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 1/24/2020. Enjoy, -- Steve To build 4.19.94-rt39-rc2 directly, the following patches should be applied: http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.19.tar.xz http://www.kernel.org/pub/linux/kernel/v4.x/patch-4.19.94.xz http://www.kernel.org/pub/linux/kernel/projects/rt/4.19/patch-4.19.94-rt39-rc2.patch.xz You can also build from 4.19.94-rt38 by applying the incremental patch: http://www.kernel.org/pub/linux/kernel/projects/rt/4.19/incr/patch-4.19.94-rt38-rt39-rc2.patch.xz Changes from 4.19.94-rt38: --- Clark Williams (1): thermal/x86_pkg_temp: make pkg_temp_lock a raw spinlock Daniel Wagner (1): lib/smp_processor_id: Adjust check_preemption_disabled() Julien Grall (4): hrtimer: Use READ_ONCE to access timer->base in hrimer_grab_expiry_lock() hrtimer: Don't grab the expiry lock for non-soft hrtimer hrtimer: Prevent using hrtimer_grab_expiry_lock() on migration_base 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 (11): i2c: exynos5: Remove IRQF_ONESHOT i2c: hix5hd2: Remove IRQF_ONESHOT dma-buf: Use seqlock_t instread disabling preemption x86: preempt: Check preemption level before looking at lazy-preempt hrtimer: Add a missing bracket and hide `migration_base' on !SMP posix-timers: Unlock expiry lock in the early return 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 Steven Rostedt (VMware) (1): Linux 4.19.94-rt39-rc2 Thomas Gleixner (1): KVM: arm/arm64: Let the timer expire in hardirq context on RT 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/dma-buf/dma-buf.c | 8 +- drivers/dma-buf/reservation.c | 43 ++--- drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c | 6 +- drivers/gpu/drm/i915/i915_gem.c | 10 +- drivers/i2c/busses/i2c-exynos5.c | 4 +- drivers/i2c/busses/i2c-hix5hd2.c | 3 +- drivers/thermal/x86_pkg_temp_thermal.c | 24 +-- include/linux/cpu.h | 4 - include/linux/reservation.h | 4 +- include/linux/sched.h | 11 +- include/linux/stop_machine.h | 2 + init/init_task.c | 4 + kernel/cpu.c | 103 ++++------ kernel/futex.c | 230 +++++++++++++---------- 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 +- kernel/time/hrtimer.c | 14 +- kernel/time/posix-cpu-timers.c | 4 +- lib/smp_processor_id.c | 7 +- lib/ubsan.c | 64 +++---- localversion-rt | 2 +- mm/kmemleak.c | 72 +++---- virt/kvm/arm/arch_timer.c | 6 +- 30 files changed, 510 insertions(+), 490 deletions(-)
