      x86/tsc: Limit the adjust value further · 8c9b9d87
      Thomas Gleixner authored
      Adjust value 0x80000000 and other values larger than that render the TSC
      deadline timer disfunctional.
      
      We have not yet any information about this from Intel, but experimentation
      clearly proves that this is a 32/64 bit and sign extension issue.
      
      If adjust values larger than that are actually required, which might be the
      case for physical CPU hotplug, then we need to disable the deadline timer
      on the affected package/CPUs and use the local APIC timer instead.
      
      That requires some surgery in the APIC setup code, so we just limit the
      ADJUST register value into the known to work range for now and revisit this
      when Intel comes forth with proper information.

      x86/tsc: Force TSC_ADJUST register to value >= zero · 5bae1562
      Thomas Gleixner authored
      Roland reported that his DELL T5810 sports a value add BIOS which
      completely wreckages the TSC. The squirmware [(TM) Ingo Molnar] boots with
      random negative TSC_ADJUST values, different on all CPUs. That renders the
      TSC useless because the sycnchronization check fails.
      
      Roland tested the new TSC_ADJUST mechanism. While it manages to readjust
      the TSCs he needs to disable the TSC deadline timer, otherwise the machine
      just stops booting.
      
      Deeper investigation unearthed that the TSC deadline timer is sensitive to
      the TSC_ADJUST value. Writing TSC_ADJUST to a negative value results in an
      interrupt storm caused by the TSC deadline timer.
      
      This does not make any sense and it's hard to imagine what kind of hardware
      wreckage is behind that misfeature, but it's reliably reproducible on other
      systems which have TSC_ADJUST and TSC deadline timer.
      
      While it would be understandable that a big enough negative value which
      moves the resulting TSC readout into the negative space could have the
      described effect, this happens even with a adjust value of -1, which keeps
      the TSC readout definitely in the positive space. The compare register for
      the TSC deadline timer is set to a positive value larger than the TSC, but
      despite not having reached the deadline the interrupt is raised
      immediately. If this happens on the boot CPU, then the machine dies
      silently because this setup happens before the NMI watchdog is armed.
      
      Further experiments showed that any other adjustment of TSC_ADJUST works as
      expected as long as it stays in the positive range. The direction of the
      adjustment has no influence either. See the lkml link for further analysis.
      
      Yet another proof for the theory that timers are designed by janitors and
      the underlying (obviously undocumented) mechanisms which allow BIOSes to
      wreckage them are considered a feature. Well done Intel - NOT!
      
      To address this wreckage add the following sanity measures:
      
      - If the TSC_ADJUST value on the boot cpu is not 0, set it to 0
      
      - If the TSC_ADJUST value on any cpu is negative, set it to 0
      
      - Prevent the cross package synchronization mechanism from setting negative
        TSC_ADJUST values.

      x86/tsc: Validate TSC_ADJUST after resume · 6a369583
      Thomas Gleixner authored
      Some 'feature' BIOSes fiddle with the TSC_ADJUST register during
      suspend/resume which renders the TSC unusable.
      
      Add sanity checks into the resume path and restore the
      original value if it was adjusted.

      iio: maxim_thermocouple: detect invalid storage size in read() · d70674ee
      Arnd Bergmann authored
      As found by gcc -Wmaybe-uninitialized, having a storage_bytes value other
      than 2 or 4 will result in undefined behavior:
      
      drivers/iio/temperature/maxim_thermocouple.c: In function 'maxim_thermocouple_read':
      drivers/iio/temperature/maxim_thermocouple.c:141:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
      
      This probably cannot happen, but returning -EINVAL here is appropriate
      and makes gcc happy and the code more robust.

      aoe: fix crash in page count manipulation · 0cbc72a1
      Jens Axboe authored
      aoeblk contains some mysterious code, that wants to elevate the bio
      vec page counts while it's under IO. That is not needed, it's
      fragile, and it's causing kernel oopses for some.

      lightnvm: invalid offset calculation for lba_shift · 409ae5a7
      Matias Bjørling authored
      The ns->lba_shift assumes its value to be the logarithmic of the
      LA size. A previous patch duplicated the lba_shift calculation into
      lightnvm. It prematurely also subtracted a 512byte shift, which commonly
      is applied per-command. The 512byte shift being subtracted twice led to
      data loss when restoring the logical to physical mapping table from
      device and when issuing I/O commands using rrpc.
      
      Fix offset by removing the 512byte shift subtraction when calculating
      lba_shift.

      Pull power management fixes from Rafael Wysocki:
       "These fix two bugs in error code paths in the PM core (system-wide

        Specifics:
      
         - Prevent the PM core from attempting to suspend parent devices if
           any of their children, whose suspend callbacks were invoked
           asynchronously, have failed to suspend during the "late" and
           "noirq" phases of system-wide suspend of devices (Brian Norris).
      
         - Prevent the boot-time system suspend test code from leaking a
           reference to the RTC device used by it (Johan Hovold).
      
         - Fix cpupower to use the return value of one of its library
           functions correctly and restore the correct behavior of it when
           used for setting cpufreq tunables broken during the 4.7 development
