[ANNOUNCE] v4.19.23-rt14v4.19.23-rt14-patches

Dear RT folks!

I'm pleased to announce the v4.19.23-rt14 patch set.

Changes since v4.19.23-rt13:

  - Use the specified preempt mask in should_resched() on x86. Otherwise
    a scheduling opportunity of non RT tasks could be missed.

  - Preserve the task state in cpu_chill()

  - Add two more cases to consider before warning about pending
    softirqs.

Known issues
     - A warning triggered in "rcu_note_context_switch" originated from
       SyS_timer_gettime(). The issue was always there, it is now
       visible. Reported by Grygorii Strashko and Daniel Wagner.

The delta patch against v4.19.23-rt13 is appended below and can be found here:

     https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.19/incr/patch-4.19.23-rt13-rt14.patch.xz

You can get this release via the git tree at:

    git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v4.19.23-rt14

+From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+Date: Tue, 19 Feb 2019 16:59:15 +0100
+Subject: [PATCH] hrtimer: Don't lose state in cpu_chill()
+
+In cpu_chill() the state is set to TASK_UNINTERRUPTIBLE and a timer is
+programmed. On return the state is always TASK_RUNNING which means we
+lose the state if it was something other than RUNNING. Also
+set_current_state() sets ->task_state_change to within cpu_chill() which
+is not expected.
+
+Save the task state on entry and restore it on return. Simply set the
+state in order to avoid updating ->task_state_change.
+

+Subject: [PATCH] softirq: Avoid "local_softirq_pending" messages if
+ ksoftirqd is blocked
+
+If the ksoftirqd thread has a softirq pending and is blocked on the
+`local_softirq_locks' lock then softirq_check_pending_idle() won't
+complain because the "lock owner" will mask away this softirq from the
+mask of pending softirqs.
+If ksoftirqd has an additional softirq pending then it won't be masked
+out because we never look at ksoftirqd's mask.
+
+If there are still pending softirqs while going to idle check
+ksoftirqd's and ktimersfotd's mask before complaining about unhandled
+softirqs.

+Subject: [PATCH] softirq: Avoid "local_softirq_pending" messages if task
+ is in cpu_chill()
+
+If the softirq thread enters cpu_chill() then ->state is UNINTERRUPTIBLE
+and has no ->pi_blocked_on set and so its mask is not taken into account.
+
+->sleeping_lock is increased by cpu_chill() since it is also requried to
+avoid a splat by RCU in case cpu_chill() is used while a RCU-read lock
+is held. Use the same mechanism for the softirq-pending check.

+Subject: [PATCH] x86: lazy-preempt: properly check against preempt-mask
+
+should_resched() should check against preempt_offset after unmasking the
+need-resched-bit. Otherwise should_resched() won't work for
+preempt_offset != 0 and lazy-preempt set.
