mm: use vmf->address instead of of vmf->virtual_address

2016-12-15T00:04:09+00:00

Every single user of vmf->virtual_address typed that entry to unsigned long before doing anything with it so the type of virtual_address does not really provide us any additional safety. Just use masked vmf->address which already has the appropriate type. Link: http://lkml.kernel.org/r/1479460644-25076-3-git-send-email-jack@suse.cz Signed-off-by: Jan Kara Acked-by: Kirill A.

drm/prime: Take a ref on the drm_dev when exporting a dma_buf

2016-10-05T13:30:32+00:00

dma_buf may live a long time, longer than the last direct user of the driver. We already hold a reference to the owner module (that prevents the object code from disappearing), but there is no reference to the drm_dev - so the pointers to the driver backend themselves may vanish. v2: Resist temptation to fix the bug in armada_gem.c not setting the correct flags on the exported dma-buf (it should pass the flags through and not be arbitrarily setting O_RDWR). Use a common wrapper for exporting the dmabuf and acquiring the reference to the drm_device.

drm/udl: fix line iterator in damage handling

2016-09-28T03:29:18+00:00

The udl damage handler is supposed to render 'height' lines, but its iterator has an obvious typo that makes it miss most lines if the rectangle does not cover 0/0. Fix the damage handler to correctly render all lines.
