c4db01edba Merge tag 'tegra-for-4.15-dt-bindings' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/dt
Pull "dt-bindings: Updates for v4.15-rc1" from Thierry Reding:

This contains the addition of a clock alias which will be used to fix
the implementation of the SOR1 clock.

Also included are the bindings for the Tegra186 BPMP thermal driver, a
prerequisite for both the driver and device tree changes.

Pull "Second Round of Renesas ARM Based SoC DT Updates for v4.15" from Simon Horman:

* r8a77430 (RZ/G1M) SoC
  - Add XHCI support to SoC DT. Boards may enable this as appropriate

* All Renesas ARM based SoCs
  - Add missing clocks for ARM CPU cores

    Geert Uytterhoeven says "This series improves DT hardware descriptions
    for Renesas arm32 SoCs by adding missing clocks properties to the
    device nodes corresponding to ARM CPU cores."

* R-Car Gen 1 and 2, and RZ/G SoCs
  - Use R-Car Fallback compat strings for GPIO

    Simon Horman says "Use newly added R-Car GPIO Gen 1, 2 and 3 fallback
    compat strings in peace of now deprecated non-generation specific R-Car
    GPIO fallback compat string in the DT of Renesas ARM and arm64 based
    SoCs.

    As noted in the changelogs for the r8a777[89] changes, this introduces
    an incompatibility with pre-v4.14 kernels used with new DTBs. There is
    no run-time effect for other SoCs updated by this changeset."

* r7s72100 (RZ/A1H) GR-Peach board
  - Add pin configuration subnode for ETHER pin group.
    This avoids relying on boot-loader configuration of these pins.

  - Enable ostm0 and ostm1 timers

    Jacopo Mondi says these are "to be used as clock source and clockevent
    source. The timers provides greater accuracy than the already enabled
    mtu2 one."

  - Correct leds node name indent

  - Enable MTU2 timer pulse unit

   Jacopo Mondi says "MTU2 multi-function/multi-channel timer/counter is
   not enabled for GR-Peach board. The timer is used as clock event source
   to schedule wake-ups, and without this enabled all sleeps not performed
   through busy waiting hang the board."

* r8a7743 (RZ/G1M) iW-RainboW-G20M-Qseven SoM
  - Add USB function support

* r8a7745 (RZ/G1E) iW-RainboW-G22D development platform
  - Add USB2.0 Host support

* r8a7743 (RZ/G1M) iW-RainboW-G20D-Qseven development platform
  - Rework DT architecture and add DT for camera DB

    Fabrizio Castro says "Some of the serial interfaces are exposed on the
    camera daughter board.  The camera daughter board can be connected to
    the carrier board by means of expansion connectors 1, 2 and 3. The
    carrier board may host an RZ/G1M or an RZ/G1N based SoM.

    While adding support for the serial interfaces on the camera daughter
    board we faced the dilemma of how to properly describe all of the
    possible HW configurations and how to maximize code reuse.

    The best option would be to use device tree overlays, however there is
    still some work to be done on that front before actually using them,
    therefore for the time being we decided to provide .dtsi files to
    describe the carrier board and the camera daughter board, and provide
    .dts files to describe the HW configurations we need to support."

* r8a779[0-4] R-Car Gen2 SoCs
  - Use generic node name for VSP1 nodes

    Geert Uytterhoeven says "This patch series replaces the specific node
    names used for the VSP1 nodes by the preferred generic node names, cfr.
    commit 0e1bfb72b0 ("v4l: vsp1: Use generic node name")."

3e09b155d5 dt-bindings: Add bindings for nvidia,tegra186-bpmp-thermal
In Tegra186, the BPMP (Boot and Power Management Processor) implements
an interface that is used to read system temperatures, including CPU
cluster and GPU temperatures. This binding describes the thermal sensor
that is exposed by BPMP.

4d1dc40185 dt-bindings: clock: tegra: Add sor1_out clock
The sor1_src clock implemented on Tegra210 is modelled the wrong way
around, which causes some issues with HDMI and DP support. This clock
implementation is provided by BPMP on Tegra186, which models this in
a more correct way. Since this introduces incompatibilities between
the two SoC generations which we want to avoid, the Tegra210 will be
fixed in subsequent patches.

This change adds sor1_out as an alias for sor1_src.

162d58c26d ARM: dts: stm32: change pinctrl bindings definition
Initially each pin was declared in "include/dt-bindings/stm32<SOC>-pinfunc.h"
and each definition contained SOC names (ex: STM32F429_PA9_FUNC_USART1_TX).
Since this approach was approved, the number of supported MCU has
increased (STM32F429/STM32F469/STM32f746/STM32H743). To avoid to add a new
file in "include/dt-bindings" each time a new STM32 SOC arrives I propose
a new approach which consist to use a macro to define pin muxing in device
tree. All STM32 will use the common macro to define pinmux. Furthermore, it
will make STM32 maintenance and integration of new SOC easier .

Add the missing definitions for the I (CPU) and G (Image Processing)
clocks, so these clocks can be referred to from device nodes in DT.

Note that these clocks are already fully supported otherwise (DT
bindings, Linux driver, r7s72100.dtsi), they were just omitted from the
header file.

27efed3e83 Merge branch 'core-watchdog-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull watchddog clean-up and fixes from Thomas Gleixner:
 "The watchdog (hard/softlockup detector) code is pretty much broken in
  its current state. The patch series addresses this by removing all
  duct tape and refactoring it into a workable state.

  The reasons why I ask for inclusion that late in the cycle are:

   1) The code causes lockdep splats vs. hotplug locking which get
      reported over and over. Unfortunately there is no easy fix.

   2) The risk of breakage is minimal because it's already broken

   3) As 4.14 is a long term stable kernel, I prefer to have working
      watchdog code in that and the lockdep issues resolved. I wouldn't
      ask you to pull if 4.14 wouldn't be a LTS kernel or if the
      solution would be easy to backport.

   4) The series was around before the merge window opened, but then got
      delayed due to the UP failure caused by the for_each_cpu()
      surprise which we discussed recently.

  Changes vs. V1:

   - Addressed your review points

   - Addressed the warning in the powerpc code which was discovered late

   - Changed two function names which made sense up to a certain point
     in the series. Now they match what they do in the end.

   - Fixed a 'unused variable' warning, which got not detected by the
     intel robot. I triggered it when trying all possible related config
     combinations manually. Randconfig testing seems not random enough.

  The changes have been tested by and reviewed by Don Zickus and tested
  and acked by Micheal Ellerman for powerpc"

34ddaa3e5c powerpc/watchdog: Make use of watchdog_nmi_probe()
The rework of the core hotplug code triggers the WARN_ON in start_wd_cpu()
on powerpc because it is called multiple times for the boot CPU.

The first call is via:

  start_wd_on_cpu+0x80/0x2f0
  watchdog_nmi_reconfigure+0x124/0x170
  softlockup_reconfigure_threads+0x110/0x130
  lockup_detector_init+0xbc/0xe0
  kernel_init_freeable+0x18c/0x37c
  kernel_init+0x2c/0x160
  ret_from_kernel_thread+0x5c/0xbc

And then again via the CPU hotplug registration:

  start_wd_on_cpu+0x80/0x2f0
  cpuhp_invoke_callback+0x194/0x620
  cpuhp_thread_fun+0x7c/0x1b0
  smpboot_thread_fn+0x290/0x2a0
  kthread+0x168/0x1b0
  ret_from_kernel_thread+0x5c/0xbc

This can be avoided by setting up the cpu hotplug state with nocalls and
move the initialization to the watchdog_nmi_probe() function. That
initializes the hotplug callbacks without invoking the callback and the
following core initialization function then configures the watchdog for the
online CPUs (in this case CPU0) via softlockup_reconfigure_threads().

6b9dc4806b watchdog/core, powerpc: Replace watchdog_nmi_reconfigure()
The recent cleanup of the watchdog code split watchdog_nmi_reconfigure()
into two stages. One to stop the NMI and one to restart it after
reconfiguration. That was done by adding a boolean 'run' argument to the
code, which is functionally correct but not necessarily a piece of art.

Replace it by two explicit functions: watchdog_nmi_stop() and
watchdog_nmi_start().

de3ee99b09 mmc: Delete bounce buffer handling
In may, Steven sent a patch deleting the bounce buffer handling
and the CONFIG_MMC_BLOCK_BOUNCE option.

I chose the less invasive path of making it a runtime config
option, and we merged that successfully for kernel v4.12.

The code is however just standing in the way and taking up
space for seemingly no gain on any systems in wide use today.

Pierre says the code was there to improve speed on TI SDHCI
controllers on certain HP laptops and possibly some Ricoh
controllers as well. Early SDHCI controllers lacked the
scatter-gather feature, which made software bounce buffers
a significant speed boost.

We are clearly talking about the list of SDHCI PCI-based
MMC/SD card readers found in the pci_ids[] list in
drivers/mmc/host/sdhci-pci-core.c.

The TI SDHCI derivative is not supported by the upstream
kernel. This leaves the Ricoh.

What we can however notice is that the x86 defconfigs in the
kernel did not enable CONFIG_MMC_BLOCK_BOUNCE option, which
means that any such laptop would have to have a custom
configured kernel to actually take advantage of this
bounce buffer speed-up. It simply seems like there was
a speed optimization for the Ricoh controllers that noone
was using. (I have not checked the distro defconfigs but
I am pretty sure the situation is the same there.)

Bounce buffers increased performance on the OMAP HSMMC
at one point, and was part of the original submission in
commit a45c6cb816 ("[ARM] 5369/1: omap mmc: Add new
   omap hsmmc controller for 2430 and 34xx, v3")

This optimization was removed in
commit 0ccd76d4c2 ("omap_hsmmc: Implement scatter-gather
   emulation")
which found that scatter-gather emulation provided even
better performance.

The same was introduced for SDHCI in
commit 2134a922c6 ("sdhci: scatter-gather (ADMA) support")

I am pretty positively convinced that software
scatter-gather emulation will do for any host controller what
the bounce buffers were doing. Essentially, the bounce buffer
was a reimplementation of software scatter-gather-emulation in
the MMC subsystem, and it should be done away with.

1dd2bfc868 mm/memory_hotplug: change pfn_to_section_nr/section_nr_to_pfn macro to inline function
pfn_to_section_nr() and section_nr_to_pfn() are defined as macro.
pfn_to_section_nr() has no issue even if it is defined as macro.  But
section_nr_to_pfn() has overflow issue if sec is defined as int.

section_nr_to_pfn() just shifts sec by PFN_SECTION_SHIFT.  If sec is
defined as unsigned long, section_nr_to_pfn() returns pfn as 64 bit value.
But if sec is defined as int, section_nr_to_pfn() returns pfn as 32 bit
value.

__remove_section() calculates start_pfn using section_nr_to_pfn() and
scn_nr defined as int.  So if hot-removed memory address is over 16TB,
overflow issue occurs and section_nr_to_pfn() does not calculate correct
pfn.

To make callers use proper arg, the patch changes the macros to inline
functions.

c2315c187f exec: load_script: kill the onstack interp[BINPRM_BUF_SIZE] array
Patch series "exec: binfmt_misc: fix use-after-free, kill
iname[BINPRM_BUF_SIZE]".

It looks like this code was always wrong, then commit 948b701a60
("binfmt_misc: add persistent opened binary handler for containers")
added more problems.

This patch (of 6):

load_script() can simply use i_name instead, it points into bprm->buf[]
and nobody can change this memory until we call prepare_binprm().

The only complication is that we need to also change the signature of
bprm_change_interp() but this change looks good too.

While at it, do whitespace/style cleanups.

NOTE: the real motivation for this change is that people want to
increase BINPRM_BUF_SIZE, we need to change load_misc_binary() too but
this looks more complicated because afaics it is very buggy.

4d4bbd8526 mm, oom_reaper: skip mm structs with mmu notifiers
Andrea has noticed that the oom_reaper doesn't invalidate the range via
mmu notifiers (mmu_notifier_invalidate_range_start/end) and that can
corrupt the memory of the kvm guest for example.

tlb_flush_mmu_tlbonly already invokes mmu notifiers but that is not
sufficient as per Andrea:

 "mmu_notifier_invalidate_range cannot be used in replacement of
  mmu_notifier_invalidate_range_start/end. For KVM
  mmu_notifier_invalidate_range is a noop and rightfully so. A MMU
  notifier implementation has to implement either ->invalidate_range
  method or the invalidate_range_start/end methods, not both. And if you
  implement invalidate_range_start/end like KVM is forced to do, calling
  mmu_notifier_invalidate_range in common code is a noop for KVM.

  For those MMU notifiers that can get away only implementing
  ->invalidate_range, the ->invalidate_range is implicitly called by
  mmu_notifier_invalidate_range_end(). And only those secondary MMUs
  that share the same pagetable with the primary MMU (like AMD iommuv2)
  can get away only implementing ->invalidate_range"

As the callback is allowed to sleep and the implementation is out of
hand of the MM it is safer to simply bail out if there is an mmu
notifier registered.  In order to not fail too early make the
mm_has_notifiers check under the oom_lock and have a little nap before
failing to give the current oom victim some more time to exit.

There's a typo in recent change of VM_MPX definition.  We want it to be
VM_HIGH_ARCH_4, not VM_HIGH_ARCH_BIT_4.

This bug does cause visible regressions.  In arch_vma_name the vmflags
are tested against VM_MPX.  With the incorrect value of VM_MPX, a number
of vmas (such as the stack) test positive and end up being marked as
"[mpx]" in /proc/N/maps instead of their correct names.

This confuses tools like rr which expect to be able to find familiar
vmas.

  Clarify that in the comment.
- fix x64 JIT of bpf_tail_call which was incorrectly loading 8 instead of 4 bytes
- tighten corresponding check in the interpreter to stay consistent

The JIT bug can be triggered after introduction of BPF_F_NUMA_NODE flag
in commit 96eabe7a40 in 4.14. Before that the map_flags would stay zero and
though JIT code is wrong it will check bounds correctly.
Hence two fixes tags. All other JITs don't have this problem.

Pull driver core fixes from Greg KH:
 "Here are a few small fixes for 4.14-rc4.

  The removal of DRIVER_ATTR() was almost completed by 4.14-rc1, but one
  straggler made it in through some other tree (odds are, one of
  mine...) So there's a simple removal of the last user, and then
  finally the macro is removed from the tree.

  There's a fix for old crazy udev instances that insist on reloading a
  module when it is removed from the kernel due to the new uevents for
  bind/unbind. This fixes the reported regression, hopefully some year
  in the future we can drop the workaround, once users update to the
  latest version, but I'm not holding my breath.

  And then there's a build fix for a linker warning, and a buffer
  overflow fix to match the PCI fixes you took through the PCI tree in
  the same area.

  All of these have been in linux-next for a few weeks while I've been
  traveling, sorry for the delay"

28a0bc4120 scsi: sd: Implement blacklist option for WRITE SAME w/ UNMAP
SBC-4 states:

  "A MAXIMUM UNMAP LBA COUNT field set to a non-zero value indicates the
   maximum number of LBAs that may be unmapped by an UNMAP command"

  "A MAXIMUM WRITE SAME LENGTH field set to a non-zero value indicates
   the maximum number of contiguous logical blocks that the device server
   allows to be unmapped or written in a single WRITE SAME command."

Despite the spec being clear on the topic, some devices incorrectly
expect WRITE SAME commands with the UNMAP bit set to be limited to the
value reported in MAXIMUM UNMAP LBA COUNT in the Block Limits VPD.

Implement a blacklist option that can be used to accommodate devices
with this behavior.

Pull timer fixes from Thomas Gleixner:
 "This adds a new timer wheel function which is required for the
  conversion of the timer callback function from the 'unsigned long
  data' argument to 'struct timer_list *timer'. This conversion has two
  benefits:

   1) It makes struct timer_list smaller

   2) Many callers hand in a pointer to the timer or to the structure
      containing the timer, which happens via type casting both at setup
      and in the callback. This change gets rid of the typecasts.

  Once the conversion is complete, which is planned for 4.15, the old
  setup function and the intermediate typecast in the new setup function
  go away along with the data field in struct timer_list.

  Merging this now into mainline allows a smooth queueing of the actual
  conversion in the affected maintainer trees without creating
  dependencies"

bc044e8db7 udp: perform source validation for mcast early demux
The UDP early demux can leverate the rx dst cache even for
multicast unconnected sockets.

In such scenario the ipv4 source address is validated only on
the first packet in the given flow. After that, when we fetch
the dst entry  from the socket rx cache, we stop enforcing
the rp_filter and we even start accepting any kind of martian
addresses.

Disabling the dst cache for unconnected multicast socket will
cause large performace regression, nearly reducing by half the
max ingress tput.

Instead we factor out a route helper to completely validate an
skb source address for multicast packets and we call it from
the UDP early demux for mcast packets landing on unconnected
sockets, after successful fetching the related cached dst entry.

This still gives a measurable, but limited performance
regression:

		rp_filter = 0		rp_filter = 1
edmux disabled:	1182 Kpps		1127 Kpps
edmux before:	2238 Kpps		2238 Kpps
edmux after:	2037 Kpps		2019 Kpps

The above figures are on top of current net tree.
Applying the net-next commit 6e617de84e ("net: avoid a full
fib lookup when rp_filter is disabled.") the delta with
rp_filter == 0 will decrease even more.

Currently no error is emitted, but this infrastructure will

Since early demux can do a route lookup and an ipv4 route
lookup can return an error code this is consistent with the

Pull keys fixes from James Morris:
 "Notable here is a rewrite of big_key crypto by Jason Donenfeld to
  address some issues in the original code.

  From Jason's commit log:
   "This started out as just replacing the use of crypto/rng with
    get_random_bytes_wait, so that we wouldn't use bad randomness at
    boot time. But, upon looking further, it appears that there were
    even deeper underlying cryptographic problems, and that this seems
    to have been committed with very little crypto review. So, I rewrote
    the whole thing, trying to keep to the conventions introduced by the
    previous author, to fix these cryptographic flaws."

  There has been positive review of the new code by Eric Biggers and
  Herbert Xu, and it passes basic testing via the keyutils test suite.
  Eric also manually tested it.

  Generally speaking, we likely need to improve the amount of crypto
  review for kernel crypto users including keys (I'll post a note
  separately to ksummit-discuss)"

8ef9925b02 sched/debug: Add explicit TASK_PARKED printing
Currently TASK_PARKED is masqueraded as TASK_INTERRUPTIBLE, give it
its own print state because it will not in fact get woken by regular
wakeups and is a long-term state.

This requires moving TASK_PARKED into the TASK_REPORT mask, and since
that latter needs to be a contiguous bitmask, we need to shuffle the
bits around a bit.

 "Second -rc update for 4.14.

  Both Mellanox and Intel had a series of -rc fixes that landed this
  week. The Mellanox bunch is spread throughout the stack and not just
  in their driver, where as the Intel bunch was mostly in the hfi1
  driver. And, several of the fixes in the hfi1 driver were more than
  just simple 5 line fixes. As a result, the hfi1 driver fixes has a
  sizable LOC count.

  Everything else is as one would expect in an RC cycle in terms of LOC
  count. One item that might jump out and make you think "That's not an
  rc item" is the fix that corrects a typo. But, that change fixes a
  typo in a user visible API that was just added in this merge window,
  so if we fix it now, we can fix it. If we don't, the typo is in the
  API forever. Another that might not appear to be a fix at first glance
  is the Simplify mlx5_ib_cont_pages patch, but the simplification
  allows them to fix a bug in the existing function whenever the length
  of an SGE exceeded page size. We also had to revert one patch from the
