mprotect(): Validate the entire range to protect is in userspace memory
...
Before this patch, sys_mprotect() only validated the starting address.
This was as bad as it sounds, in fact it let me write a fun exploit
using it.
Now, this exploit is no longer possible.
This patch is probably not relevant, since this branch will be gone in
the future, as soon as restart gets merged into main.
I made it anyways :^)
