Linus Torvalds 738b04fba1 Staging/IIO patches for 4.20-rc1
Here is the big staging and IIO driver pull request for 4.20-rc1.
 
 There are lots of things here, we ended up adding more lines than
 removing, thanks to a large influx of Comedi National Instrument device
 support.  Someday soon we need to get comedi out of staging...
 
 Other than the comedi drivers, the "big" things here are:
   - new iio drivers
   - delete dgnc driver (no one used it and no one had the hardware
     anymore)
   - vbox driver updates and fixes
   - erofs fixes
   - tons and tons of tiny checkpatch fixes for almost all staging
     drivers
 
 All of these have been in linux-next, with the last few happening a bit
 "late" due to them getting stuck on my laptop during travel to the
 Mantainers summit.
 
 When merging with your tree, there will be 2 merge conflicts, both files
 will be simple to resolve, just delete them :)

Linus Torvalds d6edff78fe f2fs-for-4.20-rc1
In this round, we've added 1) superblock checksum feature, 2) implemented new
 mount option which we can disable/enable checkpoint to provide atomic updates of
 entire filesystem, 3) refactored quota operations to enhance its consistency
 along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward
 recovery flow to resurrect any fsync'ed inode metadata.
 
 Enhancement:
  - add checksum to keep superblock contents more safe
  - add checkpoint=disable/enable to support A/B update of entire filesystem
  - use plug for readahead IO in readdir
  - add more IO counts to avoid block layer hacks
 
 Bug fix:
  - prevent data corruption issue for hardware encryption
  - fix IO hang issues when GC is heavily triggered
  - add missing up_read in __write_node_page
  - recover inode metadata during roll-forward recovery flow
  - fix null pointer dereference issue in wrongly configured discard map
 
 There are some more sanity checks and minor bug fixes as well.

Jon Flatley 201af55da8 usb: core: added uevent for over-current
After commit 1cbd53c8cd ("usb: core: introduce per-port over-current
counters") usb ports expose a sysfs value 'over_current_count'
to user space. This value on its own is not very useful as it requires
manual polling.

As a solution, fire a udev event from the usb hub device that specifies
the values 'OVER_CURRENT_PORT' and 'OVER_CURRENT_COUNT' that indicate
the path of the usb port where the over-current event occurred and the
value of 'over_current_count' in sysfs. Additionally, call
sysfs_notify() so the sysfs value supports poll().

Joel Pepper b206548be6 usb: gadget: uvc: configfs: Add bFrameIndex attributes
- Add bFrameIndex as a UVCG_FRAME_ATTR_RO for each frame size.
- Automatically assign ascending bFrameIndex to each frame in a format.

Before all "bFrameindex" attributes were set to "1" with no way to
configure the gadget otherwise. This resulted in the host always
negotiating for bFrameIndex 1 (i.e. the first frame size of the gadget).
After the negotiation the host driver will set the user or application
selected frame size, while the gadget is actually set to the first frame
size.

Now, when the containing format is linked into the streaming header,
iterate over all child frame descriptors and assign ascending indices.
The automatically assigned indices can be read from the new read only
bFrameIndex configfs attribute in each frame descriptor item.

Laurent Pinchart 61ff10e0ea usb: gadget: uvc: configfs: Add bFormatIndex attributes
The UVC format description are numbered using the descriptor's
bFormatIndex field. The index is used in UVC requests, and is thus
needed to handle requests in userspace. Make it dynamically discoverable
by exposing it in a bFormatIndex configfs attribute of the uncompressed
and mjpeg format config items.

The bFormatIndex value exposed through the attribute is stored in the
config item private data. However, that value is never set: the driver
instead computes the bFormatIndex value when linking the stream class
header in the configfs hierarchy and stores it directly in the class
descriptors in a separate structure. In order to expose the value
through the configfs attribute, store it in the config item private data
as well. This results in a small code simplification.

Marek Marczykowski-Górecki 197ecb3802 xen/balloon: add runtime control for scrubbing ballooned out pages
Scrubbing pages on initial balloon down can take some time, especially
in nested virtualization case (nested EPT is slow). When HVM/PVH guest is
started with memory= significantly lower than maxmem=, all the extra
pages will be scrubbed before returning to Xen. But since most of them
weren't used at all at that point, Xen needs to populate them first
(from populate-on-demand pool). In nested virt case (Xen inside KVM)
this slows down the guest boot by 15-30s with just 1.5GB needed to be
returned to Xen.

Add runtime parameter to enable/disable it, to allow initially disabling
scrubbing, then enable it back during boot (for example in initramfs).
Such usage relies on assumption that a) most pages ballooned out during
initial boot weren't used at all, and b) even if they were, very few
secrets are in the guest at that time (before any serious userspace
kicks in).
Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also
enabled by default), controlling default value for the new runtime
switch.

Greg Kroah-Hartman 4b55dce8b0 1st round of IIO new device support, features and cleanups in the 4.20 cycle.
There is a merge commit in here to pull in regmap support for repeatedly
 reading the same register (to read out FIFOs).  Used by the adxl372 driver.
 This will find uses elsewhere once we tidy up various drivers that are
 effectively doing this and relying on not enabling regcache.
 
 New device support
 * Analog devices ADXL372 accelerometer
   - new driver for this accelerometer including fifo and and interrupt support.
     Follow up patches enforce trigger validation, add sampling frequency
     control and filter bandwidth control.  A later series added i2c support
     to the existing SPI support.
 * ST lsm6dsx
   - rework and add support fo the LSM6DSO 6 axis mems sensor.
 * Linear LTC 1660 DAC
   - new driver supporting the LTC 1660 and LTC 1665 SPI DACs.
 * Microchip mcp3911 ADC.
   - new driver for this integrated analog front end and ADC.
 * Qualcomm SPMI PMIC5 adc driver
   - using the spmi framework, new driver and bindings for this ADC.
     Follow up patch adds some missing channels.
 
 Features
 * ad5758
   - support hard reset using a gpio (if provided).
 * mpu6050
   - Regulator support
 * qcom-spmi-adc5
   - Sanity check the channel numbers provided by DT to make sure the
     driver actually knows about them.
 * sc27xx
   - give raw data for channel 20 as it's used on all known boards for
     the headset which needs a custom converstion function.  If it turns
     out someone builds a board where this isn't true we will deal with it
     when it happens.
   - add ADC scale calibration.
 * tsl2772

Merge tag 'iio-for-4.20a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

1st round of IIO new device support, features and cleanups in the 4.20 cycle.

There is a merge commit in here to pull in regmap support for repeatedly
reading the same register (to read out FIFOs).  Used by the adxl372 driver.
This will find uses elsewhere once we tidy up various drivers that are
effectively doing this and relying on not enabling regcache.

New device support
* Analog devices ADXL372 accelerometer
  - new driver for this accelerometer including fifo and and interrupt support.
    Follow up patches enforce trigger validation, add sampling frequency
    control and filter bandwidth control.  A later series added i2c support
    to the existing SPI support.
* ST lsm6dsx
  - rework and add support fo the LSM6DSO 6 axis mems sensor.
* Linear LTC 1660 DAC
  - new driver supporting the LTC 1660 and LTC 1665 SPI DACs.
* Microchip mcp3911 ADC.
  - new driver for this integrated analog front end and ADC.
* Qualcomm SPMI PMIC5 adc driver
  - using the spmi framework, new driver and bindings for this ADC.
    Follow up patch adds some missing channels.

Features
* ad5758
  - support hard reset using a gpio (if provided).
* mpu6050
  - Regulator support
* qcom-spmi-adc5
  - Sanity check the channel numbers provided by DT to make sure the
    driver actually knows about them.
* sc27xx
  - give raw data for channel 20 as it's used on all known boards for
    the headset which needs a custom converstion function.  If it turns
    out someone builds a board where this isn't true we will deal with it
    when it happens.
  - add ADC scale calibration.
* tsl2772
  - support device tree binding to set the proximity led settings.
  - regulator supprot.
  - binding for apds9930 - trivial addition as register compatible with tsl2772.

Add support for overriding the default driver for a VMBus device
in the same way that it can be done for PCI devices. This patch
adds the /sys/bus/vmbus/devices/.../driver_override file
and the logic for matching.

This is used by driverctl tool to do driver override.

Persistent grants are allocated until a threshold per ring is being

meaning there will be resources kept busy which might no longer be
used.

Instead of freeing only persistent grants until the threshold is
reached add a timestamp and remove all persistent grants not having
been in use for a minute.

Linus Torvalds 899fbc33fd platform-drivers-x86 for v4.19-1
The driver for Silead touchscreen configurations has been renamed
 from silead_dmi to touchscreen_dmi since it starts supporting other
 touchscreens which require some DMI quirks. At the same release cycle
 it gets expanded to cover cases for Chuwi Vi10, ONDA V891W,
 Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets.
 
 Another bunch of changes is related to Mellanox platform code to allow
 user space to communicate with Mellanox for system control and
 monitoring purposes. The driver notifies user on hotplug device signal
 receiving.
 
 ASUS WMI drivers recognize lid flip action on UX360, and correctly
 toggles airplane mode LED. In addition the keyboard backlight toggle
 gets support.
 
 ThinkPad ACPI driver enables support for calculator key (on at least P52).
 It also has been fixed to support three characters model designators,
 which are used for modern laptops. Earlier the battery, marked as BAT1,
 on ThinkPad laptops has not been configured properly, which is fixed.
 On the opposite the multi-battery configurations now probed correctly.
 
 Dell SMBIOS driver starts working on some Dell servers which do not
 support token interface. The regression with backlight detection has
 also been fixed. In order to support dock mode on some laptops,
 Intel virtual button driver has been fixed. The last but not least
 is the fix to Intel HID driver due to changes in Dell systems that
 prevented to use power button.

Linus Torvalds fe6f0ed0da f2fs-for-4.19-rc1
In this round, we've tuned f2fs to improve general performance by serializing
 block allocation and enhancing discard flows like fstrim which avoids user IO
 contention. And we've added fsync_mode=nobarrier which gives an option to user
 where it skips issuing cache_flush commands to underlying flash storage. And
 there are many bug fixes related to fuzzed images, revoked atomic writes, quota
 ops, and minor direct IO.
 
 Enhancement:
  - add fsync_mode=nobarrier which bypasses cache_flush command
  - enhance the discarding flow which avoids user IOs and issues in LBA order
  - readahead some encrypted blocks during GC
  - enable in-memory inode checksum to verify the blocks if F2FS_CHECK_FS is set
  - enhance nat_bits behavior
  - set -o discard by default
  - set REQ_RAHEAD to bio in ->readpages
 
 Bug fixes:

Merge tag 'f2fs-for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've tuned f2fs to improve general performance by
  serializing block allocation and enhancing discard flows like fstrim
  which avoids user IO contention. And we've added fsync_mode=nobarrier
  which gives an option to user where it skips issuing cache_flush
  commands to underlying flash storage. And there are many bug fixes
  related to fuzzed images, revoked atomic writes, quota ops, and minor
  direct IO.

  Enhancements:
   - add fsync_mode=nobarrier which bypasses cache_flush command
   - enhance the discarding flow which avoids user IOs and issues in
     LBA order
   - readahead some encrypted blocks during GC
   - enable in-memory inode checksum to verify the blocks if
     F2FS_CHECK_FS is set
   - enhance nat_bits behavior
   - set -o discard by default
   - set REQ_RAHEAD to bio in ->readpages

  Bug fixes:
   - fix a corner case to corrupt atomic_writes revoking flow
   - revisit i_gc_rwsem to fix race conditions
   - fix some dio behaviors captured by xfstests
   - correct handling errors given by quota-related failures
   - add many sanity check flows to avoid fuzz test failures
   - add more error number propagation to their callers
   - fix several corner cases to continue fault injection w/ shutdown
     loop"

Linus Torvalds d5acba26bf Char/Misc driver patches for 4.19-rc1
Here is the bit set of char/misc drivers for 4.19-rc1
 
 There is a lot here, much more than normal, seems like everyone is
 writing new driver subsystems these days...  Anyway, major things here
 are:
 	- new FSI driver subsystem, yet-another-powerpc low-level
 	  hardware bus
 	- gnss, finally an in-kernel GPS subsystem to try to tame all of
 	  the crazy out-of-tree drivers that have been floating around
 	  for years, combined with some really hacky userspace
 	  implementations.  This is only for GNSS receivers, but you
 	  have to start somewhere, and this is great to see.
 Other than that, there are new slimbus drivers, new coresight drivers,
 new fpga drivers, and loads of DT bindings for all of these and existing
 drivers.
 
 Full details of everything is in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

Linus Torvalds 2475c515d4 Staging/IIO patches for 4.19-rc1
Here are the big staging/iio patches for 4.19-rc1.
 
 Lots of churn here, with tons of cleanups happening in staging drivers,
 a removal of an old crypto driver that no one was using (skein), and the
 addition of some new IIO drivers.  Also added was a "gasket" driver from
 Google that needs loads of work and the erofs filesystem.
 
 Even with adding all of the new drivers and a new filesystem, we are
 only adding about 1000 lines overall to the kernel linecount, which
 shows just how much cleanup happened, and how big the unused crypto
 driver was.
 
 All of these have been in the linux-next tree for a while now with no
 reported issues.
 
 Note, you will have a merge problem with a device tree IIO file and the
 MAINTAINERS file, both resolutions are easy, just take all changed.
 There will be a skein file merge issue as well, but that file got
 deleted so just drop that.

Linus Torvalds 5e2d059b52 powerpc updates for 4.19
Notable changes:
 
  - A fix for a bug in our page table fragment allocator, where a page table page
    could be freed and reallocated for something else while still in use, leading
    to memory corruption etc. The fix reuses pt_mm in struct page (x86 only) for
    a powerpc only refcount.
 
  - Fixes to our pkey support. Several are user-visible changes, but bring us in
    to line with x86 behaviour and/or fix outright bugs. Thanks to Florian Weimer
    for reporting many of these.
 
  - A series to improve the hvc driver & related OPAL console code, which have
    been seen to cause hardlockups at times. The hvc driver changes in particular
    have been in linux-next for ~month.
 
  - Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y.
 
  - Remove Power8 DD1 and Power9 DD1 support, neither chip should be in use
    anywhere other than as a paper weight.
 
  - An optimised memcmp implementation using Power7-or-later VMX instructions
 
  - Support for barrier_nospec on some NXP CPUs.
 
  - Support for flushing the count cache on context switch on some IBM CPUs
    (controlled by firmware), as a Spectre v2 mitigation.
 
  - A series to enhance the information we print on unhandled signals to bring it
    into line with other arches, including showing the offending VMA and dumping
    the instructions around the fault.
