Date: Wed, 13 Jun 2007 12:03:34 +0200 From: Peter Zijlstra <a.p.zijlstra@...llo.nl> To: linux-kernel@...r.kernel.org, parisc-linux@...ts.parisc-linux.org, linux-mm@...ck.org, linux-arch@...r.kernel.org Cc: Ollie Wild <aaw@...gle.com>, Peter Zijlstra <a.p.zijlstra@...llo.nl>, Andrew Morton <akpm@...l.org>, Ingo Molnar <mingo@...e.hu>, Andi Kleen <ak@...e.de> Subject: [patch 0/3] no MAX_ARG_PAGES -v2 This patch-set aims at removing the current limit on argv+env space aka. 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 from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
