Hello Linus, Here's the PR with the patch that gets rid of the misalignment WARN(). The other patch adds an SMBIOS based quirk for Ampere Altra machines. This is the first time we've added such a quirk on arm64, but fortunately, we can just call a EFI protocol to grab the type #1 SMBIOS record when running in the stub, so we don't need all the machinery we have in the kernel proper to parse SMBIOS data. Please pull.
