Every other architecture with permanent fixed addresses has FIX_HOLE as the first entry. This seems to be designed as a debugging aid but there are a couple of side effects of not having FIX_HOLE: - If the first fixed address is 0, fix_to_virt -> virt_to_fix triggers a BUG_ON for the virtual address being equal to FIXADDR_TOP - fix_to_virt may return a value outside of FIXADDR_START and FIXADDR_TOP which may look like a bug to a developer. Match up with other architectures and make everything clearer by adding FIX_HOLE. Signed-off-by:
