The two extcon notifiers are almost the same except for the
variable name for the cable structure and the id notifier inverts
the cable->state logic. Make it the same and replace two
functions with one to save some lines. This also makes it so that
the id cable state is true when the id pin is pulled low, so we
change the name of ->state to ->connected to properly reflect
that we're interested in the cable being connected.

When first implementing support for changing the output frequency, an
optimization was added to continue the PWM after changing the prescaler
without having to reprogram the ON and OFF registers for the duty cycle,
in case the duty cycle stayed the same. This was flawed, because we
compared the absolute value of the duty cycle in nanoseconds instead of
the ratio to the period.
Fix the problem by removing the shortcut.

IPv6 deletes route entries associated with multipath routes on an
admin down where IPv4 does not. For example:
$ ip ro ls vrf red
unreachable default metric 8192
1.1.1.0/24 metric 64
nexthop via 10.100.1.254 dev eth1 weight 1
nexthop via 10.100.2.254 dev eth2 weight 1

$ ip -6 ro ls vrf red

2001:db8:11::/120 via 2001:db8:2::17 dev eth2 metric 1024 pref medium
...
Set link down:
$ ip li set eth1 down
IPv4 retains the multihop route but flags eth1 route as dead:
$ ip ro ls vrf red
unreachable default metric 8192
1.1.1.0/24
nexthop via 10.100.1.16 dev eth1 weight 1 dead linkdown
nexthop via 10.100.2.16 dev eth2 weight 1
10.100.2.0/24 dev eth2 proto kernel scope link src 10.100.2.4
and IPv6 deletes the route as part of flushing all routes for the device:
$ ip -6 ro ls vrf red
2001:db8:2:: dev red proto none metric 0 pref medium
2001:db8:2::/120 dev eth2 proto kernel metric 256 pref medium
2001:db8:11::/120 via 2001:db8:2::17 dev eth2 metric 1024 pref medium
...
Worse, on admin up of the device the multipath route has to be deleted
to get this leg of the route re-added.
This patch keeps routes that are part of a multipath route if
ignore_routes_with_linkdown is set with the dead and linkdown flags
enabling consistency between IPv4 and IPv6:

IBM bit 31 (for the rest of us - bit 0) is a reserved field in the
instruction definition of mtspr and mfspr. Hardware is encouraged to
(and does) ignore it.
As a result, if userspace executes an mtspr DSCR with the reserved bit
set, we get a DSCR facility unavailable exception. The kernel fails to
match against the expected value/mask, and we silently return to
userspace to try and re-execute the same mtspr DSCR instruction. We
loop forever until the process is killed.
We should do something here, and it seems mirroring what hardware does
is the better option vs killing the process. While here, relax the
matching of mfspr PVR too.

The chipidea/udc.c file sends a CI_HDRC_CONTROLLER_RESET_EVENT to

function is not called from chipidea/host.c. And the udc.c file
sends the CI_HDRC_CONTROLLER_STOPPED_EVENT but the host.c file
doesn't do anything.
The intent of the reset event is to allow the wrapper driver to
do any wrapper specific things after the reset bit has been set
in the usb command register. Therefore, add this event hook in
the host role after we toggle that bit.
Similarly, the intent of the stopped event is to allow the
wrapper driver to do any wrapper specific things after the device
is stopped. So when we stop the host role, send the stopped
event.

The qcom HSIC ULPI phy doesn't have any bits set in the vendor or
product ID registers. This makes it impossible to make a ULPI
driver match against the ID registers. Add support to discover
the ULPI phys via DT help alleviate this problem. In the DT case,
we'll look for a ULPI bus node underneath the device registering
the ULPI viewport (or the parent of that device to support
chipidea's device layout) and then match up the phy node
underneath that with the ULPI device that's created.
The side benefit of this is that we can use standard properties
in the phy node like clks, regulators, gpios, etc. because we
don't have firmware like ACPI to turn these things on for us. And
we can use the DT phy binding to point our phy consumer to the
phy provider.
The ULPI bus code supports native enumeration by reading the
vendor ID and product ID registers at device creation time, but
we can't be certain that those register reads will succeed if the
phy is not powered up. To avoid any problems with reading the ID
registers before the phy is powered we fallback to DT matching
when the ID reads fail.
If the ULPI spec had some generic power sequencing for these
registers we could put that into the ULPI bus layer and power up
the device before reading the ID registers. Unfortunately this
doesn't exist and the power sequence is usually device specific.
By having the device matched up with DT we can avoid this
problem.

There is a hidden logic for acpi_tb_install_standard_table() as it can be
invoked from the boot stage and during runtime.
1. When it is invoked from the OS boot stage, the ACPICA mutex may not have
been initialized yet and so acpi_ut_acquire_mutex()/acpi_ut_release_mutex()
are not invoked in these code paths:
acpi_initialize_tables
acpi_tb_parse_root_table
acpi_tb_install_standard_table (4 invocations)
acpi_install_table
acpi_tb_install_standard_table
2. When it is invoked during the runtime, ACPICA mutex is used as
appropriate:
acpi_ex_load_op
acpi_tb_install_and_load_table
acpi_tb_install_standard_table
acpi_load_table
acpi_tb_install_and_load_table
acpi_tb_install_standard_table
The mutex is now used in acpi_tb_install_and_load_table(), while it actually
should be in acpi_tb_install_standard_table().
This introduces another problem in acpi_tb_install_standard_table() where
acpi_gbl_table_handler is invoked from and the lock contexts are thus not
consistent for the table handlers. This triggers a regression when
acpi_get_table()/acpi_put_table() start to hold table mutex during runtime.
The regression is noticed by LKP as new errors reported by ACPICA mutex
debugging facility.

The table mutex is held in acpi_tb_install_and_load_table() and is re-visited by
acpi_get_table().
Noticing that the early mutex requirement actually belongs to the OSL layer
and has already been handled in acpi_os_wait_semaphore()/acpi_os_signal_semaphore(),
the regression canbe fixed by removing this hidden logic from the ACPICA core
to the OS-specific code.

A side effect of keeping intel_pstate sysfs limits in sync with cpufreq
is that the now sysfs limits can't enforced under performance policy.
For example, if the max_perf_pct is changed from 100 to 80, this will call
intel_pstate_set_policy(), which will change the max_perf to 100 again for
performance policy. Same issue happens, when no_turbo is set.
This change calculates max and min frequency using sysfs performance
limits in intel_pstate_verify_policy() and adjusts policy limits by
calling cpufreq_verify_within_limits().
Also, it causes the setting of performance limits to be skipped if
no_turbo is set.

Mike reported that he could trigger the WARN_ON_ONCE() in
set_sched_clock_stable() using hotplug.
This exposed a fundamental problem with the interface, we should never
mark the TSC stable if we ever find it to be unstable. Therefore
set_sched_clock_stable() is a broken interface.
The reason it existed is that not having it is a pain, it means all
relevant architecture code needs to call clear_sched_clock_stable()
where appropriate.
Of the three architectures that select HAVE_UNSTABLE_SCHED_CLOCK ia64
and parisc are trivial in that they never called
set_sched_clock_stable(), so add an unconditional call to
clear_sched_clock_stable() to them.
For x86 the story is a lot more involved, and what this patch tries to
do is ensure we preserve the status quo. So even is Cyrix or Transmeta
have usable TSC they never called set_sched_clock_stable() so they now
get an explicit mark unstable.

Pull xfs fixes from Darrick Wong:
"I have a few more patches this week -- one to make the behavior of a
quota id ioctl consistent with the other filesystems, and the rest
improve validation of i_mode & i_size values coming into xfs so that
we don't read off the ends of arrays or crash when handed garbage disk
data.
Summary:
- inode i_mode sanitization
- prevent overflows in getnextquota
- minor build fixes"
* tag 'xfs-for-linux-4.10-rc5-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
xfs: fix xfs_mode_to_ftype() prototype
xfs: don't wrap ID in xfs_dq_get_next_id
xfs: sanity check inode di_mode
xfs: sanity check inode mode when creating new dentry
xfs: replace xfs_mode_to_ftype table with switch statement
xfs: add missing include dependencies to xfs_dir2.h
xfs: sanity check directory inode di_size

please pull the following changes:
- Rafal enables the UART by default on all BCM5301x, BCM4708, BCM4709 since
every device found out there has it enabled by default. He also fixes the
LED definitions for the Luxul XWR-3100 device, enables USB controllers and
their respective PHY devices, specifies the correct GPIO to power on USB
HUBs, adds the additional RAM bank for somes devices, and finally sets the
correct 5Ghz frequency limits on the Netgear R8000
- Jon does a number of Norsthar Plus SoC cleanups, fixes NAND partitions unit
addresses, adds QSPI support to a bunch of boards, adds Ethernet switch ports
to the BCM958625K reference board, enables 3rd Ethernet MAC instance to
relevant DTSes, enables Ethernet on the XMC board, and finally adds SD/MMC
support to the XMC board
- Boris adds the Video Encoder nodes to the Raspberry Pi DTS include files
ands enables it on the relevant boards
- Dan adds support for two new Luxul devices: XAP-1410 and XWR-1200, both
BCM47081 based SoCs

Read access to the SPI flash are broken on da850-evm, i.e. the data
read is not what is actually programmed on the flash.
According to the datasheet for the M25P64 part present on the da850-evm,
if the SPI frequency is higher than 20MHz then the READ command is not
usable anymore and only the FAST_READ command can be used to read data.
This commit specifies in the DTS that we should use FAST_READ command
instead of the READ command.

Add a cut-down version of the DTS file for the community board
MACCHIATOBin from SolidRun based on Marvell Armada 8040 SoC to suit
the current mainlined Armada 8040 state.
This brings support for mainly SATA, SPI flash and UART. The USB
descriptions are included but are not tested in this form due to the
lack of mainline GPIO.

As virtio-1 introduced the possibility of the device manipulating the

of getting the status byte from the device via READ_STATUS. Let's wire
it up for revisions >= 2 and fall back to returning the stored status
byte if not supported.

Since ef1b144d ("tools/virtio/ringtest: fix run-on-all.sh to work
without /dev/cpu") run-on-all.sh uses seq 0 $HOST_AFFINITY as the list
of ids of the CPUs to run the command on (assuming ids of online CPUs
are consecutive and start from 0), where $HOST_AFFINITY is the highest
CPU id in the system previously determined using lscpu. This can fail
on systems with offline CPUs.
Instead let's use lscpu to determine the list of online CPUs.

Using control_work instead of config_work as the 3rd argument to
container_of results in an invalid portdev pointer. Indeed, the work
structure is initialized as below:
INIT_WORK(&portdev->config_work, &config_work_handler);
It leads to a crash when portdev->vdev is dereferenced later. This
bug
is triggered when the guest uses a virtio-console without multiport
feature and receives a config_changed virtio interrupt.
