It will completed in the next hours (much faster than the last time).

While the page is completed, you can read about Linux 3.17 in the following sites:
 * LWN Merge window, [http://lwn.net/Articles/607627/ part 1], [http://lwn.net/Articles/608434/ part 2] and [http://lwn.net/Articles/608748/ part 3]

 * firmware loader: allow disabling of udev as firmware loader [http://git.kernel.org/linus/5a1379e8748a5cfa3eb068f812d61bde849ef76c commit]

 * dma-buf: add poll support [http://git.kernel.org/linus/9b495a5887994a6d74d5c261d012083a92b94738 commit]
 * fence: dma-buf cross-device synchronization: A fence can be attached to a buffer which is being filled or consumed by hw, to allow userspace to pass the buffer without waiting to another device. For example, userspace can call page_flip ioctl to display the next frame of graphics after kicking the GPU but while the GPU is still rendering.  The display device sharing the buffer with the GPU would attach a callback to get notified when the GPU's rendering-complete IRQ fires, to update the scan-out address of the display, without having to wake up userspace  [http://git.kernel.org/linus/e941759c74a44d6ac2eed21bb0a38b21fe4559e2 commit]
