From 0054e14793e585ec0d8e95e3d7b82cbf1a684af8 Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Sat, 14 Feb 2009 22:22:39 +0200 Subject: drm_compat: remove kmap_atomic_prot_pfn() This function is unused, and yet creates build problems: the symbol init_mm is not exported by the latest -rc kernels and I don't believe it ever will be. Even CONFIG_UNUSED_SYMBOLS does not provide it anymore. If this function is needed in the future, it needs to be reinvented in any case. So remove it.
