Andy Shevchenko 025e3b507a fbdev: ssd1307fb: Drop optional dependency
Only a single out of three devices need a PWM, so from driver it's
optional. Moreover it's a single driver in the entire kernel that
currently selects PWM. Unfortunately this selection is a root cause
of the circular dependencies when we want to enable optional PWM
for some other drivers that select GPIOLIB.

Sean Christopherson 549a715b98 KVM: x86: Add proper ReST tables for userspace MSR exits/flags
Add ReST formatting to the set of userspace MSR exits/flags so that the
resulting HTML docs generate a table instead of malformed gunk.  This
also fixes a warning that was introduced by a recent cleanup of the
relevant documentation (yay copy+paste).

Tiezhu Yang 818448e9cf perf tools: Use "grep -E" instead of "egrep"
The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:

	egrep: warning: egrep is obsolescent; using grep -E

fix this up by moving the related file to use "grep -E" instead.

  sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/perf`

Here are the steps to install the latest grep:

  wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
  tar xf grep-3.8.tar.gz
  cd grep-3.8 && ./configure && make
  sudo make install
  export PATH=/usr/local/bin:$PATH

Namhyung Kim c587e77e10 perf stat: Do not delay the workload with --delay
The -D/--delay option is to delay the measure after the program starts.
But the current code goes to sleep before starting the program so the
program is delayed too.  This is not the intention, let's fix it.

Before:

  $ time sudo ./perf stat -a -e cycles -D 3000 sleep 4
  Events disabled
  Events enabled

   Performance counter stats for 'system wide':

       4,326,949,337      cycles

         4.007494118 seconds time elapsed

  real	0m7.474s
  user	0m0.356s
  sys	0m0.120s

It ran the workload for 4 seconds and gave the 3 second delay.  So it
should skip the first 3 second and measure the last 1 second only.  But
as you can see, it delays 3 seconds and ran the workload after that for
4 seconds.  So the total time (real) was 7 seconds.

After:

  $ time sudo ./perf stat -a -e cycles -D 3000 sleep 4
  Events disabled
  Events enabled

   Performance counter stats for 'system wide':

       1,063,551,013      cycles

         1.002769510 seconds time elapsed

  real	0m4.484s
  user	0m0.385s
  sys	0m0.086s

The bug was introduced when it changed enablement of system-wide events
with a command line workload.  But it should've considered the initial
delay case.  The code was reworked since then (in bb8bc52e75) so I'm
afraid it won't be applied cleanly.

Ian Rogers 5f8f95673f perf evlist: Remove group option.
The group option predates grouping events using curly braces added in
commit 89efb02950 ("perf tools: Add support to parse event group

The --group option was retained for legacy support (in August
2012) but keeping it adds complexity.

Pull XFS updates from Darrick Wong:
 "The highlight of this is a batch of fixes for the online metadata
  checking code as we start the loooong march towards merging online
  repair. I aim to merge that in time for the 2023 LTS.

  There are also a large number of data corruption and race condition
  fixes in this patchset. Most notably fixed are write() calls to
  unwritten extents racing with writeback, which required some late(r
  than I prefer) code changes to iomap to support the necessary
  revalidations. I don't really like iomap changes going in past -rc4,
  but Dave and I have been working on it long enough that I chose to
  push it for 6.2 anyway.

  There are also a number of other subtle problems fixed, including the
  log racing with inode writeback to write inodes with incorrect link
  count to disk; file data mapping corruptions as a result of incorrect
  lock cycling when attaching dquots; refcount metadata corruption if
  one actually manages to share a block 2^32 times; and the log
  clobbering cow staging extents if they were formerly metadata blocks.

  Summary:

   - Fix a race condition w.r.t. percpu inode free counters

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Squash portdrv_{core,pci}.c into portdrv.c to ease maintenance and
     make more things static.

   - Make portdrv bind to Switch Ports that have AER. Previously, if
     these Ports lacked MSI/MSI-X, portdrv failed to bind, which meant
     the Ports couldn't be suspended to low-power states. AER on these
     Ports doesn't use interrupts, and the AER driver doesn't need to
     claim them.

   - Assign PCI domain IDs using ida_alloc(), which makes host bridge
     add/remove work better.

  Resource management:

   - To work better with recent BIOSes that use EfiMemoryMappedIO for
     PCI host bridge apertures, remove those regions from the E820 map
     (E820 entries normally prevent us from allocating BARs). In v5.19,
     we added some quirks to disable E820 checking, but that's not very
     maintainable. EfiMemoryMappedIO means the OS needs to map the
     region for use by EFI runtime services; it shouldn't prevent OS
     from using it.

  PCIe native device hotplug:

   - Build pciehp by default if USB4 is enabled, since Thunderbolt/USB4
     PCIe tunneling depends on native PCIe hotplug.

   - Enable Command Completed Interrupt only if supported to avoid user
     confusion from lspci output that says this is enabled but not
     supported.

   - Prevent pciehp from binding to Switch Upstream Ports; this happened
     because of interaction with acpiphp and caused devices below the
     Upstream Port to disappear.

  Power management:

   - Convert AGP drivers to generic power management. We hope to remove
     legacy power management from the PCI core eventually.

  Virtualization:

   - Fix pci_device_is_present(), which previously always returned
     "false" for VFs, causing virtio hangs when unbinding the driver.

  Miscellaneous:

   - Convert drivers to gpiod API to prepare for dropping some legacy
     code.

   - Fix DOE fencepost error for the maximum data object length.

  Baikal-T1 PCIe controller driver:

   - Add driver and DT bindings.

  Broadcom STB PCIe controller driver:

   - Enable Multi-MSI.

   - Delay 100ms after PERST# deassert to allow power and clocks to
     stabilize.

   - Configure Read Completion Boundary to 64 bytes.

  Freescale i.MX6 PCIe controller driver:

   - Initialize PHY before deasserting core reset to fix a regression in
     v6.0 on boards where the PHY provides the reference.

   - Fix imx6sx and imx8mq clock names in DT schema.

  Intel VMD host bridge driver:

   - Fix Secondary Bus Reset on VMD bridges, which allows reset of NVMe
     SSDs in VT-d pass-through scenarios.

   - Disable MSI remapping, which gets re-enabled by firmware during
     suspend/resume.

  MediaTek PCIe Gen3 controller driver:

   - Add MT7986 and MT8195 support.

  Qualcomm PCIe controller driver:

   - Add SC8280XP/SA8540P basic interconnect support.

  Rockchip DesignWare PCIe controller driver:

   - Base DT schema on common Synopsys schema.

  Synopsys DesignWare PCIe core:

   - Collect DT items shared between Root Port and Endpoint (PERST GPIO,
     PHY info, clocks, resets, link speed, number of lanes, number of
     iATU windows, interrupt info, etc) to snps,dw-pcie-common.yaml.

   - Add dma-ranges support for Root Ports and Endpoints.

   - Consolidate DT resource retrieval for "dbi", "dbi2", "atu", etc. to
     reduce code duplication.

   - Add generic names for clocks and resets to encourage more
     consistent naming across drivers using DesignWare IP.

   - Stop advertising PTM Responder role for Endpoints, which aren't
     allowed to be responders.

  TI J721E PCIe driver:

   - Add j721s2 host mode ID to DT schema.

   - Add interrupt properties to DT schema.

  Toshiba Visconti PCIe controller driver:

   - Fix interrupts array max constraints in DT schema"

Linus Torvalds 08cdc21579 iommufd for 6.2
iommufd is the user API to control the IOMMU subsystem as it relates to
 managing IO page tables that point at user space memory.
 
 It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO
 container) which is the VFIO specific interface for a similar idea.
 
 We see a broad need for extended features, some being highly IOMMU device
 specific:
  - Binding iommu_domain's to PASID/SSID
  - Userspace IO page tables, for ARM, x86 and S390
  - Kernel bypassed invalidation of user page tables
  - Re-use of the KVM page table in the IOMMU
  - Dirty page tracking in the IOMMU
  - Runtime Increase/Decrease of IOPTE size
  - PRI support with faults resolved in userspace
 
 Many of these HW features exist to support VM use cases - for instance the
 combination of PASID, PRI and Userspace IO Page Tables allows an
 implementation of DMA Shared Virtual Addressing (vSVA) within a
 guest. Dirty tracking enables VM live migration with SRIOV devices and
 PASID support allow creating "scalable IOV" devices, among other things.
 
 As these features are fundamental to a VM platform they need to be
 uniformly exposed to all the driver families that do DMA into VMs, which
 is currently VFIO and VDPA.

Steven Rostedt (Google) eb9d58947d tracing: Fix cpumask() example typo
The sample code for using cpumask used the wrong field for the
__get_cpumask() helper. It used "cpus" which is the bitmask (but would
still give a proper example) instead of the "cpum" that was there to be
used.

Although it produces the same output, fix it, because it's an example and
is confusing in how to properly use the cpumask() macro.

Guilherme G. Piccoli ea47666ca4 tracing: Improve panic/die notifiers
Currently the tracing dump_on_oops feature is implemented through
separate notifiers, one for die/oops and the other for panic;
given they have the same functionality, let's unify them.

Also improve the function comment and change the priority of the
notifier to make it execute earlier, avoiding showing useless trace
data (like the callback names for the other notifiers); finally,
we also removed an unnecessary header inclusion.

Ard Biesheuvel 38792972de ftrace: Allow WITH_ARGS flavour of graph tracer with shadow call stack
The recent switch on arm64 from DYNAMIC_FTRACE_WITH_REGS to
DYNAMIC_FTRACE_WITH_ARGS failed to take into account that we currently
require the former in order to allow the function graph tracer to be
enabled in combination with shadow call stacks. This means that this is
no longer permitted at all, in spite of the fact that either flavour of
ftrace works perfectly fine in this combination.

So permit WITH_ARGS as well as WITH_REGS.

Dai Ngo 75333d48f9 NFSD: fix use-after-free in __nfs42_ssc_open()
Problem caused by source's vfsmount being unmounted but remains
on the delayed unmount list. This happens when nfs42_ssc_open()
return errors.

Fixed by removing nfsd4_interssc_connect(), leave the vfsmount
for the laundromat to unmount when idle time expires.

We don't need to call nfs_do_sb_deactive when nfs42_ssc_open
return errors since the file was not opened so nfs_server->active
was not incremented. Same as in nfsd4_copy, if we fail to
launch nfsd4_do_async_copy thread then there's no need to
call nfs_do_sb_deactive

not need this eFuse range to function properly

Update the bindings for the k3_j72xx_bandgap thermal driver so other
devices will only need two register ranges

Bryan Brattlof 366444ebe7 thermal/drivers/k3_j72xx_bandgap: Map fuse_base only for erratum workaround
Some of TI's J721E SoCs require a software trimming procedure for the
temperature monitors to function properly. To determine if a particular
J721E is not affected by this erratum, both bits in the WKUP_SPARE_FUSE0
region must be set. Other SoCs, not affected by this erratum, will not
need this region.

Map the 'fuse_base' region only when the erratum fix is needed.

Christian Marangi 89992d95ed thermal/drivers/qcom/tsens: Rework debugfs file structure
The current tsens debugfs structure is composed by:
- a tsens dir in debugfs with a version file
- a directory for each tsens istance with sensors file to dump all the
  sensors value.

This works on the assumption that we have the same version for each
istance but this assumption seems fragile and with more than one tsens
istance results in the version file not tracking each of them.

A better approach is to just create a subdirectory for each tsens
istance and put there version and sensors debugfs file.

Using this new implementation results in less code since debugfs entry
are created only on successful tsens probe.
