From: Chris Wilson Date: Sun, 22 Nov 2009 15:40:31 +0000 (+0000) Subject: drm/i915: Select CONFIG_SHMEM X-Git-Tag: v2.6.31.7~52 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2ca6ea590d90073119d1471c79cc6f0df28f4747;p=thirdparty%2Fkernel%2Fstable.git drm/i915: Select CONFIG_SHMEM commit ca9ab10033d190c1ede85fdf456307bdfdabf079 upstream. 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().
