snd_usb_pipe_sanity_check() is a great function, so let's move it into
the USB core so that other parts of the kernel, including the USB core,
can call it.
Name it usb_pipe_type_check() to match the existing
usb_urb_ep_type_check() call, which now uses this function.

The request queue is currently run unconditionally in scsi_end_request() if
both target queue and host queue are ready.
Recently Long Li reported that cost of a queue run can be very heavy in
case of high queue depth. Improve this situation by only running the
request queue when this LUN is busy.

To support modifying the used_maps array, we use a mutex to protect
the use of the counter and the array. The mutex is initialized right
after the prog aux is allocated, and destroyed right before prog
aux is freed. This way we guarantee it's initialized for both cBPF
and eBPF.

When CONFIG_BLK_DEV_ZONED is disabled, allow using host-aware ZBC disks as
regular disks. In this case, ensure that command completion is correctly
executed by changing sd_zbc_complete() to return good_bytes instead of 0
and causing a hang during device probe (endless retries).
When CONFIG_BLK_DEV_ZONED is enabled and a host-aware disk is detected to
have partitions, it will be used as a regular disk. In this case, make sure
to not do anything in sd_zbc_revalidate_zones() as that triggers warnings.
Since all these different cases result in subtle settings of the disk queue
zoned model, introduce the block layer helper function
blk_queue_set_zoned() to generically implement setting up the effective
zoned model according to the disk type, the presence of partitions on the
disk and CONFIG_BLK_DEV_ZONED configuration.

Currently, the only listener of the nexthop notification chain is the
VXLAN driver. Subsequent patches will add more listeners (e.g., device
drivers such as netdevsim) that need to be able to block when processing
notifications.
Therefore, convert the notification chain to a blocking one. This is
safe as notifications are always emitted from process context.

Currently drivers have to report their pause frames statistics
via ethtool -S, and there is a wide variety of names used for
these statistics.
Add the two statistics defined in IEEE 802.3x to the standard
API. Create a new ethtool request header flag for including
statistics in the response to GET commands.
Always create the ETHTOOL_A_PAUSE_STATS nest in replies when
flag is set. Testing if driver declares the op is not a reliable
way of checking if any stats will actually be included and therefore
we don't want to give the impression that presence of
ETHTOOL_A_PAUSE_STATS indicates driver support.
Note that this patch does not include PFC counters, which may fit
better in dcbnl? But mostly I don't need them/have a setup to test
them so I haven't looked deeply into exposing them :)

Add CQE compression support for completions of packets that span
multiple strides in a Striding RQ, per the HW capability.
In our memory model, we use small strides (256B as of today) for the
non-linear SKB mode. This feature allows CQE compression to work also
for multiple strides packets. In this case decompressing the mini CQE
array will use stride index provided by HW as part of the mini CQE.
Before this feature, compression was possible only for single-strided
packets, i.e. for packets of size up to 256 bytes when in non-linear
mode, and the index was maintained by SW.
This feature is supported for ConnectX-5 and above.
Feature performance test:
This was whitebox-tested, we reduced the PCI speed from 125Gb/s to
62.5Gb/s to overload pci and manipulated mlx5 driver to drop incoming
packets before building the SKB to achieve low cpu utilization.
Outcome is low cpu utilization and bottleneck on pci only.
Test setup:
Server: Intel(R) Xeon(R) Silver 4108 CPU @ 1.80GHz server, 32 cores
NIC: ConnectX-6 DX.
Sender side generates 300 byte packets at full pci bandwidth.
Receiver side configuration:
Single channel, one cpu processing with one ring allocated. Cpu utilization
is ~20% while pci bandwidth is fully utilized.
For the generated traffic and interface MTU of 4500B (to activate the
non-linear SKB mode), packet rate improvement is about 19% from ~17.6Mpps
to ~21Mpps.
Without this feature, counters show no CQE compression blocks for
this setup, while with the feature, counters show ~20.7Mpps compressed CQEs
in ~500K compression blocks.

Using the same register-bound variable for both arguments and results
means these values share a type. That type must allow the arguments to
be assigned to it and must also be assignable to the unsigned long
fields of struct arm_smccc_res.
This restriction on types causes compiler warnings when the argument
cannot be implicitly assigned to an unsigned long, for example the
pointers that are used in the KVM hyp interface.
By separating the arguments and results into their own variables, the
type constraint is lifted allowing the arguments to avoid the need for
any type conversion.

We fail to get the BMCS's device id with low probability when loading
the ipmi driver and it causes BMC device registration failed. When this
issue occurs we got below kernel prints:
[Wed Sep 9 19:52:03 2020] ipmi_si IPI0001:00: IPMI message handler:
device id demangle failed: -22
[Wed Sep 9 19:52:03 2020] IPMI BT: using default values
[Wed Sep 9 19:52:03 2020] IPMI BT: req2rsp=5 secs retries=2
[Wed Sep 9 19:52:03 2020] ipmi_si IPI0001:00: Unable to get the
device id: -5
[Wed Sep 9 19:52:04 2020] ipmi_si IPI0001:00: Unable to register
device: error -5
When this issue happens, we want to manually unload the driver and try to
load it again, but it can't be unloaded by 'rmmod' as it is already 'in
use'.
We add a print in handle_one_recv_msg(), when this issue happens,
the msg we received is "Recv: 1c 01 d5", which means the data_len is 1,
data[0] is 0xd5 (completion code), which means "bmc cannot execute
command. Command, or request parameter(s), not supported in present
state". Debug code:
static int handle_one_recv_msg(struct ipmi_smi *intf,
struct ipmi_smi_msg *msg) {
printk("Recv: %*ph\n", msg->rsp_size, msg->rsp);
... ...
}
Then in ipmi_demangle_device_id(), it returned '-EINVAL' as 'data_len < 7'
and 'data[0] != 0'.
We created this patch to retry the get device id when this error
happens. We reproduced this issue again and the retry succeed on the
first retry, we finally got the correct msg and then all is ok:
Recv: 1c 01 00 01 81 05 84 02 af db 07 00 01 00 b9 00 10 00
So use a retry machanism in this patch to give bmc more opportunity to
correctly response kernel when we received specific completion codes.

The 8xx has 4 page sizes: 4k, 16k, 512k and 8M
4k and 16k can be selected at build time as standard page sizes,
and 512k and 8M are hugepages.
When 4k standard pages are selected, 16k pages are not available.
Allow 16k pages as hugepages when 4k pages are used.
To allow that, implement arch_make_huge_pte() which receives
the necessary arguments to allow setting the PTE in accordance
with the page size:
- 512 k pages must have _PAGE_HUGE and _PAGE_SPS. They are set
by pte_mkhuge(). arch_make_huge_pte() does nothing.
- 16 k pages must have only _PAGE_SPS. arch_make_huge_pte() clears

SOCK_QUEUE_SHRUNK is currently used by TCP as a temporary state
that remembers if some room has been made in the rtx queue
by an incoming ACK packet.
This is later used from tcp_check_space() before
considering to send EPOLLOUT.
Problem is: If we receive SACK packets, and no packet
is removed from RTX queue, we can send fresh packets, thus
moving them from write queue to rtx queue and eventually
empty the write queue.
This stall can happen if TCP_NOTSENT_LOWAT is used.
With this fix, we no longer risk stalling sends while holes
are repaired, and we can fully use socket sndbuf.
This also removes a cache line dirtying for typical RPC
workloads.

better handle incrementing page count"), and refcount is not added
every time, so change prefetchw as prefetch.
Now it mainly services page_address(), but which accesses struct page
only when WANT_PAGE_VIRTUAL or HASHED_PAGE_VIRTUAL is defined otherwise
it returns address based on offset, so we prefetch it conditionally.

Add menu control for VP9 codec levels. A total of 14 levels are
defined for Profile 0 (8bit) and Profile 2 (10bit). Each level
is a set of constrained bitstreams coded with targeted resolutions,
frame rates, and bitrates.
The definitions have been taken from webm project [1].

The patch partially reverts some of the UAPI bits of the buffer
cache management hints. Namely, the queue consistency (memory
coherency) user-space hint because, as it turned out, the kernel
implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT.
The patch reverts both kernel and user space parts: removes the
DMA consistency attr functions, rolls back changes to v4l2_requestbuffers,
v4l2_create_buffers structures and corresponding UAPI functions
(plus compat32 layer) and cleans up the documentation.

Now that devprop_gpiochip_set_names() is only used in a single place
inside drivers/gpio/gpiolib.c, there's no need anymore for it to be
exported or to even live in its own source file. Pull this function into
the core source file for gpiolib.

devprop_gpiochip_set_names() is overly complicated with taking the
fwnode argument (which requires using dev_fwnode() & of_fwnode_handle()
in ACPI and OF GPIO code respectively). Let's just switch to using the
generic device properties.
This allows us to pull the code setting line names directly into
gpiochip_add_data_with_key() instead of handling it separately for
ACPI and OF.

Instead of doing the following:
count = device_property_read_string_array(dev, propname, NULL, 0);
Let's provide inline helpers with hardcoded arguments for counting
strings in property arrays.

VRAM helpers support ref counting for pin and vmap operations, no need
to avoid these operations by employing the internal kmap interface. Just
use drm_gem_vram_vmap() and let it handle the details.
Also unexport the kmap interfaces from VRAM helpers. Vboxvideo was the
last user of these internal functions.
