+Subject: ata: libata-scsi: ignore reserved bits for REPORT SUPPORTED OPERATION CODES
+
+From: Niklas Cassel <niklas.cassel@wdc.com>
+
+commit 3ef600923521616ebe192c893468ad0424de2afb upstream.
+
+For REPORT SUPPORTED OPERATION CODES command, the service action field is
+defined as bits 0-4 in the second byte in the CDB. Bits 5-7 in the second
+byte are reserved.
+
+Only look at the service action field in the second byte when determining
+if the MAINTENANCE IN opcode is a REPORT SUPPORTED OPERATION CODES command.
+
+This matches how we only look at the service action field in the second
+byte when determining if the SERVICE ACTION IN(16) opcode is a READ
+CAPACITY(16) command (reserved bits 5-7 in the second byte are ignored).

+Subject: kernel/sched: Modify initial boot task idle setup
+
+From: Liam R. Howlett <Liam.Howlett@oracle.com>
+
+commit cff9b2332ab762b7e0586c793c431a8f2ea4db04 upstream.
+
+Initial booting is setting the task flag to idle (PF_IDLE) by the call
+path sched_init() -> init_idle(). Having the task idle and calling
+call_rcu() in kernel/rcu/tiny.c means that TIF_NEED_RESCHED will be
+set. Subsequent calls to any cond_resched() will enable IRQs,
+potentially earlier than the IRQ setup has completed. Recent changes
+have caused just this scenario and IRQs have been enabled early.
+
+This causes a warning later in start_kernel() as interrupts are enabled
+before they are fully set up.
+
+Fix this issue by setting the PF_IDLE flag later in the boot sequence.
+
+Although the boot task was marked as idle since (at least) d80e4fda576d,
+I am not sure that it is wrong to do so. The forced context-switch on
+idle task was introduced in the tiny_rcu update, so I'm going to claim
+this fixes 5f6130fa52ee.
+

+Subject: sched/rt: Fix live lock between select_fallback_rq() and RT push
+
+From: Joel Fernandes (Google) <joel@joelfernandes.org>
+
+commit fc09027786c900368de98d03d40af058bcb01ad9 upstream.
+
+During RCU-boost testing with the TREE03 rcutorture config, I found that
+after a few hours, the machine locks up.
+
+On tracing, I found that there is a live lock happening between 2 CPUs.
+One CPU has an RT task running, while another CPU is being offlined
+which also has an RT task running. During this offlining, all threads
+are migrated. The migration thread is repeatedly scheduled to migrate
+actively running tasks on the CPU being offlined. This results in a live
+lock because select_fallback_rq() keeps picking the CPU that an RT task
+is already running on only to get pushed back to the CPU being offlined.
+
+It is anyway pointless to pick CPUs for pushing tasks to if they are
+being offlined only to get migrated away to somewhere else. This could
+also add unwanted latency to this task.
+
+Fix these issues by not selecting CPUs in RT if they are not 'active'
+for scheduling, using the cpu_active_mask. Other parts in core.c already
+use cpu_active_mask to prevent tasks from being put on CPUs going
+offline.
+
+With this fix I ran the tests for days and could not reproduce the
+hang. Without the patch, I hit it in a few hours.
