       "Bug fixes for main IPMI driver, kcs updates
      
        A couple of bug fixes for the main IPMI driver, one functional and two
        annotations.
      
        The kcs driver has some significant updates that have been pending for
        a while, but I forgot to include in next until a week ago. But this
        code is only used by the people who are sending it to me, really, so
        it's not a big deal. I did want it to sit in next for at least a week,
        and it did result in a fix"

      Pull more xfs updates from Darrick Wong:
       "As promised last week, this batch changes how xfs interacts with
        memory reclaim; how the log batches and throttles log items; how hard
        writes near ENOSPC will try to squeeze more space out of the
        filesystem; and hopefully fix the last of the umount hangs after a
        catastrophic failure.
      
        Summary:
      
         - Validate the realtime geometry in the superblock when mounting
      
         - Refactor a bunch of tricky flag handling in the log code
      
         - Flush the CIL more judiciously so that we don't wait until there
           are millions of log items consuming a lot of memory.
      
         - Throttle transaction commits to prevent the xfs frontend from
           flooding the CIL with too many log items.
      
         - Account metadata buffers correctly for memory reclaim.
      
         - Mark slabs properly for memory reclaim. These should help reclaim
           run more effectively when XFS is using a lot of memory.
      
         - Don't write a garbage log record at unmount time if we're trying to
           trigger summary counter recalculation at next mount.
      
         - Don't block the AIL on locked dquot/inode buffers; instead trigger
           its backoff mechanism to give the lock holder a chance to finish
           up.
      
         - Ratelimit writeback flushing when buffered writes encounter ENOSPC.
      
         - Other minor cleanups.
      
         - Make reflink a synchronous operation when the fs is mounted with
           wsync or sync, which means that now we force the log to disk to
           record the changes"

      io_uring: punt final io_ring_ctx wait-and-free to workqueue · 85faa7b8
      Jens Axboe authored
      We can't reliably wait in io_ring_ctx_wait_and_kill(), since the
      task_works list isn't ordered (in fact it's LIFO ordered). We could
      either fix this with a separate task_works list for io_uring work, or
      just punt the wait-and-free to async context. This ensures that
      task_work that comes in while we're shutting down is processed
      correctly. If we don't go async, we could have work past the fput()
      work for the ring that depends on work that won't be executed until
      after we're done with the wait-and-free. But as this operation is
      blocking, it'll never get a chance to run.
      
      This was reproduced with hundreds of thousands of sockets running
      memcached, haven't been able to reproduce this synthetically.

      Until we've figured out what other TTM drivers do differently compared to
      vmwgfx, disable the huge_fault() callback, eliminating transhuge

      drm/bridge: analogix_dp: Split bind() into probe() and real bind() · 152cce00
      Marek Szyprowski authored
      Analogix_dp driver acquires all its resources in the ->bind() callback,
      what is a bit against the component driver based approach, where the
      driver initialization is split into a probe(), where all resources are
      gathered, and a bind(), where all objects are created and a compound
      driver is initialized.
      
      Extract all the resource related operations to analogix_dp_probe() and
      analogix_dp_remove(), then call them before/after registration of the
      device components from the main Exynos DP and Rockchip DP drivers. Also
      move the plat_data initialization to the probe() to make it available for
      the analogix_dp_probe() function.
      
      This fixes the multiple calls to the bind() of the DRM compound driver
      when the DP PHY driver is not yet loaded/probed:

           When the driver was converted to blk-mq, we settled on a single

      Merge tag 'libnvdimm-for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm · 9b06860d
      Linus Torvalds authored
      Pull libnvdimm and dax updates from Dan Williams:
       "There were multiple touches outside of drivers/nvdimm/ this round to
        add cross arch compatibility to the devm_memremap_pages() interface,
        enhance numa information for persistent memory ranges, and add a
        zero_page_range() dax operation.
      
        This cycle I switched from the patchwork api to Konstantin's b4 script
        for collecting tags (from x86, PowerPC, filesystem, and device-mapper
        folks), and everything looks to have gone ok there. This has all
        appeared in -next with no reported issues.
      
        Summary:
      
         - Add support for region alignment configuration and enforcement to
           fix compatibility across architectures and PowerPC page size
           configurations.
      
         - Introduce 'zero_page_range' as a dax operation. This facilitates
           filesystem-dax operation without a block-device.
      
         - Introduce phys_to_target_node() to facilitate drivers that want to
           know resulting numa node if a given reserved address range was
           onlined.
      
         - Advertise a persistence-domain for of_pmem and papr_scm. The
           persistence domain indicates where cpu-store cycles need to reach
           in the platform-memory subsystem before the platform will consider
           them power-fail protected.
      
         - Promote numa_map_to_online_node() to a cross-kernel generic
           facility.
      
         - Save x86 numa information to allow for node-id lookups for reserved
           memory ranges, deploy that capability for the e820-pmem driver.
      
         - Pick up some miscellaneous minor fixes, that missed v5.6-final,
           including a some smatch reports in the ioctl path and some unit
           test compilation fixups.
      
         - Fixup some flexible-array declarations"
