Power management updates for v4.16-rc1
- Define a PM driver flag allowing drivers to request that their
devices be left in suspend after system-wide transitions to the
working state if possible and add support for it to the PCI bus
type and the ACPI PM domain (Rafael Wysocki).
- Make the PM core carry out optimizations for devices with driver
PM flags set in some cases and make a few drivers set those flags
(Rafael Wysocki).
- Fix and clean up wrapper routines allowing runtime PM device
callbacks to be re-used for system-wide PM, change the generic
power domains (genpd) framework to stop using those routines
incorrectly and fix up a driver depending on that behavior of
genpd (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).
- Fix and clean up the PM core's device wakeup framework and
re-factor system-wide PM core code related to device wakeup
(Rafael Wysocki, Ulf Hansson, Brian Norris).
- Make more x86-based systems use the Low Power Sleep S0 _DSM
interface by default (to fix power button wakeup from
suspend-to-idle on Surface Pro3) and add a kernel command line
switch to tell it to ignore the system sleep blacklist in the
ACPI core (Rafael Wysocki).
- Fix a race condition related to cpufreq governor module removal
and clean up the governor management code in the cpufreq core
(Rafael Wysocki).
- Drop the unused generic code related to the handling of the static
power energy usage model in the CPU cooling thermal driver along
with the corresponding documentation (Viresh Kumar).
- Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh Cheng).
- Add a new operating point to the imx6ul and imx6q cpufreq drivers
and switch the latter to using clk_bulk_get() (Anson Huang, Dong
Aisheng).
- Add support for multiple regulators to the TI cpufreq driver along
with a new DT binding related to that and clean up that driver
somewhat (Dave Gerlach).
- Fix a powernv cpufreq driver regression leading to incorrect CPU
frequency reporting, fix that driver to deal with non-continguous
P-states correctly and clean it up (Gautham Shenoy, Shilpasri Bhat).
- Add support for frequency scaling on Armada 37xx SoCs through the
generic DT cpufreq driver (Gregory CLEMENT).
- Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).
- Fix a transition delay setting regression in the longhaul cpufreq
driver (Viresh Kumar).
- Add Skylake X (server) support to the intel_pstate cpufreq driver
and clean up that driver somewhat (Srinivas Pandruvada).
- Clean up the cpufreq statistics collection code (Viresh Kumar).
- Drop cluster terminology and dependency on physical_package_id
from the PSCI driver and drop dependency on arm_big_little from
the SCPI cpufreq driver (Sudeep Holla).
- Add support for system-wide suspend and resume to the RAPL power
capping driver and drop a redundant semicolon from it (Zhen Han,
Luis de Bethencourt).
- Make SPI domain validation (in the SCSI SPI transport driver) and
system-wide suspend mutually exclusive as they rely on the same
underlying mechanism and cannot be carried out at the same time
(Bart Van Assche).
- Fix the computation of the amount of memory to preallocate in the
hibernation core and clean up one function in there (Rainer Fiebig,
Kyungsik Lee).
- Prepare the Operating Performance Points (OPP) framework for being
used with power domains and clean up one function in it (Viresh
Kumar, Wei Yongjun).
- Clean up the generic sysfs interface for device PM (Andy Shevchenko).
- Fix several minor issues in power management frameworks and clean
them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,
Sergey Senozhatsky, gaurav jindal).
- Make it easier to disable PM via Kconfig (Mark Brown).
- Clean up the cpupower and intel_pstate_tracer utilities (Doug
Smythies, Laura Abbott).

Pull power management updates from Rafael Wysocki:
"This includes some infrastructure changes in the PM core, mostly
related to integration between runtime PM and system-wide suspend and
hibernation, plus some driver changes depending on them and fixes for
issues in that area which have become quite apparent recently.
Also included are changes making more x86-based systems use the Low
Power Sleep S0 _DSM interface by default, which turned out to be
necessary to handle power button wakeups from suspend-to-idle on
Surface Pro3.
On the cpufreq front we have fixes and cleanups in the core, some new
hardware support, driver updates and the removal of some unused code
from the CPU cooling thermal driver.
Apart from this, the Operating Performance Points (OPP) framework is
prepared to be used with power domains in the future and there is a
usual bunch of assorted fixes and cleanups.

devices be left in suspend after system-wide transitions to the

sound updates for 4.16-rc1
The major changes in the core API side in this cycle are the still
on-going ASoC componentization works. Other than that, only few small
changes such as 20bit PCM format support are found.
Meanwhile the rest majority of changes are for ASoC drivers:
- Large cleanups of some of the TI CODEC drivers
- Continued work on Intel ASoC stuff for new quirks, ACPI GPIO
handling, Kconfigs and lots of cleanups
- Refactoring of the Freescale SSI driver, as preliminary work for the
upcoming changes
- Work on ST DFSDM driver, including the required IIO patches
- New drivers for Allwinner A83T, Maxim MAX89373, SocioNext UiniPhier
EVEA Tempo Semiconductor TSCS42xx and TI PCM816x, TAS5722 and TAS6424
devices
- Removal of dead codes for SN95031 and board drivers
Last but not least, a few HD-audio and USB-audio quirks are included
as usual, too.

Pull init_task initializer cleanups from David Howells:
"It doesn't seem useful to have the init_task in a header file rather
than in a normal source file. We could consolidate init_task handling
instead and expand out various macros.
Here's a series of patches that consolidate init_task handling:
(1) Make THREAD_SIZE available to vmlinux.lds for cris, hexagon and
openrisc.
(2) Alter the INIT_TASK_DATA linker script macro to set
init_thread_union and init_stack rather than defining these in C.
Insert init_task and init_thread_into into the init_stack area in
the linker script as appropriate to the configuration, with
different section markers so that they end up correctly ordered.
We can then get merge ia64's init_task.c into the main one.
We then have a bunch of single-use INIT_*() macros that seem only
to be macros because they used to be used per-arch. We can then
expand these in place of the user and get rid of a few lines and
a lot of backslashes.
(3) Expand INIT_TASK() in place.
(4) Expand in place various small INIT_*() macros that are defined
conditionally. Expand them and surround them by #if[n]def/#endif
in the .c file as it takes fewer lines.
(5) Expand INIT_SIGNALS() and INIT_SIGHAND() in place.
(6) Expand INIT_STRUCT_PID in place.
These macros can then be discarded"

Calling fan related SMM functions implemented by Dell BIOS firmware on Dell Vostro 3360 freeze kernel for about 500ms.

hrtimer: Reset hrtimer cpu base proper on CPU hotplug
The hrtimer interrupt code contains a hang detection and mitigation
mechanism, which prevents that a long delayed hrtimer interrupt causes a
continous retriggering of interrupts which prevent the system from making
progress. If a hang is detected then the timer hardware is programmed with
a certain delay into the future and a flag is set in the hrtimer cpu base
which prevents newly enqueued timers from reprogramming the timer hardware
prior to the chosen delay. The subsequent hrtimer interrupt after the delay
clears the flag and resumes normal operation.
If such a hang happens in the last hrtimer interrupt before a CPU is
unplugged then the hang_detected flag is set and stays that way when the
CPU is plugged in again. At that point the timer hardware is not armed and
it cannot be armed because the hang_detected flag is still active, so
nothing clears that flag. As a consequence the CPU does not receive hrtimer
interrupts and no timers expire on that CPU which results in RCU stalls and
other malfunctions.
Clear the flag along with some other less critical members of the hrtimer
cpu base to ensure starting from a clean state when a CPU is plugged in.
Thanks to Paul, Sebastian and Anna-Maria for their help to get down to the
root cause of that hard to reproduce heisenbug. Once understood it's
trivial and certainly justifies a brown paperbag.

x86: Mark hpa as a "Designated Reviewer" for the time being
Due to some unfortunate events, I have not been directly involved in the x86 kernel patch flow for a while now. I have also not been able to ramp back up by now like I had hoped to, and after reviewing what I will need to work on both internally at Intel and elsewhere in the near term, it is clear that I am not going to be able to ramp back up until late 2018 at the very earliest. It is not acceptable to not recognize that this load is currently taken by Ingo and Thomas without my direct participation, so I mark myself as R: (designated reviewer) rather than M: (maintainer) until further notice. This is in fact recognizing the de facto situation for the past few years. I have obviously no intention of going away, and I will do everything within my power to improve Linux on x86 and x86 for Linux. This, however, puts credit where it is due and reflects a change of focus. This patch also removes stale entries for portions of the x86 architecture which have not been maintained separately from arch/x86 for a long time. If there is a reason to re-introduce them then that can happen later. Signed-off-by: H.

RISC-V: We have a new mailing list and git repo!
Sorry to send something essentially as late as possible (Friday after an rc9), but we managed to get a mailing list for the RISC-V Linux port. We've been using patches@groups.riscv.org for a while, but that list has some problems (it's Google Groups and it's shared over all RISC-V software projects). The new infaread.org list is much better. We just got it on Wednesday but I used it a bit on Thursday to shake out all the configuration problems and it appears to be in working order. When I updated the mailing list I noticed that the MAINTAINERS file was pointing to our github repo, but now that we have a kernel.org repo I'd like to point to that instead so I changed that as well. We'll be centralizing all RISC-V Linux related development here as that seems to be the saner way to go about it. I can understand if it's too late to get this into 4.15, but given that it's not a code change I was hoping it'd still be OK.

Currently select(2) does not return for virtio-vsock when a SEND+RCV shutdown packet is received.

x86/mm/64: Tighten up vmalloc_fault() sanity checks on 5-level kernels
On a 5-level kernel, if a non-init mm has a top-level entry, it needs to
match init_mm's, but the vmalloc_fault() code skipped over the BUG_ON()
that would have checked it.
While we're at it, get rid of the rather confusing 4-level folded "pgd"
logic.

x86/mm/64: Fix vmapped stack syncing on very-large-memory 4-level systems
Neil Berrington reported a double-fault on a VM with 768GB of RAM that uses
large amounts of vmalloc space with PTI enabled.
The cause is that load_new_mm_cr3() was never fixed to take the 5-level pgd
folding code into account, so, on a 4-level kernel, the pgd synchronization
logic compiles away to exactly nothing.
Interestingly, the problem doesn't trigger with nopti. I assume this is
because the kernel is mapped with global pages if we boot with nopti. The
sequence of operations when we create a new task is that we first load its
mm while still running on the old stack (which crashes if the old stack is
unmapped in the new mm unless the TLB saves us), then we call
prepare_switch_to(), and then we switch to the new stack.
prepare_switch_to() pokes the new stack directly, which will populate the
mapping through vmalloc_fault(). I assume that we're getting lucky on
non-PTI systems -- the old stack's TLB entry stays alive long enough to
make it all the way through prepare_switch_to() and switch_to() so that we
make it to a valid stack.

net: tcp: close sock if net namespace is exiting
When a tcp socket is closed, if it detects that its net namespace is exiting, close immediately and do not wait for FIN sequence. For normal sockets, a reference is taken to their net namespace, so it will never exit while the socket is open. However, kernel sockets do not take a reference to their net namespace, so it may begin exiting while the kernel socket is still open. In this case if the kernel socket is a tcp socket, it will stay open trying to complete its close sequence. The sock's dst(s) hold a reference to their interface, which are all transferred to the namespace's loopback interface when the real interfaces are taken down. When the namespace tries to take down its loopback interface, it hangs waiting for all references to the loopback interface to release, which results in messages like: unregister_netdevice: waiting for lo to become free. Usage count = 1 These messages continue until the socket finally times out and closes. Since the net namespace cleanup holds the net_mutex while calling its registered pernet callbacks, any new net namespace initialization is blocked until the current net namespace finishes exiting. After this change, the tcp socket notices the exiting net namespace, and closes immediately, releasing its dst(s) and their reference to the loopback interface, which lets the net namespace continue exiting.

perf/core: Fix ctx::mutex deadlock
Lockdep noticed the following 3-way lockup scenario: sys_perf_event_open() perf_event_alloc() perf_try_init_event() #0 ctx = perf_event_ctx_lock_nested(1) perf_swevent_init() swevent_hlist_get() #1 mutex_lock(&pmus_lock) perf_event_init_cpu() #1 mutex_lock(&pmus_lock) #2 mutex_lock(&ctx->mutex) sys_perf_event_open() mutex_lock_double() #2 mutex_lock() #0 mutex_lock_nested() And while we need that perf_event_ctx_lock_nested() for HW PMUs such that they can iterate the sibling list, trying to match it to the available counters, the software PMUs need do no such thing. Exclude them. In particular the swevent triggers the above invertion, while the tpevent PMU triggers a more elaborate one through their event_mutex.

perf/core: Fix another perf,trace,cpuhp lock inversion
Lockdep noticed the following 3-way lockup race:
perf_trace_init()
#0 mutex_lock(&event_mutex)
perf_trace_event_init()
perf_trace_event_reg()
tp_event->class->reg() := tracepoint_probe_register
#1 mutex_lock(&tracepoints_mutex)
trace_point_add_func()
#2 static_key_enable()
#2 do_cpu_up()
perf_event_init_cpu()
#3 mutex_lock(&pmus_lock)
#4 mutex_lock(&ctx->mutex)
perf_ioctl()
#4 ctx = perf_event_ctx_lock()
_perf_iotcl()
ftrace_profile_set_filter()
#0 mutex_lock(&event_mutex)
Fudge it for now by noting that the tracepoint state does not depend
on the event <-> context relation. Ugly though :/

perf/core: Fix lock inversion between perf,trace,cpuhp
Lockdep gifted us with noticing the following 4-way lockup scenario:
perf_trace_init()
#0 mutex_lock(&event_mutex)
perf_trace_event_init()
perf_trace_event_reg()
tp_event->class->reg() := tracepoint_probe_register

#4 mutex_lock(&ctx->mutex)
#5 mutex_lock(&event->child_mutex)
free_event()
_free_event()
event->destroy() := perf_trace_destroy
#0 mutex_lock(&event_mutex);
Fix that by moving the free_event() out from under the locks.

mtd: nand: sunxi: Fix ECC strength choice
When the requested ECC strength does not exactly match the strengths
supported by the ECC engine, the driver is selecting the closest
strength meeting the 'selected_strength > requested_strength'
constraint. Fix the fact that, in this particular case, ecc->strength
value was not updated to match the 'selected_strength'.
For instance, one can encounter this issue when no ECC requirement is
filled in the device tree while the NAND chip minimum requirement is not
a strength/step_size combo natively supported by the ECC engine.
