a7f4a27f2f ide: Use pr_warn instead of pr_warning 
As said in commit f2c2cbcc35 ("powerpc: Use pr_warn instead of
pr_warning"), removing pr_warning so all logging messages use a
consistent <prefix>_warn style. Let's do it.

085a3a8fdf ABI: Update dev-kmsg documentation to match current kernel behaviour 
Commit 5aa068ea40 ("printk: remove games with previous record flags")
abolished the practice of setting the log flag to 'c' for the first
continuation line and '+' for subsequent lines. Now all continuation
lines are flagged with 'c' and '+' is never used.

Update the 'dev-kmsg' documentation to remove the reference to the
obsolete '+' flag. In addition, state explicitly that only 8 bits of the
<N> syslog prefix are used for the facility number when writing to
/dev/kmsg.

35c35493b0 printk: Replace strncmp() with str_has_prefix() 
strncmp(str, const, len) is error-prone because len is easy to have typo.
An example is the hard-coded len has counting error or sizeof(const)
forgets - 1.

So we prefer using newly introduced str_has_prefix() to substitute
such strncmp() to make code better.

36594b317c vsprintf: Prevent crash when dereferencing invalid pointers for %pD 
Commit 3e5903eb9c ("vsprintf: Prevent crash when dereferencing invalid
pointers") prevents most crash except for %pD.
There is an additional pointer dereferencing before dentry_name.

At least, vma->file can be NULL and be passed to printk %pD in
print_bad_pte, which can cause crash.

This patch fixes it with introducing a new file_dentry_name.

c9dccacfcc printk: Do not lose last line in kmsg buffer dump 
kmsg_dump_get_buffer() is supposed to select all the youngest log
messages which fit into the provided buffer.  It determines the correct
start index by using msg_print_text() with a NULL buffer to calculate
the size of each entry.  However, when performing the actual writes,
msg_print_text() only writes the entry to the buffer if the written len
is lesser than the size of the buffer.  So if the lengths of the
selected youngest log messages happen to precisely fill up the provided
buffer, the last log message is not included.

We don't want to modify msg_print_text() to fill up the buffer and start
returning a length which is equal to the size of the buffer, since
callers of its other users, such as kmsg_dump_get_line(), depend upon
the current behaviour.

Instead, fix kmsg_dump_get_buffer() to compensate for this.

For example, with the following two final prints:

[    6.427502] AAAAAAAAAAAAA
[    6.427769] BBBBBBBB12345

A dump of a 64-byte buffer filled by kmsg_dump_get_buffer(), before this

Pull perf updates from Ingo Molnar:
 "The main changes in this cycle on the kernel side were:

   - CPU PMU and uncore driver updates to Intel Snow Ridge, IceLake,
     KabyLake, AmberLake and WhiskeyLake CPUs.

   - Rework the MSR probing infrastructure to make it more robust, make
     it work better on virtualized systems and to better expose it on
     sysfs.

   - Rework PMU attributes group support based on the feedback from
     Greg. The core sysfs patch that adds sysfs_update_groups() was
     acked by Greg.

  There's a lot of perf tooling changes as well, all around the place:

   - vendor updates to Intel, cs-etm (ARM), ARM64, s390,

   - various enhancements to Intel PT tooling support:
      - Improve CBR (Core to Bus Ratio) packets support.
      - Export power and ptwrite events to sqlite and postgresql.
      - Add support for decoding PEBS via PT packets.
      - Add support for samples to contain IPC ratio, collecting cycles
        information from CYC packets, showing the IPC info periodically
      - Allow using time ranges

   - lots of updates to perf pmu, perf stat, perf trace, eBPF support,
     perf record, perf diff, etc. - please see the shortlog and Git log
     for details"

Pull power management updates from Rafael Wysocki:
 "These update PCI and ACPI power management (improved handling of ACPI
  power resources and PCIe link delays, fixes related to corner cases,
  hibernation handling rework), fix and extend the operating performance
  points (OPP) framework, add new cpufreq drivers for Raspberry Pi and
  imx8m chips, update some other cpufreq drivers, clean up assorted
  pieces of PM code and documentation and update tools.

  Specifics:

   - Improve the handling of shared ACPI power resources in the PCI bus
     type layer (Mika Westerberg).

   - Make the PCI layer take link delays required by the PCIe spec into
     account as appropriate and avoid polling devices in D3cold for PME
     (Mika Westerberg).

   - Fix some corner case issues in ACPI device power management and in
     the PCI bus type layer, optimiza and clean up the handling of
     runtime-suspended PCI devices during system-wide transitions to
     sleep states (Rafael Wysocki).

   - Rework hibernation handling in the ACPI core and the PCI bus type
     to resume runtime-suspended devices before hibernation (which
     allows some functional problems to be avoided) and fix some ACPI
     power management issues related to hiberation (Rafael Wysocki).

   - Extend the operating performance points (OPP) framework to support
     a wider range of devices (Rajendra Nayak, Stehpen Boyd).

   - Fix issues related to genpd_virt_devs and issues with platforms
     using the set_opp() callback in the OPP framework (Viresh Kumar,
     Dmitry Osipenko).

   - Add new cpufreq driver for Raspberry Pi (Nicolas Saenz Julienne).

   - Add new cpufreq driver for imx8m and imx7d chips (Leonard Crestez).

   - Fix and clean up the pcc-cpufreq, brcmstb-avs-cpufreq, s5pv210, and
     armada-37xx cpufreq drivers (David Arcari, Florian Fainelli, Paweł
     Chmiel, YueHaibing).

   - Clean up and fix the cpufreq core (Viresh Kumar, Daniel Lezcano).

   - Fix minor issue in the ACPI system sleep support code and export
     one function from it (Lenny Szubowicz, Dexuan Cui).

   - Clean up assorted pieces of PM code and documentation (Kefeng Wang,
     Andy Shevchenko, Bart Van Assche, Greg Kroah-Hartman, Fuqian Huang,
     Geert Uytterhoeven, Mathieu Malaterre, Rafael Wysocki).

   - Update the pm-graph utility to v5.4 (Todd Brandt).

   - Fix and clean up the cpupower utility (Abhishek Goel, Nick Black)"

6b04014f3f IOMMU Updates for Linux v5.3 
Including:
 
 	- Patches to make the dma-iommu code more generic so that it can
 	  be used outside of the ARM context with other IOMMU drivers.
 	  Goal is to make use of it on x86 too.
 
 	- Generic IOMMU domain support for the Intel VT-d driver. This
 	  driver now makes more use of common IOMMU code to allocate
 	  default domains for the devices it handles.
 
 	- An IOMMU fault reporting API to userspace. With that the IOMMU
 	  fault handling can be done in user-space, for example to
 	  forward the faults to a VM.
 
 	- Better handling for reserved regions requested by the
 	  firmware. These can be 'relaxed' now, meaning that those don't
 	  prevent a device being attached to a VM.
 
 	- Suspend/Resume support for the Renesas IOMMU driver.
 
 	- Added support for dumping SVA related fields of the DMAR table
 	  in the Intel VT-d driver via debugfs.
 
 	- A pile of smaller fixes and cleanups.

Merge tag 'iommu-updates-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull iommu updates from Joerg Roedel:

 - Make the dma-iommu code more generic so that it can be used outside
   of the ARM context with other IOMMU drivers. Goal is to make use of
   it on x86 too.

 - Generic IOMMU domain support for the Intel VT-d driver. This driver
   now makes more use of common IOMMU code to allocate default domains
   for the devices it handles.

 - An IOMMU fault reporting API to userspace. With that the IOMMU fault
   handling can be done in user-space, for example to forward the faults
   to a VM.

 - Better handling for reserved regions requested by the firmware. These
   can be 'relaxed' now, meaning that those don't prevent a device being
   attached to a VM.

 - Suspend/Resume support for the Renesas IOMMU driver.

 - Added support for dumping SVA related fields of the DMAR table in the
   Intel VT-d driver via debugfs.

 - A pile of smaller fixes and cleanups.

c6b6cebbc5 spi: Updates for v5.3 
For the most part this is a quiet release for SPI, though there's
 several of the more widely used drivers that have had some fairly
 substantial development done on them, mainly improving
 performance and adding support for some more obscure use cases.
 
  - Support for configuring a minimum time for chip select to be
    deasserted between transfers from Martin Sperl.
  - A rework of the ACPI device instantiation code from Ard
    Biesheuvel.
  - Fairly substantial development on the AT91 USART, BCM2835 and
    Tegra114 drivers.
  - New driver for Socionext SynQuacer.

Core:
 
 - When a gpio_chip request GPIOs from itself, it can now fully
   control the line characteristics, both machine and consumer
   flags. This makes a lot of sense, but took some time before I
   figured out that this is how it has to work.

 New drivers:
 
 - The PCA953x driver now supports the TI TCA9539.
 
 - The DaVinci driver now supports the K3 AM654 SoCs.
 
 Driver improvements:
 
 - Major overhaul and hardening of the OMAP driver by Russell
   King.
 
 - Starting to move some drivers to the new API passing irq_chip
   along with the gpio_chip when adding the gpio_chip instead
   of adding it separately.
 
 Unrelated:

Merge tag 'gpio-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the big slew of GPIO changes for the v5.3 kernel cycle. This
  is mostly incremental work this time.

  Three important things:

   - The FMC subsystem is deleted through my tree. This happens through
     GPIO as its demise was discussed in relation to a patch decoupling
     its GPIO implementation from the standard way of handling GPIO. As
     it turns out, that is not the only subsystem it reimplements and
     the authors think it is better do scratch it and start over using
     the proper kernel subsystems than try to polish the rust shiny. See
     the commit (ACKed by the maintainers) for details.

   - Arnd made a small devres patch that was ACKed by Greg and goes into
     the device core.

   - SPDX header change colissions may happen, because at times I've
     seen that quite a lot changed during the -rc:s in regards to SPDX.
     (It is good stuff, tglx has me convinced, and it is worth the
     occasional pain.)

  Apart from this is is nothing controversial or problematic.

  Summary:

  Core:

   - When a gpio_chip request GPIOs from itself, it can now fully
     control the line characteristics, both machine and consumer flags.
     This makes a lot of sense, but took some time before I figured out

   - Allow references to thread objects after__machine_exit(), fixing a bug with
     'perf sched lat' where that happens, i.e. after perf_session__delete() we
     still have references to threads that were in a linked list whose head was
     freed in perf_session__delete(), causing a segfault, fix it.
 
   Jiri Olsa:
 
   - Do not rely on errno values for precise_ip fallback, fixing the default
     use case for 'perf record' on some AMD servers, when no events are specified
     and we try to use "cycles:P", i.e. with the maximum precision level.

5ad18b2e60 Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace 
Pull force_sig() argument change from Eric Biederman:
 "A source of error over the years has been that force_sig has taken a
  task parameter when it is only safe to use force_sig with the current
  task.

  The force_sig function is built for delivering synchronous signals
  such as SIGSEGV where the userspace application caused a synchronous
  fault (such as a page fault) and the kernel responded with a signal.

  Because the name force_sig does not make this clear, and because the
  force_sig takes a task parameter the function force_sig has been
  abused for sending other kinds of signals over the years. Slowly those
  have been fixed when the oopses have been tracked down.

  This set of changes fixes the remaining abusers of force_sig and
  carefully rips out the task parameter from force_sig and friends
  making this kind of error almost impossible in the future"

 "Bug fixes, code clean up, and new features:

   - IMA policy rules can be defined in terms of LSM labels, making the
     IMA policy dependent on LSM policy label changes, in particular LSM
     label deletions. The new environment, in which IMA-appraisal is
     being used, frequently updates the LSM policy and permits LSM label
     deletions.

   - Prevent an mmap'ed shared file opened for write from also being
     mmap'ed execute. In the long term, making this and other similar
     changes at the VFS layer would be preferable.

   - The IMA per policy rule template format support is needed for a
     couple of new/proposed features (eg. kexec boot command line
     measurement, appended signatures, and VFS provided file hashes).

   - Other than the "boot-aggregate" record in the IMA measuremeent
     list, all other measurements are of file data. Measuring and
     storing the kexec boot command line in the IMA measurement list is
     the first buffer based measurement included in the measurement
