   - perf report now defaults to --group if the perf.data file has
     grouped events, try it with:

   - Introduce the 'perf stat record/report' workflow:

     Generate perf.data files from 'perf stat', to tap into the
     scripting capabilities perf has instead of defining a 'perf stat'
     specific scripting support to calculate event ratios, etc.

     Simple example:

        $ perf stat record -e cycles usleep 1

         Performance counter stats for 'usleep 1':

               1,134,996      cycles

             0.000670644 seconds time elapsed

        $ perf stat report

         Performance counter stats for '/home/acme/bin/perf stat record -e cycles usleep 1':

               1,134,996      cycles

             0.000670644 seconds time elapsed

        $

     It generates PERF_RECORD_ userspace records to store the details:

        $ perf report -D | grep PERF_RECORD
        0xf0 [0x28]: PERF_RECORD_THREAD_MAP nr: 1 thread: 27637
        0x118 [0x12]: PERF_RECORD_CPU_MAP nr: 1 cpu: 65535
        0x12a [0x40]: PERF_RECORD_STAT_CONFIG
        0x16a [0x30]: PERF_RECORD_STAT
        -1 -1 0x19a [0x40]: PERF_RECORD_MMAP -1/0: [0xffffffff81000000(0x1f000000) @ 0xffffffff81000000]: x [kernel.kallsyms]_text
        0x1da [0x18]: PERF_RECORD_STAT_ROUND
        [acme@ssdandy linux]$

     An effort was made to make perf.data files generated like this to
     not generate cryptic messages when processed by older tools.

     The 'perf script' bits need rebasing, will go up later.

   - Make command line options always available, even when they depend
     on some feature being enabled, warning the user about use of such
     options (Wang Nan)

   - Support hw breakpoint events (mem:0xAddress) in the default output
     mode in 'perf script' (Wang Nan)

   - Fixes and improvements for supporting annotating ARM binaries,
     support ARM call and jump instructions, more work needed to have
     arch specific stuff separated into tools/perf/arch/*/annotate/
     (Russell King)

   - Add initial 'perf config' command, for now just with a --list
     command to the contents of the configuration file in use and a
     basic man page describing its format, commands for doing edits and
     detailed documentation are being reviewed and proof-read.  (Taeung
     Song)

   - Allows BPF scriptlets specify arguments to be fetched using DWARF
     info, using a prologue generated at compile/build time (He Kuang,
     Wang Nan)

   - Allow attaching BPF scriptlets to module symbols (Wang Nan)

   - Allow attaching BPF scriptlets to userspace code using uprobe (Wang
     Nan)

   - BPF programs now can specify 'perf probe' tunables via its section
     name, separating key=val values using semicolons (Wang Nan)

     Testing some of these new BPF features:

        Use case: get callchains when receiving SSL packets, filter then in the
                  kernel, at arbitrary place.

        # cat ssl.bpf.c

        }

   - Use 'perf probe' various options to list functions, see what
     variables can be collected at any given point, experiment first
     collecting without a filter, then filter, use it together with
     'perf trace', 'perf top', with or without callchains, if it
     explodes, please tell us!

   - Introduce a new callchain mode: "folded", that will list per line
     representations of all callchains for a give histogram entry,
     facilitating 'perf report' output processing by other tools, such
     as Brendan Gregg's flamegraph tools (Namhyung Kim)

c6e5f16637 KVM: s390: implement the RI support of guest 
This patch adds runtime instrumentation support for KVM guest. We need to
setup a save area for the runtime instrumentation-controls control block(RICCB)
and implement the necessary interfaces to live migrate the guest settings.

We setup the sie control block in a way, that the runtime
instrumentation instructions of a guest are handled by hardware.

We also add a capability KVM_CAP_S390_RI to make this feature opt-in as
it needs migration support.

a4cdb556ca xen/gntdev: add ioctl for grant copy 
Add IOCTL_GNTDEV_GRANT_COPY to allow applications to copy between user
space buffers and grant references.

This interface is similar to the GNTTABOP_copy hypercall ABI except
the local buffers are provided using a virtual address (instead of a
GFN and offset).  To avoid userspace from having to page align its
buffers the driver will use two or more ops if required.

If the ioctl returns 0, the application must check the status of each
segment with the segments status field.  If the ioctl returns a -ve
error code (EINVAL or EFAULT), the status of individual ops is
undefined.

5c919412fe kvm/x86: Hyper-V synthetic interrupt controller 
SynIC (synthetic interrupt controller) is a lapic extension,
which is controlled via MSRs and maintains for each vCPU
 - 16 synthetic interrupt "lines" (SINT's); each can be configured to
   trigger a specific interrupt vector optionally with auto-EOI
   semantics
 - a message page in the guest memory with 16 256-byte per-SINT message
   slots
 - an event flag page in the guest memory with 16 2048-bit per-SINT
   event flag areas

The host triggers a SINT whenever it delivers a new message to the
corresponding slot or flips an event flag bit in the corresponding area.
The guest informs the host that it can try delivering a message by
explicitly asserting EOI in lapic or writing to End-Of-Message (EOM)
MSR.

The userspace (qemu) triggers interrupts and receives EOM notifications
via irqfd with resampler; for that, a GSI is allocated for each
configured SINT, and irq_routing api is extended to support GSI-SINT
mapping.

Changes v4:
* added activation of SynIC by vcpu KVM_ENABLE_CAP
* added per SynIC active flag
* added deactivation of APICv upon SynIC activation

Changes v3:
* added KVM_CAP_HYPERV_SYNIC and KVM_IRQ_ROUTING_HV_SINT notes into
docs

Changes v2:
* do not use posted interrupts for Hyper-V SynIC AutoEOI vectors
* add Hyper-V SynIC vectors into EOI exit bitmap
* Hyper-V SyniIC SINT msr write logic simplified

b16a5b52eb perf/x86: Add option to disable reading branch flags/cycles 
With LBRv5 reading the extra LBR flags like mispredict, TSX, cycles is
not free anymore, as it has moved to a separate MSR.

For callstack mode we don't need any of this information; so we can
avoid the unnecessary MSR read. Add flags to the perf interface where
perf record can request not collecting this information.

Add branch_sample_type flags for CYCLES and FLAGS. It's a bit unusual
for branch_sample_types to be negative (disable), not positive (enable),
but since the legacy ABI reported the flags we need some form of
explicit disabling to avoid breaking the ABI.

After we have the flags the x86 perf code can keep track if any users
need the flags. If noone needs it the information is not collected.

This cuts down the cost of LBR callstack on Skylake significantly.
Profiling a kernel build with LBR call stack the average run time of
the PMI handler drops by 43%.

8afe97be37 [media] uvcvideo: Enable UVC 1.5 device detection 
UVC 1.5 devices report a bInterfaceProtocol value set to 1 in their
interface descriptors. The uvcvideo driver only matches on
bInterfaceProtocol 0, preventing those devices from being detected.

More changes to the driver are needed for full UVC 1.5 compatibility.
However, at least the UVC 1.5 Microsoft Surface Pro 3 cameras have been
reported to work out of the box with the driver with an updated match
table.

Enable UVC 1.5 support in the match table to support the devices that
can work with the current driver implementation. Devices that can't will
fail, but that's hardly a regression as they're currently not detected
at all anyway.

d647f0b70c [media] include/media: move driver interface headers to a separate dir 
Let's not mix headers used by the core with those headers that
are needed by some driver-specific interface header.

The headers used on drivers were manually moved using:
    mkdir include/media/drv-intf/
    git mv include/media/cx2341x.h include/media/cx25840.h \
	include/media/exynos-fimc.h include/media/msp3400.h \
	include/media/s3c_camif.h include/media/saa7146.h \

	include/media/si476x.h include/media/soc_mediabus.h \
	include/media/tea575x.h include/media/drv-intf/

And the references for those headers were corrected using:

    MAIN_DIR="media/"
    PREV_DIR="media/"
    DIRS="drv-intf/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
		 n=`basename $j`
		git grep -l $n
	done
    done|sort|uniq >files && (
	echo "Handling files..." >&2;
	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
			done;

b44a3d2a85 ARM: SoC driver updates for v4.4 
As we've enabled multiplatform kernels on ARM, and greatly done away with
 the contents under arch/arm/mach-*, there's still need for SoC-related
 drivers to go somewhere.
 
 Many of them go in through other driver trees, but we still have
 drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
 that might be shared between ARM and ARM64 (or just in general makes
 sense to not have under the architecture directory).
 
 This branch contains mostly such code:
 
 - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate
   with power management blocks on these SoCs for use by clock, regulator and
   bus frequency drivers.
 - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs.
 - Drivers for ARM's SCPI (System Control Processor). Not to be confused with
   PSCI (Power State Coordination Interface). SCPI is used to communicate with
   the assistant embedded cores doing power management, and we have yet to see
   how many of them will implement this for their hardware vs abstracting in
   other ways (or not at all like in the past).
 - To make confusion between SCPI and PSCI more likely, this release also
   includes an update of PSCI to interface version 1.0.
 - Rockchip support for power domains.
 - A driver to talk to the firmware on Raspberry Pi.

02f0d3f758 MTD updates for 4.4-rc1: 
Core
 
   * WARN (in some cases) when a struct mtd_info is registered multiple times;
     in the past this was "supported", but it's still error prone for future
     development. There's only one ugly case of this left in the tree (that
     we're aware of) and the owners are aware of the problems there.
 
   * fix potential deadlock in the blkdev removal path
     NOTE: the (potential) deadlock was introduced in a for-stable patch. This
     one is also marked for -stable.
 
   * ioctl(BLKPG) compat_ioctl support; resolves issues with 32-bit user space
     vs. 64-bit kernel space
 
   * Set MTD parent device correctly throughout the tree, so the tree structure
     appears correctly in sysfs; many drivers were missing this (soft)
     requirement
 
   * Move device tree partitions (ofpart) into a dedicated 'partitions' subnode;
     this helps to disambiguate whether a node is a partition or some other
     auxiliary data
 
   * Improve error handling for partitioning failures
 
  NAND
 
   * General: Increase timeout period, for corner-case systems with
     less-than-accurate jiffies
 
   * Fix OF-based autoloading of several NAND drivers when built as modules
 
   * pxa3xx_nand:
     - Rework timing configuration to be more dynamic
     - Refactor PM support
 
   * brcmnand: prepare for NorthStar 2 support (ARM64, 16-bit NAND chips)
 
   * sunxi_nand: refactoring and a few bug fixes
 
   * vf610: new NAND driver
 
   * FSMC: add SW BCH support; support common NAND DT bindings
 
   * lpc32xx_slc: refactor and improve timing calculations logic
 
   * denali: support for rev 5.1
 
  SPI NOR
 
   * Layering improvements
 
   * Added Winbond lock/unlock support
 
   * Added mtd_is_locked() (i.e., ioctl(MEMISLOCKED)) support

0280d1a099 sound updates for 4.4-rc1 
Here is the first batch of updates for sound system on 4.4-rc1.
 Again at this time, the update looks fairly calm; no big changes in
 either ALSA core or ASoC infrastructures, rather all small cleanups,
 in addition to the new stuff as usual.
 
 The biggest changes are about Firewire sound devices.  It gained lots
 of new device support, and MIDI functionality.  Also there are updates
 for a few still working-in-progress stuff (topology API and ASoC
 skylake), too.  But overall, this update should give no big surprise.
 
 Some highlight is below:
 
 Core:
  - A few more Kconfig items for tinification; it's marked as EXPERT,
    so normal user should't be bothered :)
  - Refactoring with a new PCM hw_constraint helper
  - Removal of unused transfer_ack_{begin,end} PCM callbacks
 
 Firewire:
  - Restructuring of code subtree, lots of refactoring
  - Support AMDTP variants
  - New driver for Digidesign 002/003 family
  - Adds support for TASCAM FireOne to ALSA OXFW driver
  - Add MIDI support to TASCAM and Digi00x devices
 
 HD-Audio:
  - Automated modalias generation for codec drivers, finally
  - Improvement on heuristics for setting mixer name
  - A few fixes for longstanding bugs on Creative CA0132 cards
  - Addition of audio rate callback with i915 communication
  - Fix suspend issue on recent Dell XPS
  - Intel Lewisburg controller support
 
 ASoC:
  - Updates to the topology userspace interface
  - Big updates to the Renesas support (rcar)
  - More updates for supporting Intel Sky Lake systems
  - New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10,
    Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825, Rockchip
    S/PDIF, and Atmel class D amplifier
 
 USB-Audio:
  - A fix for newer Roland MIDI devices
  - Quirks and workarounds for Zoom R16/24 device
 
 Misc:
  - A few fixes for some old Cirrus CS46xx PCI sound boards
  - Yet another fixes for some old ESS Maestro3 PCI sound boards

b0f205c2a3 mm: mlock: add mlock flags to enable VM_LOCKONFAULT usage 
The previous patch introduced a flag that specified pages in a VMA should
be placed on the unevictable LRU, but they should not be made present when
the area is created.  This patch adds the ability to set this state via
the new mlock system calls.

We add MLOCK_ONFAULT for mlock2 and MCL_ONFAULT for mlockall.
MLOCK_ONFAULT will set the VM_LOCKONFAULT modifier for VM_LOCKED.
MCL_ONFAULT should be used as a modifier to the two other mlockall flags.
When used with MCL_CURRENT, all current mappings will be marked with
VM_LOCKED | VM_LOCKONFAULT.  When used with MCL_FUTURE, the mm->def_flags
will be marked with VM_LOCKED | VM_LOCKONFAULT.  When used with both
MCL_CURRENT and MCL_FUTURE, all current mappings and mm->def_flags will be
marked with VM_LOCKED | VM_LOCKONFAULT.

Prior to this patch, mlockall() will unconditionally clear the
mm->def_flags any time it is called without MCL_FUTURE.  This behavior is
maintained after adding MCL_ONFAULT.  If a call to mlockall(MCL_FUTURE) is
followed by mlockall(MCL_CURRENT), the mm->def_flags will be cleared and
new VMAs will be unlocked.  This remains true with or without MCL_ONFAULT
in either mlockall() invocation.

munlock() will unconditionally clear both vma flags.  munlockall()
unconditionally clears for VMA flags on all VMAs and in the mm->def_flags
field.

a8ca5d0ecb mm: mlock: add new mlock system call 
With the refactored mlock code, introduce a new system call for mlock.
The new call will allow the user to specify what lock states are being
added.  mlock2 is trivial at the moment, but a follow on patch will add a
new mlock state making it useful.

933425fb00 s390: A bunch of fixes and optimizations for interrupt and time 
handling.
 
 PPC: Mostly bug fixes.
 
 ARM: No big features, but many small fixes and prerequisites including:
 - a number of fixes for the arch-timer
 - introducing proper level-triggered semantics for the arch-timers
 - a series of patches to synchronously halt a guest (prerequisite for
   IRQ forwarding)
 - some tracepoint improvements
 - a tweak for the EL2 panic handlers
 - some more VGIC cleanups getting rid of redundant state
 
 x86: quite a few changes:
 
 - support for VT-d posted interrupts (i.e. PCI devices can inject
 interrupts directly into vCPUs).  This introduces a new component (in
 virt/lib/) that connects VFIO and KVM together.  The same infrastructure
 will be used for ARM interrupt forwarding as well.
 
 - more Hyper-V features, though the main one Hyper-V synthetic interrupt
 controller will have to wait for 4.5.  These will let KVM expose Hyper-V
 devices.
 
 - nested virtualization now supports VPID (same as PCID but for vCPUs)
 which makes it quite a bit faster
 
 - for future hardware that supports NVDIMM, there is support for clflushopt,

Pull KVM updates from Paolo Bonzini:
 "First batch of KVM changes for 4.4.

  s390:
     A bunch of fixes and optimizations for interrupt and time handling.

  PPC:
     Mostly bug fixes.

  ARM:
     No big features, but many small fixes and prerequisites including:

      - a number of fixes for the arch-timer

      - introducing proper level-triggered semantics for the arch-timers

      - a series of patches to synchronously halt a guest (prerequisite
        for IRQ forwarding)

      - some tracepoint improvements

      - a tweak for the EL2 panic handlers

      - some more VGIC cleanups getting rid of redundant state

  x86:
     Quite a few changes:

      - support for VT-d posted interrupts (i.e. PCI devices can inject
        interrupts directly into vCPUs).  This introduces a new
        component (in virt/lib/) that connects VFIO and KVM together.
        The same infrastructure will be used for ARM interrupt
        forwarding as well.

      - more Hyper-V features, though the main one Hyper-V synthetic
        interrupt controller will have to wait for 4.5.  These will let
        KVM expose Hyper-V devices.

      - nested virtualization now supports VPID (same as PCID but for
        vCPUs) which makes it quite a bit faster

      - for future hardware that supports NVDIMM, there is support for
        clflushopt, clwb, pcommit

      - support for "split irqchip", i.e.  LAPIC in kernel +
        IOAPIC/PIC/PIT in userspace, which reduces the attack surface of
        the hypervisor

      - obligatory smattering of SMM fixes

      - on the guest side, stable scheduler clock support was rewritten
        to not require help from the hypervisor"
