One other high-level comment: It would be nice to see the arch-independent and x86 portions broken out and explained in their own right, even if they're small patches. It's a bit cruel to make us scroll through a thousand lines of sparc code to see the bits interesting to us. It would also be really nice to see a high-level breakdown explaining what you had to modify, especially since this affects all of the system calls that take a PROT_* argument. The sample code is nice, but it's no substitute for writing it down. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
