The cool POSIX kids use clock_gettime() now because it has NANOSECONDS (and different clocks!),
but ANSI C prefers this function.
We can still implement it based on clock_gettime(), we just have to discard the NANOSECONDS.

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 :^)

At some point, this should be done inside LinkedList itself, but we have no such thing as break in for_each().
It's iterate over everything or nothing.
This also requires operator= in Option, might be also added to Result in the future.
