[J][linux-signed-uc22][PATCH 0/5] Unjam kernel snaps versions

[Dimitri John Ledkov]

swm expects pc-kernel snaps on all arches to have the version number
as is generated from src:linux{-signed}-uc22 (enforced via tracker,
checking deb source versions, git tag, snapstore version). Previously
this was simply hardcoded in snapcraft.yaml, but to use adopt-info
style snapcraft.yaml we should be able to derive the correct version
based on the versions of debs one vendors.

To achieve this, lets add linux-image-uc22-generic on armhf/arm64,
which simply depend on the right abi vmlinuz package.

Also since the linux-image-uc22-generic now becomes a pseudo
meta-package which pulls in all the right deps on all the right
arches, add stamp files to it to indicate if it is expected to be
snapped as a kernel.efi or as a vmlinuz kernel snap. Note that soon we
may be able to switch arm64 to kernel.efi style packaging.

Separatly in ~Kernel, it was reported that adopt-info style packaging
managed to vender a newer spin of nvidia modules against -100- abi,
whilst the rest of kernel & modules were still on -99- abi. By adding
abi encoded package dependenices here, snapcraft.yaml can correctly
stage the right abi of everything (kernel, modules, nvidia drivers).

Once this is in place, simplications can be done in pc-kernel
snapcraft.yaml to "simply" stage linux-image-uc22-generic on all
arches.

Dimitri John Ledkov (5):
  debian/control: explicitely declare only amd64 as UEFI signed
  debian/control.stub: introduce unsigned packages on arm64 armhf
  debian/control.stub: add arm64 linux-image-uc22-lowlatency
  debian: provide stampfile of UC22 kernel image type
  debian/control.stub: depend on abi specific nvidia objects and
    signatures
