      Pull clk updates from Stephen Boyd:
       "There are a few changes to the core framework this time around, in
        addition to the normal collection of driver updates to support new
        SoCs, fix incorrect data, and convert various drivers to clk_hw based
        APIs.
      
        In the core, we allow clk_ops::init() to return an error code now so
        that we can fail clk registration if the callback does something like
        fail to allocate memory. We also add a new "terminate" clk_op so that
        things done in clk_ops::init() can be undone, e.g. free memory. We
        also spit out a warning now when critical clks fail to enable and we
        support changing clk rates and enable/disable state through debugfs
        when developers compile the kernel themselves.
      
        On the driver front, we get support for what seems like a lot of
        Qualcomm and NXP SoCs given that those vendors dominate the diffstat.
        There are a couple new drivers for Xilinx and Amlogic SoCs too. The
        updates are all small things like fixing the way glitch free muxes
        switch parents, avoiding div-by-zero problems, or fixing data like
        parent names. See the updates section below for more details.
      
        Finally, the "basic" clk types have been converted to support
        specifying parents with clk_hw pointers. This work includes an
        overhaul of the fixed-rate clk type to be more modern by using clk_hw
        APIs.
      
        Core:
         - Let clk_ops::init() return an error code
         - Add a clk_ops::terminate() callback to undo clk_ops::init()
         - Warn about critical clks that fail to enable or prepare
         - Support dangerous debugfs actions on clks with dead code
      
        New Drivers:
         - Support for Xilinx Versal platform clks
         - Display clk controller on qcom sc7180
         - Video clk controller on qcom sc7180

      initramfs: do not show compression mode choice if INITRAMFS_SOURCE is empty · d4e9056d
      Masahiro Yamada authored
      Since commit ddd09bcc ("initramfs: make compression options not
      depend on INITRAMFS_SOURCE"), Kconfig asks the compression mode for
      the built-in initramfs regardless of INITRAMFS_SOURCE.
      
      It is technically simpler, but pointless from a UI perspective,
      Linus says [1].
      
      When INITRAMFS_SOURCE is empty, usr/Makefile creates a tiny default
      cpio, which is so small that nobody cares about the compression.
      
      This commit hides the Kconfig choice in that case. The default cpio
      is embedded without compression, which was the original behavior.

        In particular Douglas Anderson's modifications to the backtrace

        specific backtrace code and stop sharing certain data structures
        across the kernel. Note that The MIPS folks were on Cc: for the MIPS
        patch and reacted positively (but without an explicit Acked-by).
      
        Doug also got rid of the implicit switching between tasks and register
        sets during some but not of kdb's backtrace actions (because the
        implicit switching was either confusing for users, pointless or both).

      btrfs: do not zero f_bavail if we have available space · d55966c4
      Josef Bacik authored
      There was some logic added a while ago to clear out f_bavail in statfs()
      if we did not have enough free metadata space to satisfy our global
      reserve.  This was incorrect at the time, however didn't really pose a
      problem for normal file systems because we would often allocate chunks
      if we got this low on free metadata space, and thus wouldn't really hit
      this case unless we were actually full.
      
      Fast forward to today and now we are much better about not allocating
      metadata chunks all of the time.  Couple this with d792b0f1 ("btrfs:
      always reserve our entire size for the global reserve") which now means
      we'll easily have a larger global reserve than our free space, we are
      now more likely to trip over this while still having plenty of space.
      
      Fix this by skipping this logic if the global rsv's space_info is not
      full.  space_info->full is 0 unless we've attempted to allocate a chunk
      for that space_info and that has failed.  If this happens then the space
      for the global reserve is definitely sacred and we need to report
      b_avail == 0, but before then we can just use our calculated b_avail.

      vfs: fix do_last() regression · 6404674a
      Al Viro authored
      Brown paperbag time: fetching ->i_uid/->i_mode really should've been
      done from nd->inode.  I even suggested that, but the reason for that has
      slipped through the cracks and I went for dir->d_inode instead - made
      for more "obvious" patch.
      
      Analysis:
      
       - at the entry into do_last() and all the way to step_into(): dir (aka
         nd->path.dentry) is known not to have been freed; so's nd->inode and
         it's equal to dir->d_inode unless we are already doomed to -ECHILD.
         inode of the file to get opened is not known.
      
       - after step_into(): inode of the file to get opened is known; dir
         might be pointing to freed memory/be negative/etc.
      
       - at the call of may_create_in_sticky(): guaranteed to be out of RCU
         mode; inode of the file to get opened is known and pinned; dir might
         be garbage.
      
      The last was the reason for the original patch.  Except that at the
      do_last() entry we can be in RCU mode and it is possible that
      nd->path.dentry->d_inode has already changed under us.
      
      In that case we are going to fail with -ECHILD, but we need to be
      careful; nd->inode is pointing to valid struct inode and it's the same
      as nd->path.dentry->d_inode in "won't fail with -ECHILD" case, so we
      should use that.

       "A very quiet cycle with few notable changes. Mostly the usual list of
        one or two patches to drivers changing something that isn't quite rc
        worthy. The subsystem seems to be seeing a larger number of rework and
        cleanup style patches right now, I feel that several vendors are
        prepping their drivers for new silicon.
      
        Summary:
      
         - Driver updates and cleanup for qedr, bnxt_re, hns, siw, mlx5, mlx4,
           rxe, i40iw
      
         - Larger series doing cleanup and rework for hns and hfi1.
      
         - Some general reworking of the CM code to make it a little more
           understandable
      
         - Unify the different code paths connected to the uverbs FD scheme
      
         - New UAPI ioctls conversions for get context and get async fd
      
         - Trace points for CQ and CM portions of the RDMA stack
      
         - mlx5 driver support for virtio-net formatted rings as RDMA raw
           ethernet QPs
      
         - verbs support for setting the PCI-E relaxed ordering bit on DMA
           traffic connected to a MR
      
         - A couple of bug fixes that came too late to make rc7"

       - Fix some corner cases on filesystems with a block size < page size.
      
       - Fix a corner case that could expose incorrect access times over nfs.
      
       - Revert an otherwise sensible revoke accounting cleanup that causes
         assertion failures. The revoke accounting is whacky and needs to be
         fixed properly before we can add back this cleanup.
      
       - Various other minor cleanups.
      
      In addition, please expect to see another pull request from Bob Peterson
      about his gfs2 recovery patch queue shortly.

      Pull module updates from Jessica Yu:
       "Summary of modules changes for the 5.6 merge window:
      
         - Add "MS" (SHF_MERGE|SHF_STRINGS) section flags to __ksymtab_strings
           to indicate to the linker that it can perform string deduplication
           (i.e., duplicate strings are reduced to a single copy in the string
           table). This means any repeated namespace string would be merged to
           just one entry in __ksymtab_strings.
      
         - Various code cleanups and small fixes (fix small memleak in error
           path, improve moduleparam docs, silence rcu warnings, improve error
           logging)"

        modsign: print module name along with error message
        kernel/module: Fix memleak in module_add_modinfo_attrs()
        export.h: reduce __ksymtab_strings string duplication by using "MS" section flags
