a good number of generic bits (generic irq subsystem, preemption fixes/enhancements, lock initializer cleanups, and tons of fixes found in -RT) are upstream or in -mm already, but the core PREEMPT_RT stuff is still under development and thus not ready for upstream. I'm constantly sending independent bits (fixes or orthogonal improvements) that show up in -RT towards upstream as well. [-RT would be a 1MB unmaintainable patch otherwise.]
