MAX_ARG_PAGES. The new mm is created before the binfmt code runs, the stack is placed at the highest address supported by that architecture. The argv+env data is then copied from the old mm into the new mm (which is inactive at that time - this introduces some cache coherency issues). Then we run the binfmt code, which will compute the final stack address. The existing stack will be moved downwards (or upwards on PA-RISC) to the desired place. This 'trick' heavily relies on the MMU, so for no-MMU archs we stay with the old approach. --- Plenty of changes all around, changes listed in the individual patches. We hope to have addressed all issues raised. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
