ac8d57e573 kvm: x86: mmu: allow A/D bits to be disabled in an mmu
Adds the plumbing to disable A/D bits in the MMU based on a new role
bit, ad_disabled. When A/D is disabled, the MMU operates as though A/D
aren't available (i.e., using access tracking faults instead).

To avoid SP -> kvm_mmu_page.role.ad_disabled lookups all over the
place, A/D disablement is now stored in the SPTE. This state is stored
in the SPTE by tweaking the use of SPTE_SPECIAL_MASK for access
tracking. Rather than just setting SPTE_SPECIAL_MASK when an
access-tracking SPTE is non-present, we now always set
SPTE_SPECIAL_MASK for access-tracking SPTEs.

3a166fc2d4 kbuild: handle libs-y archives separately from built-in.o archives
The thin archives build currently puts all lib.a and built-in.o
files together and links them with --whole-archive.

This works because thin archives can recursively refer to thin
archives. However some architectures include libgcc.a, which may
not be a thin archive, or it may not be constructed with the "P"
option, in which case its contents do not get linked correctly.

So don't pull .a libs into the root built-in.o archive. These
libs should already have symbol tables and indexes built, so they
can be direct linker inputs. Move them out of the --whole-archive
option, which restore the conditional linking behaviour of lib.a
to thin archives builds.

fca0c33003 dt-bindings: rockchip-dw-mshc: add optional rockchip, desired-num-phases
By default, dw_mmc-rockchip will execute tuning for each degree.
So we won't miss every point of the good sample windows. However,
probably the phases are linear inside the good sample window.
Actually we don't need to do tuning for each degree so that we could
save some time, for instance, probe the driver or resume from S3.

a3015affdf serial: imx-serial - move DMA buffer configuration to DT
The size of the DMA buffer can affect the delta time between data being
produced and data being consumed. Basically the DMA system will move
data to tty buffer when a) DMA buffer is full b) serial line is idle.
The situation is visible when producer generates data continuously and
there is no possibility for idle line. At this point the DMA buffer is
directly affecting the delta time.

The patch will add the possibility to configure the DMA buffers in DT,
which case by case can be configured separately for every driver
instance. The DT configuration is optional and in case missing the
driver will use the 4096 buffer with 4 periods (as before), therefore no
clients are impacted by this change.

7204e97685 drm: adv7511_audio: Add .get_dai_id callback to map port number to dai id
ALSA SoC needs to know connected DAI ID for probing. Using
the new audio-card-graph approach, ports/endpoints are used
to describe how the links are connected. Unfortunately, since
ports/endpoints are used as well for video linkages, there
are some issues mixing the port ids to the two (video and
audio) namespaces.

To solve this issue, this patch adds new .get_dai_id callback
on hdmi_codec_ops.

The will assume that HDMI audio out will be connected to
reg = <2>. This will then be remapped to the ALSA SoC side will
as DAI 0. Allowing the adv7511's hdmi audio support to be used
with the audio-card-graph.

5136f6365c cgroup: implement "nsdelegate" mount option
Currently, cgroup only supports delegation to !root users and cgroup
namespaces don't get any special treatments.  This limits the
usefulness of cgroup namespaces as they by themselves can't be safe
delegation boundaries.  A process inside a cgroup can change the
resource control knobs of the parent in the namespace root and may
move processes in and out of the namespace if cgroups outside its
namespace are visible somehow.

This patch adds a new mount option "nsdelegate" which makes cgroup
namespaces delegation boundaries.  If set, cgroup behaves as if write
permission based delegation took place at namespace boundaries -
writes to the resource control knobs from the namespace root are
denied and migration crossing the namespace boundary aren't allowed
from inside the namespace.

This allows cgroup namespace to function as a delegation boundary by
itself.

v2: Silently ignore nsdelegate specified on !init mounts.

de3ef1eb1c PM / core: Drop run_wake flag from struct dev_pm_info
The run_wake flag in struct dev_pm_info is used to indicate whether
or not the device is capable of generating remote wakeup signals at
run time (or in the system working state), but the distinction
between runtime remote wakeup and system wakeup signaling has always
been rather artificial.  The only practical reason for it to exist
at the core level was that ACPI and PCI treated those two cases
differently, but that's not the case any more after recent changes.

For this reason, get rid of the run_wake flag and, when applicable,
use device_set_wakeup_capable() and device_can_wakeup() instead of
device_set_run_wake() and device_run_wake(), respectively.

ce4fecf1fe vsprintf: Add %p extension "%pOF" for device tree
90% of the usage of device node's full_name is printing it out in a
kernel message. However, storing the full path for every node is
wasteful and redundant. With a custom format specifier, we can generate
the full path at run-time and eventually remove the full path from every
node.

For instance typical use is:
	pr_info("Frobbing node %s\n", node->full_name);

Which can be written now as:
	pr_info("Frobbing node %pOF\n", node);

'%pO' is the base specifier to represent kobjects with '%pOF'
representing struct device_node. Currently, struct device_node is the
only supported type of kobject.

More fine-grained control of formatting includes printing the name,
flags, path-spec name and others, explained in the documentation entry.

Originally written by Pantelis, but pretty much rewrote the core
function using existing string/number functions. The 2 passes were
unnecessary and have been removed. Also, updated the checkpatch.pl

80dc6e1cd8 dt-bindings: leds: document new trigger-sources property
Some LEDs can be related to a specific device(s) described in the DT.
This property allows specifying such relations. E.g. USB LED should
usually be used to indicate some USB port(s) state.

Please note this binding is designed to be generic and not influenced by
any operating system design. Linux developers may find "trigger" part a
bit confusing since in Linux triggers are separated drivers. It
shouldn't define the binding though (we shouldn't add an extra level of
indirection).

dd36a2d9ad Second set of IIO new device support, features and cleanups for the 4.13 cycle.
A few reverts here. One was a general failure to notice a device was already
 supported by another driver.  The second is due to a review comment pointing
 out that the original patch was a bad idea and would break existing systems.
 
 Reverts
 * bma180
   - Revert addition of support for the BMA250E it is already supported by
     the bmc150-accel and better supported at that. Oops.
 * hi8435
   - The fix for cleanup of the reset gpio stuff isn't a good way to go.  It
     breaks systems where an inverting level convertor is used.  The right fix
     is to make the original devicetree correct - even if it involves patching
     the devicetree in kernel.
 
 New Device Support
 * stm32-adc
   - STM32H7 support and bindings.
 
 Features
 * core
   - add a hardware triggered operating mode for systems in which the actual
     trigger is never seen by the kernel.  This is typically only used when
     a device 'can' use other triggers, but if a particular magic one is
     enabled the interrupt is effectively handled in hardware and we never see
     it.
 * st-lsm6dsx
   - support active low interrupts.
 * stm32-adc
   - Make the core adc clock optional as not all hardware supported requires it.
   - Make the bus clock optional in the per instance driver as it may be shared
     by all instances of the ADC and is handled by the core.
   - Rework to have a data structure representing the device type specific
     elements.
 * stm32-trigger (and counter)
   - Use the INDIO_HARDWARE_TRIGGERED_MODE where appropriate.
   - Add an attribute to configure device modes for quadrature counting etc.
 
 Clean ups and minor fixes
 * IIO core.
   - use __sysfs_match_string() helper rather than open coding the same.
 * ad7791
   - use sysfs_match_string() helper rather than open coding the same.
 * aspeed-adc
   - handle return value of clk_prepare_enable
 * cpcap
   - Fix default register values and ensure the battery thermistor is enabled
     correctly.
   - Fix the reported die temperature where we can - docs are lacking.
   - Remove the hung interrupt quirk as no longer happens due to fix in the
     mfd driver.
 * hi8435
   - Remove &s from hi8435_info definition as unneeded and inconsistent.
 * hid-sensor-trgger
   - Add kconfig depends on IIO_BUFFER (fixes patch in previous series)
 * ina2xx
   - Make the use of iio_info_mask* elements consistent for all channels.
     This doesn't have any visible effect, but acts as clear documentation of
     which channels various resulting attributes apply to.
 * lpc32xx
   - handle the return value of clk_prepare_enable.
 * meson-saradc
   - NULL instead of 0 for pointer.
 * mma9551
   - use NULL for GPIO connection ID to aid implementation fo ACPI support.
     Here the connection ID doesn't actually tell us anything and it is much
     easier to deal with the driver if it's not there.
 * mpu6050
   - Fix lock issues through use of a local mux.
   - Replace sprintf with scnprintf as appropriate.
   - Check whoami against all known values.  This allows for a small number of
     boards where we are really fishing for the part not being present at all.
     It is unfortunately common to have undescribed changes to use newer chips.
     We paper over this but just emitting a warning for those cases as long as
     we know about.
 * mxs-lradc
   - Fix some non static warnings.
 * rcar-adc
   - Part of making the naming for this part consistent across the kernel.
 * st_accel
   - drop some spi_device_id entries for variants with no SPI support
 * st_magn
   - drop some spi_device_id entries for variants with no SPI support.
 * sx9500
   - Use devm_gpiod_get instead of indexed value with an index of 0 on all
     occasions.
 * twl4030
   - Drop unused twl4030_get_madc_conversion as callers removed now throughout
     kernel.
   - Unexport twl4030_madc_conversion() as no used only within this driver.
   - Drop twl4030_madc_user_params as not used now.
   - Drop twl4030_madc_request.func_cb as not used now.
   - Fold the twl4030-madc.h header into the driver as no longer used anywhere
     else in the kernel.
 * xilinx
   - Handle the return value of clk_prepare_enable

 What makes me happy that we have now more vendors actively
 contributing to upstream drivers. In this pull request we have patches
 from Broadcom, Intel, Qualcomm, Realtek and Redpine Signals, and I
 still have patches from Marvell and Quantenna pending in patchwork. Now
 that's something comparing to how things looked 11 years ago in Jeff

"cgroup.subtree_control" determines which resource types a cgroup
wants to control.  Unlike actual resource knobs, this is an attribute
which belongs to the cgroup itself instead of its parent and thus
should be writeable by the delegatee in a delegated cgroup.

Warning (unit_address_vs_reg): Node /opp_table0/opp@1000000000 has a
unit name, but no reg property

Fix this by replacing '@' with '-' as the OPP nodes will never have a
"reg" property.

313dd1b629 gcc-plugins: Add the randstruct plugin
This randstruct plugin is modified from Brad Spengler/PaX Team's code
in the last public patch of grsecurity/PaX based on my understanding
of the code. Changes or omissions from the original code are mine and
don't reflect the original grsecurity/PaX code.

The randstruct GCC plugin randomizes the layout of selected structures
at compile time, as a probabilistic defense against attacks that need to
know the layout of structures within the kernel. This is most useful for
"in-house" kernel builds where neither the randomization seed nor other
build artifacts are made available to an attacker. While less useful for
distribution kernels (where the randomization seed must be exposed for
third party kernel module builds), it still has some value there since now
all kernel builds would need to be tracked by an attacker.

In more performance sensitive scenarios, GCC_PLUGIN_RANDSTRUCT_PERFORMANCE
can be selected to make a best effort to restrict randomization to
cacheline-sized groups of elements, and will not randomize bitfields. This
comes at the cost of reduced randomization.

Two annotations are defined,__randomize_layout and __no_randomize_layout,
which respectively tell the plugin to either randomize or not to
randomize instances of the struct in question. Follow-on patches enable
the auto-detection logic for selecting structures for randomization
that contain only function pointers. It is disabled here to assist with
bisection.

Since any randomized structs must be initialized using designated
initializers, __randomize_layout includes the __designated_init annotation
even when the plugin is disabled so that all builds will require
the needed initialization. (With the plugin enabled, annotations for
automatically chosen structures are marked as well.)

The main differences between this implemenation and grsecurity are:
- disable automatic struct selection (to be enabled in follow-up patch)
- add designated_init attribute at runtime and for manual marking
- clarify debugging output to differentiate bad cast warnings
- add whitelisting infrastructure
- support gcc 7's DECL_ALIGN and DECL_MODE changes (Laura Abbott)
- raise minimum required GCC version to 4.7

Earlier versions of this patch series were ported by Michael Leibowitz.

a81d1ab3ca Revert "NFC: trf7970a: Handle extra byte in response to Type 5 RMB commands"
This reverts commit ab714817d7.

The original commit was designed to handle a bug in the trf7970a NFC
controller where an extra byte was returned in Read Multiple Blocks (RMB)
command responses.  However, it has become less clear whether it is a bug
in the trf7970a or in the tag.  In addition, it was assumed that the extra
byte was always returned but it turns out that is not always the case. The
result is that a byte of good data is trimmed off when the extra byte is
not present ultimately causing the neard deamon to fail the read.

Since the trf7970a driver does not have the context to know when to trim
the byte or not, remove the code from the trf7970a driver all together
(and move it up to the neard daemon).  This has the added benefit of
simplifying the kernel driver and putting the extra complexity into
userspace.

cd647575ac dt-bindings/interrupt-controller: sunxi-nmi: Add compatible for A31 R_INTC
The A31 and later have an R_INTC block which handles the NMI interrupt
pin on the SoC. This interrupt pin is used by the external PMIC to
signal interrupts to the SoC.

While this hardware block is undocumented, the interrupt offsets
combined with the register regions for the existing "sun6i-a31-sc-nmi"
compatible line up with the old interrupt controller found on the A10.
Experiments show that only the first 32 interrupt lines can be enabled,
and only the first (NMI) interrupt is actually connected.

This patch adds a new, properly named compatible for the A31 R_INTC
block, which requires the register region to be properly aligned to
the block boundary. For comparison, the old "sun6i-a31-sc-nmi"
compatible had its register region aligned with the first used
register. This didn't match up with the memory map in the SoC's
datasheet/user manual.

Since the new compatible supercedes the old one, deprecate the old one.

In some cases, userspace needs to get or set all ais states for example
migration. So we introduce a new group KVM_DEV_FLIC_AISM_ALL to provide
interfaces to get or set the adapter-interruption-suppression mode for
all ISCs. The corresponding documentation is updated.

2ed4f9dd19 KVM: PPC: Book3S HV: Add capability to report possible virtual SMT modes
Now that userspace can set the virtual SMT mode by enabling the
KVM_CAP_PPC_SMT capability, it is useful for userspace to be able
to query the set of possible virtual SMT modes.  This provides a
new capability, KVM_CAP_PPC_SMT_POSSIBLE, to provide this
information.  The return value is a bitmap of possible modes, with
bit N set if virtual SMT mode 2^N is available.  That is, 1 indicates
SMT1 is available, 2 indicates that SMT2 is available, 3 indicates
that both SMT1 and SMT2 are available, and so on.

ae3f415173 kbuild: replace genhdr-y with generated-y
Originally, generated-y and genhdr-y had different meaning, like
follows:

- generated-y: generated headers (other than asm-generic wrappers)
- header-y   : headers to be exported
- genhdr-y   : generated headers to be exported (generated-y + header-y)

Since commit fcc8487d47 ("uapi: export all headers under uapi
directories"), headers under UAPI directories are all exported.
So, there is no more difference between generated-y and genhdr-y.

We see two users of genhdr-y, arch/{arm,x86}/include/uapi/asm/Kbuild.
They generate some headers in arch/{arm,x86}/include/generated/uapi/asm
directories, which are obviously exported.

Replace them with generated-y, and abolish genhdr-y.

or in conjunction with the "ima_appraise_tcb" policy, by specifing
ima_policy="appraise_tcb | secure_boot".  The new appraisal rules

134764ed6e KVM: PPC: Book3S HV: Add new capability to control MCE behaviour
This introduces a new KVM capability to control how KVM behaves
on machine check exception (MCE) in HV KVM guests.

If this capability has not been enabled, KVM redirects machine check
exceptions to guest's 0x200 vector, if the address in error belongs to
the guest. With this capability enabled, KVM will cause a guest exit
with the exit reason indicating an NMI.

The new capability is required to avoid problems if a new kernel/KVM
is used with an old QEMU, running a guest that doesn't issue
"ibm,nmi-register".  As old QEMU does not understand the NMI exit
type, it treats it as a fatal error.  However, the guest could have
handled the machine check error if the exception was delivered to
guest's 0x200 interrupt vector instead of NMI exit in case of old
QEMU.

[paulus@ozlabs.org - Reworded the commit message to be clearer,
 enable only on HV KVM.]

As it turns out more than just Armada 370 and XP support using GPIO
lines as PWM lines. For example the Armada 38x family has the same
hardware support. As such "marvell,armada-370-xp-gpio" for the
compatible string is a misnomer.

Change the compatible string to "marvell,armada-370-gpio" before the
driver makes it out of the -rc stage. This also follows the practice of
using only the first device family supported as part of the name.

Also update the documentation and comments in the code accordingly.

Rename:

	wait_queue_t		=>	wait_queue_entry_t

'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue",
but in reality it's a queue *entry*. The 'real' queue is the wait queue head,
which had to carry the name.

Start sorting this out by renaming it to 'wait_queue_entry_t'.

This also allows the real structure name 'struct __wait_queue' to
lose its double underscore and become 'struct wait_queue_entry',

A simpler variant of cec_transmit_done to be used where the HW does
just a single attempt at a transmit. So if the status indicates an
error, then the corresponding error count will always be 1 and this
function figures that out based on the status argument.
