The x86 low-level cache management operations are declared in
asm/smp.h, so drivers that call into this code need to include
the header:

drivers/gpu/drm/i915/gem/i915_gem_dmabuf.c:248:3: error: implicit declaration of function 'wbinvd_on_all_cpus' [-Werror,-Wimplicit-function-declaration]
                wbinvd_on_all_cpus();
                ^
