In kernel late init, it turns off all unused clocks, which
needs to access subsystem registers such as VENC and VENC_LT.
Accessing MT8173 VENC registers needs two top clocks, mm_sel and
venc_sel. Accessing VENC_LT registers needs mm_sel and venclt_sel.
So we need to keep these clocks on before accessing their registers.
This patch keeps venc_sel / venclt_sel clock on when
VENC / VENC_LT's power is on, to prevent system hang up while
accessing its registeres.

In commit 6e498158a8 ("tipc: move link synch and failover to link aggregation level")
we introduced a new mechanism for performing link failover and
synchronization. We have now detected a bug in this mechanism.
During link synchronization we use the arrival of any packet on
the tunnel link to trig a check for whether it has reached the
synchronization point or not. This has turned out to be too
permissive, since it may cause an arriving non-last SYNCH packet to
end the synch state, just to see the next SYNCH packet initiate a
new synch state with a new, higher synch point. This is not fatal,
but should be avoided, because it may significantly extend the
synchronization period, while at the same time we are not allowed
to send NACKs if packets are lost. In the worst case, a low-traffic
user may see its traffic stall until a LINK_PROTOCOL state message
trigs the link to leave synchronization state.
At the same time, LINK_PROTOCOL packets which happen to have a (non-
valid) sequence number lower than the tunnel link's rcv_nxt value will
be consistently dropped, and will never be able to resolve the situation
described above.
We fix this by exempting LINK_PROTOCOL packets from the sequence number
check, as they should be. We also reduce (but don't completely
eliminate) the risk of entering multiple synchronization states by only
allowing the (logically) first SYNCH packet to initiate a synchronization
state. This works independently of actual packet arrival order.
Fixes: commit 6e498158a8 ("tipc: move link synch and failover to link aggregation level")

Revert the commit e2ca690b65 ("ipv4/icmp: redirect messages
can use the ingress daddr as source"), which tried to introduce a more
suitable behaviour for ICMP redirect messages generated by VRRP routers.
However RFC 5798 section 8.1.1 states:
The IPv4 source address of an ICMP redirect should be the address
that the end-host used when making its next-hop routing decision.
while said commit used the generating packet destination
address, which do not match the above and in most cases leads to
no redirect packets to be generated.

For Qt 5, to be future-proof with the future direction notice appearing
in the 5.5 release, C++11 support is automatically enabled.

Intel Wired LAN Driver Updates 2015-10-13
This series contains updates to i40e, i40evf, ixgbe and fm10k.
Carolyn cleans up ndo_bridge_getlink() by flagging a parameter as
__always_unused, since it is never used. Adds a member to the nvm_info
struct to store OEM version info to be output either by OID or ethtool.
Neerav cleans up a remaining bit shift to use BIT() macro.
Mitch fixes the i40evf driver to properly handle calls to its
ndo_set_mac_address() method. It did not properly check to see if the
override would be allowed by the PF driver, and it never removed the old
address from its filter list. Cleaned up the use of
i40e_enable_vf_mappings() in i40e_alloc_vfs(), since it is just redundant
since we already call it by i40e_reset_vf(). Fixed a possible panic
in some circumstances where the firmware may fail to allocate a VSI for
a VF by checking the return value from i40e_alloc_vf_res() and don't
try to configure the device further if it failed.
Greg fixes the parsing of CEE App TLVs so the caller does not have to
consider whether the App came from a CEE or IEEE DCBx negotiation.
Shannon moves the device ids into a standalone file due to the desire
to write user-land drivers (and other requests) without needing the rest
of the include files.
Catherine adds the ability to save the module information from
get_phy_capabilities() to be used to determine which speeds the module
supports. Also cleaned up the PHY structure by removing unused members
and add the ability to store the PHY capabilities reported by the
firmware.
Emil modifies ixgbe to ensure that flow control packets initiated by the
VF are dropped and reported as spoofed.
Jacob cleans up the fm10k driver to avoid buffer overflow by using
sprintf(), so convert to using snprintf(). Also fixed the use of an
enum as a boolean, so check for the actual value of NETREG_UNINITIALIZED
in case it ever changes from the current value of zero.
v2: Dropped patch 11 of the original series, which added functions that
were never used.

The SMMU architecture defines two different behaviors when 64-bit
registers are written with 32-bit writes. The first behavior causes
zero extension into the upper 32-bits. The second behavior splits a
64-bit register into "normal" 32-bit register pairs.
On some buggy implementations, registers incorrectly zero extended
when they should instead behave as normal 32-bit register pairs.

The DSP MMUs on DRA7xx SoC requires configuring an additional
MMU_CONFIG register present in the DSP_SYSTEM sub module. This
setting dictates whether the DSP Core's MDMA and EDMA traffic
is routed through the respective MMU or not. Add the support
to the OMAP iommu driver so that the traffic is not bypassed
when enabling the MMUs.
The MMU_CONFIG register has two different bits for enabling
each of these two MMUs present in the DSP processor sub-system
on DRA7xx. An id field is added to the OMAP iommu object to
identify and enable each IOMMU. The id information and the
DSP_SYSTEM.MMU_CONFIG register programming is achieved through
the processing of the optional "ti,syscon-mmuconfig" property.
A proper value is assigned to the id field only when this
property is present.
