Please scream at me if I messed something up. Please test the patches too. The -rc release will be uploaded to kernel.org and will be deleted when the final release is out. This is just a review release (or release candidate). The pre-releases will not be pushed to the git repository, only the final release is. If all goes well, this patch will be converted to the next main release on 2020-03-05. To build 4.14.170-rt75-rc2 directly, the following patches should be applied: https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.14.tar.xz https://www.kernel.org/pub/linux/kernel/v4.x/patch-4.14.170.xz https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/patch-4.14.170-rt75-rc2.patch.xz You can also build from 4.14.170-rt74 by applying the incremental patch: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/incr/patch-4.14.170-rt74-rt75-rc2.patch.xz Enjoy, -- Tom Daniel Wagner (1): lib/smp_processor_id: Adjust check_preemption_disabled() Joe Korty (1): Fix wrong-variable use in irq_set_affinity_notifier Julien Grall (1): lib/ubsan: Don't seralize UBSAN report Juri Lelli (1): sched/deadline: Ensure inactive_timer runs in hardirq context Liu Haitao (1): kmemleak: Change the lock of kmemleak_object to raw_spinlock_t Peter Zijlstra (1): locking/rtmutex: Clean ->pi_blocked_on in the error case Scott Wood (7): sched: migrate_dis/enable: Use sleeping_lock…() to annotate sleeping points sched: __set_cpus_allowed_ptr: Check cpus_mask, not cpus_ptr sched: Remove dead __migrate_disabled() check sched: migrate disable: Protect cpus_ptr with lock sched: migrate_enable: Use select_fallback_rq() sched: Lazy migrate_disable processing sched: migrate_enable: Use stop_one_cpu_nowait() Sebastian Andrzej Siewior (8): i2c: exynos5: Remove IRQF_ONESHOT i2c: hix5hd2: Remove IRQF_ONESHOT x86: preempt: Check preemption level before looking at lazy-preempt futex: Make the futex_hash_bucket spinlock_t again and bring back its old state Revert "ARM: Initialize split page table locks for vector page" locking: Make spinlock_t and rwlock_t a RCU section on RT sched/core: migrate_enable() must access takedown_cpu_task on !HOTPLUG_CPU sched: migrate_enable: Busy loop until the migration request is completed Tom Zanussi (1): Linux 4.14.170-rt75-rc2 Waiman Long (1): lib/smp_processor_id: Don't use cpumask_equal() arch/arm/kernel/process.c | 24 ---- arch/x86/include/asm/preempt.h | 2 + drivers/i2c/busses/i2c-exynos5.c | 4 +- drivers/i2c/busses/i2c-hix5hd2.c | 3 +- include/linux/cpu.h | 4 - include/linux/init_task.h | 9 ++ include/linux/sched.h | 11 +- include/linux/stop_machine.h | 2 + kernel/cpu.c | 103 +++++++---------- kernel/futex.c | 231 ++++++++++++++++++++++----------------- kernel/irq/manage.c | 2 +- kernel/locking/rtmutex.c | 114 +++++++++++++++---- kernel/locking/rtmutex_common.h | 3 + kernel/locking/rwlock-rt.c | 6 + kernel/sched/core.c | 211 +++++++++++++++-------------------- kernel/sched/deadline.c | 4 +- kernel/sched/sched.h | 4 + kernel/stop_machine.c | 7 +- lib/smp_processor_id.c | 7 +- lib/ubsan.c | 76 +++++-------- localversion-rt | 2 +- mm/kmemleak.c | 72 ++++++------ 22 files changed, 461 insertions(+), 440 deletions(-)
