Sorry Andrea, that simply is impractical. The first thing Andrew's patch series does is include linux-next, therefore every THP and MM patch in his series is against linux-next. So there are already dependencies in there on the pmd_pgprot() bits and I already did the implementation for sparc64 so that's what I'm submitting against. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
