But that doesn't look like the issue that the user was complaining
about. Rather, it's that the higher EFI regions are unable to be mapped
because of the user's mem= kernel parameter setting.
However, even though this bug isn't the main focus of the above report,
since people are hitting it (and since the fix is trivial), I agree it's
worth tagging for stable.
