the internal peripherals of the ixp4xx SoC devices is using a virtual address outside of the vmalloc region. This results in kernel warnings like this on the boot console: BUG: mapping for 0xc8000000 at 0xffbeb000 out of vmalloc space BUG: mapping for 0xc4000000 at 0xffbfe000 out of vmalloc space BUG: mapping for 0xc0000000 at 0xffbff000 out of vmalloc space The virtual kernel memory layout lists this for the vmalloc region: ... vmalloc : 0xc2800000 - 0xff000000 ( 968 MB) ... With a little adjustment to the virtual address used we can map these internal devices in the vmalloc region.
