[Impact]
Recent kernels emit the following error message when booting on arm64 platforms:

  EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k boundary

While this doesn't appear to cause any functional issues - and indeed, the kernel commit that added the error[*] says "We can deal with this, but let's check for this condition anyway", it is still likely to cause user concern.

[Test Case]
Boot a recent kernel on an EFI-basedarm64 system (impish will do, but the kernel patch is also hitting kernels in older releases). This message will be emitted after GRUB execs the kernel EFI stub.
