9e9dc7d959 mfd: stmpe: root out static GPIO and IRQ assignments
The only platform using the STMPE expander now boots from
device tree using all-dynamic GPIO and IRQ number assignments, so
remove the mechanism to pass this from the device tree entirely.

5c992afcf8 clk: tegra: Fix xusb_hs_src clock hierarchy
Currently the Tegra1x4 clock init code hard-codes the mux setting
for xusb_hs_src and treats it as a fixed-factor clock.  It is,
however, a mux which can be parented by either xusb_ss_src/2 or
pll_u_60M.  Add the fixed-factor clock xusb_ss_div2 and put an
entry in periph_clks[] for the xusb_hs_src mux.

ad69674e73 of/irq: do irq resolution in platform_get_irq_byname()
The commit 9ec36cafe4
"of/irq: do irq resolution in platform_get_irq" from Rob Herring -
moves resolving of the interrupt resources in platform_get_irq().
But this solution isn't complete because platform_get_irq_byname()
need to be modified the same way.

Hence, fix it by adding interrupt resolution code at the
platform_get_irq_byname() function too.

f8712528ae usb: patches for v3.16 merge window
Not a lot here during this merge window. Mostly we just have
 the usual miscellaneous patches (removal of unnecessary prints,
 proper dependencies being added to Kconfig, build warning fixes,
 new device ID, etc.
 
 Other than those, the only important new features are the
 new support for OS Strings which should help Linux Gadget
 Drivers behave better under MS Windows. Also Babble Recovery
 implementation for MUSB on AM335x. Lastly, we also have
 ARCH_QCOM PHY support though phy-msm.

11d200e95f lib: add glibc style strchrnul() variant
The strchrnul() variant helpfully returns a the end of the string
instead of a NULL if the requested character is not found. This can
simplify string parsing code since it doesn't need to expicitly check
for a NULL return. If a valid string pointer is passed in, then a valid
null terminated string will always come back out.

be52c9e96a openvswitch: Avoid assigning a NULL pointer to flow actions.
Flow SET can accept an empty set of actions, with the intended
semantics of leaving existing actions unmodified.  This seems to have
been brokin after OVS 1.7, as we have assigned the flow's actions
pointer to NULL in this case, but we never check for the NULL pointer
later on.  This patch restores the intended behavior and documents it
in the include/linux/openvswitch.h.

ecc8fb11cd net/mlx4_core: Deprecate use_prio module parameter
use_prio was added as part of an infrastructure for running FCoE in A0 mode.
FCoE didn't get into Mellanox Upstream driver, and when it will, it won't be
using A0 steering mode.

Therefore we can safely deprecate this module parameter without hurting any
existing user.

16e4d93f6d NFSD: Ignore client's source port on RDMA transports
An NFS/RDMA client's source port is meaningless for RDMA transports.
The transport layer typically sets the source port value on the
connection to a random ephemeral port.

Currently, NFS server administrators must specify the "insecure"
export option to enable clients to access exports via RDMA.

But this means NFS clients can access such an export via IP using an
ephemeral port, which may not be desirable.

This patch eliminates the need to specify the "insecure" export
option to allow NFS/RDMA clients access to an export.

da08143b85 vlan: more careful checksum features handling
When combining real_dev's features and vlan_features, simple
bitwise AND is used. This doesn't work well for checksum
offloading features as if one set has NETIF_F_HW_CSUM and the
other NETIF_F_IP_CSUM and/or NETIF_F_IPV6_CSUM, we end up with
no checksum offloading. However, from the logical point of view
(how can_checksum_protocol() works), NETIF_F_HW_CSUM contains
the functionality of NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM so
that the result should be IP/IPV6.

Add helper function netdev_intersect_features() implementing
this logic and use it in vlan_dev_fix_features().

Pablo Neira Ayuso says:

====================
Netfilter/nftables updates for net-next

The following patchset contains Netfilter/nftables updates for net-next,
most relevantly they are:

1) Add set element update notification via netlink, from Arturo Borrero.

2) Put all object updates in one single message batch that is sent to
   kernel-space. Before this patch only rules where included in the batch.
   This series also introduces the generic transaction infrastructure so
   updates to all objects (tables, chains, rules and sets) are applied in
   an all-or-nothing fashion, these series from me.

3) Defer release of objects via call_rcu to reduce the time required to
   commit changes. The assumption is that all objects are destroyed in
   reverse order to ensure that dependencies betweem them are fulfilled
   (ie. rules and sets are destroyed first, then chains, and finally
   tables).

4) Allow to match by bridge port name, from Tomasz Bursztyka. This series
   include two patches to prepare this new feature.

5) Implement the proper set selection based on the characteristics of the
   data. The new infrastructure also allows you to specify your preferences
   in terms of memory and computational complexity so the underlying set
   type is also selected according to your needs, from Patrick McHardy.

6) Several cleanup patches for nft expressions, including one minor possible
   compilation breakage due to missing mark support, also from Patrick.

ca8a226343 tcp: make cwnd-limited checks measurement-based, and gentler
Experience with the recent e114a710aa ("tcp: fix cwnd limited
checking to improve congestion control") has shown that there are
common cases where that commit can cause cwnd to be much larger than
necessary. This leads to TSO autosizing cooking skbs that are too
large, among other things.

The main problems seemed to be:

(1) That commit attempted to predict the future behavior of the
connection by looking at the write queue (if TSO or TSQ limit
sending). That prediction sometimes overestimated future outstanding
packets.

(2) That commit always allowed cwnd to grow to twice the number of
outstanding packets (even in congestion avoidance, where this is not
needed).

This commit improves both of these, by:

(1) Switching to a measurement-based approach where we explicitly
track the largest number of packets in flight during the past window
("max_packets_out"), and remember whether we were cwnd-limited at the
moment we finished sending that flight.

(2) Only allowing cwnd to grow to twice the number of outstanding
packets ("max_packets_out") in slow start. In congestion avoidance
mode we now only allow cwnd to grow if it was fully utilized.

Rather than reading back the timing information from the registers,
cache it locally.  This allows implementations to translate the UHS
timing by overriding the set_uhs_signaling() method as required
without also having to emulate the SDHCI_HOST_CONTROL2 register.

781e989cf5 mmc: sdhci: convert to new SDIO IRQ handling
Use a generic threaded interrupt handler for SDIO interrupt handling,
rather than allowing the SDIO core code to buggily spawn its own
thread.  This results in host drivers to be more in control of how
SDIO interrupts are acknowledged in the hardware, rather than having
the internals of the SDIO core placed upon them, possibly resulting
in sub-standard handling.

At least one SDHCI implementation specifies a very specific sequence
to deal with a card interrupt.

bf3b5ec66b mmc: sdio_irq: rework sdio irq handling
Rather than the SDIO support spawning it's own thread for handling card
interrupts, use the generic IRQ infrastructure for this, triggering it
from the host interface's interrupt handling directly.

This avoids a race between the parent thread waiting to receive an
interrupt response from the card, and the slow startup from the sdio
irq thread, which can occur as a result of high system load (eg, while
udev is running.)

          This was posted to LKML at https://lkml.org/lkml/2014/5/13/854.

  5.      Patch to suppress RCU stall warnings while sysrq requests are

          that Rik posted to LKML at https://lkml.org/lkml/2014/4/29/457.
          The reason for pushing this patch ahead instead of waiting until
          3.17 is that the NMI-based stack traces are messing up sysrq
          output, and in some cases also messing up the system as well."

The following parameters are no longer needed by the edma driver since the
information can be obtained from the IP's CCCFG register:
n_channel, n_region, n_slot and n_tc.
Remove the n_cc as well since in this context it has no meaning. We have
separate edma_soc_info struct/eDMA3_CC instance so this member does not
make any sense (and the driver no longer uses it).

Currently, hid-rmi drives every Synaptics product, but the touchscreens
on the Windows tablets should be handled through hid-multitouch.

Instead of providing a long list of PIDs, rely on the scan_report
capability to detect which should go to hid-multitouch, and which
should not go to hid-rmi.

67af981153 cfg80211: allow RSSI compensation
Channels in 2.4GHz band overlap, this means that if we
send a probe request on channel 1 and then move to channel
2, we will hear the probe response on channel 2. In this
case, the RSSI will be lower than if we had heard it on
the channel on which it was sent (1 in this case).

The firmware / low level driver can parse the channel in
the DS IE or HT IE and compensate the RSSI so that it will
still have a valid value even if we heard the frame on an
adjacent channel. This can be done up to a certain offset.

Add this offset as a configuration for the low level driver.
A low level driver that can compensate the low RSSI in this
case should assign the maximal offset for which the RSSI
value is still valid.
