That's a very sensible suggestion, but departs from how we have assigned new numbers up until now: so include/asm-generic/mman-common.h isn't actually where we'd expect to find a Linux-specific MAP_ define. I'd say, yes, do that for now, so as not to hit this conflict while testing in mmotm. But whether it should stay that way, or later the arch/*/include/asm/mman.h's be updated as I'd imagined, I don't know. Arnd, Michael, do you have any views on this?
