Thanks a lot, Sebastian, excellent work!

I have upgraded about 40 different QA Farm systems (x86: 32-bit, 64-bit, 
single-core, multi-core 2 to 32, single-socket, dual-socket; ARM: 
single-core, multi-core), and they all boot and run without any problem. 
I didn't see any crash of unknown origin so far. Most systems use the 
original kernel besides some unimportant farm patches. Several systems 
have a worst-case latency below 20 microseconds (e.g. 
https://www.osadl.org/?id=1420 and https://www.osadl.org/?id=1805). Even 
Raspberry Pi and BeagleBone-Black work like a charm and have reasonably 
low real-time latency (https://www.osadl.org/?id=1663 and 
https://www.osadl.org/?id=1601), although they still are not 100% 
mainline. It is well conceivable that this or one of the next 3.12.X-rtY 
versions will remind us of the legendary 2.6.33 RT kernel.

Seems that an important milestone is being reached.

Thanks,
	-Carsten.
