[OS-BUILD PATCH 0/5] [redhat] enable CONFIG_CMA on aarch64 in ARK as tech-preview

From: David Hildenbrand on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1592 Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2043141 Upstream: RHEL only The above bugzilla is for RHEL9/CS9 and I'll send a MR soon that performs the same changes to CS9. Enable CONFIG_CMA on aarch64 in ARK as we already have in fedora. We did the same change for x86-64 just recently. Move the relevant configs from redhat/configs/fedora to redhat/configs/common. While in tech-preview, we'll require a manual configuration of cma on the kernel command line -- we will default to "cma=0". Once e.g., "cma=64M" has been specified, cma_activate_area() will call mark_tech_preview("CMA"), essentially tainting the kernel. Once no longer in tech-preview, we can enable CMA as default by e.g., similarly defaulting to "cma=64M". The real change is preceded by some cleanups around CMA configs.
