[ANNOUNCE] v4.11.12-rt15v4.11.12-rt15-patches

Dear RT folks!

I'm pleased to announce the v4.11.12-rt15 patch set.

Changes since v4.11.12-rt14:

  - Programmed wake ups (nanosleep, clock_nanosleep, …) by a task with
    RT priority will still be carried out in the hardirq context
    (nothing changes). If it is programmed by task with a normal
    priority then the wake up will be carried out in the softirq
    context via the ktimersoftd thread.
    The advantage is that multiple wake ups of non-RT tasks won't
    disturb the RT task. Reported by Gratian Crisan.

  - Paul Gortmaker reported splat during boot when TSC (on x86) becomes
    unstable and kernel switches to an alternative. This has been fixed
    by cherry-picking a patch from upstream.

  - After the hrtimer rework, certain wake ups (like those programmed in
    the past using the softirq context) won't fire. Reported by Mike
    Galbraith, patched by Anna-Maria Gleixner.

  - After the hrtimer rework, wake ups using CLOCK_REALTIME and a
    relative delay were affected by clock_settime() (they should have
    not been). Reported by Mike Galbraith.
