      Pull ARM SoC defconfig updates from Olof Johansson:
       "We keep this in a separate branch to avoid cross-branch conflicts, but
        most of the material here is fairly boring -- some new drivers turned
        on for hardware since they were merged, and some refreshed files due
        to time having moved a lot of entries around"

      Pull ARM SoC platform updates from Olof Johansson:
       "SoC changes, a substantial part of this is cleanup of some of the
        older platforms that used to have a bunch of board files.
      
        In particular:
      
         - Remove non-DT i.MX platforms that haven't seen activity in years,
           it's time to remove them.
      
         - A bunch of cleanup and removal of platform data for TI/OMAP
           platforms, moving over to genpd for power/reset control (yay!)
      
         - Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
           closer to multiplatform support (not quite there yet, but getting
           close).
      
        There are a few other changes too, smaller fixlets, etc. For new
        platform support, the primary ones are:
      
         - New SoC: Hisilicon SD5203, ARM926EJ-S platform.
      
         - Cpufreq support for i.MX7ULP"

      Pull more power management updates from Rafael Wysocki:
       "First of all, the adaptive voltage scaling (AVS) drivers go to new
        platform-specific locations as planned (this part was reported to have
        merge conflicts against the new arm-soc updates in linux-next).
      
        In addition to that, there are some fixes (intel_idle, intel_pstate,
        RAPL, acpi_cpufreq), the addition of on/off notifiers and idle state
        accounting support to the generic power domains (genpd) code and some
        janitorial changes all over.
      
        Specifics:
      
         - Move the AVS drivers to new platform-specific locations and get rid
           of the drivers/power/avs directory (Ulf Hansson).
      
         - Add on/off notifiers and idle state accounting support to the
           generic power domains (genpd) framework (Ulf Hansson, Lina Iyer).
      
         - Ulf will maintain the PM domain part of cpuidle-psci (Ulf Hansson).
      
         - Make intel_idle disregard ACPI _CST if it cannot use the data
           returned by that method (Mel Gorman).
      
         - Modify intel_pstate to avoid leaving useless sysfs directory
           structure behind if it cannot be registered (Chen Yu).
      
         - Fix domain detection in the RAPL power capping driver and prevent
           it from failing to enumerate the Psys RAPL domain (Zhang Rui).
      
         - Allow acpi-cpufreq to use ACPI _PSD information with Family 19 and
           later AMD chips (Wei Huang).
      
         - Update the driver assumptions comment in intel_idle and fix a
           kerneldoc comment in the runtime PM framework (Alexander Monakov,
           Bean Huo).
      
         - Avoid unnecessary resets of the cached frequency in the schedutil
           cpufreq governor to reduce overhead (Wei Wang).
      
         - Clean up the cpufreq core a bit (Viresh Kumar).
      
         - Make assorted minor janitorial changes (Daniel Lezcano, Geert
           Uytterhoeven, Hubert Jasudowicz, Tom Rix).

        got held over from the initial merge window pull request to give more
        testing time, which they've now had and Syzbot has confirmed the

      x86/uaccess: fix code generation in put_user() · 9c5743df
      Rasmus Villemoes authored
      Quoting https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html:
      
        You can define a local register variable and associate it with a
        specified register...
      
        The only supported use for this feature is to specify registers for
        input and output operands when calling Extended asm (see Extended
        Asm). This may be necessary if the constraints for a particular
        machine don't provide sufficient control to select the desired
        register.
      
      On 32-bit x86, this is used to ensure that gcc will put an 8-byte value
      into the %edx:%eax pair, while all other cases will just use the single
      register %eax (%rax on x86-64).  While the _ASM_AX actually just expands
      to "%eax", note this comment next to get_user() which does something
      very similar:
      
       * The use of _ASM_DX as the register specifier is a bit of a
       * simplification, as gcc only cares about it as the starting point
       * and not size: for a 64-bit value it will use %ecx:%edx on 32 bits
       * (%ecx being the next register in gcc's x86 register sequence), and
       * %rdx on 64 bits.
      
      However, getting this to work requires that there is no code between the
      assignment to the local register variable and its use as an input to the
      asm() which can possibly clobber any of the registers involved -
      including evaluation of the expressions making up other inputs.
      
      In the current code, the ptr expression used directly as an input may
      cause such code to be emitted.  For example, Sean Christopherson
      observed that with KASAN enabled and ptr being current->set_child_tid
      (from chedule_tail()), the load of current->set_child_tid causes a call
      to __asan_load8() to be emitted immediately prior to the __put_user_4
      call, and Naresh Kamboju reports that various mmstress tests fail on
      KASAN-enabled builds.
      
      It's also possible to synthesize a broken case without KASAN if one uses
      "foo()" as the ptr argument, with foo being some "extern u64 __user
      *foo(void);" (though I don't know if that appears in real code).
      
      Fix it by making sure ptr gets evaluated before the assignment to
      __val_pu, and add a comment that __val_pu must be the last thing
      computed before the asm() is entered.

           which changed with the 5.10 PR from the usb subsystem

           and only wants to schedule napi (and do so through a _irqoff()

           tunnels
      
         - fix various issues in chelsio inline tls driver

      gfs2: Recover statfs info in journal head · bedb0f05
      Abhi Das authored
      Apply the outstanding statfs changes in the journal head to the
      master statfs file. Zero out the local statfs file for good measure.
      
      Previously, statfs updates would be read in from the local statfs inode and
      synced to the master statfs inode during recovery.
      
      We now use the statfs updates in the journal head to update the master statfs
      inode instead of reading in from the local statfs inode. To preserve backward
      compatibility with kernels that can't do this, we still need to keep the
      local statfs inode up to date by writing changes to it. At some point in the
      future, we can do away with the local statfs inodes altogether and keep the
      statfs changes solely in the journal.

      kvm: x86/mmu: NX largepage recovery for TDP MMU · 29cf0f50
      Ben Gardon authored
      When KVM maps a largepage backed region at a lower level in order to
      make it executable (i.e. NX large page shattering), it reduces the TLB
      performance of that region. In order to avoid making this degradation
      permanent, KVM must periodically reclaim shattered NX largepages by
      zapping them and allowing them to be rebuilt in the page fault handler.
      
      With this patch, the TDP MMU does not respect KVM's rate limiting on
      reclaim. It traverses the entire TDP structure every time. This will be
      addressed in a future patch.
      
      Tested by running kvm-unit-tests and KVM selftests on an Intel Haswell
      machine. This series introduced no new failures.

      kvm: x86/mmu: Support disabling dirty logging for the tdp MMU · 14881998
      Ben Gardon authored
      Dirty logging ultimately breaks down MMU mappings to 4k granularity.
      When dirty logging is no longer needed, these granaular mappings
      represent a useless performance penalty. When dirty logging is disabled,
      search the paging structure for mappings that could be re-constituted
      into a large page mapping. Zap those mappings so that they can be
      faulted in again at a higher mapping level.

      kvm: x86/mmu: Add access tracking for tdp_mmu · f8e14497
      Ben Gardon authored
      In order to interoperate correctly with the rest of KVM and other Linux
      subsystems, the TDP MMU must correctly handle various MMU notifiers. The
      main Linux MM uses the access tracking MMU notifiers for swap and other
      features. Add hooks to handle the test/flush HVA (range) family of
      MMU notifiers.
      
      Tested by running kvm-unit-tests and KVM selftests on an Intel Haswell
      machine. This series introduced no new failures.
