Pull "Second Round of Renesas ARM64 Based SoC DT Updates for v4.14" from Simon Horman:
* Add PFC device node to R-Car D3 (r8a77995)
This is a step towards enabling devices that use multiplexed pins
- including ethernet - on boards that use the r8a7796 SoC.
* Add USB nodes to R-Car M3-W (r8a7796)
This is a step towards enabling USB devices on boards that
use the r8a7796 SoC.
* Use newly added Gen-3 fallback compat string
This is consistent with ongoing efforts to use per-generation
fallback strings where appropriate across devices found
on R-Car SoCs. The aim of the effort being to strike a balance
between the limited information available about the compatibility
of devices found on different SoCs and the desire to ease enabling
devices on new SoCs.
This has no run-time effect due to the presence of a per-SoC
compat string.
* Cleanup whitespace and extra LVDS port label
Minor cleanups, no run-time effect.

* Enable second CPU core on RZ/G1M (r8a7743)
The RZ/G1M has two CA15 cores running at up to 1.5GHz
* Enable frequency scaling on RZ/G1M (r8a7743)
* Add six I2C cores to RZ/G1M (r8a7743) SoC DT
This is a step towards enabling these cores on boards that use this SoC
* Add CEC clock for HDMI transmitter to R-Car M2-W (r8a7791) Koelsch
Hans Verkuil says "The adv7511 on the Koelsch board has a 12 MHz fixed
clock for the CEC block. Specify this in the dts to enable CEC support."
* Add PFC support to RZ/G1E (r8a7745) SoC and add Ethernet and SCIF2
pins to SK-RZG1E board.
This allows the kernel to control multiplexed pins for Ethernet
and SCIF2 rather than relying on setup inherited at boot.

- Eric moves the bcm2837 DT file from arm64 to arm because it created a maintenance

- Stefan changes how the pinmuxing is defined and pushes it at the board level
to support Raspberry Pi Zero Wireless. He then adds supports for the actual
Raspberry Pi Zero Wireless board along with binding documentation. Stefan
also defines a proper SMP enable-method property and binding for BCM2836

it becomes possible to assign them to specific LED triggers (e.g: USB activity).
He does the same thing for BCM53573 and defines default LED triggers for USB.
- Jon provides a fix for Northstar Plus which consists in correctly defining
the "dma-coherent" property for peripherals which are DMA coherent. He also
does a bit of re-arrangement of the USB DT nodes and finally adds USB 3 PHY
and host controller support for NorthStar Plus
- Florian adds support for Broadcom's BCM947189ACDBMR reference board which is
based on BCM47182/53573 and which supports external MoCA (BCM6802)

- Renesas Salvador Audio support (added in v4.5) was broken for
device repeated bind/unbind due to a naming conflict.

There is currently some confusion between nested and L1 GPAs. The
assignment to "direct" in kvm_mmu_page_fault tries to fix that, but
it is not enough. What this patch does is fence off the MMIO cache
completely when using shadow nested page tables, since we have neither
a GVA nor an L1 GPA to put in the cache. This also allows some
simplifications in kvm_mmu_page_fault and FNAME(page_fault).
The EPT misconfig likewise does not have an L1 GPA to pass to
kvm_io_bus_write, so that must be skipped for guest mode.

When a guest causes a page fault which requires emulation, the
vcpu->arch.gpa_available flag is set to indicate that cr2 contains a
valid GPA.
Currently, emulator_read_write_onepage() makes use of gpa_available flag
to avoid a guest page walk for a known MMIO regions. Lets not limit
the gpa_available optimization to just MMIO region. The patch extends
the check to avoid page walk whenever gpa_available flag is set.

The hardlockup detector on x86 uses a performance counter based on unhalted
CPU cycles and a periodic hrtimer. The hrtimer period is about 2/5 of the
performance counter period, so the hrtimer should fire 2-3 times before the
performance counter NMI fires. The NMI code checks whether the hrtimer
fired since the last invocation. If not, it assumess a hard lockup.
The calculation of those periods is based on the nominal CPU
frequency. Turbo modes increase the CPU clock frequency and therefore
shorten the period of the perf/NMI watchdog. With extreme Turbo-modes (3x
nominal frequency) the perf/NMI period is shorter than the hrtimer period
which leads to false positives.
A simple fix would be to shorten the hrtimer period, but that comes with
the side effect of more frequent hrtimer and softlockup thread wakeups,
which is not desired.
Implement a low pass filter, which checks the perf/NMI period against
kernel time. If the perf/NMI fires before 4/5 of the watchdog period has
elapsed then the event is ignored and postponed to the next perf/NMI.
That solves the problem and avoids the overhead of shorter hrtimer periods
and more frequent softlockup thread wakeups.

RK3399 USB DWC3 controller has a issue that FS/LS devices not
recognized if inserted through USB 3.0 HUB. It's because that
the inter-packet delay between the SSPLIT token to SETUP token
is about 566ns, more then the USB spec requirement.
This patch adds a quirk "snps,dis-tx-ipgap-linecheck-quirk" to
disable the u2mac linestate check to decrease the SSPLIT token
to SETUP token inter-packet delay from 566ns to 466ns.

There is no guarantee that the various isync's involved with
the context switch will order the update of the CPU mask with
the first TLB entry for the new context being loaded by the HW.
Be safe here and add a memory barrier to order any subsequent
load/store which may bring entries into the TLB.
The corresponding barrier on the other side already exists as
pte updates use pte_xchg() which uses __cmpxchg_u64 which has
a sync after the atomic operation.

Pull power management fixes from Rafael Wysocki:
"These fix two issues related to exposing the current CPU frequency to
user space on x86.
Specifics:
- Disable interrupts around reading IA32_APERF and IA32_MPERF in
aperfmperf_snapshot_khz() (introduced recently) to avoid excessive
delays between the reads that may result from interrupt handling
(Doug Smythies).
- Fix the computation of the CPU frequency to be reported through the
pstate_sample tracepoint in intel_pstate (Doug Smythies)"
