David Gibson 4fce14820c ibmveth: Fix off-by-one error in ibmveth_change_mtu()
AFAIK the PAPR document which defines the virtual device interface used by
the ibmveth driver doesn't specify a specific maximum MTU.  So, in the
ibmveth driver, the maximum allowed MTU is determined by the maximum
allocated buffer size of 64k (corresponding to one page in the common case)
minus the per-buffer overhead IBMVETH_BUFF_OH (which has value 22 for 14
bytes of ethernet header, plus 8 bytes for an opaque handle).

This suggests a maximum allowable MTU of 65514 bytes, but in fact the
driver only permits a maximum MTU of 65513.  This is because there is a <
instead of an <= in ibmveth_change_mtu(), which only permits an MTU which
is strictly smaller than the buffer size, rather than allowing the buffer
to be completely filled.

This patch fixes the buglet.

In 02c958dd3 (net/macb: add TX multiqueue support for gem), the
initialization of tx_head and tx_tail in macb_init_rings() was moved

tx_head and tx_tail only need to be assigned once, move them back out of
the loop.

Yuval Mintz 909d9faae2 bnx2x: Prevent inner-reload while VFs exist
On some feature changes, driver employes an inner-reload flow where it
resets the function and re-configures it with the new required set of
parameters.

Such a flow proves fatal to any VF since those were not intended to be used
while HW is being reset underneath, causing them [at best] to lose all
connectivity.

This changes driver behavior to fail all configuration changes [e.g., mtu
change] requested of the driver in case VFs are active.

Linus Torvalds 5c73cc4b6c ARM: DT updates for v4.1
As always, this tends to be one of our bigger branches. There are lots of
 updates this release, but not that many jumps out as something that needs
 more detailed coverage. Some of the highlights are:
 
 - DTs for the new Annapurna Labs Alpine platform
 - More graphics DT pieces falling into place on Exynos, bridges, clocks.
 - Plenty of DT updates for Qualcomm platforms for various IP blocks
 - Some churn on Tegra due to switch-over to tool-generated pinctrl data
 - Misc fixes and updates for Atmel at91 platforms
 - Various DT updates to add IP block support on Broadcom's Cygnus platforms
 - More updates for Renesas platforms as DT support is added for various IP
   blocks (IPMMU, display, audio, etc).

Andreas Oetken 71cd26e76a altera tse: Error-Bit on tx-avalon-stream always set.
The Error-Bit on the avalon streaming interface of the
tx-dma-channel was always set. In SGMII configurations
this leads to error-symbols on the PCS and packet-rejection
on the receiver side (e.g. SGMII/1000Base-X connected switch).

This only applies to the tse-configuration with MSGDMA.

This issue was detected and fixed on a custom board with
a direct connection to a Marvell switch in SGMII-PHY-Mode.
(incl. custom patches for SGMII-PCS).

According to the datasheet if ff_tx_err (avalon-streaming)
is set it is forwarded to gm_tx_err. As a result the PCS
is forwarding the error by sending a "/V/"-caracter.

Linus Torvalds 6496edfce9 This is the final removal (after several years!) of the obsolete cpus_*
functions, prompted by their mis-use in staging.
 
 With these function removed, all cpu functions should only iterate to
 nr_cpu_ids, so we finally only allocate that many bits when cpumasks
 are allocated offstack.
 
 Thanks,

Check for (count < limit) before checking the get_rx_status in tse_rx-function.
Function get_rx_status is reading from the response-fifo.
If there is currently a response in the fifo,
reading the last byte of the response pops the value from the fifo.
If the limit is checked as second condition
and the limit is reached the fifo is popped but the packet is not processed.

Johannes Berg 8b86a61da3 net: remove unused 'dev' argument from netif_needs_gso()
In commit 04ffcb255f ("net: Add ndo_gso_check") Tom originally
added the 'dev' argument to be able to call ndo_gso_check().

Then later, when generalizing this in commit 5f35227ea3
("net: Generalize ndo_gso_check to ndo_features_check")
Jesse removed the call to ndo_gso_check() in netif_needs_gso()
by calling the new ndo_features_check() in a different place.
This made the 'dev' argument unused.

Remove the unused argument and go back to the code as before.

Herbert Xu f40ae91307 act_mirred: Fix bogus header when redirecting from VLAN
When you redirect a VLAN device to any device, you end up with
crap in af_packet on the xmit path because hard_header_len is
not equal to skb->mac_len.  So the redirected packet contains
four extra bytes at the start which then gets interpreted as
part of the MAC address.

This patch fixes this by only pushing skb->mac_len.  We also
need to fix ifb because it tries to undo the pushing done by
act_mirred.

Michal Hocko f72f116a2a cxgb4: drop __GFP_NOFAIL allocation
set_filter_wr is requesting __GFP_NOFAIL allocation although it can return
ENOMEM without any problems obviously (t4_l2t_set_switching does that
already).  So the non-failing requirement is too strong without any
obvious reason.  Drop __GFP_NOFAIL and reorganize the code to have the
failure paths easier.

The same applies to _c4iw_write_mem_dma_aligned which uses __GFP_NOFAIL
and then checks the return value and returns -ENOMEM on failure.  This
doesn't make any sense what so ever.  Either the allocation cannot fail or
it can.

del_filter_wr seems to be safe as well because the filter entry is not
marked as pending and the return value is propagated up the stack up to
c4iw_destroy_listen.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2015-04-14

This series contains updates to i40e and i40evf.

Mitch provides a fix for i40e, where VFs were gone and the associated
VSI's had been removed and the rings were not stopped, which in some
circumstances cased memory corruption or DMAR errors.  So stop all the
rings associated with each VF before releasing its resources.  Also
cleaned up a poorly indented piece of code.  Fixes VF link state, where
VF devices were assuming link is up unless told otherwise, which means
that VFs instantiated on a PF with no link, would report the wrong state.

Anjali adds support to add Flow director Sideband rules for a VF from it's
PF.  Fixes a recently discovered hardware issue, where after a VFLR
hardware might be indicating to us a reset completion little too early, so
wait another 10 msec for cache to be cleaned up.

Jesse enables the user to dump the internal hardware state for better
debugging by allowing a bash script to acquire information about the
internal hardware state.  The data output to the kernel log is collected
by the script and can then be sent to Intel.  Also fixed a possible
failure path to allocate memory that was found by smatch.  Cleaned up
unused local variables.

Eric Dumazet 074975d037 bnx2x: Fix busy_poll vs netpoll
Commit 9a2620c877 ("bnx2x: prevent WARN during driver unload")
switched the napi/busy_lock locking mechanism from spin_lock() into
spin_lock_bh(), breaking inter-operability with netconsole, as netpoll
disables interrupts prior to calling our napi mechanism.

This switches the driver into using atomic assignments instead of the
spinlock mechanisms previously employed.

Based on initial patch from Yuval Mintz & Ariel Elior

I basically added softirq starvation avoidance, and mixture
of atomic operations, plain writes and barriers.

Note this slightly reduces the overhead for this driver when no
busy_poll sockets are in use.

Thomas Gleixner 48b63776c8 net: hip04: Make tx coalesce timer actually work
The code sets the expiry value of the timer to a relative value and
starts it with hrtimer_start_expires. That's fine, but that only works
once. The timer is started in relative mode, so the expiry value gets
overwritten with the absolut expiry time (now + expiry).

So once the timer expired, a new call to hrtimer_start_expires results
in an immidiately expired timer, because the expiry value is
already in the past.

Use the proper mechanisms to (re)start the timer in the intended way.

 4) Many ipv4 FIB lookup optimizations from Alexander Duyck.

 5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel

 6) Remove the ugly compat support in ARP for ugly layers like ax25,

 7) Support L3 forwarding offloading in switches, from Scott Feldman.

 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed
    up route lookups even further.  From Alexander Duyck.

 9) Many improvements and bug fixes to the rhashtable implementation,
    from Herbert Xu and Thomas Graf.  In particular, in the case where
    an rhashtable user bulk adds a large number of items into an empty
    table, we expand the table much more sanely.

10) Don't make the tcp_metrics hash table per-namespace, from Eric

11) Extend EBPF to access SKB fields, from Alexei Starovoitov.

12) Split out new connection request sockets so that they can be
    established in the main hash table.  Much less false sharing since
    hash lookups go direct to the request sockets instead of having to

Wei Liu ccc9d90a9a xenbus_client: Extend interface to support multi-page ring
Originally Xen PV drivers only use single-page ring to pass along
information. This might limit the throughput between frontend and
backend.

The patch extends Xenbus driver to support multi-page ring, which in
general should improve throughput if ring is the bottleneck. Changes to
various frontend / backend to adapt to the new interface are also
included.

Affected Xen drivers:
* blkfront/back
* netfront/back
* pcifront/back
* scsifront/back
* vtpmfront

The interface is documented, as before, in xenbus_client.c.

Merge tag 'pm+acpi-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management and ACPI updates from Rafael Wysocki:
 "These are mostly fixes and cleanups all over, although there are a few
  items that sort of fall into the new feature category.

  First off, we have new callbacks for PM domains that should help us to
  handle some issues related to device initialization in a better way.

  There also is some consolidation in the unified device properties API
  area allowing us to use that inferface for accessing data coming from
  platform initialization code in addition to firmware-provided data.

  We have some new device/CPU IDs in a few drivers, support for new
  chips and a new cpufreq driver too.

  Specifics:

   - Generic PM domains support update including new PM domain callbacks
     to handle device initialization better (Russell King, Rafael J
     Wysocki, Kevin Hilman)

   - Unified device properties API update including a new mechanism for

Jesse Brandeburg 3169c323cf i40e: enable user dump of internal hardware state
This is a feature to enable better debugging of user reported issues by
allowing a bash script to acquire information about the internal hardware
state. The data output to the kernel log is collected by the script and can
then be sent to Intel. This is a critical debugging feature for helping us
interpret and reproduce complex customer setups.

Gratuitously notify VFs of link state when they activate their queues.
In general, this is the last thing that a VF driver will do as it opens
its interface, so this is a good time to notify the VF.

Currently, VF devices assume link is up unless told otherwise, which
means that VFs instantiated on a PF with no link will report the wrong
state. This change corrects that issue.
