A patch to remove VM_EXEC from VM_DATA_DEFAULT_FLAGS for MIPS has been submitted to me with the primary motivation for this change being some performance improvment. In other words, the patch would remove execute permission from a process brk area. It's however unclear to me how much software wreckage would result from such a change, even if the execute permission for the stack area remains unchanged.
So, what would break? Thanks, Ralf -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
