Right, this shouldn't be a problem because we do in fact allocate space
using the EFI boottime services in efi_relocate_kernel(), taking the
alignment into account, and then perform the kernel image copy.
I still think your change makes sense, I'm just inclined to delete the
paragraph referring to the corruption bug (which we've established
doesn't exist).
Do we still have a bug?
Ah; that was the old e-mail thread I couldn't find!
You are right; this change can safely be reverted. Sorry for the noise.
