Compile fixes for RHEL 9.3 kernels

The ranges were build tested on RHEL9.2 (5.14.0-284.11.1), RHEL9.3
(5.14.0-362.8.1) and RHEL8.9 (4.18.0-513.11.1).

This disables the kmem and compaction modules.  I don't believe getting
these to compile will be easy, as the required struct declarations are
in vmlinux.h, and haven't been moved into mm/internal.h and mm/slab.h in
the RHEL sources.
