Ah, wait, I found the tarball you sent for these, and have taken them for 5.4, 5.10, and 5.15 now (the original broke the build.) We still need them for older kernels though, that's still an issue.
Thanks for applying patches. Older kernels ( < 5.4) do not have the patch to fix ("drm/i915: Flush TLBs before releasing backing store"), and they do not support Gen12 AFAIK, so it should be fine.
