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.
* st_gyro
- explicit OF table (spi).
* st_magn
- explicit OF table (spi).
- enable multiread for lis3mdl.
* st_pressure
- explicit OF table (spi).
* st_sensors common.
- move st_sensors_of_i2c_probe and rename to make it available for spi
drivers.
* tsc3472
- don't write an extra byte when writing the ATIME register.
- add a link to the datasheet.
* tsl2x7x - continued staging cleanups
- add of_match_table.
- drop redundant power_state sysfs attribute.
- drop wrapper tsl2x7x_i2c_read.
- clean up i2c calls made in tsl2x7x_als_calibrate.
- refactor the read and write _event_value callbacks to handle additional
elements.
- use usleep_range instead of mdelay.
- check return value from tsl2x7x_invoke_change.
* zpa2326
- add some newline to the end of logging macros.

Fix up MAINTAINERS file problems
Prepping for scripting the MAINTAINERS file cleanup (and possible split)
showed a couple of cases where the headers for a couple of entries were
bogus.
There's a few different kinds of bogosities:
- the X-GENE SOC EDAC case was confused and split over two lines
- there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all
different things.
- the NOKIA N900 CAMERA SUPPORT" was duplicated
all of which were more obvious when you started doing associative arrays
in perl to track these things by the header (so that we can alphabetize
this thing properly, and so that we might split it up by the data too).

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.

cpu_startup_entry(CPUHP_AP_ONLINE_IDLE) from xen_play_dead()")
introduced an error leading to a stack overflow of the idle task when
a cpu was brought offline/online many times: by calling
cpu_startup_entry() instead of returning at the end of xen_play_dead()
do_idle() would be entered again and again.
Don't use cpu_startup_entry(), but cpuhp_online_idle() instead allowing
to return from xen_play_dead().

- For current: raw value is in microamps

- For eCO2: raw value range is from 400ppm to 8192ppm.

(val - 400) * 0.

-For TVOC: raw value range is from 0ppb to 1187ppb.

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.
Peter further notes:
| One additional note; this bug got exposed by commit:

ba5213ae6b88 ("perf/core: Correct event creation with PERF_FORMAT_GROUP")

cp->cp_send_gen is treated as a normal variable, although it may be
used by different threads.
This is fixed by using {READ,WRITE}_ONCE when it is incremented and
READ_ONCE when it is read outside the {acquire,release}_in_xmit
protection.
Normative reference from the Linux-Kernel Memory Model:
Loads from and stores to shared (but non-atomic) variables should
be protected with the READ_ONCE(), WRITE_ONCE(), and
ACCESS_ONCE().
Clause 5.1.2.4/25 in the C standard is also relevant.

net: ethernet: ti: cpsw: Push the request_irq function to the end of probe
Push the request_irq function to the end of probe so as
to ensure all the required fields are populated in the event
of an ISR getting executed right after requesting the irq.
Currently while loading the crash kernel a crash was seen as
soon as devm_request_threaded_irq was called. This was due to
n->poll being NULL which is called as part of net_rx_action
function.

ipv4: initialize fib_trie prior to register_netdev_notifier call.
Net stack initialization currently initializes fib-trie after the
first call to netdevice_notifier() call. In fact fib_trie initialization
needs to happen before first rtnl_register(). It does not cause any problem
since there are no devices UP at this moment, but trying to bring 'lo'
UP at initialization would make this assumption wrong and exposes the issue.

rtnetlink: allocate more memory for dev_set_mac_address()
virtnet_set_mac_address() interprets mac address as struct
sockaddr, but upper layer only allocates dev->addr_len
which is ETH_ALEN + sizeof(sa_family_t) in this case.
We lack a unified definition for mac address, so just fix
the upper layer, this also allows drivers to interpret it
to struct sockaddr freely.
