Linus Torvalds 835c92d43b Merge branch 'work.const-qstr' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull qstr constification updates from Al Viro:
 "Fairly self-contained bunch - surprising lot of places passes struct
  qstr * as an argument when const struct qstr * would suffice; it
  complicates analysis for no good reason.

  I'd prefer to feed that separately from the assorted fixes (those are
  in #for-linus and with somewhat trickier topology)"

Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for MIPS for 4.8.  Also includes is a
  minor SSB cleanup as SSB code traditionally is merged through the MIPS
  tree:

      affect RM7000 ARC systems on reboot.

    - Rewrite r4k count/compare clockevent device registration such that
      min_delta_ticks/max_delta_ticks files are guaranteed to be
      initialized.
    - Only register r4k count/compare as clockevent device if we can
      assume the clock to be constant.
    - Fix MSA asm warnings in control reg accessors
    - uasm and tlbex fixes and tweaking.
    - Print segment physical address when EU=1.

 "Two more fixes in ACPI drivers, one in the ACPI EC driver

   - An ACPI EC driver fix from the 4.3 cycle may cause the ACPICA's

     large number of concurrent EC operations, so prevent that from
     happening by moving the EC handling into a separate workqueue with

 "A few more fixes and cleanups in the x86-64 low-level hibernation

  Specifics:

   - Prevent the low-level assembly hibernate code on x86-64 from
     referring to __PAGE_OFFSET directly as a symbol which doesn't work
     when the kernel identity mapping base is randomized, in which case
     __PAGE_OFFSET is a variable (Rafael Wysocki).

   - Avoid selecting CPU_FREQ_STAT by default as the statistics are not
     required for proper cpufreq operation (Borislav Petkov).

   - Add Skylake-X and Broadwell-X IDs to the intel_pstate's list of
     processors where out-of-band (OBB) control of P-states is possible
     and if that is in use, intel_pstate should not attempt to manage
     P-states (Srinivas Pandruvada).

   - Drop some unnecessary checks from the wakeup IRQ handling code in

Linus Torvalds f72035fad8 Merge tag 'usb-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull more USB updates from Greg KH:
 "Here are a few more straggler patches for USB for 4.8-rc1.

  Most of these are for the usb-serial driver tree.  All of those have
  been in linux-next for a long time, but missed my previous pull
  request to you.

  The remaining change is to fix up a staging tree build error, due to
  some USB gadget driver changes that went in.  I put it in this tree as
  it was for a USB driver and people are reporting the build error on
  your tree.

  All of these have been in linux-next for this week, and longer for the
  usb-serial changes"

* tag 'usb-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
  staging: emxx_udc: allow modular build
  USB: serial: use variable for status
  USB: serial: option: add support for Telit LE910 PID 0x1206
  USB: serial: cp210x: use kmemdup

Hiraku Toyooka e976e56423 ramoops: use persistent_ram_free() instead of kfree() for freeing prz
persistent_ram_zone(=prz) structures are allocated by persistent_ram_new(),
which includes vmap() or ioremap(). But they are currently freed by
kfree(). This uses persistent_ram_free() for correct this asymmetry usage.

Kees Cook 529182e204 ramoops: use DT reserved-memory bindings
Instead of a ramoops-specific node, use a child node of /reserved-memory.
This requires that of_platform_device_create() be explicitly called
for the node, though, since "/reserved-memory" does not have its own
"compatible" property.

Logan Gunthorpe a9c59ef774 ntb_test: Add a selftest script for the NTB subsystem
This script automates testing doorbells, scratchpads and memory windows
for an NTB device. It can be run locally, with the NTB looped
back to the same host or use SSH to remotely control the second host.

In the single host case, the script just needs to be passed two
arguments: a PCI ID for each side of the link. In the two host case
the -r option must be used to specify the remote hostname (which must
be SSH accessible and should probably have ssh-keys exchanged).

A sample run looks like this:

$ sudo ./ntb_test.sh 0000:03:00.1 0000:83:00.1 -p 29
