We can hook this up to the block layer, to help throttle buffered
writes.
wbt registers a few trace points that can be used to track what is
happening in the system:
wbt_lat: 259:0: latency 2446318
wbt_stat: 259:0: rmean=2446318, rmin=2446318, rmax=2446318, rsamples=1,
wmean=518866, wmin=15522, wmax=5330353, wsamples=57
wbt_step: 259:0: step down: step=1, window=72727272, background=8, normal=16, max=32
This shows a sync issue event (wbt_lat) that exceeded it's time. wbt_stat
dumps the current read/write stats for that window, and wbt_step shows a
step down event where we now scale back writes. Each trace includes the
device, 259:0 in this case.

For legacy block, we simply track them in the request queue. For
blk-mq, we track them on a per-sw queue basis, which we can then
sum up through the hardware queues and finally to a per device
state.
The stats are tracked in, roughly, 0.1s interval windows.
Add sysfs files to display the stats.
The feature is off by default, to avoid any extra overhead. In-kernel
users of it can turn it on by setting QUEUE_FLAG_STATS in the queue
flags. We currently don't turn it on if someone just reads any of
the stats files, that is something we could add as well.

This adds a shared per-request structure for all NVMe I/O. This structure
is embedded as the first member in all NVMe transport drivers request
private data and allows to implement common functionality between the
drivers.
The first use is to replace the current abuse of the SCSI command
passthrough fields in struct request for the NVMe command passthrough,
but it will grow a field more fields to allow implementing things
like common abort handlers in the future.
The passthrough commands are handled by having a pointer to the SQE
(struct nvme_command) in struct nvme_request, and the union of the
possible result fields, which had to be turned from an anonymous
into a named union for that purpose. This avoids having to pass
a reference to a full CQE around and thus makes checking the result
a lot more lightweight.

With CONFIG_OF enabled on x86, we get the following error on boot:
"
Failed to find cpu0 device node
Unable to detect cache hierarchy from DT for CPU 0
"
and the cacheinfo fails to get populated in the corresponding sysfs
entries. This is because cache_setup_of_node looks for of_node for
setting up the shared cpu_map without checking that it's already
populated in the architecture specific callback.
In order to indicate that the shared cpu_map is already populated, this
patch introduces a boolean `cpu_map_populated` in struct cpu_cacheinfo
that can be used by the generic code to skip cache_shared_cpu_map_setup.
This patch also sets that boolean for x86.

This framework adds API functions for enabling/
disabling FPGA bridges under kernel control.
This allows the Linux kernel to disable FPGA bridges
during FPGA reprogramming and to enable FPGA bridges
when FPGA reprogramming is done. This framework is
be manufacturer-agnostic, allowing it to be used in
interfaces that use the FPGA Manager Framework to
reprogram FPGA's.
The functions are:
* of_fpga_bridge_get
* fpga_bridge_put
Get/put an exclusive reference to a FPGA bridge.
* fpga_bridge_enable
* fpga_bridge_disable
Enable/Disable traffic through a bridge.
* fpga_bridge_register
* fpga_bridge_unregister
Register/unregister a device-specific low level FPGA
Bridge driver.
Get an exclusive reference to a bridge and add it to a list:
* fpga_bridge_get_to_list
To enable/disable/put a set of bridges that are on a list:
* fpga_bridges_enable
* fpga_bridges_disable
* fpga_bridges_put

This patch adds a minor change in the FPGA Manager API
to hold information that is specific to an FPGA image
file. This change is expected to bring little, if any,
pain. The socfpga and zynq drivers are fixed up in
this patch.
An FPGA image file will have particulars that affect how the
image is programmed to the FPGA. One example is that
current 'flags' currently has one bit which shows whether the
FPGA image was built for full reconfiguration or partial
reconfiguration. Another example is timeout values for
enabling or disabling the bridges in the FPGA. As the
complexity of the FPGA design increases, the bridges in the
FPGA may take longer times to enable or disable.
This patch adds a new 'struct fpga_image_info', moves the
current 'u32 flags' to it. Two other image-specific u32's
are added for the bridge enable/disable timeouts. The FPGA
Manager API functions are changed, replacing the 'u32 flag'
parameter with a pointer to struct fpga_image_info.
Subsequent patches fix the existing low level FPGA manager
drivers.

This patch add of overlay notifications.
When DT overlays are being added, some drivers/subsystems
need to see device tree overlays before the changes go into
the live tree.
This is distinct from reconfig notifiers that are
post-apply or post-remove and which issue very granular
notifications without providing access to the context
of a whole overlay.
The following 4 notificatons are issued:
OF_OVERLAY_PRE_APPLY
OF_OVERLAY_POST_APPLY
OF_OVERLAY_PRE_REMOVE
OF_OVERLAY_POST_REMOVE
In the case of pre-apply notification, if the notifier
returns error, the overlay will be rejected.
This patch exports two functions for registering/unregistering
notifications:
of_overlay_notifier_register(struct notifier_block *nb)
of_overlay_notifier_unregister(struct notifier_block *nb)
The of_mutex is held during these notifications. The
notification data includes pointers to the overlay target
and the overlay:
struct of_overlay_notify_data {
struct device_node *overlay;
struct device_node *target;
};

We keep running into cases where device drivers want to know the exact
version of the a SoC they are currently running on. In the past, this has
usually been done through a vendor specific API that can be called by a
driver, or by directly accessing some kind of version register that is
not part of the device itself but that belongs to a global register area
of the chip.
Common reasons for doing this include:
- A machine is not using devicetree or similar for passing data about
on-chip devices, but just announces their presence using boot-time
platform devices, and the machine code itself does not care about the
revision.
- There is existing firmware or boot loaders with existing DT binaries
with generic compatible strings that do not identify the particular
revision of each device, but the driver knows which SoC revisions
include which part.
- A prerelease version of a chip has some quirks and we are using the same
version of the bootloader and the DT blob on both the prerelease and the
final version. An update of the DT binding seems inappropriate because
that would involve maintaining multiple copies of the dts and/or
bootloader.
This patch introduces the soc_device_match() interface that is meant to
work like of_match_node() but instead of identifying the version of a
device, it identifies the SoC itself using a vendor-agnostic interface.
Unlike of_match_node(), we do not do an exact string compare but instead
use glob_match() to allow wildcards in strings.

The internal PTP Hardware Clock (PHC) interface limits the resolution for
frequency adjustments to one part per billion. However, some hardware
devices allow finer adjustment, and making use of the increased resolution
improves synchronization measurably on such devices.
This patch adds an alternative method that allows finer frequency tuning
by passing the scaled ppm value to PHC drivers. This value comes from
user space, and it has a resolution of about 0.015 ppb. We also deprecate
the older method, anticipating its removal once existing drivers have been
converted over.

This patch adds the necessary functions to compute and check the HMAC signature
of an SR-enabled packet. Two HMAC algorithms are supported: hmac(sha1) and
hmac(sha256).
In order to avoid dynamic memory allocation for each HMAC computation,
a per-cpu ring buffer is allocated for this purpose.
A new per-interface sysctl called seg6_require_hmac is added, allowing a
user-defined policy for processing HMAC-signed SR-enabled packets.
A value of -1 means that the HMAC field will always be ignored.
A value of 0 means that if an HMAC field is present, its validity will
be enforced (the packet is dropped is the signature is incorrect).
Finally, a value of 1 means that any SR-enabled packet that does not
contain an HMAC signature or whose signature is incorrect will be dropped.

This patch creates a new type of interfaceless lightweight tunnel (SEG6),
enabling the encapsulation and injection of SRH within locally emitted
packets and forwarded packets.
>From a configuration viewpoint, a seg6 tunnel would be configured as follows:
ip -6 ro ad fc00::1/128 encap seg6 mode encap segs fc42::1,fc42::2,fc42::3 dev eth0
Any packet whose destination address is fc00::1 would thus be encapsulated
within an outer IPv6 header containing the SRH with three segments, and would
actually be routed to the first segment of the list. If `mode inline' was
specified instead of `mode encap', then the SRH would be directly inserted
after the IPv6 header without outer encapsulation.
The inline mode is only available if CONFIG_IPV6_SEG6_INLINE is enabled. This
feature was made configurable because direct header insertion may break
several mechanisms such as PMTUD or IPSec AH.

This patch adds the necessary hooks and structures to provide support
for SR-IPv6 control plane, essentially the Generic Netlink commands
that will be used for userspace control over the Segment Routing
kernel structures.
The genetlink commands provide control over two different structures:
tunnel source and HMAC data. The tunnel source is the source address
that will be used by default when encapsulating packets into an
outer IPv6 header + SRH. If the tunnel source is set to :: then an
address of the outgoing interface will be selected as the source.
The HMAC commands currently just return ENOTSUPP and will be implemented
in a future patch.

as described in
https://tools.ietf.org/html/draft-ietf-6man-segment-routing-header-02.
This patch implements the following operations:
- Intermediate segment endpoint: incrementation of active segment and rerouting.
- Egress for SR-encapsulated packets: decapsulation of outer IPv6 header + SRH
and routing of inner packet.
- Cleanup flag support for SR-inlined packets: removal of SRH if we are the
penultimate segment endpoint.
A per-interface sysctl seg6_enabled is provided, to accept/deny SR-enabled
packets. Default is deny.

Netfilter fixes for net
The following patchset contains a larger than usual batch of Netfilter
fixes for your net tree. This series contains a mixture of old bugs and
recently introduced bugs, they are:
1) Fix a crash when using nft_dynset with nft_set_rbtree, which doesn't

Zhang.
2) Fix leak when nft_expr_clone() fails, from Liping Zhang.
3) Fix a race when inserting new elements to the set hash from the
packet path, also from Liping.
4) Handle segmented TCP SIP packets properly, basically avoid that the
INVITE in the allow header create bogus expectations by performing
stricter SIP message parsing, from Ulrich Weber.
5) nft_parse_u32_check() should return signed integer for errors, from
John Linville.
6) Fix wrong allocation instead of connlabels, allocate 16 instead of
32 bytes, from Florian Westphal.
7) Fix compilation breakage when building the ip_vs_sync code with
CONFIG_OPTIMIZE_INLINING on x86, from Arnd Bergmann.
8) Destroy the new set if the transaction object cannot be allocated,
also from Liping Zhang.
9) Use device to route duplicated packets via nft_dup only when set by
the user, otherwise packets may not follow the right route, again
from Liping.
10) Fix wrong maximum genetlink attribute definition in IPVS, from
WANG Cong.
11) Ignore untracked conntrack objects from xt_connmark, from Florian
Westphal.
12) Allow to use conntrack helpers that are registered NFPROTO_UNSPEC
via CT target, otherwise we cannot use the h.245 helper, from
Florian.
13) Revisit garbage collection heuristic in the new workqueue-based
timer approach for conntrack to evict objects earlier, again from
Florian.
14) Fix crash in nf_tables when inserting an element into a verdict map,
from Liping Zhang.

We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.
To fix this, this patch changes acpi_create_platform_device

Some basic expressions are built into nf_tables.ko, such as nft_cmp,
nft_lookup, nft_range and so on. But these basic expressions' init
routine is a little ugly, too many goto errX labels, and we forget
to call nft_range_module_exit in the exit routine, although it is
harmless.
Acctually, the init and exit routines of these basic expressions
are same, i.e. do nft_register_expr in the init routine and do
nft_unregister_expr in the exit routine.
So it's better to arrange them into an array and deal with them
together.

Enum value of 'tps65217_irq_type' is not matched with DT parsed hwirq
number[*].
The MFD driver gets the IRQ data by referencing hwirq, but the value is
different. So, irq_to_tps65217_irq() returns mismatched IRQ data.
Eventually, the power button driver enables not PB but USB interrupt
when it is probed.
According to the TPS65217 register map[**], USB interrupt is the LSB.
This patch defines synchronized IRQ value.

TPS65217 supports three interrupt sources. This patch enables assigning
each IRQ number in the charger and power button node. Then corresponding
IRQ will be requested by each driver.

It only returns 0 so we can save us the testing of its retval
everywhere.

Pull sound fixes from Takashi Iwai:
"This became a largish pull-request, as we've got a bunch of pending
ASoC fixes at this time. One noticeable change is the removal of error
directive in uapi/sound/asoc.h. We found that the API has been already
used on Chromebooks, so we need to support it even now.
A slight big LOC is found in Qualcomm lpass driver, but the rest are
all small and easy fixes for ASoC drivers (sti, sun4i, Realtek codecs,
Intel, tas571x, etc) in addition to the patches to harden the ALSA
core proc file accesses"
