Odroid U3 with kernel

I've merged with the odroid-3.8.y branch, and I got a kernel that has reasonable realtime performance on my Odroid U3. I've put the tree (including my config, as arch/arm/configs/odroidu_defconfig) on github.

The U3 isn't without annoyances and the idea of LinuxCNC on ARM isn't free from worries, but I now have a platform dedicated to devloping linuxcnc uspace that draws only 2W when idle, and can build LinuxCNC from clean in about 4 minutes. Not bad!

Tasmania #2

For the second half of our tour around Tasmania, we went to Freycinet National Park, which was absolutely gorgeous. Had a great hike up to view Wineglass Bay, and then visited other bays and areas of the park. We also stayed not to far away at Windsong B&B. We then spent a day on the tiny Maria Island enjoying being away from people and cars. For the last day, we explored the Royal Tasmania Botanical Garden in Hobart.
