+Subject: nouveau: interface changes for 0.0.16 DRM
+
+This commit encompasses the changes necessary to run on top of the 0.0.16
+nouveau interface, additional APIs to support the new features of the
+interface, as well as code from Luca Barbieri to improve the pushbuf
+interface, which just happens to break nouveau's libdrm ABI so was delayed
+until now.
+
+API changes as a result of 0.0.16 DRM interface:
+
+1. No more bo_pin()/bo_unpin(), these were only there for UMS and we no
+   longer support it.
+
+2. Any random nouveau_bo can be submitted to the GPU as a push buffer.
+
+3. Relocations can be applied on any nouveau_bo
+
+This patch changes the pushbuffer ABI to:
+
+1. No longer use/expose nouveau_pushbuffer. Everything is directly
+   in nouveau_channel. This saves the extra "pushbuf" pointer dereference.
+
+2. Use cur/end pointers instead of tracking the remaining size.
+   Pushing data now only needs to alter cur and not both cur and remaining.
+
+The goal is to make the *_RING macros faster and make the interface simpler
+and cleaner in the process.
+
+The *_RING APIs are unchanged, but those are inlined and the ABI is changed.
+
+Also, anything accessing pushbuf->remaining instead of using AVAIL_RING
+will need to be fixed.
