Mahesh Salgaonkar a4e92ce8e4 powerpc/fadump: Reservationless firmware assisted dump
One of the primary issues with Firmware Assisted Dump (fadump) on Power
is that it needs a large amount of memory to be reserved. On large
systems with TeraBytes of memory, this reservation can be quite
significant.

In some cases, fadump fails if the memory reserved is insufficient, or
if the reserved memory was DLPAR hot-removed.

In the normal case, post reboot, the preserved memory is filtered to
extract only relevant areas of interest using the makedumpfile tool.
While the tool provides flexibility to determine what needs to be part
of the dump and what memory to filter out, all supported distributions
default this to "Capture only kernel data and nothing else".

We take advantage of this default and the Linux kernel's Contiguous
Memory Allocator (CMA) to fundamentally change the memory reservation
model for fadump.

Instead of setting aside a significant chunk of memory nobody can use,
this patch uses CMA instead, to reserve a significant chunk of memory
that the kernel is prevented from using (due to MIGRATE_CMA), but
applications are free to use it. With this fadump will still be able
to capture all of the kernel memory and most of the user space memory
except the user pages that were present in CMA region.

Essentially, on a P9 LPAR with 2 cores, 8GB RAM and current upstream:
[root@zzxx-yy10 ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           7557         193        6822          12         541        6725
Swap:          4095           0        4095

With this patch:
[root@zzxx-yy10 ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           8133         194        7464          12         475        7338
Swap:          4095           0        4095

Changes made here are completely transparent to how fadump has
traditionally worked.

Thanks to Aneesh Kumar and Anshuman Khandual for helping us understand
CMA and its usage.

- Handle case where CMA reservation spans nodes.

Intel Wired LAN Driver Updates 2018-12-20

This series contains updates to e100, igb, ixgbe, i40e and ice drivers.

I replaced spinlocks for mutex locks to reduce the latency on CPU0 for
igb when updating the statistics.  This work was based off a patch
provided by Jan Jablonsky, which was against an older version of the igb
driver.

Jesus adjusts the receive packet buffer size from 32K to 30K when
running in QAV mode, to stay within 60K for total packet buffer size for
igb.

Vinicius adds igb kernel documentation regarding the CBS algorithm and
its implementation in the i210 family of NICs.

YueHaibing from Huawei fixed the e100 driver that was potentially
passing a NULL pointer, so use the kernel macro IS_ERR_OR_NULL()
instead.

Konstantin Khorenko fixes i40e where we were not setting up the
neigh_priv_len in our net_device, which caused the driver to read beyond
the neighbor entry allocated memory.

Miroslav Lichvar extends the PTP gettime() to read the system clock by
adding support for PTP_SYS_OFFSET_EXTENDED ioctl in i40e.

Young Xiao fixed the ice driver to only enable NAPI on q_vectors that
actually have transmit and receive rings.

Kai-Heng Feng fixes an igb issue that when placed in suspend mode, the
NIC does not wake up when a cable is plugged in.  This was due to the
driver not setting PME during runtime suspend.

Stephen Douthit enables the ixgbe driver allow DSA devices to use the
MII interface to talk to switches.

This adds new dt entry ext-fem-name, it is used by ath10k driver

The Front End Module(FEM) normally includes tx power amplifier(PA) and
rx low noise amplifier(LNA). The default timing parameters like tx end to
PA off timing values were fine tuned for internal FEM used in reference
design. And these timing values can not be same if ODM modifies hardware
design with different external FEM. This DT entry helps to choose correct
timing values in driver if different external FEM hardware used.

Chen-Yu Tsai 31f20f5f6d dt-bindings: net: broadcom-bluetooth: Add BCM4330 compatible string
The BCM4330 is a 802.11 a/b/g/n WiFi + Bluetooth 4.0 chip from Broadcom.
It is found in the Ampak AP6330 WiFi+BT module. The partiular one I have
identifies as BCM4330B1 for Bluetooth and BCM4330/4 for WiFi.

It is unclear if the AP6330 module uses this revision of the BCM4330, or
if there are multiple revisions. The module does not have revision
markings. This patch elects to use just BCM4330 for the compatible
string.

Chen-Yu Tsai 6ae81eebde dt-bindings: net: broadcom-bluetooth: Fix external clock names
The Broadcom Bluetooth controllers can take up to two external clocks:
an external frequency reference, substituting the main crystal, and a
LPO clock at 32.768 kHz substituting the internal LPO clock.

In particular, the external LPO clock must be used when the controller
does not have NVRAM connected, and the main reference frequency is not
the default 20 MHz. This is described in detail in the datasheet.

The original "extclk" clock name is ambiguous as to which of these it
refers to, and some designs might even require both.

This patch deprecates the existing name, and adds "txco" and "lpo".

From Mimi:

In Linux 4.19, a new LSM hook named security_kernel_load_data was
upstreamed, allowing LSMs and IMA to prevent the kexec_load
syscall.  Different signature verification methods exist for verifying
the kexec'ed kernel image.  This pull request adds additional support
in IMA to prevent loading unsigned kernel images via the kexec_load
syscall, independently of the IMA policy rules, based on the runtime
"secure boot" flag.  An initial IMA kselftest is included.

In addition, this pull request defines a new, separate keyring named
".platform" for storing the preboot/firmware keys needed for verifying
the kexec'ed kernel image's signature and includes the associated IMA
kexec usage of the ".platform" keyring.

(David Howell's and Josh Boyer's patches for reading the
preboot/firmware keys, which were previously posted for a different
use case scenario, are included here.)

Darwin Dingel bdb48e4c7d dt-bindings: serial: 8250: Add rate limit for serial port input overruns
When a serial port continuously experiences input overrun from
(1) continuous receive characters from remote and or (2) hardware
issues, its interrupt handler can preempt other tasks especially
when the system is busy (ie. boot up period). This can cause other
tasks to get starved of processing time from the CPU.

When this dts binding is enabled and input overrun on the serial port
is detected, serial port receive will be throttled to give some breathing

Commit 26a4f38d13 ("dt-bindings: mmc: sdhci-of-arasan: Add new
compatible for AM654 MMC PHY") added a new compatible for supporting
controllers on TI's AM65x SOCs. It turns out that the controller is
not compatible with the arasan driver's phy and consumer model as it
requires some phy registers for core sdhci functionality. This calls
for the binding to branch out to a new driver.

Therefore, add a deprecated message for the ti,am654-sdhci-5.1 binding.

Vitaly Kuznetsov 2bc39970e9 x86/kvm/hyper-v: Introduce KVM_GET_SUPPORTED_HV_CPUID
With every new Hyper-V Enlightenment we implement we're forced to add a
KVM_CAP_HYPERV_* capability. While this approach works it is fairly
inconvenient: the majority of the enlightenments we do have corresponding
CPUID feature bit(s) and userspace has to know this anyways to be able to
expose the feature to the guest.

Add KVM_GET_SUPPORTED_HV_CPUID ioctl (backed by KVM_CAP_HYPERV_CPUID, "one
cap to rule them all!") returning all Hyper-V CPUID feature leaves.

Using the existing KVM_GET_SUPPORTED_CPUID doesn't seem to be possible:
Hyper-V CPUID feature leaves intersect with KVM's (e.g. 0x40000000,
0x40000001) and we would probably confuse userspace in case we decide to
return these twice.

KVM_CAP_HYPERV_CPUID's number is interim: we're intended to drop
KVM_CAP_HYPERV_STIMER_DIRECT and use its number instead.

ASoC: q6asm-dai: dt-bindings: Add support to compress dais
This patch adds board specific bindings required for dais, In particular
for compressed dais and dai direction.

Board specific setup involves setting up some of dais as compressed dais
and also specify direction of any dai. Some of the dais might only
support capture/playback depending on the board level wiring.

These two new dt properties will allow such flexibilty at board level dts.

Paolo Bonzini 2a31b9db15 kvm: introduce manual dirty log reprotect
There are two problems with KVM_GET_DIRTY_LOG.  First, and less important,
it can take kvm->mmu_lock for an extended period of time.  Second, its user
can actually see many false positives in some cases.  The latter is due
to a benign race like this:

  1. KVM_GET_DIRTY_LOG returns a set of dirty pages and write protects
     them.
  2. The guest modifies the pages, causing them to be marked ditry.
  3. Userspace actually copies the pages.
  4. KVM_GET_DIRTY_LOG returns those pages as dirty again, even though
     they were not written to since (3).

This is especially a problem for large guests, where the time between
(1) and (3) can be substantial.  This patch introduces a new
capability which, when enabled, makes KVM_GET_DIRTY_LOG not
write-protect the pages it returns.  Instead, userspace has to
explicitly clear the dirty log bits just before using the content
of the page.  The new KVM_CLEAR_DIRTY_LOG ioctl can also operate on a
64-page granularity rather than requiring to sync a full memslot;
this way, the mmu_lock is taken for small amounts of time, and
only a small amount of time will pass between write protection
of pages and the sending of their content.

model to control the clock gates for the peripherals. An LPCG module
is used to locally gate the clocks for the associated peripheral.

Note:
This level of clock gating is provided after the clocks are generated
by the SCU resources and clock controls. Thus even if the clock is
enabled by these control bits, it might still not be running based
on the base resource.

Access to GICR_WAKER is restricted on msm8996 SoC in Hypervisor.
There are many devices out there with this restriction in place
and there has been no update to this firmware since last few years,
making those devices totally unusable for upstream development.

IIDR register value conflicts with other SoCs, using compatible seems
to be the only way to apply quirks required for msm8996 based SoCs.

Without this quirk many qcom SoCs (atleast 3 that I know) are
unable to boot mainline.

dt-bindings: mfd: axp20x: Add software based soft_start for AXP209 LDO3
In the past, there have been words on various lists that if LDO3 is
disabled in u-boot, but enabled in the DTS, the axp209 driver would
fail to continue/hang. Several enable/disable patches have been
issues to devicetree's in both the kernel and u-boot to address
this issue.

What really happened however, was that the AXP209 shuts down without
a notice and without setting an interrupt. This is caused when LDO3
gets overloaded, for example with large capacitors on the LDO3 output.

Normally, we would expect that AXP209 would source 200 mA as per
datasheet and set and trigger an interrupt when being overloaded.
For some reason however, this does not happen.

As a work-around, implement software-based 'regulator-soft-start'
property for AXP209 LDO3 regulator, which is used to first bring up
the LDO3 to the lowest possible voltage and then enable the LDO.

After that, we can set the requested voltage as usual.

Combining this setting with the regulator-ramp-delay allows LDO3 to
come up slowly and staggered, potentially reducing overall inrush current.

dt-bindings: mfd: axp20x: add support for regulator-ramp-delay for AXP209
The AXP209 supports ramping up voltages on several regulators such as
DCDC2 and LDO3, therefore we can use the standard 'regulator-ramp-delay'
property for those 2 regulators.

Note that the voltage ramp only works when the regulator is already
enabled. E.g. when going from say 0.7 V to 3.6 V.

When turning on the regulator, no voltage ramp is performed in hardware.

What this means, is that if the bootloader brings up the voltage at 0.7 V,
the ramp delay property is properly applied. If however, the bootloader
leaves the power off, no ramp delay is applied when the power is
enabled by the regulator framework.

Add a how-to doc on writing DT schema documentation. This gives a
description of each section and details on how to validate the DT schema
file. The DT schema are written using json-schema vocabulary in a YAML
encoded document. Using jsonschema gives us access to existing tooling.
A YAML encoding gives us something easy to edit. The example is
annotated to help explain what each section does.

This example is just the tip of the iceberg, but is it the part most
developers writing bindings will interact with. Backing all this up
are meta-schema (to validate the binding schemas), some DT core schema,
YAML encoded DT output with dtc, and a small number of python scripts to
run validation.

This adds the build infrastructure for checking DT binding schema
documents and validating dts files using the binding schema.

Check DT binding schema documents:
make dt_binding_check

Build dts files and check using DT binding schema:
make dtbs_check

Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to
use for validation. This makes it easier to find and fix errors
generated by a specific schema.

Currently, the validation targets are separate from a normal build to
avoid a hard dependency on the external DT schema project and because
there are lots of warnings generated.

   staging, don't apply the MPEG controls as part of the main V4L2 API,
   as those may not be ready for production yet.

Rafael J. Wysocki 04dab58a39 cpuidle: Add 'above' and 'below' idle state metrics
Add two new metrics for CPU idle states, "above" and "below", to count
the number of times the given state had been asked for (or entered
from the kernel's perspective), but the observed idle duration turned
out to be too short or too long for it (respectively).

These metrics help to estimate the quality of the CPU idle governor
in use.
