Kernel, libc: Add support for providing a status code to exit()
...
The exit() libc function already accepted an integer, but didn't pass it on to the kernel since we had no mechanism for it to do that.
Now, the kernel stores a task's exit status to display it later (and in the future, return it to userspace via wait()/waitpid())

Add mmap and munmap syscalls, and thus, add malloc and free to libc!! (yet again, thanks to the wonderful liballoc)
