Bananymous 1c882ea361 DynamicLoader: Don't print TODOs on PT_GNU_ headers

Bananymous 6542a037df Kernel: Make spinlocks more safe

Bananymous 1bcd1edbf5 Kernel/LibC: Implement basic epoll 
This implementation is on top of inodes instead of fds as linux does it.
If I start finding ports/software that relies on epoll allowing
duplicate inodes, I will do what linux does.

I'm probably missing multiple epoll_notify's which may cause hangs but
the system seems to work fine :dd:
