        It would appear that the docutils developers, in their wisdom, broke
        the API in the 0.13 release. This fix detects the breakage and allows

      quota: Fix bogus warning in dquot_disable() · 2700e606
      Jan Kara authored
      dquot_disable() was warning when sb_has_quota_loaded() was true when
      invalidating page cache for quota files. The thinking behind this
      warning was that we must have raced with somebody else turning quotas on
      and this should not happen because all places modifying quota state must
      hold s_umount exclusively now. However sb_has_quota_loaded() can be also
      true at this point when we are just suspending quotas on remount
      read-only. Just restore the behavior to situation before commit
      c3b00446 ("quota: Remove dqonoff_mutex") which introduced the
      warning.
      
      The code in dquot_disable() can be further simplified with the new
      locking of quota state changes however let's leave that to a separate
      commit that can get more testing exposure.

      rtc: mcp795: fix month write resetting date to 1. · 43d0b10f
      Emil Bartczak authored
      According to Microchip errata some combinations of date and month
      values may result in the date being reset to 1, even if the date
      is also written with the month (for example 31-07 or 31-08).
      As a workaround avoid writing date and month values within the same
      Write command. Instead, terminate the Write command after loading
      the date and begin a new command to write the month. In addition,
      disable the oscillator before loading the new values. This is done
      by ensuring both the ST and EXTOSC bits are cleared and waiting for
      the OSCON bit to clear.

      Linus Torvalds authored
      Pull libnvdimm updates from Dan Williams:
       "The libnvdimm pull request is relatively small this time around due to
        some development topics being deferred to 4.11.
      
        As for this pull request the bulk of it has been in -next for several
        releases leading to one late fix being added (commit 868f036f
        ("libnvdimm: fix mishandled nvdimm_clear_poison() return value")). It
        has received a build success notification from the 0day-kbuild robot
        and passes the latest libnvdimm unit tests.
      
        Summary:
      
         - Dynamic label support: To date namespace label support has been
           limited to disambiguating cases where PMEM (direct load/store) and
           BLK (mmio aperture) accessed-capacity alias on the same DIMM. Since
           4.9 added support for multiple namespaces per PMEM-region there is
           value to support namespace labels even in the non-aliasing case.
           The presence of a valid namespace index block force-enables label
           support when the kernel would otherwise rely on region boundaries,
           and permits the region to be sub-divided.
      
         - Handle media errors in namespace metadata: Complement the error
           handling for media errors in namespace data areas with support for
           clearing errors on writes, and downgrading potential machine-check
           exceptions to simple i/o errors on read.
      
         - Device-DAX region attributes: Add 'align', 'id', and 'size' as
           attributes for device-dax regions. In particular this enables
           userspace tooling to generically size memory mapping and i/o
           operations. Prevent userspace from growing assumptions /
           dependencies about the parent device topology for a dax region. A
           libnvdimm namespace may not always be the parent device of a dax
           region.

      Pull timer updates from Thomas Gleixner:
       "This is the last functional update from the tip tree for 4.10. It got
        delayed due to a newly reported and anlyzed variant of BIOS bug and
        the resulting wreckage:
      
         - Seperation of TSC being marked realiable and the fact that the
           platform provides the TSC frequency via CPUID/MSRs and making use
           for it for GOLDMONT.
      
         - TSC adjust MSR validation and sanitizing:
      
           The TSC adjust MSR contains the offset to the hardware counter. The
           sum of the adjust MSR and the counter is the TSC value which is
           read via RDTSC.
      
           On at least two machines from different vendors the BIOS sets the
           TSC adjust MSR to negative values. This happens on cold and warm
           boot. While on cold boot the offset is a few milliseconds, on warm
           boot it basically compensates the power on time of the system. The
           BIOSes are not even using the adjust MSR to set all CPUs in the
           package to the same offset. The offsets are different which renders
           the TSC unusable,
      
           What's worse is that the TSC deadline timer has a HW feature^Wbug.
           It malfunctions when the TSC adjust value is negative or greater
           equal 0x80000000 resulting in silent boot failures, hard lockups or
           non firing timers. This looks like some hardware internal 32/64bit
           issue with a sign extension problem. Intel has been silent so far
           on the issue.
      
           The update contains sanity checks and keeps the adjust register
           within working limits and in sync on the package.
      
           As it looks like this disease is spreading via BIOS crapware, we
           need to address this urgently as the boot failures are hard to
           debug for users"

      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.
