smp now seems to work

+ Had some minor issues with a wraparound of size_t that effectively
  meant that some regions were allocated twice. Also, booting should be
  a bit more reliable now, turned out that the previous iteration of the
  booting was just accidentally working due to the kernel being placed
  'close enough' in RAM to where it was linked to. Fixed by allocating a
  vmem of O1 that maps the kernel to a 2MiB boundary at boot, pretty
  nifty.
