       "Things are looking pretty quiet here in RDMA, not too many bug fixes
        rolling in right now. The usual driver bug fixes and fixes for a
        couple of regressions introduced in 5.2:
      
         - Fix a race on bootup with RDMA device renaming and srp. SRP also
           needs to rename its internal sys files
      
         - Fix a memory leak in hns
      
         - Don't leak resources in efa on certain error unwinds
      
         - Don't panic in certain error unwinds in ib_register_device
      
         - Various small user visible bug fix patches for the hfi and efa
           drivers
      
         - Fix the 32 bit compilation break"

      Pull ADFS cleanups/fixes from Russell King:
       "As a result of some of Al Viro's great work, here are a few cleanups
        with fixes for adfs:
      
         - factor out filename comparison, so we can be sure that
           adfs_compare() (used for namei compare) and adfs_match() (used for
           lookup) have the same behaviour.
      
         - factor out filename lowering (which is not the same as tolower()
           which will lower top-bit-set characters) to ensure that we have the
           same behaviour when comparing filenames as when we hash them.
      
         - factor out the object fixups, so we are applying all fixups to
           directory objects in the same way, independent of the disk format.
      
         - factor out the object name fixup (into the previously factored out
           function) to ensure that filenames are appropriately translated -
           for example, adfs allows '/' in filenames, which being the Unix
           path separator, need to be translated to a different character,
           which is normally '.' (DOS 8.3 filenames represent the . as a / on
           adfs, so this is the expected reverse translation.)
      
         - remove filename truncation; Al asked about this and apparently the
           decision is to remove it. In any case, adfs's truncation was buggy,
           so this rids us of that bug by removing the truncation feature.
      
         - we now have only one location which adds the "filetype" suffix to
           the filename, so there's no point that code being out of line.
      
         - since we translate '/' into '.', an adfs filename of "/" or "//"
           would end up being translated to "." and ".." which have special
           meanings. In this case, change the first character to "^" to avoid
           these special directory names being abused"

      arm64: Silence gcc warnings about arch ABI drift · ebcc5928
      Dave Martin authored
      Since GCC 9, the compiler warns about evolution of the
      platform-specific ABI, in particular relating for the marshaling of
      certain structures involving bitfields.
      
      The kernel is a standalone binary, and of course nobody would be
      so stupid as to expose structs containing bitfields as function
      arguments in ABI.  (Passing a pointer to such a struct, however
      inadvisable, should be unaffected by this change.  perf and various
      drivers rely on that.)
      
      So these warnings do more harm than good: turn them off.
      
      We may miss warnings about future ABI drift, but that's too bad.
      Future ABI breaks of this class will have to be debugged and fixed
      the traditional way unless the compiler evolves finer-grained
      diagnostics.

      parisc: Fix crash due alternative coding for NP iopdir_fdc bit · 527a1d1e
      Helge Deller authored
      According to the found documentation, data cache flushes and sync
      instructions are needed on the PCX-U+ (PA8200, e.g. C200/C240)
      platforms, while PCX-W (PA8500, e.g. C360) platforms aparently don't
      need those flushes when changing the IO PDIR data structures.
      
      We have no documentation for PCX-W+ (PA8600) and PCX-W2 (PA8700) CPUs,
      but Carlo Pisani reported that his C3600 machine (PA8600, PCX-W+) fails
      when the fdc instructions were removed. His firmware didn't set the NIOP
      bit, so one may assume it's a firmware bug since other C3750 machines
      had the bit set.
      
      Even if documentation (as mentioned above) states that PCX-W (PA8500,
      e.g.  J5000) does not need fdc flushes, Sven could show that an Adaptec
      29320A PCI-X SCSI controller reliably failed on a dd command during the
      first five minutes in his J5000 when fdc flushes were missing.
      
      Going forward, we will now NOT replace the fdc and sync assembler
      instructions by NOPS if:
      a) the NP iopdir_fdc bit was set by firmware, or
      b) we find a CPU up to and including a PCX-W+ (PA8600).
      
      This fixes the HPMC crashes on a C240 and C36XX machines. For other
      machines we rely on the firmware to set the bit when needed.
      
      In case one finds HPMC issues, people could try to boot their machines
      with the "no-alternatives" kernel option to turn off any alternative
      patching.

      parisc: Use lpa instruction to load physical addresses in driver code · 116d7533
      John David Anglin authored
      Most I/O in the kernel is done using the kernel offset mapping.
      However, there is one API that uses aliased kernel address ranges:
      
      > The final category of APIs is for I/O to deliberately aliased address
      > ranges inside the kernel.  Such aliases are set up by use of the
      > vmap/vmalloc API.  Since kernel I/O goes via physical pages, the I/O
      > subsystem assumes that the user mapping and kernel offset mapping are
      > the only aliases.  This isn't true for vmap aliases, so anything in
      > the kernel trying to do I/O to vmap areas must manually manage
      > coherency.  It must do this by flushing the vmap range before doing
      > I/O and invalidating it after the I/O returns.
      
      For this reason, we should use the hardware lpa instruction to load the
      physical address of kernel virtual addresses in the driver code.
      
      I believe we only use the vmap/vmalloc API with old PA 1.x processors
      which don't have a sba, so we don't hit this problem.

      We only support I/O to kernel space. Using %sr1 to load the coherence
