b1c04e80c6 libata: return boolean values from ata_is_*
This way we don't have to worry about the exact bit postition of the
test to leak out and any crazy propagation effects in the callers.

55d38d060e i2c: core: Add function for finding the bus speed from ACPI
ACPI 5 specification doesn't have property for the I2C bus speed but
I2cSerialBus resource descriptors which define each controller-slave
connection define the maximum speed supported by that connection.

Thus finding the maximum safe speed for the bus is to walk all
I2cSerialBus resources that are associated to I2C controller and use
the speed of slowest connection.

Add function i2c_acpi_find_bus_speed() to the i2c-core that adapter
drivers can call prior registering itself to core.

This implies two-step walk through the I2cSerialBus resources: call to
i2c_acpi_find_bus_speed() does the first scan and finds the safe bus
speed that adapter drivers can set up. Adapter driver registration does
the second scan when i2c-core creates the I2C slaves by calling the
i2c_acpi_register_devices(). In that way the bus speed is set in case
slave device probe gets called during registration and does
communication.

Implement this by reusing the existing ACPI I2C walk routines in the
i2c-core. Extend them so that slowest connection speed is saved during
the walk and I2C slaves are registered only when calling through the
i2c_acpi_register_devices() with the i2c_adapter pointer.

8612f17ab9 sched/cputime: Reorganize vtime native irqtime accounting headers
The vtime irqtime accounting headers are very scattered and convoluted
right now. Reorganize them such that it is obvious that only
CONFIG_VIRT_CPU_ACCOUNTING_NATIVE does use it.

0cfdf9a198 sched/cputime: Clean up the old vtime gen irqtime accounting completely
Vtime generic irqtime accounting has been removed but there are a few
remnants to clean up:

* The vtime_accounting_cpu_enabled() check in irq entry was only used
  by CONFIG_VIRT_CPU_ACCOUNTING_GEN. We can safely remove it.

* Without the vtime_accounting_cpu_enabled(), we no longer need to
  have a vtime_common_account_irq_enter() indirect function.

* Move vtime_account_irq_enter() implementation under
  CONFIG_VIRT_CPU_ACCOUNTING_NATIVE which is the last user.

* The vtime_account_user() call was only used on irq entry for
  CONFIG_VIRT_CPU_ACCOUNTING_GEN. We can remove that too.

b58c358405 sched/cputime: Replace VTIME_GEN irq time code with IRQ_TIME_ACCOUNTING code
The CONFIG_VIRT_CPU_ACCOUNTING_GEN irq time tracking code does not
appear to currently work right.

On CPUs without nohz_full=, only tick based irq time sampling is
done, which breaks down when dealing with a nohz_idle CPU.

On firewalls and similar systems, no ticks may happen on a CPU for a
while, and the irq time spent may never get accounted properly. This
can cause issues with capacity planning and power saving, which use
the CPU statistics as inputs in decision making.

Remove the VTIME_GEN vtime irq time code, and replace it with the
IRQ_TIME_ACCOUNTING code, when selected as a config option by the user.

Convert the notifiers to state machine states and let the core code do the
setup for the already online CPUs. This notifier has a completely undocumented
ordering requirement versus perf hardcoded in the notifier priority. This
odering is only required for CPU down, so that hardware migration happens
before the core is notified about the outgoing CPU.

00e16c3d68 perf/core: Convert to hotplug state machine
Actually a nice symmetric startup/teardown pair which fits properly into
the state machine concept. In the long run we should be able to invoke
the startup callback for the boot CPU via the state machine and get
rid of the init function which invokes it on the boot CPU.

Note: This comes actually before the perf hardware callbacks. In the notifier
model the hardware callbacks have a higher priority than the core
callback. But that's solely for CPU offline so that hardware migration of
events happens before the core is notified about the outgoing CPU.

With the symetric state array model we have the following ordering:

 UP:     core -> hardware
 DOWN:   hardware -> core

More or less straightforward, although this driver sports some very

deleted comment is interesting:

   ... the GIC needs to be up before the ARM generic timers.

That comment is half baken as the same requirement is true for perf.

   as it makes little sense to have events in one timebase and data timestamped
   on another.  Biggest reason for this is that we currently use a clock
   source which is non monotonic which can result in 'interesting' data sets.
   (Includes export for get_monotonic_corse64 which Thomas Gleixner didn't mind
    in an earlier version.)
 - MAINTAINERS add the git tree to the list for IIO.

 * Broadcom iproc-static-adc
   - new driver
 * mcp4531
   - support for MCP454x, MCP456x, MCP464x and MCP466x potentiometers
 * mpu6050
   - support the IC20608 6 axis motion tracking device
 * st-sensors
   - support the lis3l02dq + drop the lis3l02dq driver from staging.
   The general purpose driver is missing event support, but good to get
   rid of this driver which was rather long in the tooth.
 
 New driver features
 * ak8975
   - Add vid regulator support and refactor handling in general.
   - Allow a delay after enabling regulators.
   - Runtime and system PM.
 * bmg160

   - drop an unecessary bit of return value handling.
 * potentiometer kconfig
   - typo fix.
 * st-pressure
   - drop some uninformative default assignments of elements of the channel
   array structure (aids readability).
 * st-sensors
   - Harden interrupt handling considerably.  These are actually all using
   level interrupts, but at least two known boards have them wired to
   edge only interrupt chips.  Hence a slightly interesting bit of handling
   is needed in which we first allow for the easy option (level triggered) and
   secondly check the status registers before reenabling edge interrupts and
   fall back to a tight loop in the thread until we successfully clear the
   interrupt.  No harm is done if we never succeed in doing so.  It's an odd
   patch that has been through a lot of revisions to reach a consensus on how
   to handle what is basically broken hardware (which the previous defaults
   allowed to kind of work).
   - Fix alignment to defined storagebytes boundaries.
   - Ensure alignment of power of 2 byte boundaries.  This has always in theory
   been part of the ABI of IIO, but we missed a few that snuck in that need

7f96a82fde Update extcon for 4.8
Detailed description for patchset:
 1. Update the extcon-gpio.c driver
 - Use PM wakeirq APIs and support to check the state of external connector
   when wake-up from suspend state if the interrupt of external connector is
   not used as wakeup source.
 - Support for ACPI gpio interface
 
 2. Remove deprecated extcon APIs using the legacy cable name
 - The extcon framework handle the external connector only by unique id
   instead of legacy cable name to prevent the problem.
 - Removed functions
   : extcon_get_cable_state()
   : extcon_set_cable_state()
   : extcon_register_interest()
   : extcon_unregister_interest()
 - It has the dependency on the axp288_charger.c driver.
   So, this pull request includes the 'ib-extcon-powersupply-4.8'
   immutable branch to protect the merge conflict.
 
 3. Support the resource-managed function for extcon_register_notifier
 - Add the devm_extcon_register/unregister_notifier() funticon to handle
   the resource automatically by resource managed functions and split out
   the resource-managed function from extcon core to seprate file(devres.c).
 
 4. Supprot the suspend/resume for extcon-adc-jack.c driver
 - Add the support the suspend/resume function to use extcon-adc-jack.c
   as wakeup source.
 
 5. Fix the minor issue
 - Check the return value of find_cable_index_by_id()
 - Move the struct extcon_cable to extcon core from header file
   because it should be only handled on extcon core.
 - Add the missing of_node_put() after calling of_parse_phandle()
   to decrement the reference count.

f4979fcea7 rose: limit sk_filter trim to payload
Sockets can have a filter program attached that drops or trims
incoming packets based on the filter program return value.

Rose requires data packets to have at least ROSE_MIN_LEN bytes. It
verifies this on arrival in rose_route_frame and unconditionally pulls
the bytes in rose_recvmsg. The filter can trim packets to below this
value in-between, causing pull to fail, leaving the partial header at
the time of skb_copy_datagram_msg.

Place a lower bound on the size to which sk_filter may trim packets
by introducing sk_filter_trim_cap and call this for rose packets.

980e0b36b5 [media] cec: split the timestamp into an rx and tx timestamp
When transmitting a message and waiting for a reply it would be good
to know the time between when the message was transmitted and when
the reply arrived. With only one timestamp field it was set to when
the reply arrived and the original transmit time was overwritten.

Just taking the timestamp in userspace right before CEC_TRANSMIT is
called is not reliable, since the actual transmit can be delayed if
the CEC bus is busy. Only the driver can fill this in accurately.

So split up the ts field into an rx_ts and a tx_ts. Also move the
status fields to after the 'reply' field: they were placed in a
strange position and make much more sense when grouped with the
other status-related fields.

This patch also makes sure that the timestamp is taken as soon as
possible.
