Sudarsana Kalluru 91420b83ba qed: Add support for changing LED state
Physical LEDs are being controlled by the management FW.
This adds the qed functionality required to request management FW to
change the LED configuration, as well as the necessary APIs for this
functionality to later be used by the protocol drivers.

Eric Dumazet 93d05d4a32 net: provide generic busy polling to all NAPI drivers
NAPI drivers no longer need to observe a particular protocol
to benefit from busy polling (CONFIG_NET_RX_BUSY_POLL=y)

napi_hash_add() and napi_hash_del() are automatically called
from core networking stack, respectively from
netif_napi_add() and netif_napi_del()

This patch depends on free_netdev() and netif_napi_del() being
called from process context, which seems to be the norm.

Drivers might still prefer to call napi_hash_del() on their
own, since they might combine all the rcu grace periods into
a single one, knowing their NAPI structures lifetime, while
core networking stack has no idea of a possible combining.

Once this patch proves to not bring serious regressions,
we will cleanup drivers to either remove napi_hash_del()
or provide appropriate rcu grace periods combining.

napi_hash_del() will soon be used from both drivers (if they want)
or core networking stack.

Callers are responsibles to ensure an RCU grace period is respected
before freeing napi structure : napi_hash_del() can signal if
this RCU grace period is needed or not.

Eric Dumazet 52bd2d62ce net: better skb->sender_cpu and skb->napi_id cohabitation
skb->sender_cpu and skb->napi_id share a common storage,
and we had various bugs about this.

We had to call skb_sender_cpu_clear() in some places to
not leave a prior skb->napi_id and fool netdev_pick_tx()

As suggested by Alexei, we could split the space so that
these errors can not happen.

0 value being reserved as the common (not initialized) value,
let's reserve [1 .. NR_CPUS] range for valid sender_cpu,
and [NR_CPUS+1 .. ~0U] for valid napi_id.

This will allow proper busy polling support over tunnels.

Vlad Yasevich 28f9ee22bc vlan: Do not put vlan headers back on bridge and macvlan ports
When a vlan is configured with REORDER_HEADER set to 0, the vlan
header is put back into the packet and makes it appear that
the vlan header is still there even after it's been processed.
This posses a problem for bridge and macvlan ports.  The packets
passed to those device may be forwarded and at the time of the
forward, vlan headers end up being unexpectedly present.

With the patch, we make sure that we do not put the vlan header
back (when REORDER_HEADER is 0) if a bridge or macvlan has
been configured on top of the vlan device.

Tariq Toukan 66189961e9 net/mlx5e: Added self loopback prevention
Prevent outgoing multicast frames from looping back to the RX queue.

By introducing new HW capability self_lb_en_modifiable, which indicates
the support to modify self_lb_en bit in modify_tir command.

When this capability is set we can prevent TIRs from sending back
loopback multicast traffic to their own RQs, by "refreshing TIRs" with
modify_tir command, on every time new channels (SQs/RQs) are created at
device open.
This is needed since TIRs are static and only allocated once on driver
load, and the loopback decision is under their responsibility.

Fixes issues of the kind:
"IPv6: eth2: IPv6 duplicate address fe80::e61d:2dff:fe5c:f2e9 detected!"
The issue is seen since the IPv6 solicitations multicast messages are
loopedback and the network stack thinks they are coming from another host.

Here's the branch of chrome platform changes for v4.4. Some have been queued
 up for the full 4.3 release cycle since I forgot to send them in for that

 context, which depends on a sysfs patch acked by Greg.

 "There's no need to keep an extra wrapper structure per item and the

Now that the xattr handler is passed to the xattr handler operations, we
can use the same get and set operations for the user, trusted, and security
xattr namespaces.  In those namespaces, we can access the full attribute
name by "reattaching" the name prefix the vfs has skipped for us.  Add a
xattr_full_name helper to make this obvious in the code.

For the "system.posix_acl_access" and "system.posix_acl_default"
attributes, handler->prefix is the full attribute name; the suffix is the
empty string.

Linus Torvalds 3370b69eb0 Four changes:
- x86: work around two nasty cases where a benign exception occurs while
 another is being delivered.  The endless stream of exceptions causes an
 infinite loop in the processor, which not even NMIs or SMIs can interrupt;
 in the virt case, there is no possibility to exit to the host either.
 
 - x86: support for Skylake per-guest TSC rate.  Long supported by AMD,
 the patches mostly move things from there to common arch/x86/kvm/ code.
 
 - generic: remove local_irq_save/restore from the guest entry and exit
 paths when context tracking is enabled.  The patches are a few months
 old, but we discussed them again at kernel summit.  Andy will pick up
 from here and, in 4.5, try to remove it from the user entry/exit paths.

Netfilter fixes for net

The following patchset contains Netfilter fixes for your net tree. This
large batch that includes fixes for ipset, netfilter ingress, nf_tables
dynamic set instantiation and a longstanding Kconfig dependency problem.
More specifically, they are:

1) Add missing check for empty hook list at the ingress hook, from
   Florian Westphal.

2) Input and output interface are swapped at the ingress hook,
   reported by Patrick McHardy.

3) Resolve ipset extension alignment issues on ARM, patch from Jozsef
   Kadlecsik.

4) Fix bit check on bitmap in ipset hash type, also from Jozsef.

5) Release buckets when all entries have expired in ipset hash type,
   again from Jozsef.

6) Oneliner to initialize conntrack tuple object in the PPTP helper,
   otherwise the conntrack lookup may fail due to random bits in the
   structure holes, patch from Anthony Lineham.

7) Silence a bogus gcc warning in nfnetlink_log, from Arnd Bergmann.

8) Fix Kconfig dependency problems with TPROXY, socket and dup, also
   from Arnd.

9) Add __netdev_alloc_pcpu_stats() to allow creating percpu counters
   from atomic context, this is required by the follow up fix for
   nf_tables.

10) Fix crash from the dynamic set expression, we have to add new clone
    operation that should be defined when a simple memcpy is not enough.
    This resolves a crash when using per-cpu counters with new Patrick
    McHardy's flow table nft support.

Merge tag 'pwm/for-4.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "This round contains a couple of new drivers for the Marvell Berlin
  family of SoCs, various SoCs from Renesas and Broadcom as well as the
  backlight PWM present on MediaTek SoCs.

  Further existing drivers are extended to support a wider range of
  hardware.

  The remaining patches are minor fixes and cleanups across the board.

  Note that one of the patches included in this pull request is against
  arch/unicore32.  I've included it here because I couldn't get a
  response from Guan Xuetao and I consider the change low-risk.
  Equivalent patches have been merged and tested in Samsung and PXA
  trees.  The goal is to finally get rid of legacy code paths that have
  repeatedly been causing headaches"

Alex Smith c0a9f72c15 irqchip: irq-mips-gic: Provide function to map GIC user section
The GIC provides a "user-mode visible" section containing a mirror of
the counter registers which can be mapped into user memory. This will
be used by the VDSO time function implementations, so provide a
function to map it in.

When the GIC is not enabled in Kconfig a dummy inline version of this
function is provided, along with "#define gic_present 0", so that we
don't have to litter the VDSO code with ifdefs.

[markos.chandras@imgtec.com:
  - Move mapping code to arch/mips/kernel/vdso.c and use a resource
    type to get the GIC usermode information
  - Avoid renaming function arguments and use __gic_base_addr to hold
    the base GIC address prior to ioremap.]

This function pointer was removed as part of this commit:

Ross Zwisler 5c50002963 vfs: remove unused wrapper block_page_mkwrite()
The function currently called "__block_page_mkwrite()" used to be called
"block_page_mkwrite()" until a wrapper for this function was added by:

commit 24da4fab5a ("vfs: Create __block_page_mkwrite() helper passing
	error values back")

This wrapper, the current "block_page_mkwrite()", is currently unused.
__block_page_mkwrite() is used directly by ext4, nilfs2 and xfs.

Remove the unused wrapper, rename __block_page_mkwrite() back to
block_page_mkwrite() and update the comment above block_page_mkwrite().

as currently seen when building sparc:allmodconfig.

Introduce a static inline function if OF_ADDRESS is not configured to fix
the build failure. Return OF_BAD_ADDR in this case. For this to work, the
definition of OF_BAD_ADDR has to be moved outside CONFIG_OF conditional
code.

Linus Torvalds b44a3d2a85 ARM: SoC driver updates for v4.4
As we've enabled multiplatform kernels on ARM, and greatly done away with
 the contents under arch/arm/mach-*, there's still need for SoC-related
 drivers to go somewhere.
 
 Many of them go in through other driver trees, but we still have
 drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
 that might be shared between ARM and ARM64 (or just in general makes
 sense to not have under the architecture directory).
 
 This branch contains mostly such code:
 
 - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate
   with power management blocks on these SoCs for use by clock, regulator and
   bus frequency drivers.
 - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs.
 - Drivers for ARM's SCPI (System Control Processor). Not to be confused with
   PSCI (Power State Coordination Interface). SCPI is used to communicate with
   the assistant embedded cores doing power management, and we have yet to see
   how many of them will implement this for their hardware vs abstracting in
   other ways (or not at all like in the past).
 - To make confusion between SCPI and PSCI more likely, this release also
   includes an update of PSCI to interface version 1.0.
 - Rockchip support for power domains.
 - A driver to talk to the firmware on Raspberry Pi.

Linus Torvalds a5e1d715a8 ARM: SoC cleanups for v4.4
Again we have a sizable (but not huge) cleanup branch with a net delta of about
 -3k lines.
 
 Main contents here is:
 
  - A bunch of development/cleanup of a few PXA boards
  - Removal of bockw platforms on shmobile, since the platform has now gone
    completely multiplatform. Whee!
  - move of the 32kHz timer on OMAP to a proper timesource
  - Misc cleanup of older OMAP material (incl removal of one board file)
  - Switch over to new common PWM lookup support for several platforms
 
 There's also a handful of other cleanups across the tree, but the above are
 the major pieces.

Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups from Olof Johansson:
 "Again we have a sizable (but not huge) cleanup branch with a net delta
  of about -3k lines.

  Main contents here is:

   - A bunch of development/cleanup of a few PXA boards
   - Removal of bockw platforms on shmobile, since the platform has now
     gone completely multiplatform.  Whee!
   - move of the 32kHz timer on OMAP to a proper timesource
   - Misc cleanup of older OMAP material (incl removal of one board
     file)
   - Switch over to new common PWM lookup support for several platforms

  There's also a handful of other cleanups across the tree, but the
  above are the major pieces"

Merge tag 'libnvdimm-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "Outside of the new ACPI-NFIT hot-add support this pull request is more
  notable for what it does not contain, than what it does.  There were a
  handful of development topics this cycle, dax get_user_pages, dax
  fsync, and raw block dax, that need more more iteration and will wait
  for 4.5.

  The patches to make devm and the pmem driver NUMA aware have been in
  -next for several weeks.  The hot-add support has not, but is
  contained to the NFIT driver and is passing unit tests.  The coredump
  support is straightforward and was looked over by Jeff.  All of it has
  received a 0day build success notification across 107 configs.

  Summary:

   - Add support for the ACPI 6.0 NFIT hot add mechanism to process
     updates of the NFIT at runtime.

   - Teach the coredump implementation how to filter out DAX mappings.

   - Introduce NUMA hints for allocations made by the pmem driver, and
     as a side effect all devm allocations now hint their NUMA node by
