When creating a dumb buffer object using the DRM_IOCTL_MODE_CREATE_DUMB IOCTL, only the width, height, bpp and flags parameters are inputs. The caller is not guaranteed to zero out or set handle, pitch and size, so the driver must not treat these values as possible inputs. Fixes a bug where running the Weston compositor on Tegra DRM would cause an attempt to allocate a 3 GiB framebuffer to be allocated.

That's _one_ way of looking at it ] This pull is missing nouveau, Ben has been stuck trying to track down a very longstanding bug that revealed itself due to some other changes. I've asked him to send you a direct pull request for nouveau once he cleans things up. I'm away until Monday so don't want to delay things, you can make a decision on that when he sends it, I have my phone so I can ack things just not really merge much. It has one trivial conflict with your tree in armada_drv.c, and also the pull request contains some component changes that are already in your tree, the base tree from Russell went via Greg's tree already, but some stuff still shows up in here that doesn't when I merge my tree into yours. Otherwise all pretty standard graphics fare, one new driver and changes all over the place.

Tegra114 and Tegra124 increased the alignment to 64 bytes. Introduce a parameter to specify the alignment requirements for each display controller and round up the pitch of newly allocated framebuffers appropriately.

Add support for these by moving the internal representation into a structure rather than a simple flag.
