This patch removes logic for wbinvd_on_all_cpus and brings in drm_cache.h. This header has the logic that outputs a warning when wbinvd_on_all_cpus when its being used on a non-x86 platform. Signed-off-by: Michael Cheng <michael.cheng@xxxxxxxxx>
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().
