Currently these functions are implemented in the scsi layer, but their
actual place should be the block layer since T10-PI is a general data
integrity feature that is used in the nvme protocol as well. Also, use
the tuple size from the integrity profile since it may vary between
integrity types.

We need to check in blkcg_bio_issue_check if the bio is flagged as
QUEUE_ENTERED, because if it is then we've already accounted for the
size of the IO in the cgroup stats. We can still however account for
the extra IO since it'll be another request.

Currently when min_power policy is selected, the partial low power state
is not entered and link will try aggressively enter to only slumber state.
Add a new policy which still enable DEVSLP but also try to enter partial
low power state. This policy is presented as "min_power_with_partial".
For information the difference between partial and slumber
Partial – PHY logic is powered up, and in a reduced power state. The link
PM exit latency to active state maximum is 10 ns.
Slumber – PHY logic is powered up, and in a reduced power state. The link
PM exit latency to active state maximum is 10 ms.
Devslp – PHY logic is powered down. The link PM exit latency from this
state to active state maximum is 20 ms, unless otherwise specified by
DETO.

The trigger flag in vmidi object can be referred in different contexts
concurrently, hence it's better to be put with READ_ONCE() and
WRITE_ONCE() macros to assure the accesses.

The virmidi sequencer stuff tries to translate the rawmidi bytes to
sequencer events and deliver the packets at trigger callback. The
amount of the whole process of these translations and deliveries
depends on the incoming rawmidi bytes, and we have no limit for that;
this was the cause of a CPU soft lockup that had been reported and
fixed recently.
Although we've fixed the soft lockup by putting the temporary unlock
and cond_resched(), it's rather a quick band aid. In this patch,
meanwhile, the event parsing and delivery process is offloaded to a
dedicated work, and the trigger callback just kicks it off. It has
three merits, at least:
- The processing is always done in a sleepable context, which can
assure the event delivery with non-atomic flag without hackish
is_atomic() usage.
- Other relevant codes can be simplified, reducing the lines
- It makes me happier

Add drm_puts() for a much faster path to print constant strings

A great portion of the code is taken from xt_TPROXY.c
There are some changes compared to the iptables implementation:
- tproxy statement is not terminal here
- Either address or port has to be specified, but at least one of them
is necessary. If one of them is not specified, the evaluation will be
performed with the original attribute of the packet (ie. target port
is not specified => the packet's dport will be used).
To make this work in inet tables, the tproxy structure has a family
member (typically called priv->family) which is not necessarily equal to
ctx->family.
priv->family can have three values legally:
- NFPROTO_IPV4 if the table family is ip OR if table family is inet,
but an ipv4 address is specified as a target address. The rule only
evaluates ipv4 packets in this case.
- NFPROTO_IPV6 if the table family is ip6 OR if table family is inet,
but an ipv6 address is specified as a target address. The rule only
evaluates ipv6 packets in this case.
- NFPROTO_UNSPEC if the table family is inet AND if only the port is
specified. The rule will evaluate both ipv4 and ipv6 packets.

This basically sets the random address for the adv instance
Random address can be set only if the instance is created which
is done in Set ext adv param.
Random address and rpa expire timer and flags have been added
to adv instance which will be used when the respective
instance is scheduled.
This introduces a hci_get_random_address() which returns the
own address type and random address (rpa or nrpa) based
on the instance flags and hdev flags. New function is required
since own address type should be known before setting adv params
but address can be set only after setting params.

based on the controller support. Currently there is no
design change. ie only one adv set will be enabled at a time.
This also adds tx_power in instance and store whatever returns

usb: changes for v4.19
Not a big pull request with only 37 non-merge commits, most of which
are touching dwc2 (74% of the changes).
The most important changes are dwc2's support for uframe scheduling
and its endian-agnostic readl/writel wrappers.
From dwc3 side we have a special new glue layer for Synopsys HAPS
which will help Synopsys running FPGA validation using our upstream
driver. We also have the beginnings of dual-role support for Intel
Merrifield platform.
Apart from these, just a series of non-critical changes.

- reflect 4789 UDP port default addition to software database
- check maximum number of vxlan UDP ports
- cleanup an unused member in vxlan work
Then Gal provides performance optimization by replacing the
vxlan radix tree with a hash table.
Measuring mlx5e_vxlan_lookup_port execution time:
Radix Tree Hash Table
--------------- ------------ ------------
Single Stream 161 ns 79 ns (51% improvement)
Multi Stream 259 ns 136 ns (47% improvement)
Measuring UDP stream packet rate, single fully utilized TX core:
Radix Tree: 498,300 PPS
Hash Table: 555,468 PPS (11% improvement)
Next, from Saeed, vxlan refactoring to allow sharing the vxlan table
between different mlx5 netdevice instances like PF and VF representors,
this is done by making mlx5 vxlan interface more generic and decoupling
it from PF netdevice structures and logic, then moving it into mlx5 core
as a low level interface so it can be used by VF representors, which is
illustrated in the last patch of the serious.

If an invalid MTU value is set through rtnetlink return extra error
information instead of putting message in kernel log. For other cases
where there is no visible API, keep the error report in the log.
Example:
# ip li set dev enp12s0 mtu 10000
Error: mtu greater than device maximum.
# ifconfig enp12s0 mtu 10000
SIOCSIFMTU: Invalid argument
# dmesg | tail -1
[ 2047.795467] enp12s0: mtu greater than device maximum

Commit ee2059819450 ("net/dcb: Add dscp to priority selector type")
added a define for the new DSCP selector type created by
IEEE 802.1Qcd, but missed the comment enumerating all selector types.
Update the comment.

This patch implements the feature described in rfc1812#section-5.3.5.2
and rfc2644. It allows the router to forward directed broadcast when
sysctl bc_forwarding is enabled.
Note that this feature could be done by iptables -j TEE, but it would
cause some problems:
- target TEE's gateway param has to be set with a specific address,
and it's not flexible especially when the route wants forward all
directed broadcasts.
- this duplicates the directed broadcasts so this may cause side
effects to applications.
Besides, to keep consistent with other os router like BSD, it's also
necessary to implement it in the route rx path.
Note that route cache needs to be flushed when bc_forwarding is
changed.

====================
pull-request: can-next 2018-01-16
this is a pull request for net-next/master consisting of 38 patches.
Dan Murphy's patch fixes the path to a file in the comment of the CAN
Error Message Frame Mask structure.
A patch by Colin Ian King fixes a typo in the cc770 driver.
The next patch is by me an sorts the Kconfigand Makefile entries of the
CAN-USB driver subdir alphabetically.
The patch by Jakob Unterwurzacher adds support for the UCAN USB-CAN
adapter.
YueHaibing's patch replaces a open coded skb_put()+memset() by
skb_put_zero() in the CAN-dev infrastructure.
Zhu Yi provides a patch to enable multi-queue CAN devices.
Three patches by Luc Van Oostenryck fix the return value of several
driver's xmit function, I contribute a patch for the a fourth driver.
Fabio Estevam's patch switches the flexcan driver to SPDX identifier.
Two patches by Jia-Ju Bai replace the mdelay() by a usleep_range() in
the sja1000 drivers.
The next 6 patches are by Anssi Hannula and refactor the xilinx CAN
driver and add support for the xilinx CAN FD core.
A patch by Gustavo A. R. Silva adds fallthrough annotation to the
peak_usb driver.
5 patches by Stephane Grosjean for the peak CANFD driver do some
cleanups and provide more improvements for further firmware releases.
The remaining 13 patches are by Jimmy Assarsson and the first clean up
the kvaser_usb driver, so that the later patches add support for the
Kvaser USB hydra family.

at24: updates for v4.19
New property: 'address-width' which allows to specify the number of
addressing bits. Up until now we only could choose one of the defined
models and rely on the flags specified in its corresponding chip data
structure.
