Pull ARM SoC DT updates from Arnd Bergmann:
 "The DT branch adds a lot of new stuff for additional SoC and board
  support.  The branch is the largest one and contains 513 out of the
  total 972 non-merge arm-soc changesets for 3.19.

  Most of the changes are about enabling additional on-chip devices for
  existing machines, but there are also an unusual number of new SoC
  types being added this time:

   - AMLogic Meson8
   - ARM Realview in DT mode
   - Allwinner A80
   - Broadcom BCM47081
   - Broadcom Cygnus
   - Freescale LS1021A
   - Freescale Vybrid 500 series
   - Mediatek MT6592, MT8127, MT8135
   - STMicroelectronics STiH410
   - Samsung Exynos4415

  The level of support for the above differs widely, some are just stubs
  with nothing more than CPU, memory and a UART, but others are fairly
  complete.  As usual, these get extended over time.

  There are also many new boards getting added, this is the list of
  model strings that are showing up in new dts files:

Pull ARM SoC driver updates from Arnd Bergmann:
 "These are changes for drivers that are intimately tied to some SoC and
  for some reason could not get merged through the respective subsystem
  maintainer tree.

  The largest single change here this time around is the Tegra
  iommu/memory controller driver, which gets updated to the new iommu DT
  binding.  More drivers like this are likely to follow for the
  following merge window, but we should be able to do those through the
  iommu maintainer.

  Other notable changes are:
   - reset controller drivers from the reset maintainer (socfpga, sti,
     berlin)
   - fixes for the keystone navigator driver merged last time
   - at91 rtc driver changes related to the at91 cleanups
   - ARM perf driver changes from Will Deacon

6c9e92476b Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Arnd Bergmann:
 "The remaining cleanups for 3.19 are to a large part result of
  devicetree conversion nearing completion on two other platforms
  besides AT91:

   - Like AT91, Renesas shmobile is in the process to migrate to DT and
     multiplatform, but using a different approach of doing it one SoC
     at a time.  For 3.19, the r8a7791 platform and associated "Koelsch"
     board are considered complete and we remove the non-DT
     non-multiplatform support for this.

   - The ARM Versatile Express has supported DT and multiplatform for a
     long time, but we have still kept the legacy board files around,
     because not all drivers were fully working before.  We have finally
     taken the last step to remove the board files.

  Other changes in this branch are preparation for the later branches or
  just unrelated to the more interesting changes:

   - The dts files for arm64 get moved into per-vendor directories for a
     clearer structure.

   - Some dead code removal (zynq, exynos, davinci, imx)

   - Using pr_*() macros more consistently instead of printk(KERN_*) in
     some platform code"

Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann:
 "On Atmel AT91, the conversion to device tree is now considered
  complete, and all machines that were not already converted in 3.18 are
  assumed to be unused and dropped by the maintainer.

  All remaining board files that were written in C are dropped, and the
  ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed
  altogether.  Cleaning up the last pieces was great fun, so I took the
  time to do some of the coding myself and removed several hundred code
  lines that ended up unused after the board files were done.

  There are still a couple of AT91 specific device drivers that are not
  converted to DT (CF, USB-OTG) and currently not working, and the
  platform itself is not "multiplatform"-enabled, but both issues are
  going to be taken care of in the 3.20 cycle.

  This is split out from the other cleanups purely based on the size of
  the branch"

====================
Intel Wired LAN Driver Updates 2014-12-09

This series contains updates to i40e and i40evf.

Jeff (me) provides a single patch to convert a macro to a static inline
function based on feedback from Joe Perches on a previous patch.

Shannon provides the remaining twelve patches against i40e.  Almost all
of Shannon's patches cleanup/fix NVM issues varying in range from
adding more detail to debug messages, to removing dead code, to fixing
NVM state transitions after an error.  Change the handy decoder interface
for admin queue return code to help catch and properly report the condition
as a useful errno rather than returning a misleading '0'.  Added a range
check to avoid any possible array index-out-of-bound issues.

v2:
 - fixed up patch 05 in the series to use the ARRAY_SIZE() macro as suggested
   by Sergei Shtylyov
 - fix up patch 13 to remove unnecessary parens in the return statement
   as suggested by Sergei Shtylyov

e5a4b0bb80 switch memcpy_to_msg() and skb_copy{,_and_csum}_datagram_msg() to primitives
... making both non-draining.  That means that tcp_recvmsg() becomes
non-draining.  And _that_ would break iscsit_do_rx_data() unless we
	a) make sure tcp_recvmsg() is uniformly non-draining (it is)
	b) make sure it copes with arbitrary (including shifted)
iov_iter (it does, all it uses is iov_iter primitives)
	c) make iscsit_do_rx_data() initialize ->msg_iter only once.

Fortunately, (c) is doable with minimal work and we are rid of one
the two places where kernel send/recvmsg users would be unhappy with
non-draining behaviour.

Actually, that makes all but one of ->recvmsg() instances iov_iter-clean.
The exception is skcipher_recvmsg() and it also isn't hard to convert
to primitives (iov_iter_get_pages() is needed there).  That'll wait
a bit - there's some interplay with ->sendmsg() path for that one.

   - seccomp from Akashi
   - some AArch32 instruction emulation, required by the Android folks
   - optimisations for exception entry/exit code, cmpxchg, pcpu atomics
   - mmu_gather range calculations moved into core code
   - EFI updates from Ard, including long-awaited SMBIOS support
   - /proc/cpuinfo fixes to align with the format used by arch/arm/
   - a few non-critical fixes across the architecture"

62dbe83015 macvlan: allow setting LRO independently of lower device
Since commit fbe168ba91 ("net: generic dev_disable_lro() stacked
device handling"), dev_disable_lro() zeroes NETIF_F_LRO feature flag
first for a macvlan device and then for its lower device. As an attempt
to set NETIF_F_LRO to zero is ignored, dev_disable_lro() issues a
warning and taints kernel.

Allowing NETIF_F_LRO to be set independently of the lower device
consists of three parts:

  - add the flag to hw_features to allow toggling it
  - allow setting it to 0 even if lower device has the flag set
  - add the flag to MACVLAN_FEATURES to restore copying from lower
    device on macvlan creation

The adminq init is run after the EMPR that is triggered by the
NVM update.  The final write command will cause the reset and
will want to wait for the ARQ event that signals the end of the

is probably already at INIT, but we set it so here anyway, and
clear the release_on_done flag as well.

74d0d0ede7 i40e: rework debug messages for NVM update
Rework the debug messages in the NVM update state machine so that we can
turn them on and off dynamically rather than forcing a recompile/reload.

These can now be turned on with something like:
	ethtool -s eth1 msglvl 0xf000008f
and off with:
	ethtool -s eth1 msglvl 0xf000000f

The high 0xf0000000 gets the driver's attention that we want to change the
internal debug flags, and the 0x80 bit is the NVM debug.

bf06f7a9ba i40e: let firmware catch the NVM busy error
The NVM update operations take time finish asynchronously, and follow-on
update requests need to wait for the current one to finish.  Early
firmware didn't handle this well, so the code had to track the busy state.
The released firmware handles the busy state correctly, returning
I40E_AQ_RC_EBUSY if an update is still in progress, so the code no longer
needs to track this.
