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:

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

config RCU_BOOST
	bool "Enable RCU priority boosting"
	depends on RT_MUTEXES && PREEMPT_RCU && RCU_EXPERT
	default y if PREEMPT_RT_FULL
