Dear RT folks!

I'm pleased to announce the v4.4-rc6-rt1 patch set. I tested it on my
AMD A10, 64bit. Nothing exploded so far, filesystem is still there.
I haven't tested it on anything else. Before someone asks: this does not
mean it does *not* work on ARM I simply did not try it.

If you are brave then download it, install it and have fun. If something
breaks, please report it. If your machine starts blinking like a
christmas tree while using the patch then *please* send a photo.

Changes since v4.1.15-rt17:
- rebase to v4.4-rc6

Known issues (inherited from v4.1-RT):
- bcache stays disabled

- CPU hotplug is not better than before

- The netlink_release() OOPS, reported by Clark, is still on the
list, but unsolved due to lack of information

- Christoph Mathys reported a stall in cgroup locking code while using
Linux containers.

You can get this release via the git tree at:

git:// v4.4-rc6-rt1

Additional note: RCU_BOOST now depends on RCU_EXPERT, so commit
3da4cab "rcu: make RCU_BOOST default on RT" is nop now.
