      Pull ARM spectre updates from Russell King:
       "These are the currently known final bits that resolve the Spectre
        issues. big.Little systems used to be sufficiently identical in that
        there were no differences between individual CPUs in the system that
        mattered to the kernel. With the advent of the Spectre problem, the
        CPUs now have differences in how the workaround is applied.
      
        As a result of previous Spectre patches, these systems ended up
        reporting quite a lot of:
      
           "CPUx: Spectre v2: incorrect context switching function, system vulnerable"
      
        messages due to the action of the big.Little switcher causing the CPUs
        to be re-initialised regularly. This series resolves that issue by
        making the CPU vtable unique to each CPU.
      
        However, since this is used very early, before per-cpu is setup,
        per-cpu can't be used. We also have a problem that two of the methods
        are not called from preempt-safe paths, but thankfully these remain
        identical between all CPUs in the system. To make sure, we validate
        that these are identical during boot"

        ARM: spectre-v2: per-CPU vtables to work around big.Little systems

      gfs2: Fix iomap buffer head reference counting bug · c26b5aa8
      Andreas Gruenbacher authored
      GFS2 passes the inode buffer head (dibh) from gfs2_iomap_begin to
      gfs2_iomap_end in iomap->private.  It sets that private pointer in
      gfs2_iomap_get.  Users of gfs2_iomap_get other than gfs2_iomap_begin
      would have to release iomap->private, but this isn't done correctly,
      leading to a leak of buffer head references.
      
      To fix this, move the code for setting iomap->private from
      gfs2_iomap_get to gfs2_iomap_begin.

       "Two weeks worth of fixes since rc1.
      
         - I broke 16-byte alignment of the stack when we moved PPR into
           pt_regs. Despite being required by the ABI this broke almost
           nothing, we eventually hit it in code where GCC does arithmetic on
           the stack pointer assuming the bottom 4 bits are clear. Fix it by
           padding the in-kernel pt_regs by 8 bytes.
      
         - A couple of commits fixing minor bugs in the recent SLB rewrite.
      
         - A build fix related to tracepoints in KVM in some configurations.
      
         - Our old "IO workarounds" code written for Cell couldn't coexist in
           a kernel that runs on Power9 with the Radix MMU, fix that.
      
         - Remove the NPU DMA ops, these just printed a warning and should
           never have been called.
      
         - Suppress an overly chatty message triggered by CPU hotplug in some
           configs.
