VGA input
Added support for YCrCb analog input.
If input is ADV7842_MODE_RGB and RGB quantization range is set to
V4L2_DV_RGB_RANGE_AUTO, then video with CEA timings will be received
as RGB. For ADV7842_MODE_COMP, automatic CSC mode will be selected.
See table 48 on page 281 in "ADV7842 Hardware Manual, Rev. 0, January 2011"
for details.
Make sure that when switching inputs the RGB quantization range is
updated as well.
Also updated the platform_data in ezkit to ensure that what was the old
default value is now explicitly specified, so the behavior for that board
is unchanged.

====================
[GIT net-next] Open vSwitch
Open vSwitch changes for net-next/3.14. Highlights are:
* Performance improvements in the mechanism to get packets to userspace
using memory mapped netlink and skb zero copy where appropriate.
* Per-cpu flow stats in situations where flows are likely to be shared
across CPUs. Standard flow stats are used in other situations to save
memory and allocation time.
* A handful of code cleanups and rationalization.

Proportional Integral controller Enhanced (PIE) is a scheduler to address the
bufferbloat problem.
>From the IETF draft below:
" Bufferbloat is a phenomenon where excess buffers in the network cause high
latency and jitter. As more and more interactive applications (e.g. voice over
IP, real time video streaming and financial transactions) run in the Internet,
high latency and jitter degrade application performance. There is a pressing
need to design intelligent queue management schemes that can control latency and
jitter; and hence provide desirable quality of service to users.
We present here a lightweight design, PIE(Proportional Integral controller
Enhanced) that can effectively control the average queueing latency to a target
value. Simulation results, theoretical analysis and Linux testbed results have
shown that PIE can ensure low latency and achieve high link utilization under
various congestion situations. The design does not require per-packet
timestamp, so it incurs very small overhead and is simple enough to implement
in both hardware and software. "
Many thanks to Dave Taht for extensive feedback, reviews, testing and
suggestions. Thanks also to Stephen Hemminger and Eric Dumazet for reviews and
suggestions. Naeem Khademi and Dave Taht independently contributed to ECN
support.

PVH allows PV linux guest to utilize hardware extended capabilities,
such as running MMU updates in a HVM container.
The Xen side defines PVH as (from docs/misc/pvh-readme.txt,
with modifications):
"* the guest uses auto translate:
- p2m is managed by Xen
- pagetables are owned by the guest
- mmu_update hypercall not available
* it uses event callback and not vlapic emulation,
* IDT is native, so set_trap_table hcall is also N/A for a PVH guest.
For a full list of hcalls supported for PVH, see pvh_hypercall64_table
in arch/x86/hvm/hvm.c in xen. From the ABI prespective, it's mostly a
PV guest with auto translate, although it does use hvm_op for setting
callback vector."
Use .ascii and .asciz to define xen feature string. Note, the PVH
string must be in a single line (not multiple lines with \) to keep the
assembler from putting null char after each string before \.
This patch allows it to be configured and enabled.
We also use introduce the 'XEN_ELFNOTE_SUPPORTED_FEATURES' ELF note to
tell the hypervisor that 'hvm_callback_vector' is what the kernel
needs. We can not put it in 'XEN_ELFNOTE_FEATURES' as older hypervisor
parse fields they don't understand as errors and refuse to load
the kernel. This work-around fixes the problem.

The 'xen_hvm_resume_frames' used to be an 'unsigned long'
and contain the virtual address of the grants. That was OK
for most architectures (PVHVM, ARM) were the grants are contiguous
in memory. That however is not the case for PVH - in which case
we will have to do a lookup for each virtual address for the PFN.
Instead of doing that, lets make it a structure which will contain
the array of PFNs, the virtual address and the count of said PFNs.
Also provide a generic functions: gnttab_setup_auto_xlat_frames and
gnttab_free_auto_xlat_frames to populate said structure with
appropriate values for PVHVM and ARM.
To round it off, change the name from 'xen_hvm_resume_frames' to
a more descriptive one - 'xen_auto_xlat_grant_frames'.
For PVH, in patch "xen/pvh: Piggyback on PVHVM for grant driver"
we will populate the 'xen_auto_xlat_grant_frames' by ourselves.
v2 moves the xen_remap in the gnttab_setup_auto_xlat_frames
and also introduces xen_unmap for gnttab_free_auto_xlat_frames.

Which is a PV guest with auto page translation enabled
and with vector callback. It is a cross between PVHVM and PV.
The Xen side defines PVH as (from docs/misc/pvh-readme.txt,
with modifications):
"* the guest uses auto translate:
- p2m is managed by Xen
- pagetables are owned by the guest
- mmu_update hypercall not available
* it uses event callback and not vlapic emulation,
* IDT is native, so set_trap_table hcall is also N/A for a PVH guest.
For a full list of hcalls supported for PVH, see pvh_hypercall64_table
in arch/x86/hvm/hvm.c in xen. From the ABI prespective, it's mostly a
PV guest with auto translate, although it does use hvm_op for setting
callback vector."
Also we use the PV cpuid, albeit we can use the HVM (native) cpuid.
However, we do have a fair bit of filtering in the xen_cpuid and
we can piggyback on that until the hypervisor/toolstack filters
the appropiate cpuids. Once that is done we can swap over to
use the native one.
We setup a Kconfig entry that is disabled by default and
cannot be enabled.
Note that on ARM the concept of PVH is non-existent. As Ian
put it: "an ARM guest is neither PV nor HVM nor PVHVM.
It's a bit like PVH but is different also (it's further towards
the H end of the spectrum than even PVH).". As such these
options (PVHVM, PVH) are never enabled nor seen on ARM
compilations.

Add the hypercall sub-ops and the structures for the shared data used
in the FIFO-based event channel ABI.
The design document for this new ABI is available here:
http://xenbits.xen.org/people/dvrabel/event-channels-H.pdf
In summary, events are reported using a per-domain shared event array
of event words. Each event word has PENDING, LINKED and MASKED bits
and a LINK field for pointing to the next event in the event queue.
There are 16 event queues (with different priorities) per-VCPU.
Key advantages of this new ABI include:
- Support for over 100,000 events (2^17).
- 16 different event priorities.
- Improved fairness in event latency through the use of FIFOs.
The ABI is available in Xen 4.4 and later.

Sometimes boot loaders set CPU frequency to a value outside of frequency table
present with cpufreq core. In such cases CPU might be unstable if it has to run
on that frequency for long duration of time and so its better to set it to a
frequency which is specified in freq-table. This also makes cpufreq stats
inconsistent as cpufreq-stats would fail to register because current frequency
of CPU isn't found in freq-table.
Because we don't want this change to affect boot process badly, we go for the
next freq which is >= policy->cur ('cur' must be set by now, otherwise we will
end up setting freq to lowest of the table as 'cur' is initialized to zero).
In case current frequency doesn't match any frequency from freq-table, we throw
warnings to user, so that user can get this fixed in their bootloaders or
freq-tables.

present with cpufreq core. In such cases CPU might be unstable if it has to run
on that frequency for long duration of time and so its better to set it to a
frequency which is specified in frequency table.
On some systems we can't really say what frequency we're running at the moment
and so for these we shouldn't check if we are running at a frequency present in
frequency table. And so we really can't force this for all the cpufreq drivers.
Hence we are created another flag here: CPUFREQ_NEED_INITIAL_FREQ_CHECK that
will be marked by platforms which want to go for this check at boot time.
Initially this is done for all ARM platforms but others may follow if required.

====================
netfilter/IPVS updates for net-next
The following patchset contains Netfilter updates for your net-next tree,
they are:
* Add full port randomization support. Some crazy researchers found a way
to reconstruct the secure ephemeral ports that are allocated in random mode
by sending off-path bursts of UDP packets to overrun the socket buffer of
the DNS resolver to trigger retransmissions, then if the timing for the
DNS resolution done by a client is larger than usual, then they conclude
that the port that received the burst of UDP packets is the one that was
opened. It seems a bit aggressive method to me but it seems to work for
them. As a result, Daniel Borkmann and Hannes Frederic Sowa came up with a
new NAT mode to fully randomize ports using prandom.
* Add a new classifier to x_tables based on the socket net_cls set via
cgroups. These includes two patches to prepare the field as requested by
Zefan Li. Also from Daniel Borkmann.
* Use prandom instead of get_random_bytes in several locations of the

ASoC: Updates for v3.14
Not a lot going on framework wise, partly due to Christmas at least in
the case of the work I've been doing, but there's been quite a lot of
cleanup activity going on and the usual trickle of new drivers:
- Update to the generic DMA code to support deferred probe and managed
resources.
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs.
- Device tree support for the simple card, max98090 and cs42l52.
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more modern
and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi.
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi.

I have no objections to reverting it. There were concerns from
Al Viro that it'd be tough to get right by callers and I had
assumed it got dropped after that. I had planned on using it in
my btrfs sysfs exports patchset but came up with a better way.

This function is used to get a specific core when there is more than
one core of that specific type. This is used in bgmac to reset all GMAC
cores.

They are same, so unify them as one; since macvlan is a kind of vlan,
vlan_pcpu_stats should be a proper name for vlan and macvlan.

They are same, so unify them as one, pcpu_sw_netstats.
Define pcpu_sw_netstat in netdevice.h, remove pcpu_tstats
from if_tunnel and remove br_cpu_netstats from br_private.h

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates
This series contains updates to i40e and pci_regs.h.
Anjali provides a patch to prevent messages from stray HMC events, except
at interrupt message level, and refactors the HMC error handling.
Catherine adds routines in probe to populate/check PCI bus speed and width,
then verify we are in a 8GT/s x8 PCIe slot and warn when we are not.
Shannon adds Wake-on-LAN support for i40e, fixes curly brace use as well as
return type for i40e_vsi_clear_rings().
Joseph implements receive offload for VXLAN for i40e, where the hardware
supports checksum offload/verification of the inner/outer header.
Mitch provides the bulk of the changes, where he refactors the VF reset
code so that it works on real hardware. Then does code cleanup by
calling existing functions to enable and disable queues for VFs and
remove unused functions. Removes a unnecessary log messages that are
seen at every VF reset, for example complaining about disabling queues
that are already disabled. Fixes an error return when the VF asks to
add an invalid MAC address and if the VF sends a bad message, make it
more informative about what is actually going on.
Jesse refactors the LED function to flash LED lights correctly.
v2:
- removed patch 5 "i40e: add set settings and pauseparam" based on
feedback from Ben Hutchings, will re-work that patch for later
submission
- Added patch "i40e: Implementation of vxlan ndo's" from Joseph to
address Or Gerlitz's questions and concerns. This patch adds the
implementation for the VXLAN ndo's and allows the hardware to do
receive checksum offload for inner packets on the UDP ports that
VXLAN notifies us about.
- Added patch "i40e: using for_each_set_bit to simplify the code"
from Wei Yongjun. This patch uses for_each_set_bit() to simply
the code.
v3:
- fixed indentation issue in patch 11 based on feedback from
Sergei Shtylyov.
Sorry for the delayed release of v4, it was delayed to the holidays.
v4:
- Addressed Or Gerlitz's concerns about trying to get a hold of a mutex
while holding a spin lock in patch 6 by executing the AQ commands from
a subtask.
- Addressed David Miller's Kconfig concerns by creating a Kconfig VXLAN
option for i40e and wrapped appropriate code with the config option in
patch 6.
- Updated patch 7 based on the changes made in patch 6 in the above two
bullets.
v5:
- Added the patch to pci_regs.h based on David Miller's feedback to add
PCI defines for speed and width
- Updated patch 3 description to better explain the changes based on
feedback from David Miller
- Updated patch 4 to use the newly added defines to pci_regs.h instead
of local defines
- Updated patch 7 to use <net/vxlan.h> in the #include based on feedback
from David Miller

phy_scan_fixups() isn't and shouldn't be called by the drivers directly, so
unexport it. And since Florian Fainelli's recent patches, the function is only
called locally, so we can make it static as well.

Remove adjust_state() callback from 'struct phy_device' since it seems to have
never been really used from the inception: phy_start_machine() has been always
called with 2nd argument equal to NULL.
