      Pull more xfs updates from Darrick Wong:
       "As promised, here's a (much smaller) second pull request for the
        second week of the merge cycle. This time around we have a couple
        patches shutting off unsupported fs configurations, and a couple of
        cleanups.
      
        Last, we turn off EXPERIMENTAL for the reverse mapping btree, since
        the primary downstream user of that information (online fsck) is now
        upstream and I haven't seen any major failures in a few kernel
        releases.
      
        Summary:
      
         - Print scrub build status in the xfs build info.
      
         - Explicitly call out the remaining two scenarios where we don't
           support reflink and never have.
      
         - Remove EXPERIMENTAL tag from reverse mapping btree!"

      Pull overlayfs updates from Miklos Szeredi:
       "This work from Amir adds NFS export capability to overlayfs. NFS
        exporting an overlay filesystem is a challange because we want to keep
        track of any copy-up of a file or directory between encoding the file
        handle and decoding it.
      
        This is achieved by indexing copied up objects by lower layer file
        handle. The index is already used for hard links, this patchset
        extends the use to NFS file handle decoding"

      ovl: fix regression in fsnotify of overlay merge dir · 2aed489d
      Amir Goldstein authored
      A re-factoring patch in NFS export series has passed the wrong argument
      to ovl_get_inode() causing a regression in the very recent fix to
      fsnotify of overlay merge dir.
      
      The regression has caused merge directory inodes to be hashed by upper
      instead of lower real inode, when NFS export and directory indexing is
      disabled. That caused an inotify watch to become obsolete after directory
      copy up and drop caches.
      
      LTP test inotify07 was improved to catch this regression.
      The regression also caused multiple redirect dirs to same origin not to
      be detected on lookup with NFS export disabled. An xfstest was added to
      cover this case.
      
      Fixes: 0aceb53e ("ovl: do not pass overlay dentry to ovl_get_inode()")

      Pull spectre/meltdown updates from Thomas Gleixner:
       "The next round of updates related to melted spectrum:
      
         - The initial set of spectre V1 mitigations:
      
             - Array index speculation blocker and its usage for syscall,
               fdtable and the n180211 driver.
      
             - Speculation barrier and its usage in user access functions
      
         - Make indirect calls in KVM speculation safe
      
         - Blacklisting of known to be broken microcodes so IPBP/IBSR are not
           touched.
      
         - The initial IBPB support and its usage in context switch
      
         - The exposure of the new speculation MSRs to KVM guests.
      
         - A fix for a regression in x86/32 related to the cpu entry area
      
         - Proper whitelisting for known to be safe CPUs from the mitigations.
      
         - objtool fixes to deal proper with retpolines and alternatives
      
         - Exclude __init functions from retpolines which speeds up the boot
           process.
      
         - Removal of the syscall64 fast path and related cleanups and
           simplifications
      
         - Removal of the unpatched paravirt mode which is yet another source
           of indirect unproteced calls.
      
         - A new and undisputed version of the module mismatch warning
      
         - A couple of cleanup and correctness fixes all over the place
      
        Yet another step towards full mitigation. There are a few things still
        missing like the RBS underflow mitigation for Skylake and other small
        details, but that's being worked on.
      
        That said, I'm taking a belated christmas vacation for a week and hope
        that everything is magically solved when I'm back on Feb 12th"
