401721ecd1 kexec: export the value of phys_base instead of symbol address
Currently in x86_64, the symbol address of phys_base is exported to
vmcoreinfo.  Dave Anderson complained this is really useless for his
Crash implementation.  Because in user-space utility Crash and
Makedumpfile which exported vmcore information is mainly used for, value
of phys_base is needed to covert virtual address of exported kernel
symbol to physical address.  Especially init_level4_pgt, if we want to
access and go over the page table to look up a PA corresponding to VA,
firstly we need calculate

  page_dir = SYMBOL(init_level4_pgt) - __START_KERNEL_map + phys_base;

Now in Crash and Makedumpfile, we have to analyze the vmcore elf program
header to get value of phys_base.  As Dave said, it would be preferable
if it were readily availabl in vmcoreinfo rather than depending upon the
PT_LOAD semantics.

Hence in this patch change to export the value of phys_base instead of
its virtual address.

And people also complained that KERNEL_IMAGE_SIZE exporting is x86_64
only, should be moved into arch dependent function
arch_crash_save_vmcoreinfo.  Do the moving in this patch.

69f5838479 Revert "kdump, vmcoreinfo: report memory sections virtual addresses"
This reverts commit 0549a3c02e ("kdump, vmcoreinfo: report memory
sections virtual addresses").

Commit 0549a3c02e tells the userspace utility makedumpfile the
randomized base address of these memmory sections when mm kaslr is
enabled.  However the following patch "kexec: export the value of
phys_base instead of symbol address" makes makedumpfile not need these
addresses any more.

Besides we should use VMCOREINFO_NUMBER to export the value of the
variable so that we can use the existing number_table mechanism of
Makedumpfile to fetch it.  So revert it now.  If needed we can add it
later.

760c6a9139 coredump: clarify "unsafe core_pattern" warning
I was amused to find "unsafe core_pattern" warning having these lines in
/etc/sysctl.conf:

	fs.suid_dumpable=2
	kernel.core_pattern=/core/core-%e-%p-%E
	kernel.core_uses_pid=0

Turns out kernel is formally right.  Default core_pattern is just "core",
which doesn't qualify for secure path while setting suid.dumpable.

Hint admins about solution, clarify sysctl names, delete unnecessary '\'
characters (string literals are concatenated regardless) and reformat for
easier grepping.

c7be96af89 signals: avoid unnecessary taking of sighand->siglock
When running certain database workload on a high-end system with many
CPUs, it was found that spinlock contention in the sigprocmask syscalls
became a significant portion of the overall CPU cycles as shown below.

  9.30%  9.30%  905387  dataserver  /proc/kcore 0x7fff8163f4d2

               |          system_call_fastpath
               |          |
               |          |--50.63%-- __swapcontext

               |          |          ktskRun

Looking further into the swapcontext function in glibc, it was found that
the function always call sigprocmask() without checking if there are
changes in the signal mask.

A check was added to the __set_current_blocked() function to avoid taking
the sighand->siglock spinlock if there is no change in the signal mask.
This will prevent unneeded spinlock contention when many threads are
trying to call sigprocmask().

With this patch applied, the spinlock contention in sigprocmask() was
gone.

73e64c51af mm, compaction: allow compaction for GFP_NOFS requests
compaction has been disabled for GFP_NOFS and GFP_NOIO requests since
the direct compaction was introduced by commit 56de7263fc ("mm:
compaction: direct compact when a high-order allocation fails").  The
main reason is that the migration of page cache pages might recurse back
to fs/io layer and we could potentially deadlock.  This is overly
conservative because all the anonymous memory is migrateable in the
GFP_NOFS context just fine.  This might be a large portion of the memory
in many/most workkloads.

Remove the GFP_NOFS restriction and make sure that we skip all fs pages
(those with a mapping) while isolating pages to be migrated.  We cannot
consider clean fs pages because they might need a metadata update so
only isolate pages without any mapping for nofs requests.

The effect of this patch will be probably very limited in many/most
workloads because higher order GFP_NOFS requests are quite rare,
although different configurations might lead to very different results.
David Chinner has mentioned a heavy metadata workload with 64kB block
which to quote him:

: Unfortunately, there was an era of cargo cult configuration tweaks in the
: Ceph community that has resulted in a large number of production machines
: with XFS filesystems configured this way.  And a lot of them store large
: numbers of small files and run under significant sustained memory
: pressure.
:
: I slowly working towards getting rid of these high order allocations and
: replacing them with the equivalent number of single page allocations, but
: I haven't got that (complex) change working yet.

We can do the following to simulate that workload:
$ mkfs.xfs -f -n size=64k <dev>
$ mount <dev> /mnt/scratch
$ time ./fs_mark  -D  10000  -S0  -n  100000  -s  0  -L  32 \
        -d  /mnt/scratch/0  -d  /mnt/scratch/1 \
        -d  /mnt/scratch/2  -d  /mnt/scratch/3 \
        -d  /mnt/scratch/4  -d  /mnt/scratch/5 \
        -d  /mnt/scratch/6  -d  /mnt/scratch/7 \
        -d  /mnt/scratch/8  -d  /mnt/scratch/9 \
        -d  /mnt/scratch/10  -d  /mnt/scratch/11 \
        -d  /mnt/scratch/12  -d  /mnt/scratch/13 \
        -d  /mnt/scratch/14  -d  /mnt/scratch/15

and indeed is hammers the system with many high order GFP_NOFS requests as
per a simle tracepoint during the load:
$ echo '!(gfp_flags & 0x80) && (gfp_flags &0x400000)' > $TRACE_MNT/events/kmem/mm_page_alloc/filter
I am getting
5287609 order=0
     37 order=1
1594905 order=2
3048439 order=3
6699207 order=4
  66645 order=5

My testing was done in a kvm guest so performance numbers should be
taken with a grain of salt but there seems to be a difference when the
patch is applied:

[ 3063.815003] XFS: fs_mark(3272) possible memory allocation deadlock size 65624 in kmem_alloc (mode:0x2408240)

This suggests that the patch has helped even though there is not all that
much of anonymous memory as the workload mostly generates fs metadata.  I
assume the success rate would be higher with more anonymous memory which
should be the case in many workloads.

4d1f0fb096 kernel/watchdog: use nmi registers snapshot in hardlockup handler
NMI handler doesn't call set_irq_regs(), it's set only by normal IRQ.
Thus get_irq_regs() returns NULL or stale registers snapshot with IP/SP
pointing to the code interrupted by IRQ which was interrupted by NMI.
NULL isn't a problem: in this case watchdog calls dump_stack() and
prints full stack trace including NMI.  But if we're stuck in IRQ
handler then NMI watchlog will print stack trace without IRQ part at
all.

This patch uses registers snapshot passed into NMI handler as arguments:
these registers point exactly to the instruction interrupted by NMI.

Pull MD updates from Shaohua Li:

 - a raid5 writeback cache feature.

   The goal is to aggregate writes to make full stripe write and reduce
   read-modify-write. It's helpful for workload which does sequential
   write and follows fsync for example. This feature is experimental and
   off by default right now.

 - FAILFAST support.

   This fails IOs to broken raid disks quickly, so can improve latency.
   It's mainly for DASD storage, but some patches help normal raid array
   too.

 - support bad block for raid array with external metadata

 - AVX2 instruction support for raid6 parity calculation

 - normalize MD info output

 - add missing blktrace

 - other bug fixes

a829a8445f SCSI misc on 20161213
This update includes the usual round of major driver updates (ncr5380,
 lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas).  There's also
 an assortment of minor fixes, mostly in error legs or other not very
 user visible stuff.  The major change is the pci_alloc_irq_vectors
 replacement for the old pci_msix_.. calls; this effectively makes IRQ
 mapping generic for the drivers and allows blk_mq to use the
 information.

cdb98c2698 Revert "nvme: add support for the Write Zeroes command"
This reverts commit 6d31e3ba23.

This causes bootup problems for me both on my laptop and my desktop.
What they have in common is that they have NVMe disks with dm-crypt, but
it's not the same controller, so it's not controller-specific.

Jens does not see it on his machine (also NVMe), so it's presumably
something that triggers just on bootup.  Possibly related to dm-crypt
and the fact that I mark my luks volume with "allow-discards" in
/etc/crypttab.

It's 100% repeatable for me, which made it fairly straightforward to
bisect the problem to this commit. Small mercies.

So we don't know what the reason is yet, but the revert is needed to get
things going again.

f4000cd997 arm64 updates for 4.10:
- struct thread_info moved off-stack (also touching

 - cpus_have_cap() reworked to avoid __builtin_constant_p() for static

 - Uprobes support (currently only for native 64-bit tasks)

   switching to a reserved page table
 
 - CPU capacity information passing via DT or sysfs (used by the

 - Support for systems without FP/SIMD (IOW, kernel avoids touching these

9f56eca3ae ata: avoid probing NCQ Prio Support if not explicitly requested
Previously, when the ata device was being initialized we were
probing for NCQ prio support by checking the identify information
and also checking the log page that holds information about ncq prio
support.

This caused an error on an Intel HBA so the code is now updated to
only probe for NCQ prio support when the sysfs variable controlling
NCQ prio support is enabled.

tj: Update formatting, switch to spin_[un]lock_irq() and update
    locking a bit, use REVALIDATE instead of RESET, and return -EIO
    instead of -EINVAL on config failure.

Pull libata updates from Tejun Heo:

 - Adam added opt-in ATA command priority support.

 - There are machines which hide multiple nvme devices behind an ahci
   BAR. Dan Williams proposed a solution to force-switch the mode but
   deemed too hackishd. People are gonna discuss the proper way to
   handle the situation in nvme standard meetings. For now, detect and
   warn about the situation.

 - Low level driver specific changes.

Christoph Hellwig pipes in about the hidden nvme warning:
 "I wish that was the case. We've pretty much agreed that we'll want to
  implement it as a virtual PCIe root bridge, similar to Intels other
  'innovation' VMD that we work around that way.

  But Intel management has apparently decided that they don't want to
  spend more cycles on this now that Lenovo has an optional BIOS that
  doesn't force this broken mode anymore, and no one outside of Intel
  has enough information to implement something like this.

  So for now I guess this warning is it, until Intel reconsideres and
  spends resources on fixing up the damage their Chipset people caused"

ef548c551e dm flakey: introduce "error_writes" feature
Recent dm-flakey fixes, to have reads error out during the "down"
interval, made it so that the previous read behaviour is no longer
available.

It is useful to have reads complete like normal but have writes error
out, so make it possible again with a new "error_writes" feature.

098c30557a Driver core patches for 4.10-rc1
Here's the new driver core patches for 4.10-rc1.
 
 Big thing here is the nice addition of "functional dependencies" to the
 driver core.  The idea has been talked about for a very long time, great
 job to Rafael for stepping up and implementing it. It's been tested for
 longer than the 4.9-rc1 date, we held off on merging it earlier in order
 to feel more comfortable about it.
 
 Other than that, it's just a handful of small other patches, some good
 cleanups to the mess that is the firmware class code, and we have a test
 driver for the deferred probe logic.
 
 All of these have been in linux-next for a while with no reported

Here's the "big" staging/iio pull request for 4.10-rc1.
 
 Not as big as 4.9 was, but still just over a thousand changes.  We
 almost broke even of lines added vs. removed, as the slicoss driver was
 removed (got a "clean" driver for the same hardware through the netdev
 tree), and some iio drivers were also dropped, but I think we ended up
 adding a few thousand lines to the source tree in the end.  Other than
 that it's a lot of minor fixes all over the place, nothing major stands
 out at all.
 
 All of these have been in linux-next for a while.  There will be a merge
 conflict with Al's vfs tree in the lustre code, but the resolution for
 that should be pretty simple, that too has been in linux-next.

Pull power management updates from Rafael Wysocki:
 "Again, cpufreq gets more changes than the other parts this time (one
  new driver, one old driver less, a bunch of enhancements of the
  existing code, new CPU IDs, fixes, cleanups)

  There also are some changes in cpuidle (idle injection rework, a
  couple of new CPU IDs, online/offline rework in intel_idle, fixes and
  cleanups), in the generic power domains framework (mostly related to
  supporting power domains containing CPUs), and in the Operating
  Performance Points (OPP) library (mostly related to supporting devices
  with multiple voltage regulators)

  In addition to that, the system sleep state selection interface is
  modified to make it easier for distributions with unchanged user space
  to support suspend-to-idle as the default system suspend method, some
  issues are fixed in the PM core, the latency tolerance PM QoS
  framework is improved a bit, the Intel RAPL power capping driver is
  cleaned up and there are some fixes and cleanups in the devfreq
  subsystem

   - cpufreq core fix to eliminate races that may lead to using inactive
     policy objects and related cleanups (Rafael Wysocki)

   - cpufreq schedutil governor update to make it use SCHED_FIFO kernel
     threads (instead of regular workqueues) for doing delayed work (to
     reduce the response latency in some cases) and related cleanups
     (Viresh Kumar)

   - New cpufreq sysfs attribute for resetting statistics (Markus Mayer)

36869cb93d Merge branch 'for-4.10/block' of git://git.kernel.dk/linux-block
Pull block layer updates from Jens Axboe:
 "This is the main block pull request this series. Contrary to previous
  release, I've kept the core and driver changes in the same branch. We
  always ended up having dependencies between the two for obvious
  reasons, so makes more sense to keep them together. That said, I'll
  probably try and keep more topical branches going forward, especially
  for cycles that end up being as busy as this one.

  The major parts of this pull request is:

   - Improved support for O_DIRECT on block devices, with a small
     private implementation instead of using the pig that is
     fs/direct-io.c. From Christoph.

   - Request completion tracking in a scalable fashion. This is utilized
     by two components in this pull, the new hybrid polling and the
     writeback queue throttling code.

   - Improved support for polling with O_DIRECT, adding a hybrid mode
     that combines pure polling with an initial sleep. From me.

   - Support for automatic throttling of writeback queues on the block
     side. This uses feedback from the device completion latencies to
     scale the queue on the block side up or down. From me.

   - Support from SMR drives in the block layer and for SD. From Hannes
     and Shaun.

   - Multi-connection support for nbd. From Josef.

   - Cleanup of request and bio flags, so we have a clear split between
     which are bio (or rq) private, and which ones are shared. From
     Christoph.

   - A set of patches from Bart, that improve how we handle queue
     stopping and starting in blk-mq.

   - Support for WRITE_ZEROES from Chaitanya.

   - Lightnvm updates from Javier/Matias.

   - Supoort for FC for the nvme-over-fabrics code. From James Smart.

   - A bunch of fixes from a whole slew of people, too many to name
     here"

* 'for-4.10/block' of git://git.kernel.dk/linux-block: (182 commits)
  blk-stat: fix a few cases of missing batch flushing

edc5f445a6 VFIO updates for v4.10-rc1
- VFIO updates for v4.10 primarily include a new Mediated Device
    interface, which essentially allows software defined devices to be
    exposed to users through VFIO.  The host vendor driver providing
    this virtual device polices, or mediates user access to the device.
    These devices often incorporate portions of real devices, for
    instance the primary initial users of this interface expose vGPUs
    which allow the user to map mediated devices, or mdevs, to a
    portion of a physical GPU.  QEMU composes these mdevs into PCI
    representations using the existing VFIO user API.  This enables
    both Intel KVM-GT support, which is also expected to arrive into
    Linux mainline during the v4.10 merge window, as well as NVIDIA
    vGPU, and also Channel I/O devices (aka CCW devices) for s390
    virtualization support. (Kirti Wankhede, Neo Jia)
 
  - Drop unnecessary uses of pcibios_err_to_errno() (Cao Jin)
 
  - Fixes to VFIO capability chain handling (Eric Auger)
 
  - Error handling fixes for fallout from mdev (Christophe JAILLET)
 
  - Notifiers to expose struct kvm to mdev vendor drivers (Jike Song)
 
  - type1 IOMMU model search fixes (Kirti Wankhede, Neo Jia)

   interface, which essentially allows software defined devices to be
   exposed to users through VFIO. The host vendor driver providing this
   virtual device polices, or mediates user access to the device.

   These devices often incorporate portions of real devices, for
   instance the primary initial users of this interface expose vGPUs
   which allow the user to map mediated devices, or mdevs, to a portion
   of a physical GPU. QEMU composes these mdevs into PCI representations
   using the existing VFIO user API. This enables both Intel KVM-GT
   support, which is also expected to arrive into Linux mainline during
   the v4.10 merge window, as well as NVIDIA vGPU, and also Channel I/O
   devices (aka CCW devices) for s390 virtualization support. (Kirti
   Wankhede, Neo Jia)

 - Drop unnecessary uses of pcibios_err_to_errno() (Cao Jin)

 - Fixes to VFIO capability chain handling (Eric Auger)

 - Error handling fixes for fallout from mdev (Christophe JAILLET)

 - Notifiers to expose struct kvm to mdev vendor drivers (Jike Song)

 - type1 IOMMU model search fixes (Kirti Wankhede, Neo Jia)

b8d2798f32 This is a fairly quiet release. We don't have any patches to the core
framework. The only patch that can even be considered "core" adds another
 clk_get() variant. The rest of the changes are in drivers for various SoCs, and
 we have a few bits for ARM shmobile architecture code (dts and mach) due to the
 dependency we're breaking between shmobile architecture code and its clk
 driver. Those shmobile bits have also been pulled into arm-soc tree. Here's the
 summary:
 
 Core:
 
  - Support for devm_get_clk_from_child() used with DT bindings that have
    subnodes with the 'clocks' property
 
 New Drivers:
 
  - Allwinner A64 (sun50i)
  - i.MX imx6ull
  - Socionext's UniPhier SoC CPUs
  - Mediatek MT2701 SoCs

edc57ea92c remoteproc updates for v4.10
Introduces remoteproc "subdevice" support, which allows remoteproc
 driver to associate devices to the "running" state of the remoteproc,
 allowing devices to be probed and removed as the remote processor is
 booted, shut down or recovering from a crash.
 
 Handling of virtio device resources was improved, vring memory is now
 allocated as part of other memory allocation. This ensures that all
 vrings for all virtio devices are allocated before we boot the remote
 processor.
 
 The debugfs mechanism for starting and stopping remoteproc instances was
 replaced with a sysfs interface, also providing a mechanism for
 specifying firmware to use by the instance. This allows user space to
 load and boot use case specific firmware on remote processors.
 
 New drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as
 removal of the unused StE modem loader.
 
 Finally support for crash recovery in the Qualcomm Wirelss subsystem

Merge tag 'rproc-v4.10' of git://github.com/andersson/remoteproc

Pull remoteproc updates from Bjorn Andersson:

 - introduce remoteproc "subdevice" support, which allows remoteproc
   driver to associate devices to the "running" state of the remoteproc,
   allowing devices to be probed and removed as the remote processor is
   booted, shut down or recovering from a crash.

 - handling of virtio device resources was improved, vring memory is now
   allocated as part of other memory allocation. This ensures that all
   vrings for all virtio devices are allocated before we boot the remote
   processor.

 - the debugfs mechanism for starting and stopping remoteproc instances
   was replaced with a sysfs interface, also providing a mechanism for
   specifying firmware to use by the instance. This allows user space to
   load and boot use case specific firmware on remote processors.

 - new drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as
   removal of the unused StE modem loader.

 - finally support for crash recovery in the Qualcomm Wirelss subsystem
   (used for WiFi/BT/FM on a number of platforms) and a number of bug
   fixes and cleanups

5233c331cf It's been an busy period for mmc. Quite some changes in the mmc core, two new
mmc host drivers, some existing drivers being extended to support new IP
 versions and lots of other updates.
 
 MMC core:
  - Delete eMMC packed command support
  - Introduce mmc_abort_tuning() to enable eMMC tuning to fail gracefully
  - Introduce mmc_can_retune() to see if a host can be retuned
  - Re-work and improve the sequence when sending a CMD6 for mmc
  - Enable CDM13 polling when switching to HS and HS DDR mode for mmc
  - Relax checking for CMD6 errors after switch to HS200
  - Re-factoring the code dealing with the mmc block queue
  - Recognize whether the eMMC card supports CMDQ
  - Fix 4K native sector check
  - Don't power off the card when starting the host
  - Increase MMC_IOC_MAX_BYTES to support bigger firmware binaries
  - Improve error handling and drop meaningless BUG_ONs()
  - Lots of clean-ups and changes to improve the quality of the code
 
 MMC host:
  - sdhci: Fix tuning sequence and clean-up the related code
  - sdhci: Add support to via DT override broken SDHCI cap register bits
  - sdhci-cadence: Add new driver for Cadence SD4HC SDHCI variant
  - sdhci-msm: Update clock management
  - sdhci-msm: Add support for eMMC HS400 mode
  - sdhci-msm: Deploy runtime/system PM support
  - sdhci-iproc: Extend driver support to newer IP versions
  - sdhci-pci: Add support for Intel GLK
  - sdhci-pci: Add support for Intel NI byt sdio
  - sdhci-acpi: Add support for 80860F14 UID 2 SDIO bus
  - sdhci: Lots of various small improvements and clean-ups
  - tmio: Add support for tuning
  - sh_mobile_sdhi: Add support for tuning
  - sh_mobile_sdhi: Extend driver to support SDHI IP on R7S72100 SoC
  - sh_mobile_sdhi: remove support for sh7372
  - davinci: Use mmc_of_parse() to enable generic mmc DT bindings
  - meson: Add new driver to support GX platforms
  - dw_mmc: Deploy generic runtime/system PM support
  - dw_mmc: Lots of various small improvements
 
 As a part of the mmc changes this time, I have also pulled in an immutable
 branch/tag (soc-device-match-tag1) hosted by Geert Uytterhoeven, to share the
 implementation of the new soc_device_match() interface. This is needed by the
 below mmc related changes:
  - mmc: sdhci-of-esdhc: Get correct IP version for T4240-R1.0-R2.0
  - soc: fsl: add GUTS driver for QorIQ platforms
