Subject: [PATCH] drm/i915/gem: fix non-SMP build failure
Date: Mon, 25 Jan 2021 13:25:34 +0100
Message-ID: <20210125122542.4144849-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

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")
