72897fa31f ARM: sun8i: h2+: enable USB OTG for Orange Pi Zero board
Orange Pi Zero board features a USB OTG port, which has a ID pin, and
can be used to power up the board. However, even if the board is powered
via +5V pin in GPIO/expansion headers, the VBUS in the OTG port cannot
be powered up, thus it's impossible to use it in host mode with simple
OTG cables.

Add support for it in peripheral mode.

If someone really want to use it in host mode, the mode of PHY can be
switch via sysfs, then use a powered USB OTG cable or powered USB HUB to
power up external USB devices.

2e77b3afdd ARM: sun8i: h3: enable USB OTG on Orange Pi One
Orange Pi One features a MicroUSB port that can work in both host mode
and peripheral mode.

When in host mode, its VBUS is controlled via a GPIO; when in peripheral
mode, its VBUS cannot be used to power up the board.

Add support for this port.

0127216f22 arm: sun8i: h3: split Allwinner H3 .dtsi
The new Allwinner H5 SoC is pin-compatible to the H3 SoC, but with the
Cortex-A7 cores replaced by Cortex-A53 cores and the MMC controller
updated. So we should really share almost the whole .dtsi.
In preparation for that move the peripheral parts of the existing
sun8i-h3.dtsi into a new sunxi-h3-h5.dtsi.
The actual sun8i-h3.dtsi then includes that and defines the H3 specific
parts on top of it.

a0f4e1836b arm: sun8i: h3: correct the GIC compatible in H3 to gic-400
According to the datasheets provided by Allwinner, both Allwinner H3 and
H5 use GIC-400 as their interrupt controller.

For better device tree reusing, correct the GIC compatible in H3 DTSI to
"arm,gic-400", thus this node can be reused in H5.

 "A fix and regression test case for nvdimm namespace label

     device / dax-filesytem, or a device-dax character device.

     A namespace is an object that other operating environment and

     from an nvdimm.

     The label metadata contains a checksum that Linux was not
     calculating correctly leading to other environments rejecting the

   These have received a build success notification from the kbuild

606ed721af Xtensa improvements for v4.11:
- clean up bootable image build targets: provide separate 'Image',
   'zImage' and 'uImage' make targets that only build corresponding
   image type. Make 'all' build all images appropriate for a platform;
 - allow merging vectors code into .text section as a preparation step
   for XIP support;

a1a0db36d8 ARM: SoC: late DT updates for v4.11
These updates have been kept in a separate branch mostly because
 they rely on updates to the respective clk drivers to keep the
 shared header files in sync.
 
 This includes two branches for arm64 dt updates, both following up
 on earlier changes for the same platforms that are already merged:
 
 Samsung:
   - add USB3 support in Exynos7
   - minor PM related updates
 
 Amlogic:
   - new machines: WeTek Set-top-boxes
   - various devices added to DT
 
 There are also a couple of bugfixes that trickled in since the
 start of the merge window:
 
 - The moxart_defconfig was not building the intended platform
 - CPU-hotplug was broken on ux500
 - Coresight was broken on Juno (never worked)

590dce2d49 Merge branch 'rebased-statx' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs 'statx()' update from Al Viro.

This adds the new extended stat() interface that internally subsumes our
previous stat interfaces, and allows user mode to specify in more detail
what kind of information it wants.

It also allows for some explicit synchronization information to be
passed to the filesystem, which can be relevant for network filesystems:
is the cached value ok, or do you need open/close consistency, or what?

From David Howells.

Andreas Dilger points out that the first version of the extended statx
interface was posted June 29, 2010:

   - Two fixes for a regression in this window from Jan, fixing a
     problem with one of his earlier patches dealing with queue vs bdi

Pull sched.h split-up from Ingo Molnar:
 "The point of these changes is to significantly reduce the
  <linux/sched.h> header footprint, to speed up the kernel build and to
  have a cleaner header structure.

  After these changes the new <linux/sched.h>'s typical preprocessed
  size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K
  lines), which is around 40% faster to build on typical configs.

  Not much changed from the last version (-v2) posted three weeks ago: I
  eliminated quirks, backmerged fixes plus I rebased it to an upstream
  SHA1 from yesterday that includes most changes queued up in -next plus
  all sched.h changes that were pending from Andrew.

  I've re-tested the series both on x86 and on cross-arch defconfigs,
  and did a bisectability test at a number of random points.

  I tried to test as many build configurations as possible, but some
  build breakage is probably still left - but it should be mostly
  limited to architectures that have no cross-compiler binaries
  available on kernel.org, and non-default configurations"

37411cad63 rxrpc: Fix potential NULL-pointer exception
Fix a potential NULL-pointer exception in rxrpc_do_sendmsg().  The call
state check that I added should have gone into the else-body of the
if-statement where we actually have a call to check.

Found by CoverityScan CID#1414316 ("Dereference after null check").

====================
nfp: RX and XDP buffer fixes

Two trivial fixes for code introduced with XDP support.  First
one corrects the buffer size we populate a register with.  The
register is designed to be used for scatter transfers which
the driver (and most FWs) don't support so it's not critical.
The other one for DMA direction is mostly cosmetic, DMA API
doesn't seem to care today about the precise direction in sync
calls.

d58cebb79b nfp: correct DMA direction in XDP DMA sync
dma_sync_single_for_*() takes the direction in which the buffer
was mapped, not the direction of the sync.  We should sync XDP
buffers bidirectionally.

9383b33771 nfp: don't tell FW about the reserved buffer space
Since commit c0f031bc88 ("nfp_net: use alloc_frag() and build_skb()")
we are allocating buffers which have to hold both the data and skb to
be created in place by build_skb().

FW should only be told about the buffer space it can DMA to, that
is without the build_skb() headroom and tailroom.  Note: firmware
applications should validate the buffers against both MTU and
free list buffer size so oversized packets would not pass through
the NIC anyway.

====================
net: ethernet: bgmac: bug fixes

Changes in v5:
* Rebased to the latest code and fixed up a compile error due to the
  mac_addr struct going away (found by David Miller)

Changes in v4:
* Added the udelays from the previous code (per David Miller)

Changes in v3:
* Reworked the init sequence patch to only remove the device reset if
  the device is actually in reset.  Given that this code doesn't bear
  much resemblance to the original code, I'm changing the author of the
  patch.  This was tested on NS2 SVK.

Changes in v2:
* Reworked the first match to make it more obvious what portions of the
  register were being preserved (Per Rafal Mileki)
* Style change to reorder the function variables in patch 2 (per Sergei
  Shtylyov)

16206524f6 net: ethernet: bgmac: init sequence bug
Fix a bug in the 'bgmac' driver init sequence that blind writes for init
sequence where it should preserve most bits other than the ones it is
deliberately manipulating.

The code now checks to see if the adapter needs to be brought out of
reset (where as before it was doing an IDM write to bring it out of
reset regardless of whether it was in reset or not).  Also, removed
unnecessary usleeps (as there is already a read present to flush the
IDM writes).

xen-netback: update memory leak fix to avoid BUG

Commit 9a6cdf52b8 "xen-netback: fix memory leaks on XenBus disconnect"
added missing code to fix a memory leak by calling vfree() in the
appropriate place.
Unfortunately subsequent commit f16f1df65f "xen-netback: protect
resource cleaning on XenBus disconnect" then wrapped this call to vfree()
in a spin lock, leading to a BUG due to incorrect context.

Intel Wired LAN Driver Updates 2017-03-02

This series contains fixes to ixgbe only.

Paolo fixes the driver so that you can actually update the RSS key value
via ethtool.

Alex fixes an issue on architectures that have a cache line size larger
than 64 Bytes, where the amount of headroom for the frame starts
shrinking.  To take this into account, Alex adds one small check so that
we compare the max_frame to the amount of actual data we can store, so
we will automatically enable 3K receive buffers as soon as the maximum
frame size we can handle drops below the standard Ethernet MTU.
