      Pull Exynos platform DT fix from Grant Likely:
 "Device tree Exynos bug fix for v3.16-rc7

  This bug fix has been brewing for a while.  I hate sending it to you
  so late, but I only got confirmation that it solves the problem this
  past weekend.  The diff looks big for a bug fix, but the majority of
  it is only executed in the Exynos quirk case.  Unfortunately it
  required splitting early_init_dt_scan() in two and adding quirk
  handling in the middle of it on ARM.

  Exynos has buggy firmware that puts bad data into the memory node.
  Commit 1c2f87c2 ("ARM: Get rid of meminfo") exposed the bug by
  dropping the artificial upper bound on the number of memory banks that
  can be added.  Exynos fails to boot after that commit.  This branch
  fixes it by splitting the early DT parse function and inserting a
  fixup hook.  Exynos uses the hook to correct the DT before parsing
  memory regions"

      Revert "cdc_subset: deal with a device that needs reset for timeout" · 1d8fcba1
      Linus Torvalds authored 
      This reverts commit 20fbe3ae.

As reported by Stephen Rothwell, it causes compile failures in certain
configurations:

  drivers/net/usb/cdc_subset.c:360:15: error: 'dummy_prereset' undeclared here (not in a function)
    .pre_reset = dummy_prereset,
                 ^
  drivers/net/usb/cdc_subset.c:361:16: error: 'dummy_postreset' undeclared here (not in a function)
    .post_reset = dummy_postreset,
                  ^

      Pull networking fixes from David Miller:

 1) Make fragmentation IDs less predictable, from Eric Dumazet.

 2) TSO tunneling can crash in bnx2x driver, fix from Dmitry Kravkov.

 3) Don't allow NULL msg->msg_name just because msg->msg_namelen is
    non-zero, from Andrey Ryabinin.

 4) ndm->ndm_type set using wrong macros, from Jun Zhao.

 5) cdc-ether devices can come up with entries in their address filter,
    so explicitly clear the filter after the device initializes.  From
    Oliver Neukum.

 6) Forgotten refcount bump in xfrm_lookup(), from Steffen Klassert.

 7) Short packets not padded properly, exposing random data, in bcmgenet
    driver.  Fix from Florian Fainelli.

 8) xgbe_probe() doesn't return an error code, but rather zero, when
    netif_set_real_num_tx_queues() fails.  Fix from Wei Yongjun.

 9) USB speed not probed properly in r8152 driver, from Hayes Wang.

10) Transmit logic choosing the outgoing port in the sunvnet driver
    needs to consider a) is the port actually up and b) whether it is a
    switch port.  Fix from David L Stevens.

      x86/xen: safely map and unmap grant frames when in atomic context · b7dd0e35
      David Vrabel authored 
      arch_gnttab_map_frames() and arch_gnttab_unmap_frames() are called in
atomic context but were calling alloc_vm_area() which might sleep.

Also, if a driver attempts to allocate a grant ref from an interrupt
and the table needs expanding, then the CPU may already by in lazy MMU
mode and apply_to_page_range() will BUG when it tries to re-enable
lazy MMU mode.

These two functions are only used in PV guests.

Introduce arch_gnttab_init() to allocates the virtual address space in
advance.

Avoid the use of apply_to_page_range() by using saving and using the
array of PTE addresses from the alloc_vm_area() call (which ensures
that the required page tables are pre-allocated).
