Pull ARM SoC fixes from Olof Johansson:
"Our first real batch of fixes this release cycle. Nothing really
concerning, and diffstat is a bit inflated due to some DT contents
moving around on STi platforms.
There's a collection of them here:
- A fixup for a build breakage that hits on arm64 allmodconfig in
QCOM SCM firmware drivers
- MMC fixes for OMAP that had quite a bit of breakage this merge
window.
- Misc build/warning fixes on PXA and OMAP
- A couple of minor fixes for Beagleboard X15 which is now starting
to see a few more users in the wild"

Jiri Benc says:
====================
vxlan: support both IPv4 and IPv6 sockets
Note: this needs net merged into net-next in order to apply.
It's currently not easy enough to work with metadata based vxlan tunnels. In
particular, it's necessary to create separate network interfaces for IPv4
and IPv6 tunneling. Assigning an IPv6 address to an IPv4 interface is
allowed yet won't do what's expected. With route based tunneling, one has to
pay attention to use the vxlan interface opened with the correct family.
Other users of this (openvswitch) would need to always create two vxlan
interfaces.
Furthermore, there's no sane API for creating an IPv6 vxlan metadata based
interface.
This patchset simplifies this by opening both IPv4 and IPv6 socket if the
vxlan interface has the metadata flag (IFLA_VXLAN_COLLECT_METADATA) set.
Assignment of addresses etc. works as expected after this.
====================

For metadata based vxlan interface, open both IPv4 and IPv6 socket. This is
much more user friendly: it's not necessary to create two vxlan interfaces
and pay attention to using the right one in routing rules.

Make vxlan_sock_add both alloc the socket and attach it to vxlan_dev. Let
vxlan_sock_release accept vxlan_dev as its parameter instead of vxlan_sock.
This makes vxlan_sock_add and vxlan_sock release complementary. It reduces
code duplication in the next patch.

When fixing the TSO support I noticed we just mask ->gso_size with the
MSSMask value and don't care about the consequences.
Provide a .ndo_features_check() method which drops the NETIF_F_TSO
feature for any skb which would exceed the maximum, and thus forces it
to be segmented by software.
Then we can stop the masking in cp_start_xmit(), and just WARN if the
maximum is exceeded, which should now never happen.
Finally, Francois Romieu noticed that we didn't even have the right
value for MSSMask anyway; it should be 0x7ff (11 bits) not 0xfff.

On a Skylake with 1500MHz base frequency,
the TSC runs at 1512MHz.
This is because the TSC is no longer in the n*100 MHz BCLK domain,
but is now in the m*24MHz crystal clock domain. (24 MHz * 63 = 1512 MHz)
This adds error to several calculations in turbostat,
unless the TSC sample sizes are adjusted for this difference.
Note that calculations in the time domain are immune
from this issue, as the timing sub-system has already
calibrated the TSC against a known wall clock.
AVG_MHz = APERF_delta/measurement_interval
need no adjustment. APERF_delta is in the BCLK domain,
and measurement_interval is in the time domain.
TSC_MHz = TSC_delta/measurement_interval
needs no adjustment -- as we really do want to report
the actual measured TSC delta here, and measurement_interval
is in the accurate time domain.
%Busy = MPERF_delta/TSC_delta
needs adjustment to use TSC_BCLK_DOMAIN_delta.
TSC_BCLK_DOMAIN_delta = TSC_delta * base_hz / tsc_hz
Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/measurement_interval
need adjustment as above.
No other metrics in turbostat need to be adjusted.
Before:
CPU Avg_MHz %Busy Bzy_MHz TSC_MHz
- 550 24.84 2216 1512
0 2191 98.73 2219 1514
2 0 0.01 2130 1512
1 9 0.43 2016 1512
3 2 0.08 2016 1512
After:
CPU Avg_MHz %Busy Bzy_MHz TSC_MHz
- 550 25.05 2198 1512
0 2190 99.62 2199 1512
2 0 0.01 2152 1512
1 9 0.46 2000 1512
3 2 0.10 2000 1512
Note that in this example, the "Before" Bzy_MHz
was reported as exceeding the 2200 max turbo rate.
Also, even a pinned spin loop would not be reported
as over 99% busy.

KNL increments APERF and MPERF every 1024 clocks.
This is compliant with the architecture specification,
which requires that only the ratio of APERF/MPERF need be valid.
However, turbostat takes advantage of the fact that these
two MSRs increment every un-halted clock
at the actual and base frequency:
AVG_MHz = APERF_delta/measurement_interval
%Busy = MPERF_delta/TSC_delta
This quirk is needed for these calculations to also work on KNL,
which would otherwise show a value 1024x smaller than expected.

Prior to the VRF change the oif was not set in the flow struct, so the
VRF support should really have only added the vrf_master_ifindex lookup.

When performing sendonly joins, we queue the packets that trigger
the join until the join completes. This may take on the order of
hundreds of milliseconds. It is easy to have many more than three
packets come in during that time. Expand the maximum queue depth
in order to try and prevent dropped packets during the time it
takes to join the multicast group.

Avoid IRQs occupied by ISA IRQs when allocating IRQs for PCI link devices,
otherwise it may cause interrupt storm due to incompatible pin attributes.
This issue was triggered on a KVM virtual machine, which
1) uses IRQ9 for SCI in high level mode.
2) defines an PCI interrupt link device (LNKS) with IRQ9 as the only
possible irq.
3) has an PCI device referring to link device LNKS.
So it causes interrupt storm when enabling the PCI device because PCI IRQ
works in low level mode.

When query handler is not found, "result" is actually stil 0, and
"struct acpi_ec_query" is not NULL, so the deletion code of
"struct acpi_ec_query" at the end of the function cannot be invoked.
As a consequence, memory leak can be observed.
The issue is introduced by this commit:

disable it on them. This is enough to make the regressions go away

dccp/tcp: constify listener sock
Another patch bomb to prepare lockless TCP/DCCP LISTEN handling.
SYNACK retransmits are built and sent without listener socket
being locked. Soon, initial SYNACK packets will have same property.
This series makes sure we did not something wrong with this model,
by adding a const qualifier in all the paths taken from synack building
and transmit, for IPv4/IPv6 and TCP/dccp.
The only potential problem was the rewrite of ecn bits for connections
with DCTCP as congestion module, but this was a very minor one.

or fastopen sockets. Mark socket as const to catch future changes
that might break the assumption.

Like tcp_make_synack() the only time we might change the socket is
when calling sock_wmalloc(), which is using atomic operation to
update sk->sk_wmem_alloc
Also use MAX_DCCP_HEADER as both IPv4/IPv6 use this value for max_header.

This is to document that socket lock might not be held at this point.
skb_set_owner_w() and ipv6_local_error() are using proper atomic ops
or spinlocks, so we promote the socket to non const when calling them.
netfilter hooks should never assume socket lock is held,
we also promote the socket to non const.

listener socket is not locked when tcp_make_synack() is called.
We better make sure no field is written.
There is one exception : Since SYNACK packets are attached to the listener
at this moment (or SYN_RECV child in case of Fast Open),
sock_wmalloc() needs to update sk->sk_wmem_alloc, but this is done using
atomic operations so this is safe.

SYNACK packets might be sent without holding socket lock.
For DCTCP/ECN sake, we should call INET_ECN_xmit() while
socket lock is owned, and only when we init/change congestion control.
This also fixies a bug if congestion module is changed from
dctcp to another one on a listener : we now clear ECN bits
properly.

This function is used to build and send SYNACK packets,
