6c3ac11343 powerpc updates for 5.1
Notable changes:
 
  - Enable THREAD_INFO_IN_TASK to move thread_info off the stack.
 
  - A big series from Christoph reworking our DMA code to use more of the generic
    infrastructure, as he said:
    "This series switches the powerpc port to use the generic swiotlb and
     noncoherent dma ops, and to use more generic code for the coherent direct
     mapping, as well as removing a lot of dead code."
 
  - Increase our vmalloc space to 512T with the Hash MMU on modern CPUs, allowing
    us to support machines with larger amounts of total RAM or distance between
    nodes.
 
  - Two series from Christophe, one to optimise TLB miss handlers on 6xx, and
    another to optimise the way STRICT_KERNEL_RWX is implemented on some 32-bit
    CPUs.
 
  - Support for KCOV coverage instrumentation which means we can run syzkaller
    and discover even more bugs in our code.
 
 And as always many clean-ups, reworks and minor fixes etc.

Pull audit updates from Paul Moore:
 "A lucky 13 audit patches for v5.1.

  Despite the rather large diffstat, most of the changes are from two
  bug fix patches that move code from one Kconfig option to another.

  Beyond that bit of churn, the remaining changes are largely cleanups
  and bug-fixes as we slowly march towards container auditing. It isn't
  all boring though, we do have a couple of new things: file
  capabilities v3 support, and expanded support for filtering on
  filesystems to solve problems with remote filesystems.

  All changes pass the audit-testsuite.  Please merge for v5.1"

 - Extend LSM stacking to allow sharing of cred, file, ipc, inode, and
   task blobs. This paves the way for more full-featured LSMs to be
   merged, and is specifically aimed at LandLock and SARA LSMs. This
   work is from Casey and Kees.

 - There's a new LSM from Micah Morton: "SafeSetID gates the setid
   family of syscalls to restrict UID/GID transitions from a given
   UID/GID to only those approved by a system-wide whitelist." This
   feature is currently shipping in ChromeOS.

Merge tag 'for-5.1-part1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
 "This contains usual mix of new features, core changes and fixes; full
  list below. I'm planning second pull request, with a few more fixes
  that arrived recently but too close to merge window, will send it next
  week.

  New features:

   - support zstd compression levels

   - new ioctl to unregister a device from the module (ie. reverse of
     device scan)

   - scrub prints a message to log when it's about to start or finish

  Core changes:

   - qgroups can now skip part of a tree that does not get updated
     during relocation, because this does not affect the quota
     accounting, estimated speedup in run time is about 20%

   - the compression workspace management had to be enhanced due to zstd
     requirements

   - various enospc fixes, when there's high fragmentation the
     over-reservation can cause ENOSPC that might not happen after a
     flush, in such cases try to wait if the situation improves

  Fixes:

   - various ioctls could overwrite previous return value if
     copy_to_user fails, fix this so the original error is reported

   - more reclaim vs GFP_KERNEL fixes

   - other cleanups and refactoring

   - fix a (valid) lockdep warning in a test when device replace is
     destroying worker threads

   - make qgroup async transaction commit more aggressive, this avoids
     some 'quota limit reached' errors if there are not enough data to
     trigger transaction in order to flush

   - fix deadlock between snapshot deletion and quotas when backref
     walking is called from context that already holds the same locks

   - fsync fixes:
      - fix fsync after succession of renames of different files
      - fix fsync after succession of renames and unlink/rmdir"

eacc95eae6 platform/x86: wmi: move struct wmi_device_id to mod_devicetable.h
In preparation for adding WMI support to MODULE_DEVICE_TABLE() move the
definition of struct wmi_device_id to mod_devicetable.h and inline
guid_string in the struct.

Changing guid_string to an inline char array changes the loop conditions
when looping over an array of struct wmi_device_id. Therefore update
wmi_dev_match()'s loop to check for an empty guid_string instead of a
NULL pointer.

0996584b30 PM-runtime: Call pm_runtime_active|suspended_time() from sysfs
Avoid the open-coding of the accounted time acquisition in
runtime_active|suspend_time_show() and make them call
pm_runtime_active|suspended_time() instead.

Note that this change also indirectly avoids holding dev->power.lock
around the do_div() computation and the sprintf() call which is an
additional improvement.

45763bf4bc Char/Misc driver patches for 5.1-rc1
Here is the big char/misc driver patch pull request for 5.1-rc1.
 
 The largest thing by far is the new habanalabs driver for their AI

 probably move to a new directory soon along with other drivers of this
 type.
 
 Other than that, just the usual set of individual driver updates and
 fixes.  There's an "odd" merge in here from the DRM tree that they asked
 me to do as the MEI driver is starting to interact with the i915 driver,
 and it needed some coordination.  All of those patches have been
 properly acked by the relevant subsystem maintainers.
 
 All of these have been in linux-next with no reported issues, most for

221c5eb233 io_uring: add support for IORING_OP_POLL
This is basically a direct port of bfe4037e722e, which implements a
one-shot poll command through aio. Description below is based on that
commit as well. However, instead of adding a POLL command and relying
on io_cancel(2) to remove it, we mimic the epoll(2) interface of
having a command to add a poll notification, IORING_OP_POLL_ADD,
and one to remove it again, IORING_OP_POLL_REMOVE.

To poll for a file descriptor the application should submit an sqe of
type IORING_OP_POLL. It will poll the fd for the events specified in the
poll_events field.

Unlike poll or epoll without EPOLLONESHOT this interface always works in
one shot mode, that is once the sqe is completed, it will have to be
resubmitted.

f76a16adc4 x86/unwind/orc: Fix ORC unwind table alignment
The .orc_unwind section is a packed array of 6-byte structs.  It's
currently aligned to 6 bytes, which is causing warnings in the LLD
linker.

Six isn't a power of two, so it's not a valid alignment value.  The
actual alignment doesn't matter much because it's an array of packed
structs.  An alignment of two is sufficient.  In reality it always gets
aligned to four bytes because it comes immediately after the
4-byte-aligned .orc_unwind_ip section.

This is easier to avoid by using conventional inline functions
as stubs rather than macros. The header already has inline

macros for consistency.

afe6fe7036 ARM: SoC: late updates for linux-5.1
Here are two branches that came relatively late during the linux-5.0
 development cycle and have dependencies on the other branches:
 
 - On the TI OMAP platform, the CPSW Ethernet PHY mode selection driver
   is being replaced, this puts the final pieces in place
 
 - On the DaVinci platform, the interrupt handling code in arch/arm
   gets moved into a regular device driver in drivers/irqchip.
 
 Since they both had some time in linux-next after the 5.0-rc8
 release, I'm sending them along with the other updates.

384d11fa0e ARM: SoC driver updates for 5.1
As usual, the drivers/tee and drivers/reset subsystems get merged
 here, with the expected set of smaller updates and some new hardware
 support. The tee subsystem now supports device drivers to be attached
 to a tee, the first example here is a random number driver with its
 implementation in the secure world.
 
 Three new power domain drivers get added for specific chip families:
  - Broadcom BCM283x chips (used in Raspberry Pi)
  - Qualcomm Snapdragon phone chips
  - Xilinx ZynqMP FPGA SoCs
 
 One new driver is added to talk to the BPMP firmware on NVIDIA
 Tegra210
 
 Existing drivers are extended for new SoC variants from NXP,
 NVIDIA, Amlogic and Qualcomm.

6ad63dec9c ARM: SoC device tree updates for 5.1
This is a smaller update than the past few times, but with just over
 500 non-merge changesets still dwarfes the rest of the SoC tree.
 
 Three new SoC platforms get added, each one a follow-up to an existing
 product, and added here in combination with a reference platform:
 
  - Renesas RZ/A2M (R7S9210) 32-bit Cortex-A9 Real-time imaging processor
    https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rz/rza/rza2m.html
 
  - Renesas RZ/G2E (r8a774c0) 64-bit Cortex-A53 SoC "for
    Rich Graphics Applications".
    https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rz/rzg/rzg2e.html
 
  - NXP i.MX8QuadXPlus 64-bit Cortex-A35 SoC
    https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/i.mx-applications-processors/i.mx-8-processors/i.mx-8x-family-arm-cortex-a35-3d-graphics-4k-video-dsp-error-correcting-code-on-ddr:i.MX8X
 
 These are actual commercial products we now support with an in-kernel
 device tree source file:
 
  - Bosch Guardian is a product made by Bosch Power
    Tools GmbH, based on the Texas Instruments AM335x chip
 
  - Winterland IceBoard is a Texas Instruments AM3874 based
    machine used in telescopes at the south pole and elsewhere, see commit
    d031773169df2 for some pointers:
 
  - Inspur on5263m5 is an x86 server platform with an Aspeed
    ast2500 baseboard management controller. This is for running on
    the BMC.
 
  - Zodiac Digital Tapping Unit, apparently a kind of ethernet
    switch used in airplanes.
 
  - Phicomm K3 is a WiFi router based on Broadcom bcm47094
 
  - Methode Electronics uDPU FTTdp distribution point unit
 
  - X96 Max, a generic TV box based on Amlogic G12a (S905X2)
 
  - NVIDIA Shield TV (Darcy) based on Tegra210
 
 And then there are several new SBC, evaluation, development or modular
 systems that we add:
 
  - Three new Rockchips rk3399 based boards:
     - FriendlyElec NanoPC-T4 and NanoPi M4
     - Radxa ROCK Pi 4
 
  - Five new i.MX6 family SoM modules and boards for industrial
    products:
     - Logic PD i.MX6QD SoM and evaluation baseboad
     - Y Soft IOTA Draco/Hydra/Ursa family boards based on i.MX6DL
     - Phytec phyCORE i.MX6 UltraLite SoM and evaluation module
 
  - MYIR Tech MYD-LPC4357 development based on the NXP lpc4357
    microcontroller
 
  - Chameleon96, an Intel/Altera Cyclone5 based FPGA development
    system in 96boards form factor
 
  - Arm Fixed Virtual Platforms(FVP) Base RevC, a purely
    virtual platform for corresponding to the latest "fast model"
 
  - Another Raspberry Pi variant: Model 3 A+, supported both
    in 32-bit and 64-bit mode.
 
  - Oxalis Evalkit V100 based on NXP Layerscape LS1012a,
    in 96Boards enterprise form factor
 
  - Elgin RV1108 R1 development board based on 32-bit Rockchips RV1108
 
 For already supported boards and SoCs, we often add support for new
 devices after merging the drivers. This time, the largest changes include
 updates for
 
  - STMicroelectronics stm32mp1, which was now formally
    launched last week
 
  - Qualcomm Snapdragon 845, a high-end phone and low-end laptop chip
 
  - Action Semi S700
 
  - TI AM654x, their recently merged 64-bit SoC from the OMAP family
 
  - Various Amlogic Meson SoCs
 
  - Mediatek MT2712
 
  - NVIDIA Tegra186 and Tegra210
 
  - The ancient NXP lpc32xx family
 
  - Samsung s5pv210, used in some older mobile phones
 
 Many other chips see smaller updates and bugfixes beyond that.

 Cleanups continue on the older mach-davinci and mach-pxa platform,
 to get them to be more like the modern ones. For pxa, we
 now remove the Raumfeld platform code as it now works with
 device tree based booting.
 
 i.MX adds a couple new features for the i.MX7ULP SoC
 
 Mediatek gains support for a new SoC: MT7629 is a new wireless

 Aside from those, there are the usual minor cleanups and bugfixes
 across several platforms.

fa29f5ba42 asm-generic changes for v5.1
Only a few small changes this time:
 
 - Michael S. Tsirkin cleans up linux/mman.h
 - Mike Rapoport found a typo
 
 I had originally merged another cleanup series for I/O accessors from
 Hugo Lefeuvre as well, but dropped it after the discussion of the barrier
 semantics and some conflicts. I expect this series to get merged for a
 later release though.

ab7a2375fb virtio: hint if callbacks surprisingly might sleep
A virtio transport is free to implement some of the callbacks in
virtio_config_ops in a matter that they cannot be called from
atomic context (e.g. virtio-ccw, which maps a lot of the callbacks
to channel I/O, which is an inherently asynchronous mechanism).
This can be very surprising for developers using the much more
common virtio-pci transport, just to find out that things break
when used on s390.

The documentation for virtio_config_ops now contains a comment
explaining this, but it makes sense to add a might_sleep() annotation
to various wrapper functions in the virtio core to avoid surprises
later.

Note that annotations are NOT added to two classes of calls:
- direct calls from device drivers (all current callers should be
  fine, however)
- calls which clearly won't be made from atomic context (such as
  those ultimately coming in via the driver core)

e6d6dd6c87 virtio: Introduce virtio_max_dma_size()
This function returns the maximum segment size for a single
dma transaction of a virtio device. The possible limit comes
from the SWIOTLB implementation in the Linux kernel, that
has an upper limit of (currently) 256kb of contiguous
memory it can map. Other DMA-API implementations might also
have limits.

Use the new dma_max_mapping_size() function to determine the
maximum mapping size when DMA-API is in use for virtio.

Pull locking updates from Ingo Molnar:
 "The biggest part of this tree is the new auto-generated atomics API
  wrappers by Mark Rutland.

  The primary motivation was to allow instrumentation without uglifying
  the primary source code.

  The linecount increase comes from adding the auto-generated files to
  the Git space as well:

    include/asm-generic/atomic-instrumented.h     | 1689 ++++++++++++++++--
    include/asm-generic/atomic-long.h             | 1174 ++++++++++---
    include/linux/atomic-fallback.h               | 2295 +++++++++++++++++++++++++
    include/linux/atomic.h                        | 1241 +------------

  I preferred this approach, so that the full call stack of the (already
  complex) locking APIs is still fully visible in 'git grep'.

  But if this is excessive we could certainly hide them.

  There's a separate build-time mechanism to determine whether the
  headers are out of date (they should never be stale if we do our job
  right).

  Anyway, nothing from this should be visible to regular kernel
  developers.

  Other changes:

   - Add support for dynamic keys, which removes a source of false
     positives in the workqueue code, among other things (Bart Van
     Assche)

   - Updates to tools/memory-model (Andrea Parri, Paul E. McKenney)

f4b7e272b5 mm: remove zone_lru_lock() function, access ->lru_lock directly
We have common pattern to access lru_lock from a page pointer:
	zone_lru_lock(page_zone(page))

Which is silly, because it unfolds to this:
	&NODE_DATA(page_to_nid(page))->node_zones[page_zonenum(page)]->zone_pgdat->lru_lock
while we can simply do
	&NODE_DATA(page_to_nid(page))->lru_lock

Remove zone_lru_lock() function, since it's only complicate things.  Use
'page_pgdat(page)->lru_lock' pattern instead.

494eec70f0 mm: page_cache_add_speculative(): refactor out some code duplication
From: John Hubbard <jhubbard@nvidia.com>

This combines the common elements of these routines:

    page_cache_get_speculative()
    page_cache_add_speculative()

This was anticipated by the original author, as shown by the comment in
commit ce0ad7f095258 ("powerpc/mm: Lockless get_user_pages_fast() for
64-bit (v3)"):

    "Same as above, but add instead of inc (could just be merged)"

There is no intention to introduce any behavioral change, but there is a
small risk of that, due to slightly differing ways of expressing the
TINY_RCU and related configurations.

This also removes the VM_BUG_ON(in_interrupt()) that was in
page_cache_add_speculative(), but not in page_cache_get_speculative().
This provides slightly less detection of such bugs, but it given that it
was only there on the "add" path anyway, we can likely do without it
just fine.

And it removes the
VM_BUG_ON_PAGE(PageCompound(page) && page != compound_head(page), page);
that page_cache_add_speculative() had.
