Oh we don't provide a kernel interface for it, well not "officially", that's not what I meant by using iomap. You -can- use the platform specific _PAGE_ENDIAN to ioremap_flags() but that's very platform specific and it's up to you to know you're doing it on a CPU that supports it :-) Cheers, Ben. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
