Linus Torvalds a9ceea2674 ARM: 64-bit DT updates
Device-tree updates for arm64 platforms. For the first time I can
 remember, this is actually larger than the corresponding branch for
 32-bit platforms overall, though that has more individual changes.
 
 A significant portion this time is due to added machine support:
 
 - Initial support for the Realtek RTD1295 SoC, along with the Zidoo
   X9S set-top-box
 
 - Initial support for Actions Semi S900 and the Bubblegum-96
   single-board-cёmputer.
 
 - Rockchips support for the rk3399-Firefly single-board-computer
   gets added, this one stands out for being relatively fast,
   affordable and well₋supported, compared to many boards that
   only fall into one or two of the above categories.
 
 - Mediatek gains support for the mt6797 mobile-phone SoC platform
   and corresponding evaluation board.
 
 - Amlogic board support gets added for the NanoPi K2 and S905x
   LibreTech CC single-board computers and the R-Box Pro set-top-box
 
 - Allwinner board support gets added for the OrangePi Win,
   Orangepi Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single
   board computers and the SoPine system-on-module.
 
 - Renesas board support for Salvator-XS and H3ULCB
   automotive development systems.
 
 - Socionext Uniphier board support for LD11-global and LD20-global,
   whatever those may be.
 
 - Broadcom adds support for the new Stingray communication processor
   in its iProc family, along with two reference boards.
 
 Other updates include:
 
 - For the hisicon platform, support for Hi3660-Hikey960 gets
   extended significantly.
 
 - Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier,
   Broadcom, Allwinner, Hisilicon, Qualcomm, Marvell, and NXP.

Linus Torvalds e854711291 ARM: SoC driver updates
- New SoC specific drivers
   - NVIDIA Tegra PM Domain support for newer SoCs (Tegra186 and later)
     based on the "BPMP" firmware
   - Clocksource and system controller drivers for the newly added
     Action Semi platforms (both arm and arm64).
 
 - Reset subsystem, merged through arm-soc by tradition:
   - New drivers for Altera Stratix10, TI Keystone and Cortina Gemini SoCs
   - Various subsystem-wide cleanups
 
 - Updates for existing SoC-specific drivers
   - TI GPMC (General Purpose Memory Controller)
   - Mediatek "scpsys" system controller support for MT6797
   - Broadcom "brcmstb_gisb" bus arbitrer
   - ARM SCPI firmware
   - Renesas "SYSC" system controller
 
 One more driver update was submitted for the Freescale/NXP DPAA
 data path acceleration that has previously been used on PowerPC
 chips. I ended up postponing the merge until some API questions
 for its unusual MMIO access are resolved.

Linus Torvalds 1849f800fb ARM: Device-tree updates
Device-tree continues to see lots of updates. The majority of patches
 here are smaller changes for new hardware on existing platforms, and
 there are a few larger changes worth pointing out.
 
 New machines:
 
 - The new Action Semi S500 platform is added along with initial
   support for the LeMaker Guitar board.
 
 - STM32 gains support for three new boards: stm32h743-disco,
   stm32f746-disco, and stm32f769-disco, along with new device
   support for the existing stm32f429 boards.
 
 - Renesas adds two new boards, the tiny GR-Peach based on RZ/A1H
   with 10MB on-chip SRAM, and the iWave G20D-Q7 System-on-Module
   plus board.
 
 - On Marvell "mvebu", we gain support for the Linksys WRT3200ACM
   wireless router.
 
 - For NXP i.MX, we gain support for the Gateworks Ventana GW5600
   and the Technexion Pico i.MX7D single-board computers.
 
 - The BeagleBone Blue is added for OMAP, it's the latest variation
   of the popular Beaglebone Black single-board computer.
 
 - The Allwinner based Lichee Pi Zero and NanoPi M1 Plus boards
   are added, these are the latest variations of a seemingly endless
   supply of similar single-board computers.
 
 Other updates:
 
 - Linus Walleij improves support for the "Faraday" based SoC platforms
   from various SoC makers (Moxart, Aspeed, Gemini)
 
 - The ARM Mali GPU is now describe on Rockchips SoCs
 
 - Mediatek MT7623 is extended significantly, making it much
   more useful.
 
 - Lots of individual updates on Renesas, OMAP, Rockchips, Broadcom,
   Allwinner, Qualcomm, iMX
 
 - For Amlogic, the clock support is extended a lot on meson8b.
 
 - We now build the devicetree file for the Raspberry Pi 3 on 32-bit
   ARM, in addition to the existing ARM64 support, to help users
   wanting to run a 32-bit system on it.

Linus Torvalds 612341bda6 ARM: SoC non-urgent fixes for merge window
Smaller patches that didn't seem to find a home in other branches, and
 low-priority fixes from late in the merge window.
 
 - Lee Jones retires as bcm2835 (raspberry pi) co-maintainer.
 
 - A couple of bugfixes for the ARM CCN bus driver that were
   regarded not important enough
 
 - minor device tree fixes for the Renesas and Marvell platforms,
   that came a little late or did not justify have another
   pull request after the last -rc.

Linus Torvalds 408c9861c6 Power management updates for v4.13-rc1
- Rework suspend-to-idle to allow it to take wakeup events signaled
    by the EC into account on ACPI-based platforms in order to properly
    support power button wakeup from suspend-to-idle on recent Dell
    laptops (Rafael Wysocki).
 
    That includes the core suspend-to-idle code rework, support for
    the Low Power S0 _DSM interface, and support for the ACPI INT0002
    Virtual GPIO device from Hans de Goede (required for USB keyboard
    wakeup from suspend-to-idle to work on some machines).
 
  - Stop trying to export the current CPU frequency via /proc/cpuinfo
    on x86 as that is inaccurate and confusing (Len Brown).
 
  - Rework the way in which the current CPU frequency is exported by
    the kernel (over the cpufreq sysfs interface) on x86 systems with
    the APERF and MPERF registers by always using values read from
    these registers, when available, to compute the current frequency
    regardless of which cpufreq driver is in use (Len Brown).
 
  - Rework the PCI/ACPI device wakeup infrastructure to remove the
    questionable and artificial distinction between "devices that
    can wake up the system from sleep states" and "devices that can
    generate wakeup signals in the working state" from it, which
    allows the code to be simplified quite a bit (Rafael Wysocki).
 
  - Fix the wakeup IRQ framework by making it use SRCU instead of
    RCU which doesn't allow sleeping in the read-side critical
    sections, but which in turn is expected to be allowed by the
    IRQ bus locking infrastructure (Thomas Gleixner).
 
  - Modify some computations in the intel_pstate driver to avoid
    rounding errors resulting from them (Srinivas Pandruvada).
 
  - Reduce the overhead of the intel_pstate driver in the HWP
    (hardware-managed P-states) mode and when the "performance"
    P-state selection algorithm is in use by making it avoid
    registering scheduler callbacks in those cases (Len Brown).
 
  - Rework the energy_performance_preference sysfs knob in
    intel_pstate by changing the values that correspond to
    different symbolic hint names used by it (Len Brown).
 
  - Make it possible to use more than one cpuidle driver at the same
    time on ARM (Daniel Lezcano).
 
  - Make it possible to prevent the cpuidle menu governor from using
    the 0 state by disabling it via sysfs (Nicholas Piggin).
 
  - Add support for FFH (Fixed Functional Hardware) MWAIT in ACPI C1
    on AMD systems (Yazen Ghannam).
 
  - Make the CPPC cpufreq driver take the lowest nonlinear performance
    information into account (Prashanth Prakash).
 
  - Add support for hi3660 to the cpufreq-dt driver, fix the
    imx6q driver and clean up the sfi, exynos5440 and intel_pstate
    drivers (Colin Ian King, Krzysztof Kozlowski, Octavian Purdila,
    Rafael Wysocki, Tao Wang).
 
  - Fix a few minor issues in the generic power domains (genpd)
    framework and clean it up somewhat (Krzysztof Kozlowski,
    Mikko Perttunen, Viresh Kumar).
 
  - Fix a couple of minor issues in the operating performance points
    (OPP) framework and clean it up somewhat (Viresh Kumar).
 
  - Fix a CONFIG dependency in the hibernation core and clean it up
    slightly (Balbir Singh, Arvind Yadav, BaoJun Luo).
 
  - Add rk3228 support to the rockchip-io adaptive voltage scaling
    (AVS) driver (David Wu).
 
  - Fix an incorrect bit shift operation in the RAPL power capping
    driver (Adam Lessnau).
 
  - Add support for the EPP field in the HWP (hardware managed
    P-states) control register, HWP.EPP, to the x86_energy_perf_policy
    tool and update msr-index.h with HWP.EPP values (Len Brown).
 
  - Fix some minor issues in the turbostat tool (Len Brown).
 
  - Add support for AMD family 0x17 CPUs to the cpupower tool and fix
    a minor issue in it (Sherry Hurwitz).
 
  - Assorted cleanups, mostly related to the constification of some
    data structures (Arvind Yadav, Joe Perches, Kees Cook, Krzysztof
    Kozlowski).

Pull power management updates from Rafael Wysocki:
 "The big ticket items here are the rework of suspend-to-idle in order
  to add proper support for power button wakeup from it on recent Dell
  laptops and the rework of interfaces exporting the current CPU
  frequency on x86.

  In addition to that, support for a few new pieces of hardware is
  added, the PCI/ACPI device wakeup infrastructure is simplified
  significantly and the wakeup IRQ framework is fixed to unbreak the IRQ
  bus locking infrastructure.

  Also, there are some functional improvements for intel_pstate, tools
  updates and small fixes and cleanups all over.

Amir Goldstein 9412812ef5 ovl: document copying layers restrictions with inodes index
The inodes index feature introduces a behavior change - on mount,
upper root origin file handle is verified to match the lower root dir.
This implies that copied layers cannot be mounted with the inodes index
feature enabled, without explicitly removing the upper dir origin xattr
and the index dir.

The inodes index feature is required to support:
- Prevent breaking hardlinks on copy up
- NFS export support (upcoming)
- Overlayfs snapshots (POC)

Linus Torvalds b39de277b0 spi: Updates for v4.13
There's only one big change in this release but it's a very big change,
 Geert Uytterhoeven has implemented support for SPI slave mode.  This
 feature has been on the cards since the subsystem was originally merged
 back in the mists of time so it's great that Geert stepped up and
 finally implemented it.
 
  - SPI slave support, together with wholesale renaming of SPI
    controllers from master to controller which went surprisingly
    smoothly.  This is already used with Renesas SoCs and support is in
    the works for i.MX too.
  - New drivers for Meson SPICC and ST STM32

 reorg, the new mux driver subsystem, google firmware driver updates, and
 a raft of other smaller things.  Full details in the shortlog.
 
 All of these have been in linux-next for a while with the only reported
 issue being a merge problem with this tree and the jc-docs tree in the
 w1 documentation area.  The fix should be obvious for what to do when it
 happens, if not, we can send a follow-up patch for it afterward.

Linus Torvalds cbcd4f08aa Staging/IIO patches for 4.13-rc1
Here's the large set of staging and iio driver patches for 4.13-rc1.
 After over 500 patches, we removed about 200 more lines of code than we
 added, not great, but we added some new IIO drivers for unsupported
 hardware, so it's an overall win.
 
 Also here are lots of small fixes, and some tty core api additions (with
 the tty maintainer's ack) for the speakup drivers, those are finally
 getting some much needed cleanups and are looking much better now than
 before.  Full details in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

Linus Torvalds 362f6729cb USB/PHY patches for 4.13-rc1
Here is the big patchset of USB and PHY driver updates for 4.13-rc1.
 
 On the PHY side, they decided to move files around to "make things
 easier" in their tree.  Hopefully that wasn't a mistake, but in
 linux-next testing, we haven't had any reported problems.
 
 There's the usual set of gadget and xhci and musb updates in here as
 well, along with a number of smaller updates for a raft of different USB
 drivers.  Full details in the shortlog, nothing really major.

Pull irq updates from Thomas Gleixner:
 "The irq department delivers:

   - Expand the generic infrastructure handling the irq migration on CPU
     hotplug and convert X86 over to it. (Thomas Gleixner)

     Aside of consolidating code this is a preparatory change for:

   - Finalizing the affinity management for multi-queue devices. The
     main change here is to shut down interrupts which are affine to a
     outgoing CPU and reenabling them when the CPU comes online again.
     That avoids moving interrupts pointlessly around and breaking and
     reestablishing affinities for no value. (Christoph Hellwig)

     Note: This contains also the BLOCK-MQ and NVME changes which depend
     on the rework of the irq core infrastructure. Jens acked them and
     agreed that they should go with the irq changes.

Dmitry Monakhov e23947bd76 bio-integrity: fold bio_integrity_enabled to bio_integrity_prep
Currently all integrity prep hooks are open-coded, and if prepare fails
we ignore it's code and fail bio with EIO. Let's return real error to
upper layer, so later caller may react accordingly.

In fact no one want to use bio_integrity_prep() w/o bio_integrity_enabled,
so it is reasonable to fold it in to one function.

Linus Torvalds c6b1e36c8f Merge branch 'for-4.13/block' of git://git.kernel.dk/linux-block
Pull core block/IO updates from Jens Axboe:
 "This is the main pull request for the block layer for 4.13. Not a huge
  round in terms of features, but there's a lot of churn related to some
  core cleanups.

  Note this depends on the UUID tree pull request, that Christoph
  already sent out.

  This pull request contains:

   - A series from Christoph, unifying the error/stats codes in the
     block layer. We now use blk_status_t everywhere, instead of using
     different schemes for different places.

   - Also from Christoph, some cleanups around request allocation and IO
     scheduler interactions in blk-mq.

   - And yet another series from Christoph, cleaning up how we handle
     and do bounce buffering in the block layer.

   - A blk-mq debugfs series from Bart, further improving on the support
     we have for exporting internal information to aid debugging IO
     hangs or stalls.

   - Also from Bart, a series that cleans up the request initialization
     differences across types of devices.

   - A series from Goldwyn Rodrigues, allowing the block layer to return
     failure if we will block and the user asked for non-blocking.

   - Patch from Hannes for supporting setting loop devices block size to
     that of the underlying device.

   - Two series of patches from Javier, fixing various issues with
     lightnvm, particular around pblk.

   - A series from me, adding support for write hints. This comes with
     NVMe support as well, so applications can help guide data placement
     on flash to improve performance, latencies, and write
     amplification.

   - A series from Ming, improving and hardening blk-mq support for
     stopping/starting and quiescing hardware queues.

   - Two pull requests for NVMe updates. Nothing major on the feature
     side, but lots of cleanups and bug fixes. From the usual crew.

   - A series from Neil Brown, greatly improving the bio rescue set
     support. Most notably, this kills the bio rescue work queues, if we
     don't really need them.

   - Lots of other little bug fixes that are all over the place"

Peter Feiner 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.

The thin archives build currently puts all lib.a and built-in.o

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.

Commit f8475cef90 "x86: use common aperfmperf_khz_on_cpu() to
calculate KHz using APERF/MPERF" modified the way the scaling_cur_freq
cpufreq policy attribute in sysfs is handled on contemporary
Intel-based x86 systems, so update the documentation to reflect
that change.

Rafael J. Wysocki fab24dcc39 cpufreq: intel_pstate: Clean up after performance governor changes
After commit 82b4e03e01 (intel_pstate: skip scheduler hook when in
"performance" mode) get_target_pstate_use_performance() and
get_target_pstate_use_cpu_load() are never called if scaling_governor
is "performance", so drop the CPUFREQ_POLICY_PERFORMANCE checks from
them as they will never trigger anyway.

Moreover, the documentation needs to be updated to reflect the change
made by the above commit, so do that too.

So we won't miss every point of the good sample windows. However,

Actually we don't need to do tuning for each degree so that we could

Nandor Han 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.

John Stultz 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

Kuninori Morimoto e3839bd6f5 drm: dw-hdmi-i2s: add .get_dai_id callback for ALSA SoC
ALSA SoC needs to know connected DAI ID for probing.
It is not a big problem if device/driver was only for sound,
but getting DAI ID will be difficult if device includes both
Video/Sound, like HDMI.
To solve this issue, this patch adds new .get_dai_id callback
on hdmi_codec_ops.
dw-hdmi-i2s will assume that HDMI sound will be connected
to reg = <2>. Then, ALSA SoC side will recognized it as DAI 0

	ports {
		#address-cells = <1>;
		#size-cells = <0>;
		port@0 {
			reg = <0>;
			/* HDMI Video IN */
		};
		port@1 {
			reg = <1>;
			/* HDMI OUT */
		};
		port@2 {
			reg = <2>;
			/* HDMI Sound IN */
		};
	};

This patch aligns example with the optional property description,
removes status and replace spidev unvalid compatible with
Aarvark SPI Host Adapter one.

In slave mode, Aardvark SPI Host Adapter requires 4ms delay

Tejun Heo 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.

Rafael J. Wysocki 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.

Pantelis Antoniou 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
check. The unittest code was written by Grant Likely.

Please note this binding is designed to be generic and not influenced by
any operating system design. Linux developers may find "trigger" part a

David S. Miller 24a72b77f3 wireless-drivers-next patches for 4.13
New features and bug fixes to quite a few different drivers, but
 nothing really special standing out.
 
 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
 Garzik's "State of the Union: Wireless" email:
 
 https://lkml.org/lkml/2006/1/5/671
 
 Major changes:

 * add low level RF sector interface via nl80211 vendor commands
 
 * add module parameter ftm_mode to load separate firmware for factory
   testing
 
 * support devices with different PCIe bar size
 
 * add support for PCIe D3hot in system suspend
 
 * remove ioctl interface which should not be in a wireless driver

 * go back to using dma_alloc_coherent() for firmware scratch memory
 
 * add per chain RSSI reporting

Tejun Heo 39fd64ae9f cgroup: "cgroup.subtree_control" should be writeable by delegatee
"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.

and PAGE0_REGS_ONLY option is enabled as an errata workaround.
This option when turned on, replaces all page 1 offsets used for
EVTQ_PROD/CONS, PRIQ_PROD/CONS register access with page 0 offsets.

SMMU resource size checks are now based on SMMU option PAGE0_REGS_ONLY,
since resource size can be either 64k/128k.
For this, arm_smmu_device_dt_probe/acpi_probe has been moved before
platform_get_resource call, so that SMMU options are set beforehand.

Thomas Petazzoni f39a29bb5c dt-bindings/interrupt-controller: Add DT binding for the Marvell ICU
This commit adds the Device Tree binding documentation for the Marvell
ICU interrupt controller, which collects wired interrupts from the
devices located into the CP110 hardware block of Marvell Armada 7K/8K,
and converts them into SPI interrupts in the GIC located in the AP
hardware block, using the GICP extension.

Kees Cook 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.

Mark Greer 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.

Chen-Yu Tsai 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.

Masahiro Yamada 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.

Aravinda Prasad 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.]

Ralph Sennhauser 6c7515c61f gpio: mvebu: change compatible string for PWM support
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.

Ingo Molnar ac6424b981 sched/wait: Rename wait_queue_t => wait_queue_entry_t
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',
which is the more canonical nomenclature for such data types.

Damien Le Moal 3b1a94c88b dm zoned: drive-managed zoned block device target
The dm-zoned device mapper target provides transparent write access
to zoned block devices (ZBC and ZAC compliant block devices).
dm-zoned hides to the device user (a file system or an application
doing raw block device accesses) any constraint imposed on write
requests by the device, equivalent to a drive-managed zoned block
device model.

Write requests are processed using a combination of on-disk buffering
using the device conventional zones and direct in-place processing for
requests aligned to a zone sequential write pointer position.
A background reclaim process implemented using dm_kcopyd_copy ensures
that conventional zones are always available for executing unaligned
write requests. The reclaim process overhead is minimized by managing
buffer zones in a least-recently-written order and first targeting the
oldest buffer zones. Doing so, blocks under regular write access (such
as metadata blocks of a file system) remain stored in conventional
zones, resulting in no apparent overhead.

dm-zoned implementation focus on simplicity and on minimizing overhead
(CPU, memory and storage overhead). For a 14TB host-managed disk with
256 MB zones, dm-zoned memory usage per disk instance is at most about
3 MB and as little as 5 zones will be used internally for storing metadata
and performing buffer zone reclaim operations. This is achieved using
zone level indirection rather than a full block indirection system for
managing block movement between zones.

dm-zoned primary target is host-managed zoned block devices but it can
also be used with host-aware device models to mitigate potential
device-side performance degradation due to excessive random writing.

Zoned block devices can be formatted and checked for use with the dm-zoned
target using the dmzadm utility available at:

Hugh Dickins 1be7107fbe mm: larger stack guard gap, between vmas
Stack guard page is a useful feature to reduce a risk of stack smashing
into a different mapping. We have been using a single page gap which
is sufficient to prevent having stack adjacent to a different mapping.
But this seems to be insufficient in the light of the stack usage in
userspace. E.g. glibc uses as large as 64kB alloca() in many commonly
used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX]
which is 256kB or stack strings with MAX_ARG_STRLEN.

This will become especially dangerous for suid binaries and the default
no limit for the stack size limit because those applications can be
tricked to consume a large portion of the stack and a single glibc call
could jump over the guard page. These attacks are not theoretical,
unfortunatelly.

Make those attacks less probable by increasing the stack guard gap
to 1MB (on systems with 4k pages; but make it depend on the page size
because systems with larger base pages might cap stack allocations in
the PAGE_SIZE units) which should cover larger alloca() and VLA stack
allocations. It is obviously not a full fix because the problem is
somehow inherent, but it should reduce attack space a lot.

One could argue that the gap size should be configurable from userspace,
but that can be done later when somebody finds that the new 1MB is wrong
for some special case applications.  For now, add a kernel command line
option (stack_guard_gap) to specify the stack gap size (in page units).

Implementation wise, first delete all the old code for stack guard page:
because although we could get away with accounting one extra page in a
stack vma, accounting a larger gap can break userspace - case in point,
a program run with "ulimit -S -v 20000" failed when the 1MB gap was
counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK
and strict non-overcommit mode.

Instead of keeping gap inside the stack vma, maintain the stack guard
gap as a gap between vmas: using vm_start_gap() in place of vm_start
(or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few
places which need to respect the gap - mainly arch_get_unmapped_area(),
and and the vma tree's subtree_gap support for that.

Ruslan Bilovol 0591bc2360 usb: gadget: add f_uac1 variant based on a new u_audio api
This patch adds a new function 'f_uac1'
(f_uac1 with virtual "ALSA card") that
uses recently created u_audio API. Comparing
to legacy f_uac1 function implementation it
doesn't require any real Audio codec to be
present on the device. In f_uac1 audio
streams are simply sinked to and sourced
from a virtual ALSA sound card created
using u_audio API.

Legacy f_uac1 approach is to write audio
samples directly to existing ALSA sound
card

f_uac1 approach is more generic/flexible
one - create an ALSA sound card that
represents USB Audio function and allows to
be used by userspace application that
may choose to do whatever it wants with the
data received from the USB Host and choose
to provide whatever it wants as audio data
to the USB Host.

f_uac1 also has capture support (gadget->host)
thanks to easy implementation via u_audio.
By default, capture interface has 48000kHz/2ch
configuration, same as playback channel has.

f_uac1 descriptors naming convention
uses f_uac2 driver naming convention that
makes it more common and meaningful.

Comparing to f_uac1_legacy, the f_uac1 doesn't
have volume/mute functionality. This is because
the f_uac1 volume/mute feature unit was dummy
implementation since that driver creation (2009)
and never had any real volume control or mute
functionality, so there is no any difference
here.

Since f_uac1 functionality, exposed
interface to userspace (virtual ALSA card),
input parameters are so different comparing
to f_uac1_legacy, that there is no any
reason to keep them in the same file/module,
and separate function was created.

g_audio can be built using one of existing
UAC functions (f_uac1, f_uac1_legacy or f_uac2)
