It's not really split up, and it's kind of a huge patch because it tries to tackle a lot of things at once. Unfortunately, I'm having a hard time finding good clean places to break things apart. Furthermore, I know 100% that it is not complete on PPC32 yet, and it almost certainly does not build on PPC64 yet either. These are the only files in arch/powerpc/ which have known-incorrect references to L1_CACHE_* variables: arch/powerpc/lib/copy_32.S arch/powerpc/kernel/misc_32.S Unfortunately, I've been staring at PPC asm for long enough that I have a migraine headache and I'm going to have to stop here for now. If somebody else wants to tackle fixing up the 32-bit copy_page() and __copy_tofrom_user() routines it would be highly appreciated.
