(Its Easter and so > the europeans may be off for awhile) Yup, for sure. It's also interesting how much code ppc64 removed when they did this: http://lists.ozlabs.org/pipermail/linuxppc64-dev/2005-November/006646.html Please cc me on patches. Or, if nobody else was planning on doing it, I can take a stab at doing SPARSEMEM on one of the arches. I won't be able to _run_ it outside of qemu, but it might be quicker than someone starting from scratch. Was it really just m68k and parisc that need immediate attention? -- Dave -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
