      Pull libata ZAC support from Tejun Heo:
       "This contains Zone ATA Command support for Shingled Magnetic Recording
        devices.
      
        In addition to sending the new commands down to the device, as ZAC
        commands depend on getting a lot of responses from the device, piping
        up responses is beefed up too.  However, it doesn't involve changes to
        libata core mechanism or its interaction with upper layers, so I'm not
        expecting too many fallouts.

      Linus Torvalds authored
      Pull libnvdimm updates from Dan Williams:
       "The bulk of this update was stabilized before the merge window and
        appeared in -next.  The "device dax" implementation was revised this
        week in response to review feedback, and to address failures detected
        by the recently expanded ndctl unit test suite.
      
        Not included in this pull request are two dax topic branches (dax
        error handling, and dax radix-tree locking).  These topics were
        deferred to get a few more days of -next integration testing, and to
        coordinate a branch baseline with Ted and the ext4 tree.  Vishal and
        Ross will send the error handling and locking topics respectively in
        the next few days.
      
        This branch has received a positive build result from the kbuild robot
        across 226 configs.
      
        Summary:
      
         - Device DAX for persistent memory: Device DAX is the device-centric
           analogue of Filesystem DAX (CONFIG_FS_DAX).  It allows memory
           ranges to be allocated and mapped without need of an intervening
           file system.  Device DAX is strict, precise and predictable.
           Specifically this interface:
      
            a) Guarantees fault granularity with respect to a given page size
               (pte, pmd, or pud) set at configuration time.
      
            b) Enforces deterministic behavior by being strict about what
               fault scenarios are supported.
      
           Persistent memory is the first target, but the mechanism is also
           targeted for exclusive allocations of performance/feature
           differentiated memory ranges.
      
         - Support for the HPE DSM (device specific method) command formats.
           This enables management of these first generation devices until a
           unified DSM specification materializes.
      
         - Further ACPI 6.1 compliance with support for the common dimm
           identifier format.
      
         - Various fixes and cleanups across the subsystem"

       "Three more changes.
      
         - I forgot that I had another selftest to stress test the ftrace
           instance creation.  It was actually suppose to go into the 4.6
           merge window, but I never committed it.  I almost forgot about it
           again, but noticed it was missing from your tree.
      
         - Soumya PN sent me a clean up patch to not disable interrupts when
           taking the tasklist_lock for read, as it's unnecessary because that
           lock is never taken for write in irq context.
      
         - Newer gcc's can cause the jump in the function_graph code to the
           global ftrace_stub label to be a short jump instead of a long one.
           As that jump is dynamically converted to jump to the trace code to
           do function graph tracing, and that conversion expects a long jump
           it can corrupt the ftrace_stub itself (it's directly after that
           call).  One way to prevent gcc from using a short jump is to
           declare the ftrace_stub as a weak function, which we do here to
           keep gcc from optimizing too much"

      x86: remove more uaccess_32.h complexity · bd28b145

      I'm looking at trying to possibly merge the 32-bit and 64-bit versions

      For example, the 32-bit version of "__copy_from_user_inatomic()" is
      mostly the special cases for the constant size, and it's actually almost
      never relevant.  Most users aren't actually using a constant size
      anyway, and the few cases that do small constant copies are better off
      just using __get_user() instead.

      x86: remove pointless uaccess_32.h complexity · 5b09c3ed
      Linus Torvalds authored
      I'm looking at trying to possibly merge the 32-bit and 64-bit versions
      of the x86 uaccess.h implementation, but first this needs to be cleaned
      up.
      
      For example, the 32-bit version of "__copy_to_user_inatomic()" is mostly
      the special cases for the constant size, and it's actually never
      relevant.  Every user except for one aren't actually using a constant
      size anyway, and the one user that uses it is better off just using
      __put_user() instead.
      
      So get rid of the unnecessary complexity.
      
      [ The same cleanup should likely happen to __copy_from_user_inatomic()
        as well, but that one has a lot more users that I need to take a look
        at first ]

       "In this round, as Ted pointed out, fscrypto allows one more key prefix
        given by filesystem to resolve backward compatibility issues.  Other
        than that, we've fixed several error handling cases by introducing
        a fault injection facility.  We've also achieved performance
        improvement in some workloads as well as a bunch of bug fixes.
      
        Summary:
      
        Enhancements:
         - fs-specific prefix for fscrypto
         - fault injection facility
         - expose validity bitmaps for user to be aware of fragmentation
         - fallocate/rm/preallocation speed up

      libnvdimm, dax: fix alignment validation · 5e24c9fd
      Dan Williams authored
      Testing the dax-device autodetect support revealed a probe failure with
      the following result:
      
          dax0.1: bad offset: 0x8200000 dax disabled
      
      The original pfn-device implementation inferred the alignment from
      ilog2(offset), now that the alignment is explicit the is_power_of_2()
      needs replacing with a real sanity check against the recorded alignment.
      Otherwise the alignment check is useless in the implicit case and only
      the minimum size of the offset matters.
      
      This self-consistency check is further validated by the probe path that
      will re-check that the offset is large enough to contain all the
      metadata required to enable the device.

      x86 isa: add back X86_32 dependency on CONFIG_ISA · 51e68d05
      Linus Torvalds authored
      Commit b3c1be1b ("base: isa: Remove X86_32 dependency") made ISA
      support available on x86-64 too.  That's not right - while there are
      some LPC-style devices that might be useful still and be based on
      ISA-like IP blocks, that is *not* an excuse to try to enable any random
      legacy drivers.
      
      Such drivers should be individually enabled and made to perhaps depend
      on ISA_DMA_API instead (which we have continued to support on x86-64).
      Or we could add another "ISA_XYZ_API" that we support that doesn't
      enable random old drivers that aren't even 64-bit clean nor do we have
      any test coverage for.
      
      Turning off ISA will now also turn off some drivers that have been
      marked as depending on it as part of this series, and that used to work
      on modern platforms.
      
      See for example commits ad7afc38..cc736607, which may also need
      to be reverted.
      
      This commit means that the warnings that came in due to enabling ISA
      widely are now gone again.

      These alarms can be enabled or disabled individually using an AE_x bit
      which is the last bit (BIT(7)) on each alarm registers.
      
      To prepare the alarm IRQ support, the current code enables all the alarm
      types by setting each AE_x to 1.
      It also fixes others alarms issues :
         - month and weekday errors : it was performing -1 instead of +1.

        Other than that, just a lot of basic coding style cleanups in the
        churn.  All have been in linux-next for a while with no reported
        issues"

      libnvdimm, dax: autodetect support · c5ed9268
      Dan Williams authored
      For autodetecting a previously established dax configuration we need the
      info block to indicate block-device vs device-dax mode, and we need to
      have the default namespace probe hand-off the configuration to the
      dax_pmem driver.
