      struct clocksource is also used by the clk notifier callback, to
      unregister and re-register the clocksource with a different clock rate.
      clocksource_mmio_init does not pass back a pointer to the struct used,
      and the clk notifier callback assumes that the struct clocksource in
      struct sun5i_timer_clksrc is valid. This results in a kernel NULL

      A malicious user space can provide an invalid mode for runtime

      the target host during migration. This would trigger a WARN_ON

      clocksource: Add J-Core timer/clocksource driver · 9995f4f1
      Rich Felker authored
      At the hardware level, the J-Core PIT is integrated with the interrupt
      controller, but it is represented as its own device and has an
      independent programming interface. It provides a 12-bit countdown
      timer, which is not presently used, and a periodic timer. The interval
      length for the latter is programmable via a 32-bit throttle register
      whose units are determined by a bus-period register. The periodic
      timer is used to implement both periodic and oneshot clock event
      modes; in oneshot mode the interrupt handler simply disables the timer
      as soon as it fires.
      
      Despite its device tree node representing an interrupt for the PIT,
      the actual irq generated is programmable, not hard-wired. The driver
      is responsible for programming the PIT to generate the hardware irq
      number that the DT assigns to it.
      
      On SMP configurations, J-Core provides cpu-local instances of the PIT;
      no broadcast timer is needed. This driver supports the creation of the
      necessary per-cpu clock_event_device instances.
      
      A nanosecond-resolution clocksource is provided using the J-Core "RTC"
      registers, which give a 64-bit seconds count and 32-bit nanoseconds
      that wrap every second. The driver converts these to a full-range
      32-bit nanoseconds count.

      KVM: s390: reject invalid modes for runtime instrumentation · a5efb6b6
      Christian Borntraeger authored
      Usually a validity intercept is a programming error of the host
      because of invalid entries in the state description.
      We can get a validity intercept if the mode of the runtime
      instrumentation control block is wrong. As the host does not know
      which modes are valid, this can be used by userspace to trigger
      a WARN.
      Instead of printing a WARN let's return an error to userspace as
      this can only happen if userspace provides a malformed initial
      value (e.g. on migration). The kernel should never warn on bogus
      input. Instead let's log it into the s390 debug feature.
      
      While at it, let's return -EINVAL for all validity intercepts as
      this will trigger an error in QEMU like
      
      error: kvm run failed Invalid argument
      PSW=mask 0404c00180000000 addr 000000000063c226 cc 00

       "Most of these are CC'd for stable, but there are a few fixing issues
        introduced during the recent merge window too.
      
        There's also a fix for the xgene PMU driver, but it seemed daft to
        send as a separate pull request, so I've included it here with the
        rest of the fixes.
      
         - Fix ACPI boot due to recent broken NUMA changes
         - Fix remote enabling of CPU features requiring PSTATE bit manipulation
         - Add address range check when emulating user cache maintenance
         - Fix LL/SC loops that allow compiler to introduce memory accesses
         - Fix recently added write_sysreg_s macro
         - Ensure MDCR_EL2 is initialised on qemu targets without a PMU
         - Avoid kaslr breakage due to MODVERSIONs and DYNAMIC_FTRACE
         - Correctly drive recent ld when building relocatable Image
         - Remove junk IS_ERR check from xgene PMU driver added during merge window
         - pr_cont fixes after core changes in the merge window"

      Pull MMC fixes from Ulf Hansson:
       "Here are some mmc fixes intended for v4.9 rc2.
      
        This time I have also included a few changes for a memstick driver
        which has a corresponding mmc driver. They use the same USB device as
        parent, hence both needs to play nice with runtime PM, which they
        didn't.
      
        MMC core:
         - Update MAINTAINERS as the mmc tree moved to kernel.org
         - A few fixes for HS400es mode
         - A few other minor fixes
      
        MMC host:
         - sdhci: Fix an issue when dealing with stop commands
         - sdhci-pci: Fix a bus power failure issue
         - sdhci-esdhc-imx: Correct two register accesses
         - sdhci-of-arasan: Fix the 1.8V I/O signal switch behaviour

      cpufreq: fix overflow in cpufreq_table_find_index_dl() · c6fe46a7
      Sergey Senozhatsky authored
      'best' is always less or equals to 'pos', so `best - pos' returns
      a negative value which is then getting casted to `unsigned int'
      and passed to __cpufreq_driver_target()->acpi_cpufreq_target()
      for policy->freq_table selection. This results in
