Pull partial readlink cleanups from Miklos Szeredi.

This is the uncontroversial part of the readlink cleanup patch-set that
simplifies the default readlink handling.

Miklos and Al are still discussing the rest of the series.

* git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs:
  vfs: make generic_readlink() static
  vfs: remove ".readlink = generic_readlink" assignments
  vfs: default to generic_readlink()
  vfs: replace calling i_op->readlink with vfs_readlink()
  proc/self: use generic_readlink
  ecryptfs: use vfs_get_link()
  bad_inode: add missing i_op initializers

Pull vfs updates from Al Viro:

 - more ->d_init() stuff (work.dcache)

 - pathname resolution cleanups (work.namei)

 - a few missing iov_iter primitives - copy_from_iter_full() and
   friends. Either copy the full requested amount, advance the iterator
   and return true, or fail, return false and do _not_ advance the
   iterator. Quite a few open-coded callers converted (and became more
   readable and harder to fuck up that way) (work.iov_iter)

 - several assorted patches, the big one being logfs removal

  logfs: remove from tree
  vfs: fix put_compat_statfs64() does not handle errors

Current code returns EXDEV when a directory would need to be copied up to
move.  We could copy up the directory tree in this case, but there's
another, simpler solution: point to old lower directory from moved upper
directory.

This is achieved with a "trusted.overlay.redirect" xattr storing the path
relative to the root of the overlay.  After such attribute has been set,
the directory can be moved without further actions required.

This is a backward incompatible feature, old kernels won't be able to
correctly mount an overlay containing redirected directories.

The quirk for file locks and leases no longer applies.

Add missing info about renaming directory residing on lower layer.

Pull PCI updates from Bjorn Helgaas:
 "PCI changes:

   - add support for PCI on ARM64 boxes with ACPI. We already had this
     for theoretical spec-compliant hardware; now we're adding quirks
     for the actual hardware (Cavium, HiSilicon, Qualcomm, X-Gene)

   - add runtime PM support for hotplug ports

   - enable runtime suspend for Intel UHCI that uses platform-specific
     wakeup signaling

   - add yet another host bridge registration interface. We hope this is
     extensible enough to subsume the others

   - expose device revision in sysfs for DRM

   - to avoid device conflicts, make sure any VF BAR updates are done
     before enabling the VF

   - avoid unnecessary link retrains for ASPM

   - allow INTx masking on Mellanox devices that support it

   - allow access to non-standard VPD for Chelsio devices

   - update Broadcom iProc support for PAXB v2, PAXC v2, inbound DMA,
     etc

   - update Rockchip support for max-link-speed

   - add NVIDIA Tegra210 support

   - add Layerscape LS1046a support

   - update R-Car compatibility strings

   - add Qualcomm MSM8996 support

   - remove some uninformative bootup messages"

Pull xfs updates from Dave Chinner:
 "There is quite a varied bunch of stuff in this update, and some of it
  you will have already merged through the ext4 tree which imported the
  dax-4.10-iomap-pmd topic branch from the XFS tree.

  There is also a new direct IO implementation that uses the iomap
  infrastructure. It's much simpler, faster, and has lower IO latency
  than the existing direct IO infrastructure.

  Summary:
   - DAX PMD faults via iomap infrastructure
   - Direct-io support in iomap infrastructure
   - removal of now-redundant XFS inode iolock, replaced with VFS
     i_rwsem
   - synchronisation with fixes and changes in userspace libxfs code
   - extent tree lookup helpers
   - lots of little corruption detection improvements to verifiers
   - optimised CRC calculations
   - faster buffer cache lookups
   - deprecation of barrier/nobarrier mount options - we always use
     REQ_FUA/REQ_FLUSH where appropriate for data integrity now
   - cleanups to speculative preallocation
   - miscellaneous minor bug fixes and cleanups"
