Merge patch series "Fix dt-validate issues on qemu dtbdumps due to dt-bindings" 
Conor Dooley <mail@conchuod.ie> says:

From: Conor Dooley <conor.dooley@microchip.com>

The device trees produced automatically for the virt and spike machines
fail dt-validate on several grounds. Some of these need to be fixed in
the linux kernel's dt-bindings, but others are caused by bugs in QEMU.

Patches been sent that fix the QEMU issues [0], but a couple of them
need to be fixed in the kernel's dt-bindings. The first patches add
compatibles for "riscv,{clint,plic}0" which are present in drivers and
the auto generated QEMU dtbs.

Thanks to Rob Herring for reporting these issues [1],
Conor.

To reproduce the errors:
./build/qemu-system-riscv64 -nographic -machine virt,dumpdtb=qemu.dtb
dt-validate -p /path/to/linux/kernel/Documentation/devicetree/bindings/processed-schema.json qemu.dtb
(The processed schema needs to be generated first)

0 - https://lore.kernel.org/linux-riscv/20220810184612.157317-1-mail@conchuod.ie/
1 - https://lore.kernel.org/linux-riscv/20220803170552.GA2250266-robh@kernel.org/

* fix-dt-validate:
  dt-bindings: riscv: add new riscv,isa strings for emulators
  dt-bindings: interrupt-controller: sifive,plic: add legacy riscv compatible
  dt-bindings: timer: sifive,clint: add legacy riscv compatible

dt-bindings: riscv: add new riscv,isa strings for emulators 
The QEMU virt and spike machines currently export a riscv,isa string of
"rv64imafdcsuh",

While the RISC-V foundation has been ratifying a bunch of extenstions
etc, the kernel has remained relatively static with what hardware is
supported - but the same is not true of QEMU. Using the virt machine
and running dt-validate on the dumped dtb fails, partly due to the
unexpected isa string.

Rather than enumerate the many many possbilities, change the pattern
to a regex, with the following assumptions:
- ima are required
- the single letter order is fixed & we don't care about things that
  can't even do "ima"
- the standard multi letter extensions are all in a "_z<foo>" format
  where the first letter of <foo> is a valid single letter extension
- _s & _h are used for supervisor and hyper visor extensions
- convention says that after the first two chars, a standard multi
  letter extension name could be an english word (ifencei anyone?) so
  it's not worth restricting the charset
- as the above is just convention, don't apply any charset restrictions
  to reduce future churn
- vendor ISA extensions begind with _x and have no charset restrictions
- we don't care about an e extension from an OS pov
- that attempting to validate the contents of the multiletter extensions
  with dt-validate beyond the formatting is a futile, massively verbose
  or unwieldy exercise at best

The following limitations also apply:
- multi letter extension ordering is not enforced. dt-schema does not
  appear to allow for named match groups, so the resulting regex would
  be even more of a headache
- ditto for the numbered extensions

Finally, add me as a maintainer of the binding so that when it breaks
in the future, I can be held responsible!

dt-bindings: interrupt-controller: sifive,plic: add legacy riscv compatible 
While "real" hardware might not use the compatible string "riscv,plic0"
it is present in the driver & QEMU uses it for automatically generated
virt machine dtbs. To avoid dt-validate problems with QEMU produced
dtbs, such as the following, add it to the binding.

riscv-virt.dtb: plic@c000000: compatible: 'oneOf' conditional failed, one must be fixed:
        'sifive,plic-1.0.0' is not one of ['sifive,fu540-c000-plic', 'starfive,jh7100-plic', 'canaan,k210-plic']
        'sifive,plic-1.0.0' is not one of ['allwinner,sun20i-d1-plic']
        'sifive,plic-1.0.0' was expected
        'thead,c900-plic' was expected
riscv-virt.dtb: plic@c000000: '#address-cells' is a required property

d3cf405133 VFIO updates for v6.1-rc1 
- Prune private items from vfio_pci_core.h to a new internal header,
    fix missed function rename, and refactor vfio-pci interrupt defines.
    (Jason Gunthorpe)
 
  - Create consistent naming and handling of ioctls with a function per
    ioctl for vfio-pci and vfio group handling, use proper type args
    where available. (Jason Gunthorpe)
 
  - Implement a set of low power device feature ioctls allowing userspace
    to make use of power states such as D3cold where supported.
    (Abhishek Sahu)
 
  - Remove device counter on vfio groups, which had restricted the page
    pinning interface to singleton groups to account for limitations in
    the type1 IOMMU backend.  Document usage as limited to emulated IOMMU
    devices, ie. traditional mdev devices where this restriction is
    consistent.  (Jason Gunthorpe)
 
  - Correct function prefix in hisi_acc driver incurred during previous
    refactoring. (Shameer Kolothum)
 
  - Correct typo and remove redundant warning triggers in vfio-fsl driver.
    (Christophe JAILLET)
 
  - Introduce device level DMA dirty tracking uAPI and implementation in
    the mlx5 variant driver (Yishai Hadas & Joao Martins)
 
  - Move much of the vfio_device life cycle management into vfio core,
    simplifying and avoiding duplication across drivers.  This also
    facilitates adding a struct device to vfio_device which begins the
    introduction of device rather than group level user support and fills
    a gap allowing userspace identify devices as vfio capable without
    implicit knowledge of the driver. (Kevin Tian & Yi Liu)
 
  - Split vfio container handling to a separate file, creating a more
    well defined API between the core and container code, masking IOMMU
    backend implementation from the core, allowing for an easier future
    transition to an iommufd based implementation of the same.
    (Jason Gunthorpe)
 
  - Attempt to resolve race accessing the iommu_group for a device
    between vfio releasing DMA ownership and removal of the device from
    the IOMMU driver.  Follow-up with support to allow vfio_group to
    exist with NULL iommu_group pointer to support existing userspace
    use cases of holding the group file open.  (Jason Gunthorpe)
 
  - Fix error code and hi/lo register manipulation issues in the hisi_acc
    variant driver, along with various code cleanups. (Longfang Liu)
 
  - Fix a prior regression in GVT-g group teardown, resulting in
    unreleased resources. (Jason Gunthorpe)
 
  - A significant cleanup and simplification of the mdev interface,
    consolidating much of the open coded per driver sysfs interface
    support into the mdev core. (Christoph Hellwig)
 
  - Simplification of tracking and locking around vfio_groups that
    fall out from previous refactoring. (Jason Gunthorpe)
 
  - Replace trivial open coded f_ops tests with new helper.

Merge tag 'vfio-v6.1-rc1' of https://github.com/awilliam/linux-vfio

Pull VFIO updates from Alex Williamson:

 - Prune private items from vfio_pci_core.h to a new internal header,
   fix missed function rename, and refactor vfio-pci interrupt defines
   (Jason Gunthorpe)

 - Create consistent naming and handling of ioctls with a function per
   ioctl for vfio-pci and vfio group handling, use proper type args
   where available (Jason Gunthorpe)

 - Implement a set of low power device feature ioctls allowing userspace
   to make use of power states such as D3cold where supported (Abhishek
   Sahu)

 - Remove device counter on vfio groups, which had restricted the page
   pinning interface to singleton groups to account for limitations in
   the type1 IOMMU backend. Document usage as limited to emulated IOMMU
   devices, ie. traditional mdev devices where this restriction is
   consistent (Jason Gunthorpe)

 - Correct function prefix in hisi_acc driver incurred during previous
   refactoring (Shameer Kolothum)

 - Correct typo and remove redundant warning triggers in vfio-fsl driver
   (Christophe JAILLET)

 - Introduce device level DMA dirty tracking uAPI and implementation in
   the mlx5 variant driver (Yishai Hadas & Joao Martins)

 - Move much of the vfio_device life cycle management into vfio core,
   simplifying and avoiding duplication across drivers. This also
   facilitates adding a struct device to vfio_device which begins the
   introduction of device rather than group level user support and fills
   a gap allowing userspace identify devices as vfio capable without
   implicit knowledge of the driver (Kevin Tian & Yi Liu)

 - Split vfio container handling to a separate file, creating a more
   well defined API between the core and container code, masking IOMMU
   backend implementation from the core, allowing for an easier future
   transition to an iommufd based implementation of the same (Jason
   Gunthorpe)

 - Attempt to resolve race accessing the iommu_group for a device
   between vfio releasing DMA ownership and removal of the device from
   the IOMMU driver. Follow-up with support to allow vfio_group to exist
   with NULL iommu_group pointer to support existing userspace use cases
   of holding the group file open (Jason Gunthorpe)

 - Fix error code and hi/lo register manipulation issues in the hisi_acc
   variant driver, along with various code cleanups (Longfang Liu)

 - Fix a prior regression in GVT-g group teardown, resulting in
   unreleased resources (Jason Gunthorpe)

 - A significant cleanup and simplification of the mdev interface,
   consolidating much of the open coded per driver sysfs interface
   support into the mdev core (Christoph Hellwig)

 - Simplification of tracking and locking around vfio_groups that fall
   out from previous refactoring (Jason Gunthorpe)

 - Replace trivial open coded f_ops tests with new helper (Alex
   Williamson)

doc: RISC-V: Document that misaligned accesses are supported 
The RISC-V ISA manual used to mandate that misaligned accesses were
supported in user mode, but that requirement was removed in 2018 via
riscv-isa-manual commit 61cadb9 ("Provide new description of misaligned
load/store behavior compatible with privileged architecture.").  Since
the Linux uABI was already frozen at that point it's just been demoted
to part of the uABI, but that was never written down.

a251c17aa5 treewide: use get_random_u32() when possible 
The prandom_u32() function has been a deprecated inline wrapper around
get_random_u32() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. The same also applies to get_random_int(), which is
just a wrapper around get_random_u32(). This was done as a basic find
and replace.

 - "perf lock" improvements:
 
   - Add -E/--entries option to limit the number of entries to display, say to ask for
     just the top 5 contended locks.
 
   - Add -q/--quiet option to suppress header and debug messages.
 
   - Add a 'perf test' kernel lock contention entry to test 'perf lock'.
 
 - "perf lock contention" improvements:
 
   - Ask BPF's bpf_get_stackid() to skip some callchain entries.
 
     The ones closer to the tooling are bpf related and not that interesting, the
     ones calling the locking function are the ones we're interested in, example
     of a full, unskipped callstack:
 
   - Allow changing the callstack depth and number of entries to skip.

   perf annotate: Toggle full address <-> offset display
 
 - Add 'f' hotkey to the 'perf annotate' TUI interface when in 'disassembler output'
   mode ('o' hotkey) to toggle showing full virtual address or just the offset.
 
 - Cache DSO build-ids when synthesizing PERF_RECORD_MMAP records for pre-existing threads,

   broadwellx, cascadelakex, haswell, haswellx, icelake, icelakex, ivybridge,
   ivytown, jaketown, sandybridge, sapphirerapids, skylake, skylakex, and
   tigerlake processors.
 
 - Update vendor JSON event files for the ARM Neoverse V1 and E1 platforms.
 
 - Add a 'perf test' entry for 'perf mem' where a struct has false sharing and
   this gets detected in the 'perf mem' output, tested with Intel, AMD and ARM64
   systems.
 
 - Add a 'perf test' entry to test the resolution of java symbols, where an
   output like this is expected:
 
      8.18%  jshell    jitted-50116-29.so    [.] Interpreter
      0.75%  Thread-1  jitted-83602-1670.so  [.] jdk.internal.jimage.BasicImageReader.getString(int)
 
 - Add tests for the ARM64 CoreSight hardware tracing feature, with specially
   crafted pureloop, memcpy, thread loop and unroll tread that then gets
   traced and the output compared with expected output.
 
   Documentation explaining it is also included.
 
 - Add per thread Intel PT 'perf test' entry to check that PERF_RECORD_TEXT_POKE events
   are recorded per CPU, resulting in a mixture of per thread and per CPU events and mmaps,
   verify that this gets all recorded correctly.
 
 - Introduce pthread mutex wrappers to allow for building with clang's
   -Wthread-safety, i.e. using the "guarded_by" "pt_guarded_by" "lockable",
   "exclusive_lock_function", "exclusive_trylock_function",
   "exclusive_locks_required", and "no_thread_safety_analysis" compiler function
   attributes.
 
 - Fix empty version number when building outside of a git repo.
 
 - Improve feature detection display when multiple versions of a feature are present, such
   as for binutils libbfd, that has a mix of possible ways to detect according to the
   Linux distribution.
 
   Previously in some cases we had:
 
   Auto-detecting system features
   <SNIP>
   ...                                  libbfd: [ on  ]

   ...                        libbfd-liberty-z: [ on  ]
   <SNIP>
 
   Now for this case we show just the main feature:
 
   Auto-detecting system features
   <SNIP>
   ...                                  libbfd: [ on  ]

 - "perf lock" improvements:

     - Add -E/--entries option to limit the number of entries to
       display, say to ask for just the top 5 contended locks.

     - Add -q/--quiet option to suppress header and debug messages.

     - Add a 'perf test' kernel lock contention entry to test 'perf
       lock'.

 - "perf lock contention" improvements:

     - Ask BPF's bpf_get_stackid() to skip some callchain entries.

       The ones closer to the tooling are bpf related and not that
       interesting, the ones calling the locking function are the ones
       we're interested in, example of a full, unskipped callstack:

     - Allow changing the callstack depth and number of entries to skip.

Pull pci updates from Bjorn Helgaas:
 "Resource management:

   - Distribute spare resources to unconfigured hotplug bridges at
     boot-time (not just when hot-adding such a bridge), which makes
     hot-adding devices to docks work better.

   - Revert to a BAR assignment inherited from firmware only when the
     address is actually reachable via any upstream bridges, which fixes
     some cases where firmware doesn't configure all devices.

   - Add a sysfs interface to resize BARs so this can be done before
     assigning devices to a VM through VFIO.

  Power management:

   - Disable Precision Time Management for all devices on suspend to
     enable lower-power PM state. We previously did this just for Root
     Ports, which isn't enough because downstream devices can still
     generate PTM messages, which cause errors if it's disabled in the
     Root Port.

   - Save and restore the ASPM L1 PM Substates configuration for
     suspend/ resume. Previously this configuration was lost, so L1.x
     states likely stopped working after resume.

   - Check whether the L1 PM Substates Capability exists. If it didn't
     exist, we previously read junk and tried to configure L1 Substates
     based on that.

   - Fix the LTR_L1.2_THRESHOLD computation, which previously set a
     threshold for entering L1.2 that was too low in some cases.

   - Reduce the delay after transitions to or from D3cold by using
     usleep_range() rather than msleep(), which often slept for ~19ms
     instead of the 10ms normally required. The spec says 10ms is
     enough, but it's possible we could trip over devices that need a
     little more.

  Error handling:

   - Work around a BIOS bug that caused Intel Root Ports to advertise a
     Root Port Programmed I/O (RP PIO) log size of zero, which caused
     annoying warnings and prevented the kernel from dumping log
     registers for DPC errors.

  Qualcomm PCIe controller driver:

   - Add support for SC8280XP and SA8540P host controllers and SM8450
     endpoint controller.

   - Disable Master AXI clock on endpoint controllers to save power when
     link is idle or in L1.x.

   - Expose link state transition counts via debugfs to help debug
     issues with low-power states.

   - Add auto-loading module support.

  Synopsys DesignWare PCIe controller driver:

   - Remove a dependency on ZONE_DMA32 by allocating the MSI target page
     differently. There's more work to do related to eDMA controllers,
     so it's not completely settled"

This round looks fairly small comparing to the previous updates which includes
 mostly minor bug fixes. Nevertheless, as we've still interested in improving
 the stability, Chao added some debugging methods to diagnoze subtle runtime
 inconsistency problem.
 
 Enhancement
  - store all the corruption or failure reasons in superblock
  - detect meta inode, summary info, and block address inconsistency
  - increase the limit for reserve_root for low-end devices
  - add the number of compressed IO in iostat
 
 Bug fix
  - DIO write fix for zoned devices
  - do out-of-place writes for cold files
  - fix some stat updates (FS_CP_DATA_IO, dirty page count)
  - fix race condition on setting FI_NO_EXTENT flag
  - fix data races when freezing super
  - fix wrong continue condition check in GC
  - do not allow ATGC for LFS mode
 
 In addition, there're some code enhancement and clean-ups as usual.

27bc50fc90 - Yu Zhao's Multi-Gen LRU patches are here. They've been under test in 
linux-next for a couple of months without, to my knowledge, any negative
   reports (or any positive ones, come to that).
 
 - Also the Maple Tree from Liam R.  Howlett.  An overlapping range-based
   tree for vmas.  It it apparently slight more efficient in its own right,
   but is mainly targeted at enabling work to reduce mmap_lock contention.
 
   Liam has identified a number of other tree users in the kernel which
   could be beneficially onverted to mapletrees.
 
   Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat
   (https://lkml.kernel.org/r/CAOUHufZabH85CeUN-MEMgL8gJGzJEWUrkiM58JkTbBhh-jew0Q@mail.gmail.com).
   This has yet to be addressed due to Liam's unfortunately timed
   vacation.  He is now back and we'll get this fixed up.
 
 - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer.  It uses
   clang-generated instrumentation to detect used-unintialized bugs down to
   the single bit level.
 
   KMSAN keeps finding bugs.  New ones, as well as the legacy ones.
 
 - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of
   memory into THPs.
 
 - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support
   file/shmem-backed pages.
 
 - userfaultfd updates from Axel Rasmussen
 
 - zsmalloc cleanups from Alexey Romanov
 
 - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure
 
 - Huang Ying adds enhancements to NUMA balancing memory tiering mode's
   page promotion, with a new way of detecting hot pages.
 
 - memcg updates from Shakeel Butt: charging optimizations and reduced
   memory consumption.
 
 - memcg cleanups from Kairui Song.
 
 - memcg fixes and cleanups from Johannes Weiner.
 
 - Vishal Moola provides more folio conversions
 
 - Zhang Yi removed ll_rw_block() :(
 
 - migration enhancements from Peter Xu
 
 - migration error-path bugfixes from Huang Ying
 
 - Aneesh Kumar added ability for a device driver to alter the memory

Pull MM updates from Andrew Morton:

 - Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
   linux-next for a couple of months without, to my knowledge, any
   negative reports (or any positive ones, come to that).

 - Also the Maple Tree from Liam Howlett. An overlapping range-based
   tree for vmas. It it apparently slightly more efficient in its own
   right, but is mainly targeted at enabling work to reduce mmap_lock
   contention.

   Liam has identified a number of other tree users in the kernel which
   could be beneficially onverted to mapletrees.

   Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat
   at [1]. This has yet to be addressed due to Liam's unfortunately
   timed vacation. He is now back and we'll get this fixed up.

 - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses
   clang-generated instrumentation to detect used-unintialized bugs down
   to the single bit level.

   KMSAN keeps finding bugs. New ones, as well as the legacy ones.

 - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of
   memory into THPs.

 - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to
   support file/shmem-backed pages.

 - userfaultfd updates from Axel Rasmussen

 - zsmalloc cleanups from Alexey Romanov

 - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and
   memory-failure

 - Huang Ying adds enhancements to NUMA balancing memory tiering mode's
   page promotion, with a new way of detecting hot pages.

 - memcg updates from Shakeel Butt: charging optimizations and reduced
   memory consumption.

 - memcg cleanups from Kairui Song.

 - memcg fixes and cleanups from Johannes Weiner.

 - Vishal Moola provides more folio conversions

 - Zhang Yi removed ll_rw_block() :(

 - migration enhancements from Peter Xu

 - migration error-path bugfixes from Huang Ying

 - Aneesh Kumar added ability for a device driver to alter the memory
   tiering promotion paths. For optimizations by PMEM drivers, DRM
   drivers, etc.

 - vma merging improvements from Jakub Matěn.

 - NUMA hinting cleanups from David Hildenbrand.

Including:
 
 	- Removal of the bus_set_iommu() interface which became
 	  unnecesary because of IOMMU per-device probing
 
 	- Make the dma-iommu.h header private
 
 	- Intel VT-d changes from Lu Baolu:
 	  - Decouple PASID and PRI from SVA
 	  - Add ESRTPS & ESIRTPS capability check
 	  - Cleanups
 
 	- Apple DART support for the M1 Pro/MAX SOCs
 
 	- Support for AMD IOMMUv2 page-tables for the DMA-API layer. The
 	  v2 page-tables are compatible with the x86 CPU page-tables.
 	  Using them for DMA-API prepares support for hardware-assisted
 	  IOMMU virtualization
 
 	- Support for MT6795 Helio X10 M4Us in the Mediatek IOMMU driver
 
 	- Some smaller fixes and cleanups

cdf072acb5 Tracing updates for 6.1: 
Major changes:
 
  - Changed location of tracing repo from personal git repo to:
    git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git
 
  - Added Masami Hiramatsu as co-maintainer
 
  - Updated MAINTAINERS file to separate out FTRACE as it is
    more than just TRACING.
 
 Minor changes:
 
  - Added Mark Rutland as FTRACE reviewer
 
  - Updated user_events to make it on its way to remove the BROKEN tag.
    The changes should now be acceptable but will run it through
    a cycle and hopefully we can remove the BROKEN tag next release.
 
  - Added filtering to eprobes
 
  - Added a delta time to the benchmark trace event
 
  - Have the histogram and filter callbacks called via a switch
    statement instead of indirect functions. This speeds it up to
    avoid retpolines.
 
  - Add a way to wake up ring buffer waiters waiting for the
    ring buffer to fill up to its watermark.
 
  - New ioctl() on the trace_pipe_raw file to wake up ring buffer
    waiters.
 
  - Wake up waiters when the ring buffer is disabled.
    A reader may block when the ring buffer is disabled,
    but if it was blocked when the ring buffer is disabled
    it should then wake up.
 
 Fixes:
 
  - Allow splice to read partially read ring buffer pages
    Fixes splice never moving forward.
 
  - Fix inverted compare that made the "shortest" ring buffer
    wait queue actually the longest.
 
  - Fix a race in the ring buffer between resetting a page when
    a writer goes to another page, and the reader.
 
  - Fix ftrace accounting bug when function hooks are added at
    boot up before the weak functions are set to "disabled".
 
  - Fix bug that freed a user allocated snapshot buffer when
    enabling a tracer.
 
  - Fix possible recursive locks in osnoise tracer
 
  - Fix recursive locking direct functions
 
  - And other minor clean ups and fixes

The kernel size changes due to many factors, such as compiler
version, configuration, and the build environment. This makes
size comparison figures irrelevant to reader's setup.

Remove these figures and describe the effects of page owner
to the kernel size in general instead.

 Note that for-6.1-fixes was pulled into for-6.1 twice. Both were for

 Also, 8a693f7766f9 ("cgroup: Remove CFTYPE_PRESSURE") removes the flag used
 by PSI changes in the tip tree and the merged result won't compile due to
 the missing flag. Simply removing the struct init lines specifying the flag
 is the correct resolution. linux-next already contains the correct fix:

Merge tag 'slab-for-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull slab fixes from Vlastimil Babka:

 - The "common kmalloc v4" series [1] by Hyeonggon Yoo.

   While the plan after LPC is to try again if it's possible to get rid
   of SLOB and SLAB (and if any critical aspect of those is not possible
   to achieve with SLUB today, modify it accordingly), it will take a
   while even in case there are no objections.

   Meanwhile this is a nice cleanup and some parts (e.g. to the
   tracepoints) will be useful even if we end up with a single slab
   implementation in the future:

      - Improves the mm/slab_common.c wrappers to allow deleting
        duplicated code between SLAB and SLUB.

      - Large kmalloc() allocations in SLAB are passed to page allocator
        like in SLUB, reducing number of kmalloc caches.

      - Removes the {kmem_cache_alloc,kmalloc}_node variants of
        tracepoints, node id parameter added to non-_node variants.

 - Addition of kmalloc_size_roundup()

   The first two patches from a series by Kees Cook [2] that introduce
   kmalloc_size_roundup(). This will allow merging of per-subsystem
   patches using the new function and ultimately stop (ab)using ksize()
   in a way that causes ongoing trouble for debugging functionality and
   static checkers.

 - Wasted kmalloc() memory tracking in debugfs alloc_traces

   A patch from Feng Tang that enhances the existing debugfs
   alloc_traces file for kmalloc caches with information about how much
   space is wasted by allocations that needs less space than the
   particular kmalloc cache provides.

 - My series [3] to fix validation races for caches with enabled
   debugging:

      - By decoupling the debug cache operation more from non-debug
        fastpaths, extra locking simplifications were possible and thus
        done afterwards.

      - Additional cleanup of PREEMPT_RT specific code on top, by Thomas
        Gleixner.

      - A late fix for slab page leaks caused by the series, by Feng
        Tang.

 - Smaller fixes and cleanups:

      - Unneeded variable removals, by ye xingchen

      - A cleanup removing a BUG_ON() in create_unique_id(), by Chao Yu
