Merge tag 'xfs-5.13-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
 "The notable user-visible addition this cycle is ability to remove
  space from the last AG in a filesystem. This is the first of many
  changes needed for full-fledged support for shrinking a filesystem.
  Still needed are (a) the ability to reorganize files and metadata away
  from the end of the fs; (b) the ability to remove entire allocation
  groups; (c) shrink support for realtime volumes; and (d) thorough
  testing of (a-c).

  There are a number of performance improvements in this code drop: Dave
  streamlined various parts of the buffer logging code and reduced the
  cost of various debugging checks, and added the ability to pre-create
  the xattr structures while creating files. Brian eliminated
  transaction reservations that were being held across writeback (thus
  reducing livelock potential.

  Other random pieces: Pavel fixed the repetitve warnings about
  deprecated mount options, I fixed online fsck to behave itself when a
  readonly remount comes in during scrub, and refactored various other
  parts of that code, Christoph contributed a lot of refactoring this
  cycle. The xfs_icdinode structure has been absorbed into the (incore)
  xfs_inode structure, and the format and flags handling around
  xfs_inode_fork structures has been simplified. Chandan provided a
  number of fixes for extent count overflow related problems that have
  been shaken out by debugging knobs added during 5.12.

  Summary:

   - Various minor fixes in online scrub.

   - Prevent metadata files from being automatically inactivated.

   - Validate btree heights by the computed per-btree limits.

   - Don't warn about remounting with deprecated mount options.

   - Initialize attr forks at create time if we suspect we're going to
     need to store them.

   - Reduce memory reallocation workouts in the logging code.

   - Fix some theoretical math calculation errors in logged buffers that
     span multiple discontig memory ranges but contiguous ondisk
     regions.

   - Speedups in dirty buffer bitmap handling.

   - Reduce debug overhead in directory checking code.

   - Begin to handle the permanent loss of the very end of a filesystem.

   - Fold struct xfs_icdinode into xfs_inode.

35655ceb31 Here's a collection of largely clk driver updates for the merge window. The 
usual suspects are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and
 Rockchip, but it feels pretty light on commits. There's only one real commit to
 the framework core and that's to consolidate code. Otherwise the diffstat is
 dominated by many Qualcomm clk driver patches that modernize the driver for the
 proper way of speciying clk parents. That's shifting data around, which could
 subtly break things so I'll be on the lookout for fixes.
 
 New Drivers:
  - Proper clk driver for Mediatek MT7621 SoCs
  - Support for the clock controller on the new Rockchip rk3568
 
 Updates:
  - Simplify Zynq Kconfig dependencies
  - Use clk_hw pointers in socfpga driver
  - Cleanup parent data in qcom clk drivers
  - Some cleanups for rk3399 modularization
  - Fix reparenting of i.MX UART clocks by initializing only the ones

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "Here's a collection of largely clk driver updates. The usual suspects
  are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and Rockchip,
  but it feels pretty light on commits.

  There's only one real commit to the framework core and that's to
  consolidate code. Otherwise the diffstat is dominated by many Qualcomm
  clk driver patches that modernize the driver for the proper way of
  speciying clk parents. That's shifting data around, which could subtly
  break things so I'll be on the lookout for fixes.

  New Drivers:
   - Proper clk driver for Mediatek MT7621 SoCs
   - Support for the clock controller on the new Rockchip rk3568

  Updates:
   - Simplify Zynq Kconfig dependencies
   - Use clk_hw pointers in socfpga driver
   - Cleanup parent data in qcom clk drivers
   - Some cleanups for rk3399 modularization
   - Fix reparenting of i.MX UART clocks by initializing only the ones
     associated to stdout
   - Correct the PCIE clocks for i.MX8MP and i.MX8MQ
   - Make i.MX LPCG and SCU clocks return on registering failure
   - Kernel doc fixes
   - Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N
   - Add timer (TMU) clocks on Renesas R-Car H3 ES1.0
   - Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on
     Renesas R-Car V3U
   - Sigma-delta modulation on Allwinner V3s audio PLL"

Merge tag 'for-5.13/io_uring-2021-04-27' of git://git.kernel.dk/linux-block

Pull io_uring updates from Jens Axboe:

 - Support for multi-shot mode for POLL requests

 - More efficient reference counting. This is shamelessly stolen from
   the mm side. Even though referencing is mostly single/dual user, the
   128 count was retained to keep the code the same. Maybe this
   should/could be made generic at some point.

 - Removal of the need to have a manager thread for each ring. The
   manager threads only job was checking and creating new io-threads as
   needed, instead we handle this from the queue path.

 - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE. Since 5.12, this
   thread is "just" a regular application thread, so no need to restrict
   use of it anymore.

 - Cleanup of how internal async poll data lifetime is managed.

 - Fix for syzbot reported crash on SQPOLL cancelation.

 - Make buffer registration more like file registrations, which includes
   flexibility in avoiding full set unregistration and re-registration.

 - Fix for io-wq affinity setting.

 - Be a bit more defensive in task->pf_io_worker setup.

 - Various SQPOLL fixes.

 - Cleanup of SQPOLL creds handling.

 - Improvements to in-flight request tracking.

 - File registration cleanups.

 - Tons of cleanups and little fixes

16b3d0cf5b Scheduler updates for this cycle are: 
- Clean up SCHED_DEBUG: move the decades old mess of sysctl, procfs and debugfs interfaces
    to a unified debugfs interface.
 
  - Signals: Allow caching one sigqueue object per task, to improve performance & latencies.
 
  - Improve newidle_balance() irq-off latencies on systems with a large number of CPU cgroups.
 
  - Improve energy-aware scheduling
 
  - Improve the PELT metrics for certain workloads
 
  - Reintroduce select_idle_smt() to improve load-balancing locality - but without the previous
    regressions
 
  - Add 'scheduler latency debugging': warn after long periods of pending need_resched. This
    is an opt-in feature that requires the enabling of the LATENCY_WARN scheduler feature,
    or the use of the resched_latency_warn_ms=xx boot parameter.
 
  - CPU hotplug fixes for HP-rollback, and for the 'fail' interface. Fix remaining
    balance_push() vs. hotplug holes/races
 
  - PSI fixes, plus allow /proc/pressure/ files to be written by CAP_SYS_RESOURCE tasks as well
 
  - Fix/improve various load-balancing corner cases vs. capacity margins
 
  - Fix sched topology on systems with NUMA diameter of 3 or above
 
  - Fix PF_KTHREAD vs to_kthread() race
 
  - Minor rseq optimizations
 
  - Misc cleanups, optimizations, fixes and smaller updates

42dec9a936 Perf events changes in this cycle were: 
- Improve Intel uncore PMU support:
 
      - Parse uncore 'discovery tables' - a new hardware capability enumeration method
        introduced on the latest Intel platforms. This table is in a well-defined PCI
        namespace location and is read via MMIO. It is organized in an rbtree.
 
        These uncore tables will allow the discovery of standard counter blocks, but
        fancier counters still need to be enumerated explicitly.
 
      - Add Alder Lake support
 
      - Improve IIO stacks to PMON mapping support on Skylake servers
 
  - Add Intel Alder Lake PMU support - which requires the introduction of 'hybrid' CPUs
    and PMUs. Alder Lake is a mix of Golden Cove ('big') and Gracemont ('small' - Atom derived)
    cores.
 
    The CPU-side feature set is entirely symmetrical - but on the PMU side there's
    core type dependent PMU functionality.
 
  - Reduce data loss with CPU level hardware tracing on Intel PT / AUX profiling, by
    fixing the AUX allocation watermark logic.
 
  - Improve ring buffer allocation on NUMA systems
 
  - Put 'struct perf_event' into their separate kmem_cache pool
 
  - Add support for synchronous signals for select perf events. The immediate motivation
    is to support low-overhead sampling-based race detection for user-space code. The
    feature consists of the following main changes:
 
     - Add thread-only event inheritance via perf_event_attr::inherit_thread, which limits
       inheritance of events to CLONE_THREAD.
 
     - Add the ability for events to not leak through exec(), via perf_event_attr::remove_on_exec.
 
     - Allow the generation of SIGTRAP via perf_event_attr::sigtrap, extend siginfo with an u64
       ::si_perf, and add the breakpoint information to ::si_addr and ::si_perf if the event is
       PERF_TYPE_BREAKPOINT.
 
    The siginfo support is adequate for breakpoints right now - but the new field can be used
    to introduce support for other types of metadata passed over siginfo as well.
 
  - Misc fixes, cleanups and smaller updates.

 "The usual lots of work all over the place.

  i915 has gotten some Alderlake work and prelim DG1 code, along with a

  other fixes.

1e9599dfc4 linux-kselftest-kunit-5.13-rc1 
This KUnit update for Linux 5.13-rc1 consists of several fixes and
 new feature to support failure from dynamic analysis tools such as
 UBSAN and fake ops for testing.
 
 - a fake ops struct for testing a "free" function to complain if it
   was called with an invalid argument, or caught a double-free. Most
   return void and have no normal means of signalling failure
   (e.g. super_operations, iommu_ops, etc.).

 "Several fixes and a new feature to support failure from dynamic
  analysis tools such as UBSAN and fake ops for testing.

   - a fake ops struct for testing a "free" function to complain if it
     was called with an invalid argument, or caught a double-free. Most
     return void and have no normal means of signalling failure (e.g.
     super_operations, iommu_ops, etc.)"

Merge tag 'printk-for-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

Pull printk updates from Petr Mladek:

 - Stop synchronizing kernel log buffer readers by logbuf_lock. As a
   result, the access to the buffer is fully lockless now.

   Note that printk() itself still uses locks because it tries to flush
   the messages to the console immediately. Also the per-CPU temporary
   buffers are still there because they prevent infinite recursion and
   serialize backtraces from NMI. All this is going to change in the
   future.

 - kmsg_dump API rework and cleanup as a side effect of the logbuf_lock
   removal.

 - Make bstr_printf() aware that %pf and %pF formats could deference the
   given pointer.

 - Show also page flags by %pGp format.

 - Clarify the documentation for plain pointer printing.

 - Do not show no_hash_pointers warning multiple times.

 - Update Senozhatsky email address.

916a75965e kgdb patches for 5.13 
Exclusively tidy ups this cycle. Most of them are thanks to Sumit Garg
 and, as it happens, the clean ups do result in a slight increase in
 the line count. This is due to registering kdb commands using data
 structures rather than function calls which, in turn, simplifies the
 memory management during command registration.
 
 In addition to changes to command registration we also have some dead
 code removal, a clearer implementation of environment variable handling
 and a typo fix.

 - fix two memory leaks in zcrypt driver.
 
 - expose PCI device UID as index, including an indicator if the uid is
   unique.
 
 - remove some oprofile leftovers.
 
 - improve stack unwinder tests.
 
 - don't use gcc atomic builtins anymore, just like all other
   architectures. Even though I'm sure the current code is ok, I
   totally dislike that s390 is the only architecture being special
   here; especially considering that there was a lengthly discussion
   about this topic and the outcome was not to use the builtins.
   Therefore open-code atomic ops again with inline assembly and switch
   to gcc builtins as soon as other architectures are doing.
 
 - couple of other changes to atomic and cmpxchg, and use
   atomic-instrumented.h for KASAN.
 
 - separate zbus creation, registration, and scanning in our PCI code
   which allows for cleaner and easier handling.
 
 - a rather large change to the vfio-ap code to fix circular locking
   dependencies when updating crypto masks.
 
 - move QAOB handling from qdio layer down to drivers.
 
 - add CRW inject facility to common I/O layer. This adds debugs files
   which allow to generate artificial events from user space for
   testing purposes.
 
 - increase SCLP console line length from 80 to 320 characters to avoid
   odd wrapped lines.
 
 - add protected virtualization guest and host indication files, which
   indicate either that a guest is running in pv mode or if the
   hypervisor is capable of starting pv guests.

c6536676c7 - turn the stack canary into a normal __percpu variable on 32-bit which 
gets rid of the LAZY_GS stuff and a lot of code.
 
 - Add an insn_decode() API which all users of the instruction decoder
 should preferrably use. Its goal is to keep the details of the
 instruction decoder away from its users and simplify and streamline how
 one decodes insns in the kernel. Convert its users to it.
 
 - kprobes improvements and fixes
 
 - Set the maximum DIE per package variable on Hygon
 
 - Rip out the dynamic NOP selection and simplify all the machinery around
 selecting NOPs. Use the simplified NOPs in objtool now too.
 
 - Add Xeon Sapphire Rapids to list of CPUs that support PPIN
 
 - Simplify the retpolines by folding the entire thing into an
 alternative now that objtool can handle alternatives with stack
 ops. Then, have objtool rewrite the call to the retpoline with the
 alternative which then will get patched at boot time.
 
 - Document Intel uarch per models in intel-family.h
 
 - Make Sub-NUMA Clustering topology the default and Cluster-on-Die the
 exception on Intel.

   gets rid of the LAZY_GS stuff and a lot of code.

 - Add an insn_decode() API which all users of the instruction decoder
   should preferrably use. Its goal is to keep the details of the
   instruction decoder away from its users and simplify and streamline
   how one decodes insns in the kernel. Convert its users to it.

 - kprobes improvements and fixes

 - Set the maximum DIE per package variable on Hygon

 - Rip out the dynamic NOP selection and simplify all the machinery
   around selecting NOPs. Use the simplified NOPs in objtool now too.

 - Add Xeon Sapphire Rapids to list of CPUs that support PPIN

 - Simplify the retpolines by folding the entire thing into an
   alternative now that objtool can handle alternatives with stack ops.
   Then, have objtool rewrite the call to the retpoline with the
   alternative which then will get patched at boot time.

 - Document Intel uarch per models in intel-family.h

 - Make Sub-NUMA Clustering topology the default and Cluster-on-Die the
   exception on Intel.

e7c6e405e1 Fix misc new gcc warnings 
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably
"-Wstringop-overread" and "-Warray-parameter".

Both of them cause what seem to be valid warnings in the kernel, where
we have array size mismatches in function arguments (that are no longer
just silently converted to a pointer to element, but actually checked).

This fixes most of the trivial ones, by making the function declaration
match the function definition, and in the case of intel_pm.c, removing
the over-specified array size from the argument declaration.

At least one 'stringop-overread' warning remains in the i915 driver, but
that one doesn't have the same obvious trivial fix, and may or may not
actually be indicative of a bug.

[ It was a mistake to upgrade one of my machines to Fedora 34 while
  being busy with the merge window, but if this is the extent of the
  compiler upgrade problems, things are better than usual    - Linus ]

   is working on a proper AppArmor patch, in the meantime this set of

Pull AFS updates from David Howells:
 "Use the new netfs lib.

  Begin the process of overhauling the use of the fscache API by AFS and
  the introduction of support for features such as Transparent Huge
  Pages (THPs).

   - Add some support for THPs, including using core VM helper functions
     to find details of pages.

   - Use the ITER_XARRAY I/O iterator to mediate access to the pagecache
     as this handles THPs and doesn't require allocation of large bvec
     arrays.

   - Delegate address_space read/pre-write I/O methods for AFS to the
     netfs helper library. A method is provided to the library that
     allows it to issue a read against the server.

     This includes a change in use for PG_fscache (it now indicates a
     DIO write in progress from the marked page), so a number of waits
     need to be deployed for it.

   - Split the core AFS writeback function to make it easier to modify
     in future patches to handle writing to the cache. [This might
     feasibly make more sense moved out into my fscache-iter branch].

  I've tested these with "xfstests -g quick" against an AFS volume
  (xfstests needs patching to make it work). With this, AFS without a
  cache passes all expected xfstests; with a cache, there's an extra
  failure, but that's also there before these patches. Fixing that
  probably requires a greater overhaul (as can be found on my
  fscache-iter branch, but that's for a later time).

  Thanks should go to Marc Dionne and Jeff Altman of AuriStor for
  exercising the patches in their test farm also"

Merge tag 'netfs-lib-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull network filesystem helper library updates from David Howells:
 "Here's a set of patches for 5.13 to begin the process of overhauling
  the local caching API for network filesystems. This set consists of
  two parts:

  (1) Add a helper library to handle the new VM readahead interface.

      This is intended to be used unconditionally by the filesystem
      (whether or not caching is enabled) and provides a common
      framework for doing caching, transparent huge pages and, in the
      future, possibly fscrypt and read bandwidth maximisation. It also
      allows the netfs and the cache to align, expand and slice up a
      read request from the VM in various ways; the netfs need only
      provide a function to read a stretch of data to the pagecache and
      the helper takes care of the rest.

  (2) Add an alternative fscache/cachfiles I/O API that uses the kiocb
      facility to do async DIO to transfer data to/from the netfs's
      pages, rather than using readpage with wait queue snooping on one
      side and vfs_write() on the other. It also uses less memory, since
      it doesn't do buffered I/O on the backing file.

      Note that this uses SEEK_HOLE/SEEK_DATA to locate the data
      available to be read from the cache. Whilst this is an improvement
      from the bmap interface, it still has a problem with regard to a
      modern extent-based filesystem inserting or removing bridging
      blocks of zeros. Fixing that requires a much greater overhaul.

  This is a step towards overhauling the fscache API. The change is
  opt-in on the part of the network filesystem. A netfs should not try
  to mix the old and the new API because of conflicting ways of handling
  pages and the PG_fscache page flag and because it would be mixing DIO
  with buffered I/O. Further, the helper library can't be used with the
  old API.

  This does not change any of the fscache cookie handling APIs or the
  way invalidation is done at this time.

  In the near term, I intend to deprecate and remove the old I/O API
  (fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(),
  fscache_write_page() and fscache_uncache_page()) and eventually
  replace most of fscache/cachefiles with something simpler and easier
  to follow.

  This patchset contains the following parts:

   - Some helper patches, including provision of an ITER_XARRAY iov
     iterator and a function to do readahead expansion.

   - Patches to add the netfs helper library.

   - A patch to add the fscache/cachefiles kiocb API.

   - A pair of patches to fix some review issues in the ITER_XARRAY and
     read helpers as spotted by Al and Willy.

  Jeff Layton has patches to add support in Ceph for this that he
  intends for this merge window. I have a set of patches to support AFS
  that I will post a separate pull request for.

  With this, AFS without a cache passes all expected xfstests; with a
  cache, there's an extra failure, but that's also there before these
  patches. Fixing that probably requires a greater overhaul. Ceph also
  passes the expected tests.

  I also have patches in a separate branch to tidy up the handling of
  PG_fscache/PG_private_2 and their contribution to page refcounting in
  the core kernel here, but I haven't included them in this set and will
  route them separately"

Merge tag 'fs.idmapped.helpers.v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull fs mapping helper updates from Christian Brauner:
 "This adds kernel-doc to all new idmapping helpers and improves their
  naming which was triggered by a discussion with some fs developers.
  Some of the names are based on suggestions by Vivek and Al.

  Also remove the open-coded permission checking in a few places with
  simple helpers. Overall this should lead to more clarity and make it
  easier to maintain"

adaeb718d4 vfio/gvt: fix DRM_I915_GVT dependency on VFIO_MDEV 
The Kconfig dependency is incomplete since DRM_I915_GVT is a 'bool'
symbol that depends on the 'tristate' VFIO_MDEV. This allows a
configuration with VFIO_MDEV=m, DRM_I915_GVT=y and DRM_I915=y that
causes a link failure:

x86_64-linux-ld: drivers/gpu/drm/i915/gvt/gvt.o: in function `available_instances_show':
gvt.c:(.text+0x67a): undefined reference to `mtype_get_parent_dev'
x86_64-linux-ld: gvt.c:(.text+0x6a5): undefined reference to `mtype_get_type_group_id'
x86_64-linux-ld: drivers/gpu/drm/i915/gvt/gvt.o: in function `description_show':
gvt.c:(.text+0x76e): undefined reference to `mtype_get_parent_dev'
x86_64-linux-ld: gvt.c:(.text+0x799): undefined reference to `mtype_get_type_group_id'

Clarify the dependency by specifically disallowing the broken
configuration. If VFIO_MDEV is built-in, it will work, but if
VFIO_MDEV=m, the i915 driver cannot be built-in here.

Fixes: 07e543f4f9 ("vfio/gvt: Make DRM_I915_GVT depend on VFIO_MDEV")
Fixes: 9169cff168 ("vfio/mdev: Correct the function signatures for the mdev_type_attributes")
