Integrating the latest 4.19-rt to the preempt-rt branches, the -rt
release announcements summarize the changes:
Changes since v4.19.25-rt15:
- The "preserve task state" change in cpu_chill() in the previous
release is responsible for missing a wake up. Reported by Mike
Galbraith.
- The x86-32 lazy preempt code was broken. Reported by Andri Yngvason.
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.
