My plan was to implement the generic infrastructure and then work to remove the per-arch code for ptdump debugfs where possible. This patch series doesn't actually get that far because I wanted to get some confidence that the general approach would be accepted. > Linus also had some strong opinions in the past on how page walks should > be written. He needs to have a look before we go much further. Fair enough. I'll post the initial work I've done on unifying the x86/arm64 ptdump code - the diffstat is a bit nicer on that - but there's still work to be done so I'm posting just as an RFC. Thanks, Steve
