Pull afs updates from David Howells:
 "Four fixes:

   - add a missing put

   - two fixes to reset the address iteration cursor correctly

   - fix setting up the fileserver iteration cursor.

  Two cleanups:

   - remove some dead code

   - rearrange a function to be more logically laid out

  And one new feature:

   - Support AFS dynamic root.

     With this one should be able to do, say:

        mkdir /afs
        mount -t afs none /afs -o dyn

     to create a dynamic root and then, provided you have keyutils
     installed, do:

        ls /afs/grand.central.org

     and:

        ls /afs/umich.edu

     to list the root volumes of both those organisations' AFS cells
     without requiring any other setup (the kernel upcall to a program
     in the keyutils package to do DNS access as does NFS)"

Pull IOMMU updates from Joerg Roedel:
 "This time there are not a lot of changes coming from the IOMMU side.

  That is partly because I returned from my parental leave late in the
  development process and probably partly because everyone was busy with

  IOMMU work. So here are the few changes that queued up for this merge
  window:

   - 5-level page-table support for the Intel IOMMU.

   - error reporting improvements for the AMD IOMMU driver

   - additional DT bindings for ipmmu-vmsa (Renesas)

   - masking of __user pointers prior to deference in uaccess routines

  Spectre v2 mitigation update:

Commit 0fbc0b67 ("cris: remove arch specific early DT functions")
was a bit overzealous in removing the CRIS DT handling,

This lead to a complete link failure for all SoCs in

Merge tag 'riscv-for-linus-4.16-merge_window' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux

Pull RISC-V updates from Palmer Dabbelt:
 "This contains the fixes we'd like to target for the 4.16 merge window.
  It's not as much as I was originally hoping to do but between glibc,
  the chip, and FOSDEM there just wasn't enough time to get everything
  put together. As such, this merge window is essentially just going to
  be small changes. This includes mostly cleanups:

   - A build fix failure to the audit test cases.

     RISC-V doesn't have renameat because the generic syscall ABI moved
     to renameat2 by the time of our port. The syscall audit test cases
     don't understand this, so I added a trivial fix. This went through
     mailing list review during the 4.15 merge window, but nobody has
     picked it up so I think it's best to just do this here.

   - The removal of our command-line argument processing code. The
     "mem_end" stuff was broken and the rest duplicated generic device
     tree code. The generic code was already being called.

   - Some unused/redundant code has been removed, including
     __ARCH_HAVE_MMU, current_pgdir, and the initialization of
     init_mm.pgd.

   - SUM is disabled upon taking a trap, which means that user memory is
     protected during traps taking inside copy_{to,from}_user().

   - The sptbr CSR has been renamed to satp in C code. We haven't
     changed the assembly code in order to maintain compatibility with
     binutils 2.29, which doesn't understand the new name.

  Additionally, we're adding some new features:

   - Basic ftrace support, thanks to Alan Kao!

   - Support for ZONE_DMA32.

     This is necessary for all the normal reasons, but also to deal with
     a deficiency in the Xilinx PCIe controller we're using on our
     FPGA-based systems. While the ZONE_DMA32 addition should be
     sufficient for most uses, it doesn't complete the fix for the
     Xilinx controller.

   - TLB shootdowns now only target the harts where they're necessary,
     instead of applying to all harts in the system.

  These patches have all been sitting on our linux-next branch for a
  while now. Due to time constraints this is all I feel comfortable
  submitting during the 4.16 merge window, hopefully we'll do better
  next time!"

[ Note to self: "harts" is RISC-V speak for "hardware threads".  I had
  to look that up.    - Linus ]

Pull MIPS fixes from James Hogan:
 "A couple of MIPS fixes for 4.16-rc1, including an important regression
  in 4.15 and a rather more longstanding corner case build fix.

  These are separate from the main pull request as one of the bugs fixed
  was only recently introduced in v4.15-rc8.

   - Fix CPS regression on older binutils due to MIPS_ISA_LEVEL_RAW fix
     (4.15)

   - Fix allmodconfig + CONFIG_MACH_TX49XX=y builds due to incorrect use
     of IS_ENABLED() (2.6.28)"

Pull MIPS updates from James Hogan:
 "These are the main MIPS changes for 4.16.

  Rough overview:

   (1) Basic support for the Ingenic JZ4770 based GCW Zero open-source
       handheld video game console

   (2) Support for the Ranchu board (used by Android emulator)

   (3) Various cleanups and misc improvements

  More detailed summary:

  Fixes:
   - Fix generic platform's USB_*HCI_BIG_ENDIAN selects (4.9)
   - Fix vmlinuz default build when ZBOOT selected
   - Fix clean up of vmlinuz targets
   - Fix command line duplication (in preparation for Ingenic JZ4770)

  Miscellaneous:
   - Allow Processor ID reads to be to be optimised away by the compiler
     (improves performance when running in guest)
   - Push ARCH_MIGHT_HAVE_PC_SERIO/PARPORT down to platform level to
     disable on generic platform with Ranchu board support
   - Add helpers for assembler macro instructions for older assemblers
   - Use assembler macro instructions to support VZ, XPA & MSA
     operations on older assemblers, removing C wrapper duplication
   - Various improvements to VZ & XPA assembly wrappers
   - Add drivers/platform/mips/ to MIPS MAINTAINERS entry

  Minor cleanups:
   - Misc FPU emulation cleanups (removal of unnecessary include, moving
     macros to common header, checkpatch and sparse fixes)
   - Remove duplicate assignment of core in play_dead()
   - Remove duplication in watchpoint handling
   - Remove mips_dma_mapping_error() stub
   - Use NULL instead of 0 in prepare_ftrace_return()
   - Use proper kernel-doc Return keyword for
     __compute_return_epc_for_insn()
   - Remove duplicate semicolon in csum_fold()

  Platform support:

  Broadcom:
   - Enable ZBOOT on BCM47xx

  Generic platform:
   - Add Ranchu board support, used by Android emulator
   - Fix machine compatible string matching for Ranchu
   - Support GIC in EIC mode

  Ingenic platforms:
   - Add DT, defconfig and other support for JZ4770 SoC and GCW Zero
   - Support dynamnic machine types (i.e. JZ4740 / JZ4770 / JZ4780)
   - Add Ingenic JZ4770 CGU clocks
   - General Ingenic clk changes to prepare for JZ4770 SoC support
   - Use common command line handling code
   - Add DT vendor prefix to GCW (Game Consoles Worldwide)

  Loongson:
   - Add MAINTAINERS entry for Loongson2 and Loongson3 platforms
   - Drop 32-bit support for Loongson 2E/2F devices
   - Fix build failures due to multiple use of 'MEM_RESERVED'"

This driver used the wrong OF-helper when looking up the optional
capture-codec child node during probe. Instead of searching just
children of the sound node, a tree-wide depth-first search starting at
the unrelated platform node was done. Not only could this end up
matching an unrelated node or no node at all; the platform node could
also be prematurely freed since of_find_node_by_name() drops a reference
to its first argument. This particular pattern has been observed leading
to crashes after probe deferrals in other drivers.

Fix this by dropping the broken call to of_find_node_by_name() and
keeping only the second, correct lookup using of_get_child_by_name()
while taking care not to bail out if the optional node is missing.

Note that this also addresses two capture-codec node-reference leaks
(one for each of the original helper calls).

Compile tested only.

This fix a bug in dapm_widget_power_read_file(),
where it may sent opposite order of source/sink widget
into the p->connected().

for example,
static int connected_check(source, sink);
{"w_sink", NULL, "w_source", connected_check}

the dapm_widget_power_read_file() will query p->connected()
in following case
	p->conneted("w_source", "w_sink")
	p->conneted("w_sink", "w_source")
we should avoid the last case, since it's the wrong order (source/sink)
as declared in snd_soc_dapm_route.
