iio: adc: ti-ads7950: Add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
SPI device registered via OF will always match a legacy SPI device ID and
that the MODALIAS reported will always be of the form spi:<device>.
There is an ACPI method to enumerate such devices via specific ACPI ID
and use of compatible strings. It will not work for the drivers which
have no OF match ID table present.
Besides this could change in the future so the correct approach is to
have an OF device ID table if the devices are registered via OF.

iio: adc: stm32: add optional st,min-sample-time-nsecs
STM32 ADC allows each channel to be sampled with a different sampling time,
by setting SMPR registers. Basically, value depends on local electrical
properties. Selecting correct value for sampling time highly depends on
analog source impedance. There is a manual that may help in this process:
'How to get the best ADC accuracy in STM32...'
This patch allows to configure minimum sampling time via device tree,
either for:
- all channels at once:
st,min-sample-time-nsecs = <10000>;
- independently for each channel (must match "st,adc-channels" list):
st,adc-channels = <0 1>;

First round of IIO new device support, features and cleanups for the 4.14 cycle.
4 completely new drivers in this set and plenty of other stuff.
One ABI change due to a silly mistake a long time back. Hopefully no
one will notice. It effects the numerical order of consumer device
channels which was the reverse of the obvious. It's going the slow
way to allow us some margin to spot if we have broken userspace or
not (seems unlikely)
New Device Support
* ccs811
- new driver for the Volatile Organic Compounds (VOC) sensor.
* dln2 adc
- new driver for the ADC on this flexible usb board.
* EP93xx
- new driver for this Cirrus logic SoC ADC.
* ltc2471
- new ADC driver support the ltc2471 and ltc2473
* st_accel
- add trivial table entries to support H3LIS331DL, LIS331DL, LIS3LV02DL.
* st_gyro
- add L3GD20H support (again) having fixed the various things that were
broken in the first try. Includes devicetree binding.
* stm32 dac
- add support for the DACs in the STM32F4 series
Features
* Documentation
- add missing power attribute documentation to the ABI docs.
* at91-sama5d2
- add hardware trigger and buffered capture support with bindings.
- suspend and resume functionality.
* bmc150
- support for the BOSC0200 ACPI device id seen on some tablets.
* hdc100x
- devicetree bindings
- document supported devices
- match table and device ids.
* hts221
- support active low interrupts (with bindings)
- open drain mode with bindings.
* htu21
- OF match table and bindings.
* lsm6dsx
- open drain mode with bindings
* ltc2497
- add support for board file based consumer mapping.
* ms5367
- OF match table and bindings.
* mt7622
- binding document and OF match table.
- suspend and resume support.
* rpr0521
- triggered buffer support.
* tsys01
- OF match table and bindings.
Cleanups and minor fixes
* core
- fix ordering of IIO channels to entry numbers when using
iio_map_array_register rather than reversing them.
- use the new %pOF format specifier rather than full name for the
device tree nodes.
*
ad7280a
- fix potential issue with macro argument reuse.
* ad7766
- drop a pointless NULL value check as it's done in the gpiod code.
* adis16400
- unsigned -> unsigned int.
* at91 adc
- make some init data static to reduce code size.
* at91-sama5d2 ADC
- make some init data static to reduce code size.
* da311
- make some init data static to reduce code size.
* hid-sensor-rotation
- drop an unnecessary static.
* hts221
- refactor the write_with_mask code.
- move the BDU configuration to probe time as there is no reason for it
to change.
- avoid overwriting reserved data during power-down. This is a fix, but
the infrastructure need was too invasive to send it to mainline except
in a merge window. It's not a regression as it was always wrong.
- avoid reconfigure the sampling frequency multiple times by just
doing it in the write_raw function directly.
- refactor the power_on/off calls into a set_enable.
- move the dry-enable logic into trig_set_state as that is the only
place it was used.
* ina219
- fix polling of ina226 conversion ready flag.
* imx7d
- add vendor name in kconfig for consistency with similar parts.
* mcp3422
- Change initial channel to 0 as it feels more logical.
- Check for some errors in probe.
* meson-saradc
- add a check of of_match_device return value.
* mpu3050
- allow open drain for any interrupt type.
* rockchip adc
- add check on of_match_device return value.
* sca3000
- drop a trailing whitespace.
* stm32 adc
- make array stm32h7_adc_ckmodes_spec static.
* stm32 dac
- fix an error message.
* stm32 timers
- fix clock name in docs to match reality after changes.
* st_accel
- explicit OF table (spi).
- add missing entries to OF table (i2c).
- rename of_device_id table to drop the part name.
- adding missing lis3l02dq entry to bindings.
- rename H3LIS331DL_DRIVER_NAME to line up with similar entries in driver.

- there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all

xen/balloon: don't online new memory initially
When setting up the Xenstore watch for the memory target size the new
watch will fire at once. Don't try to reach the configured target size
by onlining new memory in this case, as the current memory size will
be smaller in almost all cases due to e.g. BIOS reserved pages.
Onlining new memory will lead to more problems e.g. undesired conflicts
with NVMe devices meant to be operated as block devices.
Instead remember the difference between target size and current size
when the watch fires for the first time and apply it to any further
size changes, too.
In order to avoid races between balloon.c and xen-balloon.c init calls
do the xen-balloon.c initialization from balloon.c.

- For current: raw value is in microamps

net/sunrpc/xprt_sock: fix regression in connection error reporting.
Commit
3d4762639dd3 ("tcp: remove poll() flakes when receiving
RST") in v4.12 changed the order in which ->sk_state_change()
and ->sk_error_report() are called when a socket is shut
down - sk_state_change() is now called first.
This causes xs_tcp_state_change() -> xs_sock_mark_closed() ->
xprt_disconnect_done() to wake all pending tasked with -EAGAIN.
When the ->sk_error_report() callback arrives, it is too late to
pass the error on, and it is lost.
As easy way to demonstrate the problem caused is to try to start
rpc.nfsd while rcpbind isn't running.
nfsd will attempt a tcp connection to rpcbind. A ECONNREFUSED
error is returned, but sunrpc code loses the error and keeps
retrying. If it saw the ECONNREFUSED, it would abort.
To fix this, handle the sk->sk_err in the TCP_CLOSE branch of
xs_tcp_state_change().

perf/x86/intel: Add proper condition to run sched_task callbacks
We have 2 functions using the same sched_task callback:
- PEBS drain for free running counters
- LBR save/store
Both of them are called from intel_pmu_sched_task() and
either of them can be unwillingly triggered when the
other one is configured to run.
Let's say there's PEBS drain configured in sched_task
callback for the event, but in the callback itself
(intel_pmu_sched_task()) we will also run the code for
LBR save/restore, which we did not ask for, but the
code in intel_pmu_sched_task() does not check for that.
This can lead to extra cycles in some perf monitoring,
like when we monitor PEBS event without LBR data.
# perf record --no-timestamp -c 10000 -e cycles:p ./perf bench sched pipe -l
1000000
(We need PEBS, non freq/non timestamp event to enable
the sched_task callback)
The perf stat of cycles and msr:write_msr for above
command before the change:
...
Performance counter stats for './perf record --no-timestamp -c 10000 -e cycles:p \
./perf bench sched pipe -l
1000000' (5 runs):
18,519,557,441 cycles:k
91,195,527 msr:write_msr
29.
334476406 seconds time elapsed
And after the change:
...
Performance counter stats for './perf record --no-timestamp -c 10000 -e cycles:p \
./perf bench sched pipe -l
1000000' (5 runs):
18,704,973,540 cycles:k
27,184,720 msr:write_msr
16.
977875900 seconds time elapsed
There's no affect on cycles:k because the sched_task happens
with events switched off, however the msr:write_msr tracepoint
counter together with almost 50% of time speedup show the
improvement.
Monitoring LBR event and having extra PEBS drain processing
in sched_task callback showed just a little speedup, because
the drain function does not do much extra work in case there
is no PEBS data.
Adding conditions to recognize the configured work that needs
to be done in the x86_pmu's sched_task callback.

perf/core: Fix locking for children siblings group read
We're missing ctx lock when iterating children siblings
within the perf_read path for group reading. Following
race and crash can happen:
User space doing read syscall on event group leader:
T1:
perf_read
lock event->ctx->mutex
perf_read_group
lock leader->child_mutex
__perf_read_group_add(child)
list_for_each_entry(sub, &leader->sibling_list, group_entry)
----> sub might be invalid at this point, because it could
get removed via perf_event_exit_task_context in T2
Child exiting and cleaning up its events:
T2:
perf_event_exit_task_context
lock ctx->mutex
list_for_each_entry_safe(child_event, next, &child_ctx->event_list,...
perf_event_exit_event(child)
lock ctx->lock
perf_group_detach(child)
unlock ctx->lock
----> child is removed from sibling_list without any sync
with T1 path above
...
free_event(child)
Before the child is removed from the leader's child_list,
(and thus is omitted from perf_read_group processing), we
need to ensure that perf_read_group touches child's
siblings under its ctx->lock.

| One additional note; this bug got exposed by commit:
