Thanks Alexei for taking it. Me and Lorenzo were discussing that not
having this causes incorrect behavior for apps using map-in-map for
this. So I CC'd stable as well.

Subject: [PATCH] ARM: dts: exynos: Disable pull control for MAX8997 interrupts
on Origen
PMIC_IRQB and PMIC_KEYINB lines on Exynos4210-based Origen board have
external pull-up resistors, so disable any pull control for those lines
in respective pin controller node. This fixes support for MAX8997
interrupts and enables operation of wakeup from MAX8997 RTC alarm.

We reproducibly observe cache line starvation on a Core2Duo E6850 (2
cores), a i5-6400 SKL (4 cores) and on a NXP LS2044A ARM Cortex-A72 (4
cores).
The problem can be triggered with a v4.9-RT kernel by starting
cyclictest -S -p98 -m -i2000 -b 200
and as "load"
stress-ng --ptrace 4
The reported maximal latency is usually less than 60us. If the problem
triggers then values around 400us, 800us or even more are reported. The
upperlimit is the -i parameter.
Reproduction with 4.9-RT is almost immediate on Core2Duo, ARM64 and SKL,
but it took 7.5 hours to trigger on v4.14-RT on the Core2Duo.
Instrumentation show always the picture:
CPU0 CPU1

*IRQ* <lock acquired>
In the error case we observe that the while() loop is repeated more than
5000 times which indicates that the pi_lock can be acquired. CPU1 on the
other side does not make progress waiting for the same lock with interrupts
disabled.
This continues until an IRQ hits CPU0. Once CPU0 starts processing the IRQ
the other CPU is able to acquire pi_lock and the situation relaxes.

Backporting all qspinlock related patches is very likely to introduce
regressions on v4.4. Therefore, the recommended solution by Peter and

Thomas suggest following plan for fixing the issues on the varous
stable trees:
4.4: Trivial by switching back to ticket locks.
4.9: Decide whether bringing back ticket locks or backporting all qrlock
fixes. Sebastian has done the latter already and it's probably the
right solution
4.14:
4.18: Backporting the qrlock fixes
4.19: Either the fix ends up in 4.19 final or it needs to be backported

Subject: [PATCH] acpi, nfit: Fix Address Range Scrub completion tracking
The Address Range Scrub implementation tried to skip running scrubs
against ranges that were already scrubbed by the BIOS. Unfortunately
that support also resulted in early scrub completions as evidenced by
this debug output from nfit_test:
nd_region region9: ARS: range 1 short complete
nd_region region3: ARS: range 1 short complete
nd_region region4: ARS: range 2 ARS start (0)
nd_region region4: ARS: range 2 short complete
...i.e. completions without any indications that the scrub was started.
This state of affairs was hard to see in the code due to the
proliferation of state bits and mistakenly trying to track done state
per-range when the completion is a global property of the bus.
So, kill the four ARS state bits (ARS_REQ, ARS_REQ_REDO, ARS_DONE, and
ARS_SHORT), and replace them with just 2 request flags ARS_REQ_SHORT and
ARS_REQ_LONG. The implementation will still complete and reap the
results of BIOS initiated ARS, but it will not attempt to use that
information to affect the completion status of scrubbing the ranges from
a Linux perspective.
Instead, try to synchronously run a short ARS per range at init time and
schedule a long scrub in the background. If ARS is busy with an ARS
request, schedule both a short and a long scrub for when ARS returns to
idle. This logic also satisfies the intent of what ARS_REQ_REDO was
trying to achieve. The new rule is that the REQ flag stays set until the
next successful ars_start() for that range.
With the new policy that the REQ flags are not cleared until the next
start, the implementation no longer loses requests as can be seen from
the following log:
nd_region region3: ARS: range 1 ARS start short (0)
nd_region region9: ARS: range 1 ARS start short (0)
nd_region region3: ARS: range 1 complete
nd_region region4: ARS: range 2 ARS start short (0)
nd_region region9: ARS: range 1 complete
nd_region region9: ARS: range 1 ARS start long (0)
nd_region region4: ARS: range 2 complete
nd_region region3: ARS: range 1 ARS start long (0)
nd_region region9: ARS: range 1 complete
nd_region region3: ARS: range 1 complete
nd_region region4: ARS: range 2 ARS start long (0)
nd_region region4: ARS: range 2 complete
...note that the nfit_test emulated driver provides 2 buses, that is why
some of the range indices are duplicated. Notice that each range
now successfully completes a short and long scrub.
