3dd03e52a4 net/fsl_pq_mdio: check TBI address for consistency with mapped range
When configuring the MDIO subsystem it is also necessary to configure
the TBI register. Make sure the TBI is contained within the mapped
register range in order to:
a) make sure the address is computed correctly
b) make users aware that we're actually accessing that register

In case of error, print a message but continue anyway.

f9468e8dc8 bnx2x: Prevent UDP 4-tuple configurations on older adapters
Configuring 4-tuple RSS hsahing for UDP
[E.g., by using `ethtool -N <interface> rx-flow-hash udp4 sdfn']
on a 57710/57711 adapter would cause it to assert as HW does not
support such a configuration.

bee1f753bf mlxsw: Fix bug in __mlxsw_item_bit_array_offset
When calculating the shift needed in order to access a bit array element
in a byte, we should multiply the index by the element size and not
assume it is fixed at 2-bits.

it forgot to set the GSO_GRE flag, causing lots of retransmits.

This fixes generic GRE traffic (like a tunnel added like below)

it gets 8.7Gb/s.

If asix_rx_fixup_internal() fails to allocate rx->ax_skb, it will return
but not clear rx->size. rx points to driver private data. A later call
assumes that nonzero size means ax_skb was allocated and passes a null
ax_skb to skb_put. Changed allocation failure return to clear size first.

e6740165b8 ppp: don't override sk->sk_state in pppoe_flush_dev()
Since commit 2b018d57ff ("pppoe: drop PPPOX_ZOMBIEs in pppoe_release"),
pppoe_release() calls dev_put(po->pppoe_dev) if sk is in the
PPPOX_ZOMBIE state. But pppoe_flush_dev() can set sk->sk_state to
PPPOX_ZOMBIE _and_ reset po->pppoe_dev to NULL. This leads to the
following oops:

pppoe_flush_dev() has no reason to override sk->sk_state with

PPPOX_DEAD, which is the correct state given that sk is unbound and
po->pppoe_dev is NULL.

23860f103b net/mlx4: Handle return codes in mlx4_qp_attach_common
Both new_steering_entry() and existing_steering_entry() return values
based on their success or failure, but currently they fall through
silently.  This can make troubleshooting difficult, as we were unable
to tell which one of these two functions returned errors or
specifically what code was returned.  This patch remedies that
situation by passing the return codes to err, which is returned by
mlx4_qp_attach_common() itself.

This also addresses a leak in the call to mlx4_bitmap_free() as well.

If available PEBs are not enough when initializing volumes, return -ENOSPC
directly. If available PEBs are not enough when initializing WL, return
-ENOSPC instead of -ENOMEM.

fd546ee6a7 mmc: pxamci: fix card detect with slot-gpio API
Move pxamci to mmc slot-gpio API to fix interrupt request.

It fixes the case where the card detection is on a gpio expander, on I2C
for example on zylonite board. In this case, the card detect netsted
interrupt is called from a threaded interrupt. The request_irq() fails,
because a hard irq cannot be a nested interrupt from a threaded
interrupt (set __setup_irq()).

This was tested on zylonite and mioa701 boards.

51424b2860 mmc: sunxi: Fix clk-delay settings
In recent allwinner kernel sources the mmc clk-delay settings have been
slightly tweaked, and for sun9i they are completely different then what
we are using.

This commit brings us in sync with what allwinner does, fixing problems
accessing sdcards on some A33 devices (and likely others).

For pre sun9i hardware this makes the following changes:
-At 400Khz change the sample delay from 7 to 0 (introduced in A31 sdk)
-At 50 Mhz change the sample delay from 5 to 4 (introduced in A23 sdk)

This also drops the clk-delay calculation for clocks > 50 MHz, we do
not need this as we've: mmc->f_max = 50000000, and the delays in the
old code were not correct (at 100 MHz the delay must be a multiple of 60,
at 200 MHz a multiple of 120).

43934ece2e mmc: core: Don't return an error for CD/WP GPIOs when GPIOLIB is unset
When CONFIG_GPIOLIB is unset, its stubs will return -ENOSYS. That means
when the mmc core parses DT for CD/WP GPIOs via mmc_of_parse(), -ENOSYS
becomes propagated to the caller. Typically this means that the mmc host
driver fails to probe.

As the CD/WP GPIOs are already treated as optional, let's extend that to
cover the case when CONFIG_GPIOLIB is unset.

661dfc65f7 net/ibm/emac: bump version numbers for correct work with ethtool
The size of the MAC register dump used to be the size specified by the
reg property in the device tree.  Userland has no good way of finding
out that size, and it was not specified consistently for each MAC type,
so ethtool would end up printing junk at the end of the register dump
if the device tree didn't match the size it assumed.

Using the new version numbers indicates unambiguously that the size of
the MAC register dump is dependent only on the MAC type.

43ae93a93e i40e/i40evf: check for stopped admin queue
It's possible that while we are waiting for the spinlock, another
entity (that owns the spinlock) has shut down the admin queue.
If we then attempt to use the queue, we will panic.

Add a check for this condition on the receive side. This matches
an existing check on the send queue side.

898e6861ff watchdog: bcm2835: Fix poweroff behaviour
Currently poweroff/halt results in a reboot on the Raspberry Pi.
The firmware uses the RSTS register to know which partiton to
boot from. The partiton value is spread into bits
0, 2, 4, 6, 8, 10. Partiton 63 is a special partition used by
the firmware to indicate halt.

The firmware made this change in 19 Aug 2013 and was matched
by the downstream commit:
