continuous-integration/drone/push Build is passing
This removes a bunch of casts between pid_t and u64, and makes more sense since pid_t is literally the data type for process IDs.

kernel: Don't create a new kernel stack on exec()
...
continuous-integration/drone/push Build is passing
The old one was not getting freed, creating a memory leak every exec(),
which can get huge over time.
Plus, there was no need for a new stack.
And we couldn't just free the old one, since sys_execve() runs on the old stack...

This ends up being init's directory, which is fine when init's directory doesn't change...
but a little less fine when the init process calls exec()...
which is what it does in the new configuration I'm testing...

continuous-integration/drone/push Build is passing
This is a more appropriate name now that it does more stuff than allocate virtual memory.
To be fair, the name was a bit awkward anyway. Should have been UserVMAllocator I guess.
