I guess it depends on the kernel config, but it reported: error: implicit declaration of function 'wbinvd_on_all_cpus' AFAIK it's the missing <asm/smp.h>, the CONFIG_X86 thing is just for good measure.

Hmm it looks like we have this in -fixes (and in -gt) while Linus has explicitly thrown it out (see https://lists.freedesktop.org/archives/dri-devel/2021-November/330928.html). End result is that now we have a different Kernel Test Robot warning ("asm/smp.h is included more than once."). So we need to fish out "drm/i915/dmabuf: fix broken build" out from fixes with a revert or what?

wbinvd_on_all_cpus() is only defined on x86 it seems, plus we need to include asm/smp.h here.
