Public bug reported: [Impact] Kernel might fail booting on systems where the physical memory footprint exceeds the size of the linear mapping. The following patches addresses this issue:
[v2,1/2] efi: arm-stub: Correct FDT and initrd allocation rules for arm64 https://patchwork.kernel.org/patch/9565537/ [v2,2/2] efi: arm-stub: Round up FDT allocation to mapping size https://patchwork.kernel.org/patch/9565539 [Testing] These patches were regression tested. Patches were applied to Zesty latest and boots on a KVM instance and on QDF2400 ARM64 Qualcomm server. At this time do not have systems with high memory to test with. [Regression Potential] Changes are confined to ARM architecture, patches apply cleanly to Ubuntu-4.10.0-13.15. Potential for any regression is low. ** Affects: linux (Ubuntu) Importance: Critical Assignee: Manoj Iyer (manjo) Status: New ** Changed in: linux (Ubuntu) Importance: Undecided => Critical ** Description changed: [Impact] - Kernel might fail booting on systems where the physical memory footprint exceeds the - size of the linear mapping.
