Public bug reported:
[SRU Justification]
== Impact
23.10/Mantic (and newer) kernels are packaged with modules compressed to
save disk space and load time. This will remain unchanged. For
simplifying backports into 22.04/Jammy LTS we need a way to turn this
off when compiling those newer kernels as HWE kernels.
== Fix
Add an option to turn off module compression when packaging the kernel.
This will be unset when compiling Mantic and newer. So there will be no
change there.
== Testcase
Verify that in Mantic the size of the modules package(s) does not
change.
== Regression potential
The compression could be accidentally disabled in newer kernels.
