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.

28bc6fb959 SCSI misc on 20180131
This is mostly updates of the usual driver suspects: arcmsr,
 scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas,
 hisi_sas.  We also have a rework of the libsas hotplug handling to
 make it more robust, a slew of 32 bit time conversions and fixes, and
 a host of the usual minor updates and style changes.  The biggest
 potential for regressions is the libsas hotplug changes, but so far
 they seem stable under testing.

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
   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
   hurt.
 
 - Numerous DM raid target fixes and improvements.
 
 - Add a new DM "unstriped" target that enables Intel to workaround
   firmware limitations in some NVMe drives that are striped internally
   (this target also works when stacked above the DM "striped" target).
 
 - Various Documentation fixes and improvements.
 
 - Misc. cleanups and fixes across various DM infrastructure and targets
   (e.g. bufio, flakey, log-writes, snapshot).

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.

Pull arm64 updates from Catalin Marinas:
 "The main theme of this pull request is security covering variants 2
  and 3 for arm64. I expect to send additional patches next week
  covering an improved firmware interface (requires firmware changes)
  for variant 2 and way for KPTI to be disabled on unaffected CPUs
  (Cavium's ThunderX doesn't work properly with KPTI enabled because of
  a hardware erratum).

  Summary:

   - Security mitigations:
      - variant 2: invalidate the branch predictor with a call to
        secure firmware
      - variant 3: implement KPTI for arm64

   - 52-bit physical address support for arm64 (ARMv8.2)

   - arm64 support for RAS (firmware first only) and SDEI (software

Pull perf updates from Ingo Molnar:
 "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
     Olsa)

  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)

     E.g.:

      [root@jouet ~]# perf stat --per-thread --metrics IPC
      ^C

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.

   - The overhaul of the STM32 clocksource/clockevents driver

dc38787a58 regulator: Changes for v4.16
This is a quiet release in terms of code volume but a fairly big one in
 terms of framework changes - we've got one long awaited feature in the
 form of runtime configuration of suspend and the start of coupled
 regulator support too:
 
  - Support for modifying the voltage and enable configuration devices
    will have in suspend, contributed by Chunyan Zhang.
  - Support for the Spreadtrum SC2731, contributed by Erick Chen.
  - The start of changes to support coupled regulators from Maciej
    Purski, the rest of the series should arrive for v4.17.

8e3264710c spi: Updates for v4.16
Quite a quiet release for SPI, there are no changes at all to the core
 and not that many changes to drivers.  Highlights of those driver
 changes include:
 
  - SH MSIOF support for GPIO chip selects contributed by Geert
    Uytterhoeven.
  - Full duplex support for a3700 contributed by Maxime Chevallier.
  - Support for DMA transfers on Atmel devices that require a bounce
    buffer contributed by Radu Pirea.

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 power management updates from Rafael Wysocki:
 "This includes some infrastructure changes in the PM core, mostly
  related to integration between runtime PM and system-wide suspend and
  hibernation, plus some driver changes depending on them and fixes for
  issues in that area which have become quite apparent recently.

  Also included are changes making more x86-based systems use the Low
  Power Sleep S0 _DSM interface by default, which turned out to be
  necessary to handle power button wakeups from suspend-to-idle on
  Surface Pro3.

  On the cpufreq front we have fixes and cleanups in the core, some new
  hardware support, driver updates and the removal of some unused code
  from the CPU cooling thermal driver.

  Apart from this, the Operating Performance Points (OPP) framework is
  prepared to be used with power domains in the future and there is a
  usual bunch of assorted fixes and cleanups.

  Specifics:

   - Define a PM driver flag allowing drivers to request that their
     devices be left in suspend after system-wide transitions to the
     working state if possible and add support for it to the PCI bus
     type and the ACPI PM domain (Rafael Wysocki).

   - Add support for system-wide suspend and resume to the RAPL power
     capping driver and drop a redundant semicolon from it (Zhen Han,
     Luis de Bethencourt).

   - Make SPI domain validation (in the SCSI SPI transport driver) and
     system-wide suspend mutually exclusive as they rely on the same
     underlying mechanism and cannot be carried out at the same time
     (Bart Van Assche).

   - Fix the computation of the amount of memory to preallocate in the

1c1f395b28 sound updates for 4.16-rc1
The major changes in the core API side in this cycle are the still
 on-going ASoC componentization works.  Other than that, only few small
 changes such as 20bit PCM format support are found.
 
 Meanwhile the rest majority of changes are for ASoC drivers:
 - Large cleanups of some of the TI CODEC drivers
 - Continued work on Intel ASoC stuff for new quirks, ACPI GPIO
   handling, Kconfigs and lots of cleanups
 - Refactoring of the Freescale SSI driver, as preliminary work for the
   upcoming changes
 - Work on ST DFSDM driver, including the required IIO patches
 - New drivers for Allwinner A83T, Maxim MAX89373, SocioNext UiniPhier
   EVEA Tempo Semiconductor TSCS42xx and TI PCM816x, TAS5722 and TAS6424
   devices
 - Removal of dead codes for SN95031 and board drivers
 
 Last but not least, a few HD-audio and USB-audio quirks are included
 as usual, too.

regulator: added support for suspend states
Some systems need to set regulators to specific states when they enter
low power modes, especially around CPUs. There are many of these modes
depending on the particular runtime state.

Currently the regulator consumers are not granted permission to change
suspend state of regulator devices, the constraints are configured at
startup.  In order to allow changes in a vlotage range, we need to add
new properties for voltage range and a flag to give permission to
change the suspend voltage and suspend on/off in suspend mode.

3214d01f13 KVM: PPC: Book3S: Provide information about hardware/firmware CVE workarounds
This adds a new ioctl, KVM_PPC_GET_CPU_CHAR, that gives userspace
information about the underlying machine's level of vulnerability
to the recently announced vulnerabilities CVE-2017-5715,
CVE-2017-5753 and CVE-2017-5754, and whether the machine provides
instructions to assist software to work around the vulnerabilities.

The ioctl returns two u64 words describing characteristics of the
CPU and required software behaviour respectively, plus two mask
words which indicate which bits have been filled in by the kernel,
for extensibility.  The bit definitions are the same as for the
new H_GET_CPU_CHARACTERISTICS hypercall.

There is also a new capability, KVM_CAP_PPC_GET_CPU_CHAR, which
indicates whether the new ioctl is available.
