Anything that implements POSIX should also be where POSIX defines
it to be, otherwise it would be pretty useless lol

piss off capitalism
...
Ardix is being relicensed to GPL v3 or later. I have no idea whether you
can just do this if you feel like it or if it has any consequences, but
i kinda don't really care that much about it. Any changes made after
this commit will definitely fall under the GPL though, and considering
that only few things are really working yet anyways this is good enough
for me.

Don't ask how or why, i'm just glad it works now.

sched: properly disable the watchdog

I have no idea what the FUCK the Engineers at ARM were thinking when
they decided to disable EVERY SINGLE FUCKING CPU COMPONENT on system
reset, except the FUCKING WATCHDOG. But this change will prevent the
system from randomly firing a watchdog reset.
