Bug description:
  [Impact]
  * New kernel broke completely old and current vbox in xenial/artful, + security issues (meltdown,spectre)
  * VM not able to start, 3d not working
  [Test Case]
  * Install 16.04 or 17.10 in a VM, Update or install the hwe stack, reboot, panic

  [Regression Potential]
  * This is the second round of minor updates, since cherry-picking is impossible, and less tested by upstream/debian/me.
  No regressions when we moved 5.0.18 to 5.0.40

  The jump 5.0.40 -> 5.1.32 is bigger, but since 5.0.x is EOL upstream,
  and with a lot of security issues, we should try to get the move in
  Xenial, to make vbox continue working.

  5.2 can't build there, because of a lot of qtbase issues, so sticking
  with 5.1 is the only viable solution we found over the last 4 months

  For this reason, we need a new kbuild too

  [Other Info]
  This is a spin-off of bug 1729568. With Kernel 4.13 (from linux-generic-hwe-16.04-edge), the host system freezes completely when starting a VM using VirtualBox. A black boot window pops up right before the freeze.
