Subject: drm/ttm: clean up non-x86 definitions on ttm_page_alloc_dma
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: c7bb1e57e20a7f43b52df183d1a5a1aa936acc2d
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
All non-x86 definitions are moved to ttm_set_memory header, so remove it from
ttm_page_alloc_dma.c.
