7ddd091341 s390/docs: mention subchannel types
Since the original inception of the s390-drivers document, the
common I/O layer has grown support for more types of subchannels.
Give at least a pointer for the various types.

Pull drm updates from Dave Airlie:
 "This seems to have been a comparatively quieter merge window, I assume
  due to holidays etc. The "biggest" change is AMD header cleanups, which
  merge/remove a bunch of them. The AMD gpu scheduler is now being made generic
  with the etnaviv driver wanting to reuse the code, hopefully other drivers
  can go in the same direction.

  Otherwise it's the usual lots of stuff in i915/amdgpu, not so much stuff
  elsewhere.

3879ae653a The core framework has a handful of patches this time around, mostly due
to the clk rate protection support added by Jerome Brunet. This feature
 will allow consumers to lock in a certain rate on the output of a clk so
 that things like audio playback don't hear pops when the clk frequency
 changes due to shared parent clks changing rates. Currently the clk
 API doesn't guarantee the rate of a clk stays at the rate you request
 after clk_set_rate() is called, so this new API will allow drivers
 to express that requirement. Beyond this, the core got some debugfs
 pretty printing patches and a couple minor non-critical fixes.
 
 Looking outside of the core framework diff we have some new driver
 additions and the removal of a legacy TI clk driver. Both of these hit
 high in the dirstat. Also, the removal of the asm-generic/clkdev.h file
 causes small one-liners in all the architecture Kbuild files. Overall, the
 driver diff seems to be the normal stuff that comes all the time to
 fix little problems here and there and to support new hardware.
 
 Core:
  - Clk rate protection
  - Symbolic clk flags in debugfs output
  - Clk registration enabled clks while doing bookkeeping updates
 
 New Drivers:
  - Spreadtrum SC9860
  - HiSilicon hi3660 stub
  - Qualcomm A53 PLL, SPMI clkdiv, and MSM8916 APCS
  - Amlogic Meson-AXG
  - ASPEED BMC
 
 Removed Drivers:
  - TI OMAP 3xxx legacy clk (non-DT) support
  - asm*/clkdev.h got removed (not really a driver)
 
 Updates:
  - Renesas FDP1-0 module clock on R-Car M3-W
  - Renesas LVDS module clock on R-Car V3M
  - Misc fixes to pr_err() prints
  - Qualcomm MSM8916 audio fixes
  - Qualcomm IPQ8074 rounded out support for more peripherals
  - Qualcomm Alpha PLL variants
  - Divider code was using container_of() on bad pointers
  - Allwinner DE2 clks on H3
  - Amlogic minor data fixes and dropping of CLK_IGNORE_UNUSED
  - Mediatek clk driver compile test support
  - AT91 PMC clk suspend/resume restoration support
  - PLL issues fixed on si5351
  - Broadcom IProc PLL calculation updates
  - DVFS support for Armada mvebu CPU clks
  - Allwinner fixed post-divider support
  - TI clkctrl fixes and support for newer SoCs

  spear, mediatek, freescale, qcom, realview, keystone, omap, kirkwood,
  renesas, hisilicon, and broadcom.

  Files get rearranged on a few platforms, in particular the Marvell
  Armada 7K/8K device tree files are changed in preparation for future
  SoC support, based on more than two of the same chips in one package,
  and some boards get renamed for oxnas for consistency.

  Finally, many existing SoCs gain descriptions for additional on-chip
  devices that we can now support with kernel drivers:

   - Allwinner A83t (drm, ethernet, i2c, ...), H3/H5 (USB-OTG)
   - Amlogic AXG family (clk, pinctrl, pwm, ...), and others (vpu, hdmi)

ab486bc9a5 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk
Pull printk updates from Petr Mladek:

 - Add a console_msg_format command line option:

     The value "default" keeps the old "[time stamp] text\n" format. The
     value "syslog" allows to see the syslog-like "<log
     level>[timestamp] text" format.

     This feature was requested by people doing regression tests, for
     example, 0day robot. They want to have both filtered and full logs
     at hands.

 - Reduce the risk of softlockup:

     Pass the console owner in a busy loop.

     This is a new approach to the old problem. It was first proposed by
     Steven Rostedt on Kernel Summit 2017. It marks a context in which
     the console_lock owner calls console drivers and could not sleep.
     On the other side, printk() callers could detect this state and use
     a busy wait instead of a simple console_trylock(). Finally, the
     console_lock owner checks if there is a busy waiter at the end of
     the special context and eventually passes the console_lock to the
     waiter.

     The hand-off works surprisingly well and helps in many situations.
     Well, there is still a possibility of the softlockup, for example,
     when the flood of messages stops and the last owner still has too
     much to flush.

     There is increasing number of people having problems with
     printk-related softlockups. We might eventually need to get better
     solution. Anyway, this looks like a good start and promising
     direction.

 - Do not allow to schedule in console_unlock() called from printk():

     This reverts an older controversial commit. The reschedule helped
     to avoid softlockups. But it also slowed down the console output.
     This patch is obsoleted by the new console waiter logic described
     above. In fact, the reschedule made the hand-off less effective.

 - Deprecate "%pf" and "%pF" format specifier:

     It was needed on ia64, ppc64 and parisc64 to dereference function
     descriptors and show the real function address. It is done
     transparently by "%ps" and "pS" format specifier now.

     Sergey Senozhatsky found that all the function descriptors were in
     a special elf section and could be easily detected.

 - Remove printk_symbol() API:

     It has been obsoleted by "%pS" format specifier, and this change
     helped to remove few continuous lines and a less intuitive old API.

 - Remove redundant memsets:

     Sergey removed unnecessary memset when processing printk.devkmsg
     command line option.

562f36ed28 Kconfig updates for v4.16
A pretty big batch of Kconfig updates. I have to mention the lexer
 and parser of Kconfig are now built from real .l and .y sources.
 So, flex and bison are the requirement for building the kernel.
 Both of them (unlike gperf) have been stable for a long time. This
 change has been tested several weeks in linux-next, and I did not
 receive any problem report about this.
 
 Summary:
 
 - Add checks for mistakes, like the choice default is not in
   choice, help is doubled
 
 - Document data structure and complex code
 
 - Fix various memory leaks
 
 - Change Makefile to build lexer and parser instead of using
   pre-generated C files
 
 - Drop 'boolean' keyword, which is equivalent to 'bool'
 
 - Use default 'yy' prefix and remove unneeded Make variables
 
 - Fix gettext() check for xconfig
 
 - Announce that oldnoconfig will be finally removed
 
 - Make 'Selected by:' and 'Implied by' readable in help and
   search result
 
 - Hide silentoldconfig from 'make help' to stop confusing people
 
 - Fix misc things and cleanups

5d8515bc23 Staging/IIO patches for 4.16-rc1
Here is the big Staging and IIO driver patches for 4.16-rc1.
 
 There is the normal amount of new IIO drivers added, like all releases.
 
 The networking IPX and the ncpfs filesystem are moved into the staging
 tree, as they are on their way out of the kernel due to lack of use
 anymore.
 
 The visorbus subsystem finall has started moving out of the staging tree
 to the "real" part of the kernel, and the most and fsl-mc codebases are
 almost ready to move out, that will probably happen for 4.17-rc1 if all
 goes well.
 
 Other than that, there is a bunch of license header cleanups in the
 tree, along with the normal amount of coding style churn that we all
 know and love for this codebase.  I also got frustrated at the
 Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting
 huge chunks of it that were never even being used.
 
 Full details of everything is in the shortlog.
 
 All of these patches have been in linux-next for a while with no
 reported issues.

  tree, as they are on their way out of the kernel due to lack of use
  anymore.

  The visorbus subsystem finall has started moving out of the staging
  tree to the "real" part of the kernel, and the most and fsl-mc
  codebases are almost ready to move out, that will probably happen for
  4.17-rc1 if all goes well.

  Other than that, there is a bunch of license header cleanups in the
  tree, along with the normal amount of coding style churn that we all
  know and love for this codebase. I also got frustrated at the
  Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting
  huge chunks of it that were never even being used.

  Full details of everything is in the shortlog.

  All of these patches have been in linux-next for a while with no

d6cb41cc44 mm, hugetlb: remove hugepages_treat_as_movable sysctl
hugepages_treat_as_movable has been introduced by 396faf0303 ("Allow
huge page allocations to use GFP_HIGH_MOVABLE") to allow hugetlb
allocations from ZONE_MOVABLE even when hugetlb pages were not
migrateable.  The purpose of the movable zone was different at the time.
It aimed at reducing memory fragmentation and hugetlb pages being long
lived and large werre not contributing to the fragmentation so it was
acceptable to use the zone back then.

Things have changed though and the primary purpose of the zone became
migratability guarantee.  If we allow non migrateable hugetlb pages to
be in ZONE_MOVABLE memory hotplug might fail to offline the memory.

Remove the knob and only rely on hugepage_migration_supported to allow
movable zones.

Mel said:

: Primarily it was aimed at allowing the hugetlb pool to safely shrink with
: the ability to grow it again.  The use case was for batched jobs, some of
: which needed huge pages and others that did not but didn't want the memory
: useless pinned in the huge pages pool.
:
: I suspect that more users rely on THP than hugetlbfs for flexible use of
: huge pages with fallback options so I think that removing the option
: should be ok.

fcb2b0c577 mm: show total hugetlb memory consumption in /proc/meminfo
Currently we display some hugepage statistics (total, free, etc) in
/proc/meminfo, but only for default hugepage size (e.g.  2Mb).

If hugepages of different sizes are used (like 2Mb and 1Gb on x86-64),
/proc/meminfo output can be confusing, as non-default sized hugepages
are not reflected at all, and there are no signs that they are existing
and consuming system memory.

To solve this problem, let's display the total amount of memory,
consumed by hugetlb pages of all sized (both free and used).  Let's call
it "Hugetlb", and display size in kB to match generic /proc/meminfo
style.

For example, (1024 2Mb pages and 2 1Gb pages are pre-allocated):
  $ cat /proc/meminfo
  MemTotal:        8168984 kB
  MemFree:         3789276 kB
  <...>
  CmaFree:               0 kB
  HugePages_Total:    1024
  HugePages_Free:     1024
  HugePages_Rsvd:        0
  HugePages_Surp:        0
  Hugepagesize:       2048 kB
  Hugetlb:         4194304 kB
  DirectMap4k:       32632 kB
  DirectMap2M:     4161536 kB
  DirectMap1G:     6291456 kB

Also, this patch updates corresponding docs to reflect Hugetlb entry
meaning and difference between Hugetlb and HugePages_Total * Hugepagesize.

3c29548f87 Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull integrity updates from James Morris:
 "This contains a mixture of bug fixes, code cleanup, and new
  functionality. Of note is the integrity cache locking fix, file change
  detection, and support for a new EVM portable and immutable signature
  type.

  The re-introduction of the integrity cache lock (iint) fixes the
  problem of attempting to take the i_rwsem shared a second time, when
  it was previously taken exclusively. Defining atomic flags resolves
  the original iint/i_rwsem circular locking - accessing the file data
  vs. modifying the file metadata. Although it fixes the O_DIRECT
  problem as well, a subsequent patch is needed to remove the explicit
  O_DIRECT prevention.

  For performance reasons, detecting when a file has changed and needs
  to be re-measured, re-appraised, and/or re-audited, was limited to
  after the last writer has closed, and only if the file data has
  changed. Detecting file change is based on i_version. For filesystems
  that do not support i_version, remote filesystems, or userspace
  filesystems, the file was measured, appraised and/or audited once and
  never re-evaluated. Now local filesystems, which do not support
  i_version or are not mounted with the i_version option, assume the
  file has changed and are required to re-evaluate the file. This change
  does not address detecting file change on remote or userspace
  filesystems.

  Unlike file data signatures, which can be included and distributed in
  software packages (eg. rpm, deb), the existing EVM signature, which
  protects the file metadata, could not be included in software
  packages, as it includes file system specific information (eg. i_ino,
  possibly the UUID). This pull request defines a new EVM portable and

9798f5178f The is the bulk of GPIO changes for the v4.16 kernel cycle.
Core changes:
 
 - Disallow open drain and open source flags to be set
   simultaneously. This doesn't make electrical sense, and would
   the hardware actually respond to this setting, the result
   would be short circuit.
 
 - ACPI GPIO has a new core infrastructure for handling quirks.
   The quirks are there to deal with broken ACPI tables centrally
   instead of pushing the work to individual drivers. In the world
   of BIOS writers, the ACPI tables are perfect. Until they find a
   mistake in it. When such a mistake is found, we can patch it
   with a quirk. It should never happen, the problem is that it
   happens. So we accomodate for it.
 
 - Several documentation updates.
 
 - Revert the patch setting up initial direction state from
   reading the device. This was causing bad things for drivers
   that can't read status on all its pins. It is only affecting
   debugfs information quality.
 
 - Label descriptors with the device name if no explicit label is
   passed in.
 
 - Pave the ground for transitioning SPI and regulators to use
   GPIO descriptors by implementing some quirks in the device tree
   GPIO parsing code.
 
 New drivers:
 
 - New driver for the Access PCIe IDIO 24 family.
 
 Other:
 
 - Major refactorings and improvements to the GPIO mockup driver
   used for test and verification.
 
 - Moved the AXP209 driver over to pin control since it gained a
   pin control back-end. These patches will appear (with the same
   hashes) in the pin control pull request as well.
 
 - Convert the onewire GPIO driver w1-gpio to use descriptors.
   This is merged here since the W1 maintainers send very few
   pull requests and he ACKed it.
 
 - Start to clean up driver headers using <linux/gpio.h> to just
   use <linux/gpio/driver.h> as appropriate.

0be600a5ad - DM core fixes to ensure that bio submission follows a depth-first tree
walk; this is critical to allow forward progress without the need to
   use the bioset's BIOSET_NEED_RESCUER.
 
 - Remove DM core's BIOSET_NEED_RESCUER based dm_offload infrastructure.
 
 - DM core cleanups and improvements to make bio-based DM more efficient
   (e.g. reduced memory footprint as well leveraging per-bio-data more).
 
 - Introduce new bio-based mode (DM_TYPE_NVME_BIO_BASED) that leverages
   the more direct IO submission path in the block layer; this mode is
   used by DM multipath and also optimizes targets like DM thin-pool that

Pull device mapper updates from Mike Snitzer:

 - DM core fixes to ensure that bio submission follows a depth-first
   tree walk; this is critical to allow forward progress without the
   need to use the bioset's BIOSET_NEED_RESCUER.

 - Remove DM core's BIOSET_NEED_RESCUER based dm_offload infrastructure.

 - DM core cleanups and improvements to make bio-based DM more efficient
   (e.g. reduced memory footprint as well leveraging per-bio-data more).

 - Introduce new bio-based mode (DM_TYPE_NVME_BIO_BASED) that leverages
   the more direct IO submission path in the block layer; this mode is
   used by DM multipath and also optimizes targets like DM thin-pool
   that stack directly on NVMe data device.

 - DM multipath improvements to factor out legacy SCSI-only (e.g.
   scsi_dh) code paths to allow for more optimized support for NVMe
   multipath.

 - A fix for DM multipath path selectors (service-time and queue-length)
   to select paths in a more balanced way; largely academic but doesn't

3da90b159b f2fs-for-4.16-rc1
In this round, we've followed up to support some generic features such as
 cgroup, block reservation, linking fscrypt_ops, delivering write_hints,
 and some ioctls. And, we could fix some corner cases in terms of power-cut
 recovery and subtle deadlocks.
 
 Enhancement:
  - bitmap operations to handle NAT blocks
  - readahead to improve readdir speed
  - switch to use fscrypt_*
  - apply write hints for direct IO
  - add reserve_root=%u,resuid=%u,resgid=%u to reserve blocks for root/uid/gid
  - modify b_avail and b_free to consider root reserved blocks
  - support cgroup writeback
  - support FIEMAP_FLAG_XATTR for fibmap
  - add F2FS_IOC_PRECACHE_EXTENTS to pre-cache extents
  - add F2FS_IOC_{GET/SET}_PIN_FILE to pin LBAs for data blocks
  - support inode creation time
 
 Bug fix:
  - sysfile-based quota operations
  - memory footprint accounting
  - allow to write data on partial preallocation case
  - fix deadlock case on fallocate
  - fix to handle fill_super errors
  - fix missing inode updates of fsync'ed file
  - recover renamed file which was fsycn'ed before
  - drop inmemory pages in corner error case
  - keep last_disk_size correctly
  - recover missing i_inline flags during roll-forward
 
 Various clean-up patches were added as well.

 "Kernel side changes:

   - Clean up the x86 instruction decoder (Masami Hiramatsu)

   - Add new uprobes optimization for PUSH instructions on x86 (Yonghong
     Song)

   - Add MSR_IA32_THERM_STATUS to the MSR events (Stephane Eranian)

   - Fix misc bugs, update documentation, plus various cleanups (Jiri

  There's a large number of tooling side improvements:

   - Intel-PT/BTS improvements (Adrian Hunter)

   - Numerous 'perf trace' improvements (Arnaldo Carvalho de Melo)

   - Introduce an errno code to string facility (Hendrik Brueckner)

   - Various build system improvements (Jiri Olsa)

   - Add support for CoreSight trace decoding by making the perf tools
     use the external openCSD (Mathieu Poirier, Tor Jeremiassen)

   - Add ARM Statistical Profiling Extensions (SPE) support (Kim
     Phillips)

   - libtraceevent updates (Steven Rostedt)

   - Intel vendor event JSON updates (Andi Kleen)

   - Introduce 'perf report --mmaps' and 'perf report --tasks' to show
     info present in 'perf.data' (Jiri Olsa, Arnaldo Carvalho de Melo)

   - Add infrastructure to record first and last sample time to the
     perf.data file header, so that when processing all samples in a
     'perf record' session, such as when doing build-id processing, or
     when specifically requesting that that info be recorded, use that
     in 'perf report --time', that also got support for percent slices
     in addition to absolute ones.

     I.e. now it is possible to ask for the samples in the 10%-20% time
     slice of a perf.data file (Jin Yao)

   - Allow system wide 'perf stat --per-thread', sorting the result (Jin
     Yao)

Pull timer updates from Thomas Gleixner:
 "The timer departement presents:

   - A rather large rework of the hrtimer infrastructure which
     introduces softirq based hrtimers to replace the spread of
     hrtimer/tasklet combos which force the actual callback execution
     into softirq context. The approach is completely different from the
     initial implementation which you cursed at 10 years ago rightfully.

     The softirq based timers have their own queues and there is no
     nasty indirection and list reshuffling in the hard interrupt
     anymore. This comes with conversion of some of the hrtimer/tasklet
     users, the rest and the final removal of that horrible interface
     will come towards the end of the merge window or go through the
     relevant maintainer trees.

     Note: The top commit merged the last minute bugfix for the 10 years
     old CPU hotplug bug as I wanted to make sure that I fatfinger the
     merge conflict resolution myself.

Linus Torvalds
0bae60fcee There are two major achievements for MMC in this release, which deserves to be
specially highlighted.
 
 First, we have converted the MMC block device from using the legacy blk
 interface into using the modern blkmq interface. Not only do we get all the
 nice effects from using blkmq, but it also means that new fresh nice code
 replaces old rusty code. Great news to everybody that cares about MMC/SD!
 
 It should also be noted that converting to blkmq has not been trivial, mostly
 because of that we have been carrying too much of MMC specific optimizations
 for the I/O request path, rather than striving to move these to the generic blk
 layer. Hopefully we won't be doing that mistake, ever again.
 
 Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro), who both
 have been working on this for quite some time!
 
 Second, on top of the blkmq deployment, we have enabled full support the eMMC
 command queuing feature, introduced in the eMMC v.5.1 spec. This also includes
 an implementation of a host driver library, supporting the corresponding CQHCI
 HW. Ideally, those controllers that supports CQHCI should only need some minor
 adaptations to make this play.
 
 So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan driver
 used on Rockchip RK3399, have enabled support for eMMC command queueing.
 
 Worth to highlight is also that, implementing the eMMC command queuing support
 has been a collaborative effort, as several people from Codeaurora, Rockchip,
 Intel and Linaro have been involved. However, the work has been driven by
 Adrian Hunter (Intel).
 
 In some shadow of the above, here are the rest of the highlights:
 
 MMC core:
  - Don't remove non-removable cards during system suspend
  - Add a slot-gpio helper to check capability of GPIO WP detection
 
 MMC host:
  - sdhci: Cleanups and improvements of some wakeup related code
  - sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy
  - sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT
  - sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400
  - sdhci_f_sdh30: Add ACPI support
  - sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume
  - sdhci-of-esdhc: A few minor fixes
  - mmci: Add support for new STM32 variant
  - renesas_sdhi: enable R-Car D3 (r8a77995) support
  - tmio/renesas_sdhi: Re-structuring, cleanups and modernizations

Pull MMC updates from Ulf Hansson:
 "There are two major achievements for MMC in this release, which
  deserves to be specially highlighted.

  First, we have converted the MMC block device from using the legacy
  blk interface into using the modern blkmq interface. Not only do we
  get all the nice effects from using blkmq, but it also means that new
  fresh nice code replaces old rusty code. Great news to everybody that
  cares about MMC/SD!

  It should also be noted that converting to blkmq has not been trivial,
  mostly because of that we have been carrying too much of MMC specific
  optimizations for the I/O request path, rather than striving to move
  these to the generic blk layer. Hopefully we won't be doing that
  mistake, ever again.

  Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro),
  who both have been working on this for quite some time!

  Second, on top of the blkmq deployment, we have enabled full support
  the eMMC command queuing feature, introduced in the eMMC v.5.1 spec.
  This also includes an implementation of a host driver library,
  supporting the corresponding CQHCI HW. Ideally, those controllers that
  supports CQHCI should only need some minor adaptations to make this
  play.

  So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan
  driver used on Rockchip RK3399, have enabled support for eMMC command
  queueing.

  Worth to highlight is also that, implementing the eMMC command queuing
  support has been a collaborative effort, as several people from
  Codeaurora, Rockchip, Intel and Linaro have been involved. However,
  the work has been driven by Adrian Hunter (Intel).

  In some shadow of the above, here are the rest of the highlights:

  MMC core:
   - Don't remove non-removable cards during system suspend
   - Add a slot-gpio helper to check capability of GPIO WP detection

  MMC host:
   - sdhci: Cleanups and improvements of some wakeup related code
   - sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy
   - sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT
   - sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400
   - sdhci_f_sdh30: Add ACPI support
   - sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume
   - sdhci-of-esdhc: A few minor fixes
   - mmci: Add support for new STM32 variant
   - renesas_sdhi: enable R-Car D3 (r8a77995) support
   - tmio/renesas_sdhi: Re-structuring, cleanups and modernizations"
