drm/i915: Pair va_copy with va_end in i915_error_vprintf

2014-02-22T21:32:26Z

commit 1d2cb9a54abc6e1d239f28f07661366d5662a94a upstream. Each invocation of va_copy() must be matched by a corresponding invocation of va_end() in the same function.

drm/mgag200: fix oops in cursor code.

2014-02-13T21:50:24Z

commit 53dac830537b51df555ba5e7ebb236705b7eaa7c upstream. In some cases we enter the cursor code with file_priv = NULL causing an oops, we also can try to unpin something that isn't pinned, and this is a good fix for it. Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/vmwgfx: Fix regression caused by "drm/ttm: make ttm reservation calls behave like reservation calls"

2014-02-13T21:50:24Z

commit cf5e3413337309050c05e13dcebe85b7194a21e5 upstream. The call to ttm_eu_backoff_reservation() as part of an error path would cause a lock imbalance if the reservation ticket was not initialized. This error is easily triggered from user-space by submitting a bogus command stream.

drm: ast,cirrus,mgag200: use drm_can_sleep

2014-02-13T21:50:24Z

commit f4b4718b61d1d5a7442a4fd6863ea80c3a10e508 upstream. these 3 were checking in_interrupt but we have situations where calling vunmap under this could cause a BUG to be hit in smp_call_function_many. Use the drm_can_sleep macro instead, which should stop this path from been taken in this case. Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/rcar-du: Update plane pitch in .mode_set_base() operation

2014-02-13T21:50:23Z

commit eb86301f293da3c362db729a9f40ddb25755902b upstream. When setting a new frame buffer with the mode set base operation the pitch value might change. Set the hardware plane pitch register at the same time as the plane base address in the rcar_du_plane_update_base() function to make sure the pitch value always matches the frame buffer.
