Pull irq fixes from Thomas Gleixner:
"A slighlty large fix for a subtle issue in the CPU hotplug code of
certain ARM SoCs, where the not yet online cpu needs to setup the cpu
local timer and needs to set the interrupt affinity to itself.
Setting interrupt affinity to a not online cpu is prohibited and
therefor the timer interrupt ends up on the wrong cpu, which leads to
nasty complications.
The SoC folks tried to hack around that in the SoC code in some more
than nasty ways. The proper solution is to have a way to enforce the
affinity setting to a not online cpu. The core patch to the genirq
code provides that facility and the follow up patches make use of it
in the GIC interrupt controller and the exynos timer driver.
The change to the core code has no implications to existing users,
except for the rename of the locked function and therefor the
necessary fixup in mips/cavium. Aside of that, no runtime impact is
possible, as none of the existing interrupt chips implements anything
which depends on the force argument of the irq_set_affinity()
callback"

This patch fixes the PTP Tx timestamp interrupt handler. The original
code misinterpreted the interrupt handler design. We were clearing the
ena_mask bit for the Timesync interrupts. This is done to indicate that
the interrupt will be handled in a scheduled work item (instead of
immediately) and that work item is responsible for re-enabling the
interrupts. However, the Tx timestamp was being handled immediately and
nothing was ever re-enabling it. This resulted in a single interrupt
working for the life of the driver.
This patch fixes the issue by instead clearing the bit from icr0 which
is used to indicate that the interrupt was immediately handled and can
be re-enabled right away. This patch also clears up a related issue due
to writing the PRTTSYN_STAT_0 register, which was unintentionally
clearing the cause bits for Timesync interrupts.

This series of patches addresses a handful of issues found in testing
and reported by users of the Altera Triple Speed Ethernet soft IP.
The patches address the following issues (in summary)
1) The SGDMA soft IP was found to incorrectly process receive packets
when the target physical address of the receive buffer was on
a boundary that's not 32-bit aligned. One of the patches addresses
this issue.
2) The pause quanta was not being set by the driver, one patch of this
series sets the pause quanta to the IEEE defined default value
since the hardware reset value is 0.
3) An issue in a error recovery path of the probe routine caused a
kernel panic in the event a phy was probed and could not be found.
A patch addresses this issue.
4) A change was made to the driver name for Ethtool support, and
comments added to support an addition to Ethtool to support

This patch works around a recently discovered unaligned receive dma problem
with the Altera SGMDA. The Altera SGDMA component cannot be configured to
DMA data to unaligned addresses for receive packet operations from the
Triple Speed Ethernet component because of a potential data transfer
corruption that can occur. This patch addresses this issue by
utilizing the shift 16 bits feature of the Altera Triple Speed Ethernet
component and modifying the receive buffer physical addresses accordingly
such that the target receive DMA address is always aligned on a 32-bit
boundary.

Starting with commit 2dc33bbc "bnx2x: Remove the sriov VFOP mechanism",
the bnx2x started enforcing vlan credits for all vlan configurations.
This exposed 2 issues:
- Vlan credits are not returned once a VF is removed; this causes a leak
of credits, and eventually will lead to VFs with no vlan credits.
- A vlan credit must be set aside for the Hypervisor to use, and should
not be visible to the VF.
Although linux VFs at the moment do not support vlan configuration [from the
VF side] which causes them to be resilient to this sort of issue, Windows VF
over linux hypervisors might fail to load as the vlan credits become depleted.

When removing a VF interface, the driver fails to release that VF's mailbox
and bulletin board allocated memory.

tipc: add support for link state subscriptions
Low level topology information like TIPC link up/down is useful for
applications like teamd to make smarter failover decisions in a
HA cluster environment. Fetching logical link names through an ioctl
may hurt the eyes of some. Suggestions for a more elegant way of doing
this would be appreciated in that case. :)
v2:
-Properly based on net-next
-Off-list comments from Billie Alsup:
-Add a string length parameter to tipc_node_get_linkname
-Use TIPC_MAX_LINK_NAME definition instead of hardcoded
value in tipc_sioc_ln_req linkname

We add a new ioctl for AF_TIPC that can be used to fetch the
logical name for a link to a remote node on a given bearer. This
should be used in combination with link state subscriptions.
The logical name size limit definitions are moved to tipc.h, as
they are now also needed by the new ioctl.

When links are established over a bearer plane, we create a node
local publication containing information about the peer node and
bearer plane. This allows TIPC applications to use the standard
TIPC topology server subscription mechanism to get notifications
when a link goes up or down.

fs_path_ensure_buf is used to make sure our path buffers for
send are big enough for the path names as we construct them.
The buffer size is limited to 32K by the length field in
the struct.
But bugs in the path construction can end up trying to build
a huge buffer, and we'll do invalid memmmoves when the
buffer length field wraps.
This patch is step one, preventing the overflows.

KVM currently crashes and burns on big-endian hosts, so don't allow it
to be selected until we've got that fixed.

The whole IIO subsystem can be built as modules. If you make it a
module then stuff marked as "Y" in the adc directory simply won't be
linked in properly.
The two configs that were wrong were EXYNOS_ADC and LP8788_ADC. I
know for a fact that EXYNOS_ADC will work as a module. I assume
LP8788_ADC will also be fine.
