From ca9ab10033d190c1ede85fdf456307bdfdabf079 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Sun, 22 Nov 2009 15:40:31 +0000 Subject: [PATCH] drm/i915: Select CONFIG_SHMEM The driver requires shmfs as the backing filesystem to handle the buffer objects, so ensure it is selected if the user chooses to build our driver. Fixes: Bug 14662 - Dell E5500 kernel panic with KMS http://bugzilla.kernel.org/show_bug.cgi?id=14662 The revealing nature of the panic is the NULL function pointer dereference in read_cache_page_async().
