option):
$ perf test -Fv
...
34: Test thread map :

The reason was the process name wasn't 'perf' as expected by the test,
because other tests set the name as well.

This adds runtime PM support to the AK8975 driver. It solves two
problems:
- After reading the first value the chip was left in MODE_ONCE,
meaning (presumably) it may be consuming more power. Now the
runtime PM hooks kick in and set it to POWER_DOWN.
- Regulators were simply enabled and left on, making it
impossible to turn the power consuming regulators off because
of the increased refcount. We now disable the regulators at
autosuspend.
- We also handle system suspend: by using pm_runtime_force_suspend()
and pm_runtime_force_resume() from the system PM sleep hooks,
the runtime PM code is managing the power also for this case.
It is currently not completely optimal: when the system resumes
the AK8975 goes into active mode even if noone is going to use
it: currently the force calls need to be paired, but the runtime
PM people are working on making it possible to leave devices
runtime suspended when coming back from sleep.
Inspired by my work on the BH1780 light sensor driver.

IS_ERR_OR_NULL() should never be used with regulators because
a NULL pointer may be a perfectly valid dummy regulator
We should always succeed to fetch and enable a regulator, but
it may be a dummy. That is fine, so bail out for any real
errors or probe deferrals
Include the error code in the warning print so we know what
kind of problem we're dealing with (for example it is nice to
see if it is a probe deferral).
As we will bail out of probe if the regulator is erroneous,
just issue regulator_disable() on the poweroff path: it will
succeed.

means that the extcon core now fails to build because the internal

ERROR: extcon_dev_allocate [drivers/extcon/devres.ko] undefined!
My guess is that the intention was not to have two separate
modules (which could be fixed by adding an export, plus the
normal MODULE_AUTHOR/MODULE_LICENSE/... fields), but have two
source files in the same module.
This fixes the Makefile accordingly, making the name of the

ip_skb_dst_mtu uses skb->sk, assuming it is an AF_INET socket (e.g. it
calls ip_sk_use_pmtu which casts sk as an inet_sk).
However, in the case of UDP tunneling, the skb->sk is not necessarily an
inet socket (could be AF_PACKET socket, or AF_UNSPEC if arriving from
tun/tap).
OTOH, the sk passed as an argument throughout IP stack's output path is
the one which is of PMTU interest:
- In case of local sockets, sk is same as skb->sk;
- In case of a udp tunnel, sk is the tunneling socket.
Fix, by passing ip_finish_output's sk to ip_skb_dst_mtu.

The simple_write_to_buffer() already increments the @ppos on success,
see fs/libfs.c simple_write_to_buffer() comment:
"
On success, the number of bytes written is returned and the offset @ppos
advanced by this number, or negative value is returned on error.
"
If the configfs_write_bin_file() is invoked with @count smaller than the
total length of the written binary file, it will be invoked multiple times.
Since configfs_write_bin_file() increments @ppos on success, after calling
simple_write_to_buffer(), the @ppos is incremented twice.
Subsequent invocation of configfs_write_bin_file() will result in the next
piece of data being written to the offset twice as long as the length of
the previous write, thus creating buffer with "holes" in it.
The simple testcase using DTO follows:
$ mkdir /sys/kernel/config/device-tree/overlays/1
$ dd bs=1 if=foo.dtbo of=/sys/kernel/config/device-tree/overlays/1/dtbo
Without this patch, the testcase will result in twice as big buffer in the
kernel, which is then passed to the cfs_overlay_item_dtbo_write() .

Commit d6a9996e84 ("powerpc/mm: vmalloc abstraction in preparation for
radix") turned kernel memory and IO addresses from #defined constants to
variables initialised at runtime.
On PA6T (pasemi) systems the setup_arch() machine call initialises the
onboard PCI-e root-ports, and uses pci_io_base to do this, which is now
before its value has been set, resulting in a panic early in boot before
console IO is initialised.
Move the pci_io_base initialisation to the same place as vmalloc ranges
are set (hash__early_init_mmu()/radix__early_init_mmu()) - this is the
earliest possible place we can initialise it.

When configuring FPS during probe, assuming a DT node is present for
FPS, the code can run into a problem with the switch statements in
max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely,
in the case of chip->chip_id == MAX77620, it will set
fps_[mix|max]_period but then fall through to the default switch case
and return -EINVAL. Returning this from max77620_config_fps() will
cause probe to fail.

Pull RCU changes from Paul E. McKenney:
- Documentation updates. Just some simple changes, no design-level
additions.
- Miscellaneous fixes.
- Torture-test updates.
Signed-off-by: Ingo Molnar <mingo@kernel.org>
Firstly some contact detail updates:
* NXP took over freescale. Update the mma8452 header to reflect this.
* Martin Kepplinger email address change in mma8452 header.
* Adriana Reus has changed email address. Update .mailmap.
* Matt Ranostay has changed email address. Update .mailmap.
New Device Support
* max1363
- add the missing i2c_device_ids for a couple of parts so they can actually
be used.
* ms5867
- add device ids for ms5805 and ms5837 parts.
New Features
* ad5755
- DT support. This one was a bit controversial and under review for a long
time. Still no one could come up with a better solution.
* stx104
- add gpio support
* ti-adc081c
- Add ACPI device ID matching.
Core changes
* Refuse to register triggers with duplicate names. There is no way to
distinguish between them so this makes no sense. A few drivers do not
generate unique names for each instance of the device present. We can't
fix this without changing ABI so leave them and wait for someone to
actually take the rare step of two identical accelerometers on the same
board.
* buffer-dma
- use ARRAY_SIZE in a few appropriate locations.
Tools
* Fix the fact that the --trigger-num option in generic_buffer didn't allow
0 which is perfectly valid in the ABI.
Cleanups
* as3935
- improve error reporting.
- remove redundant zeroing of a field in iio_priv.
* gp2ap020a00f
- use the iio_device_claim_*_mode helpers rather than open coding locking
around mode changes.
