Matthew stopped maintaining the securelevel patch set, and David
Howells has taken it up under the new name 'lockdown'. This is
taken from:
https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git#efi-lock-down
commits ddb99e118e37f324a4be65a411bb60ae62795cf9..0240fa7c7c948b19d57c0163d57e55296277ff3c
Rebase the three patches not included there (cold boot mitigation,
arm64 SB integration, MTD RAM restrictions).
Update our kconfig for the renaming.
efi_get_secureboot() now returns one of three enumerated values, not
a boolean. We need to either redefine the DT property the same way
(risky unless we also rename it) or squash them into a boolean.
Do the latter.
Remove merged patches and rebase remaining patches.
A portion of the secureboot patches have been upstreamed, but were
changed substantially during review, primarily to avoid code
duplication among arches. I've stripped the patches of the merged
bits and rebased the remainder.

dak currently allows a binary upload to include debug symbol packages
that don't appear in the overrides file or the Binary field of the
changes file, so long as they have the appropriate
'Auto-Built-Package' field and their name matches another binary
package in the upload plus the '-dbgsym' suffix.
For architectures with code signing enabled, our binary uploads never
match this condition as the corresponding binary package has the
'-unsigned' suffix and the debug symbols package does not. Since we
do list the debug symbol packages in the Binary field, they do get
added to the overrides file when accepted through the NEW queue, but
they are automatically pruned from there some time later. Later
uploads then have to go through NEW even though they are not
introducing new binary packages. This would be a big problem for
stable security updates.
For now, move debug symbols back to the main archive with the old
'-dbg' suffix. Keep them enabled for all architectures.
