If anyone has any objections, please let us know. ------------------ From: Chris Wilson commit ca9ab10033d190c1ede85fdf456307bdfdabf079 upstream.

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().
