Andreas Kling 952bb95baa Kernel: Enable SMAP protection during the execve() syscall ...

The userspace execve() wrapper now measures all the strings and puts
them in a neat and tidy structure on the stack.

This way we know exactly how much to copy in the kernel, and we don't
have to use the SMAP-violating validate_read_str(). :^)
