      Pull libata fixes from Tejun Heo:
       "There's one interseting commit - "libata, freezer: avoid block device
        removal while system is frozen".  It's an ugly hack working around a
        deadlock condition between driver core resume and block layer device
        removal paths through freezer which was made more reproducible by
        writeback being converted to workqueue some releases ago.  The bug has
        nothing to do with libata but it's just an workaround which is easy to
        backport.  After discussion, Rafael and I seem to agree that we don't
        really need kernel freezables - both kthread and workqueue.  There are
        few specific workqueues which constitute PM operations and require
        freezing, which will be converted to use workqueue_set_max_active()
        instead.  All other kernel freezer uses are planned to be removed,
        followed by the removal of kthread and workqueue freezer support,
        hopefully.
      
        Others are device-specific fixes.  The most notable is the addition of
        NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro
        M500 SSDs which otherwise suffers data corruption"

      aio: clean up and fix aio_setup_ring page mapping · 3dc9acb6
      Linus Torvalds authored
      Since commit 36bc08cc ("fs/aio: Add support to aio ring pages
      migration") the aio ring setup code has used a special per-ring backing
      inode for the page allocations, rather than just using random anonymous
      pages.
      
      However, rather than remembering the pages as it allocated them, it
      would allocate the pages, insert them into the file mapping (dirty, so
      that they couldn't be free'd), and then forget about them.  And then to
      look them up again, it would mmap the mapping, and then use
      "get_user_pages()" to get back an array of the pages we just created.
      
      Now, not only is that incredibly inefficient, it also leaked all the
      pages if the mmap failed (which could happen due to excessive number of
      mappings, for example).
      
      So clean it all up, making it much more straightforward.  Also remove
      some left-overs of the previous (broken) mm_populate() usage that was
      removed in commit d6c355c7 ("aio: fix race in ring buffer page
      lookup introduced by page migration support") but left the pointless and
      now misleading MAP_POPULATE flag around.

      intel_pstate driver, the desired default policy is not properly set. For
      example, setting 'CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE' ends up with the
      'powersave' policy being set.
      
      Fix by configuring the correct default policy, if either 'powersave' or
      'performance' are requested. Otherwise, fallback to what the driver originally
      set via its 'init' routine.

      cpufreq: remove sysfs files for CPUs which failed to come back after resume · 42f921a6
      Viresh Kumar authored
      There are cases where cpufreq_add_dev() may fail for some CPUs
      during system resume. With the current code we will still have
      sysfs cpufreq files for those CPUs and struct cpufreq_policy
      would be already freed for them. Hence any operation on those
      sysfs files would result in kernel warnings.
      
      Example of problems resulting from resume errors (from Bjørn Mork):
      
      WARNING: CPU: 0 PID: 6055 at fs/sysfs/file.c:343 sysfs_open_file+0x77/0x212()

      To fix this, remove those sysfs files or put the associated kobject
      in case of such errors. Also, to make it simple, remove the cpufreq
      sysfs links from all the CPUs (except for the policy->cpu) during
      suspend, as that operation won't result in a loss of sysfs file
      permissions and we can create those links during resume just fine.
      
      Fixes: 5302c3fb ("cpufreq: Perform light-weight init/teardown during suspend/resume")

      aio/migratepages: make aio migrate pages sane · 8e321fef
      Benjamin LaHaise authored
      The arbitrary restriction on page counts offered by the core
      migrate_page_move_mapping() code results in rather suspicious looking
      fiddling with page reference counts in the aio_migratepage() operation.
      To fix this, make migrate_page_move_mapping() take an extra_count parameter
      that allows aio to tell the code about its own reference count on the page
      being migrated.
      
      While cleaning up aio_migratepage(), make it validate that the old page
      being passed in is actually what aio_migratepage() expects to prevent
      misbehaviour in the case of races.

      null_blk: support submit_queues on use_per_node_hctx · fc1bc354
      Matias Bjørling authored
      In the case of both the submit_queues param and use_per_node_hctx param
      are used. We limit the number af submit_queues to the number of online
      nodes.
      
      If the submit_queues is a multiple of nr_online_nodes, its trivial. Simply map
      them to the nodes. For example: 8 submit queues are mapped as node0[0,1],
      node1[2,3], ...
      If uneven, we are left with an uneven number of submit_queues that must be
      mapped. These are mapped toward the first node and onward. E.g. 5
      submit queues mapped onto 4 nodes are mapped as node0[0,1], node1[2], ...

      The defaults for the module is to instantiate itself with blk-mq and a

      To save resources, initialize instead with a single submit queue.

      Don't set the INITRD_COMPRESS environment variable automatically · b7000ade
      Linus Torvalds authored
      Commit 1bf49dd4 ("./Makefile: export initial ramdisk compression
      config option") started setting the INITRD_COMPRESS environment variable
      depending on which decompression models the kernel had available.
      
      That is completely broken.
      
      For example, we by default have CONFIG_RD_LZ4 enabled, and are able to
      decompress such an initrd, but the user tools to *create* such an initrd
      may not be availble.  So trying to tell dracut to generate an
      lz4-compressed image just because we can decode such an image is
      completely inappropriate.
