This patch adds three new RGB media bus formats that describe
18-bit or 24-bit samples transferred over an LVDS bus with three
or four differential data pairs, serialized into 7 time slots,
using standard SPWG/PSWG/VESA or JEIDA data ordering.

Now that the code is in place for KVM to support MIPS SIMD Architecutre
(MSA) in MIPS guests, wire up the new KVM_CAP_MIPS_MSA capability.
For backwards compatibility, the capability must be explicitly enabled
in order to detect or make use of MSA from the guest.
The capability is not supported if the hardware supports MSA vector
partitioning, since the extra support cannot be tested yet and it
extends the state that the userland program would have to save.

While thinking on the whole clock discussion it occurred to me we have
two distinct uses of time:
1) the tracking of event/ctx/cgroup enabled/running/stopped times
which includes the self-monitoring support in struct
perf_event_mmap_page.
2) the actual timestamps visible in the data records.
And we've been conflating them.
The first is all about tracking time deltas, nobody should really care
in what time base that happens, its all relative information, as long
as its internally consistent it works.
The second however is what people are worried about when having to
merge their data with external sources. And here we have the
discussion on MONOTONIC vs MONOTONIC_RAW etc..
Where MONOTONIC is good for correlating between machines (static
offset), MONOTNIC_RAW is required for correlating against a fixed rate
hardware clock.
This means configurability; now 1) makes that hard because it needs to
be internally consistent across groups of unrelated events; which is
why we had to have a global perf_clock().
However, for 2) it doesn't really matter, perf itself doesn't care
what it writes into the buffer.
The below patch makes the distinction between these two cases by
adding perf_event_clock() which is used for the second case. It
further makes this configurable on a per-event basis, but adds a few
sanity checks such that we cannot combine events with different clocks
in confusing ways.
And since we then have per-event configurability we might as well
retain the 'legacy' behaviour as a default.

some data in the middle of file.
FALLOC_FL_INSERT_RANGE will create space for writing new data within
a file after shifting extents to right as given length. This command
also has same limitations as FALLOC_FL_COLLAPSE_RANGE in that
operations need to be filesystem block boundary aligned and cannot
cross the current EOF.

If vlan offloading takes place then vlan header is removed from frame
and its contents, both vlan_tci and vlan_proto, is available to user
space via TPACKET interface. However, only vlan_tci can be used in BPF
filters.
This commit introduces a new BPF extension. It makes possible to load
the value of vlan_proto (vlan TPID) to register A. Support for classic
BPF and eBPF is being added, analogous to skb->protocol.

This patch implements the stable privacy address generation for
link-local and autoconf addresses as specified in RFC7217.
RID = F(Prefix, Net_Iface, Network_ID, DAD_Counter, secret_key)
is the RID (random identifier). As the hash function F we chose one
round of sha1. Prefix will be either the link-local prefix or the
router advertised one. As Net_Iface we use the MAC address of the
device. DAD_Counter and secret_key are implemented as specified.
We don't use Network_ID, as it couples the code too closely to other
subsystems. It is specified as optional in the RFC.
As Net_Iface we only use the MAC address: we simply have no stable
identifier in the kernel we could possibly use: because this code might
run very early, we cannot depend on names, as they might be changed by
user space early on during the boot process.
A new address generation mode is introduced,
IN6_ADDR_GEN_MODE_STABLE_PRIVACY. With iproute2 one can switch back to
none or eui64 address configuration mode although the stable_secret is
already set.
We refuse writes to ipv6/conf/all/stable_secret but only allow
ipv6/conf/default/stable_secret and the interface specific file to be
written to. The default stable_secret is used as the parameter for the
namespace, the interface specific can overwrite the secret, e.g. when
switching a network configuration from one system to another while
inheriting the secret.

While all other pad ops allow you to select whether to use the 'try' or
the 'active' formats, the enum ops didn't have that option and always used
'try'.
However, this will fail if a simple (e.g. PCI) bridge driver wants to use
the enum pad op of a subdev that's also used in a complex platform driver
like the omap3. Such a bridge driver generally wants to enum formats based
on the active format.
So add a new 'which' field to these structs. Note that V4L2_SUBDEV_FORMAT_TRY
is 0, so the default remains TRY (applications need to set reserved to 0).

We send unicast neighbor (ARP or NDP) solicitations ucast_probes
times in PROBE state. Zhu Yanjun reported that some implementation
does not reply against them and the entry will become FAILED, which
is undesirable.
We had been dealt with such nodes by sending multicast probes mcast_
solicit times after unicast probes in PROBE state. In 2003, I made
a change not to send them to improve compatibility with IPv6 NDP.
Let's introduce per-protocol per-interface sysctl knob "mcast_
reprobe" to configure the number of multicast (re)solicitation for
reconfirmation in PROBE state. The default is 0, since we have
been doing so for 10+ years.

This work extends the "classic" BPF programmable tc action by extending
its scope also to native eBPF code!
Together with commit e2e9b6541d ("cls_bpf: add initial eBPF support
for programmable classifiers") this adds the facility to implement fully
flexible classifier and actions for tc that can be implemented in a C
subset in user space, "safely" loaded into the kernel, and being run in
native speed when JITed.
Also, since eBPF maps can be shared between eBPF programs, it offers the
possibility that cls_bpf and act_bpf can share data 1) between themselves
and 2) between user space applications. That means that, f.e. customized
runtime statistics can be collected in user space, but also more importantly
classifier and action behaviour could be altered based on map input from
the user space application.
For the remaining details on the workflow and integration, see the cls_bpf
commit e2e9b6541d. Preliminary iproute2 part can be found under [1].

In order to prepare eBPF support for tc action, we need to add
sched_act_type, so that the eBPF verifier is aware of what helper
function act_bpf may use, that it can load skb data and read out
currently available skb fields.
This is bascially analogous to 96be4325f4 ("ebpf: add sched_cls_type
and map it to sk_filter's verifier ops").
BPF_PROG_TYPE_SCHED_CLS and BPF_PROG_TYPE_SCHED_ACT need to be
separate since both will have a different set of functionality in
future (classifier vs action), thus we won't run into ABI troubles
when the point in time comes to diverge functionality from the
classifier.
The future plan for act_bpf would be that it will be able to write
into skb->data and alter selected fields mirrored in struct __sk_buff.
For an initial support, it's sufficient to map it to sk_filter_ops.

net/core/sysctl_net_core.c
net/ipv4/inet_diag.c
The be_main.c conflict resolution was really tricky. The conflict
hunks generated by GIT were very unhelpful, to say the least. It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().
So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged. And this worked beautifully.
The inet_diag.c and sysctl_net_core.c conflicts were simple
overlapping changes, and were easily to resolve.

Currently there are only two "tools" that can be specified by a multi-touch
driver: MT_TOOL_FINGER and MT_TOOL_PEN. In working with Elan (The touch
vendor) and discussing their next-gen devices it seems that it will be
useful to have more tools so that their devices can give the upper layers
of the stack hints as to what is touching the sensor.
In particular they have new experimental firmware that can better
differentiate between palms vs fingertips and would like to plumb a patch
so that we can use their hints in higher-level gesture soft- ware. The
firmware on the device can reasonably do a better job of palm detection
because it has access to all of the raw sensor readings as opposed to just
the width/pressure/etc that are exposed by the driver. As such, the
firmware can characterize what a palm looks like in much finer-grained
detail and this change would allow such a device to share its findings with
the kernel.

Setup new I915_GETPARAM ioctl entries for subslice total and
EU total. Userspace drivers need these values when constructing
GPGPU commands. This kernel query method is intended to replace
the PCI ID-based tables that userspace drivers currently maintain.
The kernel driver can employ fuse register reads as needed to
ensure the most accurate determination of GT config attributes.
This first became important with Cherryview in which the config
could differ between devices with the same PCI ID.
The kernel detection of these values is device-specific and not
included in this patch. Because zero is not a valid value for any of
these parameters, a value of zero is interpreted as unknown for the
device. Userspace drivers should continue to maintain ID-based tables
for older devices not supported by the new query method.

however, is only available in user space. An example of this is the
guest name: The kernel always sets "KVMGuest", but user space knows the
actual guest name.
This patch introduces a new exit, KVM_EXIT_S390_STSI, guarded by a

insert such data. User space will be provided with the target buffer

parallel values and userspace uses these parallel values for ioctls;
thus the userspace values are definitive.

Define and allocate space for both the host and guest views of
the vector registers for a given vcpu. The 32 vector registers
occupy 128 bits each (512 bytes total), but architecturally are
paired with 512 additional bytes of reserved space for future
expansion.
The kvm_sync_regs structs containing the registers are union'ed
with 1024 bytes of padding in the common kvm_run struct. The
addition of 1024 bytes of new register information clearly exceeds
the existing union, so an expansion of that padding is required.
When changing environments, we need to appropriately save and
restore the vector registers viewed by both the host and guest,
into and out of the sync_regs space.
The floating point registers overlay the upper half of vector
registers 0-15, so there's a bit of data duplication here that
needs to be carefully avoided.

Previously, the indoor setting configuration assumed that as
long as a station interface is connected, the indoor environment
setting does not change. However, this assumption is problematic
as:
- It is possible that a station interface is connected to a mobile
AP, e.g., softAP or a P2P GO, where it is possible that both the
station and the mobile AP move out of the indoor environment making
the indoor setting invalid. In such a case, user space has no way to
invalidate the setting.
- A station interface disconnection does not necessarily imply that
the device is no longer operating in an indoor environment, e.g.,
it is possible that the station interface is roaming but is still
stays indoor.
To handle the above, extend the indoor configuration API to allow
user space to indicate a change of indoor settings, and allow it to
indicate weather it controls the indoor setting, such that:
1. If the user space process explicitly indicates that it is going
to control the indoor setting, do not clear the indoor setting
internally, unless the socket is released. The user space process
should use the NL80211_ATTR_SOCKET_OWNER attribute in the command
to state that it is going to control the indoor setting.
2. Reset the indoor setting when restoring the regulatory settings in
case it is not owned by a user space process.
Based on the above, a user space tool that continuously monitors the
indoor settings, i.e., tracking power setting, location etc., can
indicate environment changes to the regulatory core.
It should be noted that currently user space is the only provided mechanism
used to hint to the regulatory core over the indoor/outdoor environment --
while the country IEs do have an environment setting this has been completely
ignored by the regulatory core by design for a while now since country IEs
typically can contain bogus data.

This extends the design in commit 958501163d ("bridge: Add support for
IEEE 802.11 Proxy ARP") with optional set of rules that are needed to
meet the IEEE 802.11 and Hotspot 2.0 requirements for ProxyARP. The
previously added BR_PROXYARP behavior is left as-is and a new
BR_PROXYARP_WIFI alternative is added so that this behavior can be
configured from user space when required.
In addition, this enables proxyarp functionality for unicast ARP
requests for both BR_PROXYARP and BR_PROXYARP_WIFI since it is possible
to use unicast as well as broadcast for these frames.
The key differences in functionality:
BR_PROXYARP:
- uses the flag on the bridge port on which the request frame was
received to determine whether to reply
- block bridge port flooding completely on ports that enable proxy ARP
BR_PROXYARP_WIFI:
- uses the flag on the bridge port to which the target device of the
request belongs
- block bridge port flooding selectively based on whether the proxyarp
functionality replied

If the device supports waking up on 'any' signal - i.e. it continues
operating as usual and wakes up the host on pretty much anything that
happens, then it makes no sense to also configure the more restricted
WoWLAN mode where the device operates more autonomously but also in a
more restricted fashion.
Currently only cw2100 supports both 'any' and other triggers, but it
seems to be broken as it doesn't configure anything to the device, so
we can't currently get into a situation where both even can correctly
be configured. This is about to change (Intel devices are going to
support both and have different behaviour depending on configuration)
so make sure the conflicting modes cannot be configured.
(It seems that cw2100 advertises 'any' and 'disconnect' as a means of
saying that's what it will always do, but that isn't really the way
this API was meant to be used nor does it actually mean anything as
'any' always implies 'disconnect' already, and the driver doesn't
change device configuration in any way depending on the settings.)

This change adds two new netlink routing attributes:
RTA_VIA and RTA_NEWDST.
RTA_VIA specifies the specifies the next machine to send a packet to
like RTA_GATEWAY. RTA_VIA differs from RTA_GATEWAY in that it
includes the address family of the address of the next machine to send
a packet to. Currently the MPLS code supports addresses in AF_INET,
AF_INET6 and AF_PACKET. For AF_INET and AF_INET6 the destination mac
address is acquired from the neighbour table. For AF_PACKET the
destination mac_address is specified in the netlink configuration.
I think raw destination mac address support with the family AF_PACKET
will prove useful. There is MPLS-TP which is defined to operate
on machines that do not support internet packets of any flavor. Further
seem to be corner cases where it can be useful. At this point
I don't care much either way.
RTA_NEWDST specifies the destination address to forward the packet
with. MPLS typically changes it's destination address at every hop.
For a swap operation RTA_NEWDST is specified with a length of one label.
For a push operation RTA_NEWDST is specified with two or more labels.
For a pop operation RTA_NEWDST is not specified or equivalently an emtpy
RTAN_NEWDST is specified.
Those new netlink attributes are used to implement handling of rt-netlink
RTM_NEWROUTE, RTM_DELROUTE, and RTM_GETROUTE messages, to maintain the
MPLS label table.
rtm_to_route_config parses a netlink RTM_NEWROUTE or RTM_DELROUTE message,
verify no unhandled attributes or unhandled values are present and sets
up the data structures for mpls_route_add and mpls_route_del.
I did my best to match up with the existing conventions with the caveats
that MPLS addresses are all destination-specific-addresses, and so
don't properly have a scope.

This work extends the "classic" BPF programmable tc classifier by
extending its scope also to native eBPF code!
This allows for user space to implement own custom, 'safe' C like
classifiers (or whatever other frontend language LLVM et al may
provide in future), that can then be compiled with the LLVM eBPF
backend to an eBPF elf file. The result of this can be loaded into
the kernel via iproute2's tc. In the kernel, they can be JITed on
major archs and thus run in native performance.
Simple, minimal toy example to demonstrate the workflow:
#include <linux/ip.h>
#include <linux/if_ether.h>
#include <linux/bpf.h>
#include "tc_bpf_api.h"
__section("classify")
int cls_main(struct sk_buff *skb)
{
return (0x800 << 16) | load_byte(skb, ETH_HLEN + __builtin_offsetof(struct iphdr, tos));
}
char __license[] __section("license") = "GPL";
The classifier can then be compiled into eBPF opcodes and loaded
via tc, for example:
clang -O2 -emit-llvm -c cls.c -o - | llc -march=bpf -filetype=obj -o cls.o
tc filter add dev em1 parent 1: bpf cls.o [...]
As it has been demonstrated, the scope can even reach up to a fully
fledged flow dissector (similarly as in samples/bpf/sockex2_kern.c).
For tc, maps are allowed to be used, but from kernel context only,
in other words, eBPF code can keep state across filter invocations.
In future, we perhaps may reattach from a different application to
those maps e.g., to read out collected statistics/state.
Similarly as in socket filters, we may extend functionality for eBPF
classifiers over time depending on the use cases. For that purpose,
cls_bpf programs are using BPF_PROG_TYPE_SCHED_CLS program type, so
we can allow additional functions/accessors (e.g. an ABI compatible
offset translation to skb fields/metadata). For an initial cls_bpf
support, we allow the same set of helper functions as eBPF socket
filters, but we could diverge at some point in time w/o problem.
I was wondering whether cls_bpf and act_bpf could share C programs,
I can imagine that at some point, we introduce i) further common
handlers for both (or even beyond their scope), and/or if truly needed
ii) some restricted function space for each of them. Both can be
abstracted easily through struct bpf_verifier_ops in future.
The context of cls_bpf versus act_bpf is slightly different though:
a cls_bpf program will return a specific classid whereas act_bpf a
drop/non-drop return code, latter may also in future mangle skbs.
That said, we can surely have a "classify" and "action" section in
a single object file, or considered mentioned constraint add a
possibility of a shared section.
The workflow for getting native eBPF running from tc [1] is as
follows: for f_bpf, I've added a slightly modified ELF parser code
from Alexei's kernel sample, which reads out the LLVM compiled
object, sets up maps (and dynamically fixes up map fds) if any, and
loads the eBPF instructions all centrally through the bpf syscall.
The resulting fd from the loaded program itself is being passed down
to cls_bpf, which looks up struct bpf_prog from the fd store, and
holds reference, so that it stays available also after tc program
lifetime. On tc filter destruction, it will then drop its reference.
Moreover, I've also added the optional possibility to annotate an
eBPF filter with a name (e.g. path to object file, or something
else if preferred) so that when tc dumps currently installed filters,
some more context can be given to an admin for a given instance (as
opposed to just the file descriptor number).
Last but not least, bpf_prog_get() and bpf_prog_put() needed to be
exported, so that eBPF can be used from cls_bpf built as a module.
Thanks to 60a3b2253c ("net: bpf: make eBPF interpreter images
read-only") I think this is of no concern since anything wanting to
alter eBPF opcode after verification stage would crash the kernel.

As discussed recently and at netconf/netdev01, we want to prevent making
bpf_verifier_ops registration available for modules, but have them at a
controlled place inside the kernel instead.
The reason for this is, that out-of-tree modules can go crazy and define
and register any verfifier ops they want, doing all sorts of crap, even
bypassing available GPLed eBPF helper functions. We don't want to offer
such a shiny playground, of course, but keep strict control to ourselves
inside the core kernel.
This also encourages us to design eBPF user helpers carefully and
generically, so they can be shared among various subsystems using eBPF.
For the eBPF traffic classifier (cls_bpf), it's a good start to share
the same helper facilities as we currently do in eBPF for socket filters.
That way, we have BPF_PROG_TYPE_SCHED_CLS look like it's own type, thus
one day if there's a good reason to diverge the set of helper functions
from the set available to socket filters, we keep ABI compatibility.
In future, we could place all bpf_prog_type_list at a central place,
perhaps.

We need to export BPF_PSEUDO_MAP_FD to user space, as it's used in the
ELF BPF loader where instructions are being loaded that need map fixups.
An initial stage loads all maps into the kernel, and later on replaces
related instructions in the eBPF blob with BPF_PSEUDO_MAP_FD as source
register and the actual fd as immediate value.
The kernel verifier recognizes this keyword and replaces the map fd with
a real pointer internally.

Both wpa_supplicant and mac80211 have and inactivity timer. By default
wpa_supplicant will be timed out in 5 minutes and mac80211's it is 30
minutes. If wpa_supplicant uses a longer timer than mac80211, it will
get unexpected disconnection by mac80211.
Using 0xffffffff instead as the configured value could solve this w/o
changing the code, but due to integer overflow in the expression used
this doesn't work. The expression is:
(current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250)
On 32bit system, the right side would overflow and be a very small
value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large,
causing unexpectedly early disconnections.
Instead allow disabling the inactivity timer to avoid this situation,
by passing the (previously invalid and useless) value 0.

Joining multicast group on ethernet level via "ip maddr" command would

Linux vxlan interfaces created via "ip link add vxlan" have the group option

By extending ip address command with option "autojoin" we can get similar
functionality for openvswitch vxlan interfaces as well as other tunneling
mechanisms that need to receive multicast traffic. The kernel code is
structured similar to how the vxlan driver does a group join / leave.
example:
ip address add 224.1.1.10/24 dev eth5 autojoin
ip address del 224.1.1.10/24 dev eth5

The alsa struct in struct media_entity_desc is now marked as deprecated.
However, the alsa struct should remain as it is since it cannot be replaced
by a simple major/minor device node description. The alsa struct was designed
to be used as an alsa card description so V4L2 drivers could use this to expose
the alsa card that they create to carry the captured audio. Such a card is not
just a PCM device, but also needs to contain the alsa subdevice information,
and it may map to multiple devices, e.g. a PCM and a mixer device, such as the
au0828 usb stick creates.
This is exactly as intended and this cannot and should not be replaced by a
simple major/minor.
However, whether this information is in the right form for an ALSA device such
that it can handle udev renaming rules as well is another matter. So mark this
alsa struct as TODO and document the problems involved.
Updated the documentation as well to reflect this and to add the 'major'
and 'minor' field documentation.
Updated the documentation to clearly state that struct dev is to be used for
(sub-)devices that create a single device node. Other devices need their own
structure here.

Audio timestamps can be extracted from sample counters, wall clocks,
PHC clocks (Ethernet AVB), on-demand synchronized snapshots. This
patch provides the ability to report timestamping capabilities, select
timestamp types and retrieve timestamp accuracy, if supported.
Details can be found in Documentations/sound/alsa/timestamping.txt
This functionality is introduced by reclaiming the reserved_aligned
field introduced by commit9c7066aef4a5eb8e4063de28f06c508bf6f2963a
in snd_pcm_status to provide userspace with selection/query capabilities.
Additional driver_tstamp and audio_tstamp_accuracy fields are also added.
snd_pcm_mmap_status remains a read-only structure with only
the audio timestamp value accessible from user space. The selection
of audio timestamp type is done through snd_pcm_status only
This commit does not impact ABI and does not impact the default
behavior. By default audio timestamp is aligned with hw_pointer and
reports the DMA position. Backwards compatibility is handled by using
the HDAudio wall clock for playback and the hw_ptr for all other
cases.
For timestamp selection a new STATUS_EXT ioctl is introduced with
read/write parameters. Alsa-lib will be modified to make use of
STATUS_EXT.

The original translation created collisions on Inquiry VPD 83 for many
existing devices. Newer specifications provide other ways to translate
based on the device's version can be used to create unique identifiers.
Version 1.1 provides an EUI64 field that uniquely identifies each
namespace, and 1.2 added the longer NGUID field for the same reason.
Both follow the IEEE EUI format and readily translate to the SCSI device
identification EUI designator type 2h. For devices implementing either,
the translation will use this type, defaulting to the EUI64 8-byte type if
implemented then NGUID's 16 byte version if not. If neither are provided,
the 1.0 translation is used, and is updated to use the SCSI String format
to guarantee a unique identifier.
Knowing when to use the new fields depends on the nvme controller's
revision. The NVME_VS macro was not decoding this correctly, so that is
fixed in this patch and moved to a more appropriate place.
Since the Identify Namespace structure required an update for the NGUID
field, this patch adds the remaining new 1.2 fields to the structure.

Adds support for NVMe metadata formats and exposes block devices for
all namespaces regardless of their format. Namespace formats that are
unusable will have disk capacity set to 0, but a handle to the block
device is created to simplify device management. A namespace is not
usable when the format requires host interleave block and metadata in
single buffer, has no provisioned storage, or has better data but failed
to register with blk integrity.
The namespace has to be scanned in two phases to support separate
metadata formats. The first establishes the sector size and capacity
prior to invoking add_disk. If metadata is required, the capacity will
be temporarilly set to 0 until it can be revalidated and registered with
the integrity extenstions after add_disk completes.
The driver relies on the integrity extensions to provide the metadata
buffer. NVMe requires this be a single physically contiguous region,
so only one integrity segment is allowed per command. If the metadata
is used for T10 PI, the driver provides mappings to save and restore
the reftag physical block translation. The driver provides no-op
functions for generate and verify if metadata is not used for protection
information. This way the setup is always provided by the block layer.
If a request does not supply a required metadata buffer, the command
is failed with bad address. This could only happen if a user manually
disables verify/generate on such a disk. The only exception to where
this is okay is if the controller is capable of stripping/generating
the metadata, which is possible on some types of formats.
The metadata scatter gather list now occupies the spot in the nvme_iod
that used to be used to link retryable IOD's, but we don't do that
anymore, so the field was unused.

Add extensible query device capabilities verb to allow adding new features.
ib_uverbs_ex_query_device is added and copy_query_dev_fields is used to copy
capability fields to be used by both ib_uverbs_query_device and
ib_uverbs_ex_query_device.
Following the discussion about this patch [1], the code now validates
the command's comp_mask is zero, returning -EINVAL for unknown values,
in order to allow extending the verb in the future.
The verb also checks the user-space provided response buffer size and
only fills in capabilities that will fit in the buffer. In attempt to
follow the spirit of presentation [2] by Tzahi Oved that was presented
during OpenFabrics Alliance International Developer Workshop 2013, the
comp_mask bits will only describe which fields are valid. Furthermore,
fields that can simply be cleared when they are not supported, do not
require a comp_mask bit at all. The verb returns a response_length
field containing the actual number of bytes written by the kernel, so
that a newer version running on an older kernel can tell which fields
were actually returned.

After UAPI header file split [1] all user-kernel interfaces were
placed under include/uapi/.
This patch moves IIO user specific API from:
* include/linux/iio/events.h => include/uapi/linux/iio/events.h
* include/linux/types.h => include/uapi/linux/types.h
Now there is no need for nasty tricks to compile userspace programs
(e.g iio_event_monitor). Just installing the kernel headers with
make headers_install command does the job.

Most of the DVB subdevs have already their own devnode.
Add support for them at the media controller API.
Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
The previous provision for DVB media controller support were to
define an ID (likely meaning the adapter number) for the DVB
devnodes.
This is just plain wrong. Just like V4L, DVB devices (and any other
device node)) are uniquely identified via a (major, minor) tuple.
This is enough to uniquely identify a devnode, no matter what
API it implements.
So, before we go too far, let's mark the old v4l, fb, dvb and alsa
"devnode" info as deprecated, and just call it as "dev".
We can latter add fields specific to each API if needed.
As we don't want to break compilation on already existing apps,
let's just keep the old definitions as-is, adding a note that
those are deprecated at media-entity.h.

In DRM/KMS we are lacking a good way to deal with tiled/compressed
formats. Especially in the case of dmabuf/prime buffer sharing, where
we cannot always rely on under-the-hood flags passed to driver specific
gem-create ioctl to pass around these extra flags.
The proposal is to add a per-plane format modifier. This allows to, if
necessary, use different tiling patters for sub-sampled planes, etc.
The format modifiers are added at the end of the ioctl struct, so for
legacy userspace it will be zero padded.
v1: original
v1.5: increase modifier to 64b
v2: Incorporate review comments from the big thread, plus a few more.
- Add a getcap so that userspace doesn't have to jump through hoops.
- Allow modifiers only when a flag is set. That way drivers know when
they're dealing with old userspace and need to fish out e.g. tiling
from other information.
- After rolling out checks for ->modifier to all drivers I've decided
that this is way too fragile and needs an explicit opt-in flag. So
do that instead.
- Add a define (just for documentation really) for the "NONE"
modifier. Imo we don't need to add mask #defines since drivers
really should only do exact matches against values defined with
fourcc_mod_code.
- Drop the Samsung tiling modifier on Rob's request since he's not yet
sure whether that one is accurate.
v3:
- Also add a new ->modifier[] array to struct drm_framebuffer and fill
it in drm_helper_mode_fill_fb_struct. Requested by Tvrkto Uruslin.
- Remove TODO in comment and add code comment that modifiers should be
properly documented, requested by Rob.

Merge tag 'dm-3.20-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper changes from Mike Snitzer:
- The most significant change this cycle is request-based DM now
supports stacking ontop of blk-mq devices. This blk-mq support
changes the model request-based DM uses for cloning a request to
relying on calling blk_get_request() directly from the underlying
blk-mq device.
An early consumer of this code is Intel's emerging NVMe hardware;
thanks to Keith Busch for working on, and pushing for, these changes.
- A few other small fixes and cleanups across other DM targets.
* tag 'dm-3.20-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
dm: inherit QUEUE_FLAG_SG_GAPS flags from underlying queues

dm: submit stacked requests in irq enabled context
dm: split request structure out from dm_rq_target_io structure
dm: remove exports for request-based interfaces without external callers
Pull nfsd updates from Bruce Fields:
"The main change is the pNFS block server support from Christoph, which
allows an NFS client connected to shared disk to do block IO to the
shared disk in place of NFS reads and writes. This also requires xfs
patches, which should arrive soon through the xfs tree, barring
unexpected problems. Support for other filesystems is also possible
if there's interest.
Thanks also to Chuck Lever for continuing work to get NFS/RDMA into
shape"

Userland code may be built using an ABI which permits linking to objects
that have more restrictive floating point requirements. For example,
userland code may be built to target the O32 FPXX ABI. Such code may be
linked with other FPXX code, or code built for either one of the more
restrictive FP32 or FP64. When linking with more restrictive code, the
overall requirement of the process becomes that of the more restrictive
code. The kernel has no way to know in advance which mode the process
will need to be executed in, and indeed it may need to change during
execution. The dynamic loader is the only code which will know the
overall required mode, and so it needs to have a means to instruct the
kernel to switch the FP mode of the process.
This patch introduces 2 new options to the prctl syscall which provide
such a capability. The FP mode of the process is represented as a
simple bitmask combining a number of mode bits mirroring those present
in the hardware. Userland can either retrieve the current FP mode of
the process:
mode = prctl(PR_GET_FP_MODE);
or modify the current FP mode of the process:
err = prctl(PR_SET_FP_MODE, new_mode);
