From: Arnd Bergmann <arnd@xxxxxxxx>
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]
Include that header file explicitly.
Fixes: 30d2bfd09383 ("drm/i915/gem: Almagamate clflushes on freeze")
