Subject: [ANNOUNCE] v5.2.9-rt3

Dear RT folks!

I'm pleased to announce the v5.2.9-rt3 patch set. 

Changes since v5.2.9-rt2:

  - The exynos5 i2c controller disabled IRQ threading as reported by
    Benjamin Rouxel. The hix5hd2 i2c controller did the same.

  - A timer related to the deadline scheduler now fires in hard-irq
    context. Patch by Juri Lelli.

  - A lock used the x86's thermal exception uses a raw_spinlock_t. Patch
    by Clark Williams.

  - The DMA-reservation code is using now a sequence lock instead a
    sequence counter. Yann Collette reported warnings from that area
    with an AMD GPU.

  - Two kvm related timer on arm64 expire now hard-irq context. Reported
    by Julien Grall, patched by Thomas Gleixner.

  - Lazy preemption was broken in a case on arm64, reported by Paul
    Thomas. While investigating another lazy-preempt bug was fixed on
    arm64 and x86.

Known issues
     - rcutorture is currently broken on -RT. Reported by Juri Lelli.

The delta patch against v5.2.9-rt2 is appended below and can be found here:
