[Bug 1812317] Re: grub is prevented from booting on UEFI Arm64 Laptops - requires 4k aligned headers

[dann frazier]

** Description changed:

- This will end up as an SRU request to patch grub with 4k aligned headers
- to allow amr64 UEFI laptops to boot.
+ [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.
  
- See https://www.mail-archive.com/grub-devel@gnu.org/msg28224.html and
- related patch set (hopefully all approved when this bug is reviewed).
+ [Test Case]
+ Install and boot Ubuntu on one of the above arm64 laptops.
  
- Without these changes booting grub on the Arm64 Snapdragon 835 laptop
- platforms fail. If this can make it into 19.04 and the next 18.04.X that
- would be most appreciated. Impacts the HP Envy x2, Asus NovaGo, Lenovo
- Miix 630 and maybe the Lenovo Yoga C630 64-bit Armv8-A laptops.
+ [Fix]
+ (pending upstream)
+ 
+ [Regression Risk]

+ 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.
