If you're not already using it, you might find easier to work from the github Mickaël Salaün has set up, something along those lines: cd linux-2.6 git remote add linux-grsecurity https://github.com/linux-scraping/linux-grsecurity.git git fetch linux-grsecurity git checkout -b grsecurity-pax-refcount-split v4.2.5 git checkout -p linux-grsecurity -- $(git grep -l PAX_REFCOUNT linux-grsecurity/grsec-4.2) Which will drop you into a sub-shell where you can pick relevant hunks. Then you can repeat the last line replacing PAX_REFCOUNT with any new symbols that you've picked on the way. Quentin
