[RPi5] Raspbi vs generic-64k ARM64 kernels

[Daniel J Blueman]

I find Ubuntu 24.04.2 LTS works amazingly on the Raspberry Pi 5 16GB
using the default linux-image-raspi metapackage; great work!

Is anyone aware of reasons the 64KB-pagesize ARM64 kernel
(linux-image-generic-64k metapackage) shouldn't work [1]? If none,
I'll log it and start investigating.

Thanks,
  Dan
