| |
2.6.31-stable review patch. If anyone has any objections, please let us know.
------------------ From: Chris Wilson <chris@chris-wilson.co.uk>
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().
