Thanks for letting me know! I will try for a different solution.

This patch removes logic for wbinvd_on_all_cpus and brings in

Linus has been pretty clear that he won't accept patches that add
macros that works on one arch and warns on others anymore in i915 and
I figure even less so in drm code.
So we shouldn't try to move this out to drm. Instead we should
restrict the wbinvd() inside our driver to integrated and X86 only.
For discrete on all architectures we should be coherent and hence not
be needing wbinvd().
Thanks,
