Daniel Walker d5d8ec895c powerpc/mm: Make mmap_64.c compile on 32bit powerpc ... There appears to be no good reason to keep this as 64bit only. It works on 32bit also, and has checks so that it can work correctly with 32bit binaries on 64bit hardware which is why I think this works. I tested this on qemu using the virtex-ml507 machine type.
