Bug description:
  [Impact]
  Ubuntu is not bootable on various arm64 laptops (HP Envy x2, Asus NovaGo, Lenovo Miix 630 and maybe the Lenovo Yoga C630) because GRUB fails to boot. The reason is that their firmware tries to ensure NX protection flags which it can only do when the code is 4K aligned.

  [Test Case]
  Install and boot Ubuntu on one of the above arm64 laptops.

  [Fix]
  (pending upstream)

  [Regression Risk]
