The x86-specific wbinvd_on_all_cpus() function is exported through asm/smp.h, causing a build failure in the i915 driver when SMP is disabled:
drivers/gpu/drm/i915/i915_gem.c:1182:2: error: implicit declaration of function 'wbinvd_on_all_cpus' [-Werror,-Wimplicit-function-declaration]
I thought the code was already in i915_gem_pm.c (which included smp.h); it is now. -Chris
