[Impact]

Since a while, our linux kernel packages also build a 64k page-size kernel variant alongside the regular generic 4k ones for arm64. We had requests coming from various places on making it easier for people to get an ubuntu-server installation with this kernel variant. After many discussions, it has been decided that for now - for noble and jammy - we would ideally want a new image with this kernel as default. The naming has been decided to be 'largemem', for environments with large memory requirements.

[Test Case]

Once package accepted into proposed, build an arm64+largemem ubuntu-server daily-live image and make sure the image builds fine (and gets published on cdimage). Download the image and confirm that the kernel shipped (and offered) are the 64k variants (generic, hwe - if available).

[Regression Potential]

Not much regression potential, but these changes could break other image builds, resulting with build failures. Also, rather impossible, but the changes could also affect the kernels shipped with other server images.
