The Rockship DRM GEM code uses vmap()/vunmap() so vmalloc header must be
included to avoid warnings like (on IA64, compile tested):

    drivers/gpu/drm/rockchip/rockchip_drm_gem.c: In function ‘rockchip_gem_alloc_iommu’:
    drivers/gpu/drm/rockchip/rockchip_drm_gem.c:134:20: error:
        implicit declaration of function ‘vmap’ [-Werror=implicit-function-declaration]
