commit 68822bdf76f1 ("net: generalize skb freeing
deferral to per-cpu lists") added another per-cpu
cache of skbs. It was expected to be small,
and an IPI was forced whenever the list reached 128
skbs.
We might need to be able to control more precisely
queue capacity and added latency.
An IPI is generated whenever queue reaches half capacity.
Default value of the new limit is 64.

Document the Ethernet AVB IP found on RZ/V2M SoC.
It includes the Ethernet controller (E-MAC) and Dedicated Direct memory
access controller (DMAC) for transferring transmitted Ethernet frames
to and received Ethernet frames from respective storage areas in the
RAM at high speed.
The AVB-DMAC is compliant with IEEE 802.1BA, IEEE 802.1AS timing and
synchronization protocol, IEEE 802.1Qav real-time transfer, and the
IEEE 802.1Qat stream reservation protocol.
R-Car has a pair of combined interrupt lines:
ch22 = Line0_DiA | Line1_A | Line2_A
ch23 = Line0_DiB | Line1_B | Line2_B
Line0 for descriptor interrupts (which we call dia and dib).
Line1 for error related interrupts (which we call err_a and err_b).
Line2 for management and gPTP related interrupts (mgmt_a and mgmt_b).
RZ/V2M hardware has separate interrupt lines for each of these.
It has 3 clocks; the main AXI clock, the AMBA CHI (Coherent Hub
Interface) clock and a gPTP reference clock.

The last traces of the IDE driver went away in commit b7fb14d3ac63
("ide: remove the legacy ide driver") but it left behind some traces
of old documentation.
As luck would have it Randy and I would submit similar changes within
a week of each other to address this. As Randy's commit is in the doc
tree already - this delta is just the stuff my removal contained that
was not in Randy's IDE doc removal.

These were only implemented by the IDE CD driver, which has since

Pull driver core fixes from Greg KH:
"Here is one fix, and three documentation updates for 5.18-rc7.
The fix is for the firmware loader which resolves a long-reported
problem where the credentials of the firmware loader could be set to a
userspace process without enough permissions to actually load the
firmware image. Many Android vendors have been reporting this for
quite some time.
The documentation updates are for the embargoed-hardware-issues.rst
file to add a new entry, change an existing one, and sort the list to
make changes easier in the future.
All of these have been in linux-next for a while with no reported
issues"

We run a lot of automated tests when building our software and run into
OOM scenarios when the tests run unbounded. v1 memcg exports
memcg->watermark as "memory.max_usage_in_bytes" in sysfs. We use this
metric to heuristically limit the number of tests that can run in parallel
based on per test historical data.
This metric is currently not exported for v2 memcg and there is no other
easy way of getting this information. getrusage() syscall returns
"ru_maxrss" which can be used as an approximation but that's the max RSS
of a single child process across all children instead of the aggregated
max for all child processes. The only work around is to periodically poll
"memory.current" but that's not practical for short-lived one-off cgroups.
Hence, expose memcg->watermark as "memory.peak" for v2 memcg.

We must add hugetlb_free_vmemmap=on (or "off") to the boot cmdline and
reboot the server to enable or disable the feature of optimizing vmemmap
pages associated with HugeTLB pages. However, rebooting usually takes a
long time. So add a sysctl to enable or disable the feature at runtime
without rebooting. Why we need this? There are 3 use cases.
1) The feature of minimizing overhead of struct page associated with
each HugeTLB is disabled by default without passing
"hugetlb_free_vmemmap=on" to the boot cmdline. When we (ByteDance)
deliver the servers to the users who want to enable this feature, they
have to configure the grub (change boot cmdline) and reboot the
servers, whereas rebooting usually takes a long time (we have thousands
of servers). It's a very bad experience for the users. So we need a
approach to enable this feature after rebooting. This is a use case in
our practical environment.
2) Some use cases are that HugeTLB pages are allocated 'on the fly'
instead of being pulled from the HugeTLB pool, those workloads would be
affected with this feature enabled. Those workloads could be
identified by the characteristics of they never explicitly allocating
huge pages with 'nr_hugepages' but only set 'nr_overcommit_hugepages'
and then let the pages be allocated from the buddy allocator at fault
time. We can confirm it is a real use case from the commit
099730d67417. For those workloads, the page fault time could be ~2x
slower than before. We suspect those users want to disable this
feature if the system has enabled this before and they don't think the
memory savings benefit is enough to make up for the performance drop.
3) If the workload which wants vmemmap pages to be optimized and the
workload which wants to set 'nr_overcommit_hugepages' and does not want
the extera overhead at fault time when the overcommitted pages be
allocated from the buddy allocator are deployed in the same server.
The user could enable this feature and set 'nr_hugepages' and
'nr_overcommit_hugepages', then disable the feature. In this case, the
overcommited HugeTLB pages will not encounter the extra overhead at
fault time.

Extend and rework the "Temporary Virtual Mappings" section of the
highmem.rst documentation.
Despite the local kmaps were introduced by Thomas Gleixner in October
2020, documentation was still missing information about them. These
additions rely largely on Gleixner's patches, Jonathan Corbet's LWN
articles, comments by Ira Weiny and Matthew Wilcox, and in-code comments
from ./include/linux/highmem.h.
1) Add a paragraph to document kmap_local_page().
2) Reorder the list of functions by decreasing order of preference
of use.
3) Rework part of the kmap() entry in list.

The use of kmap_atomic() is new code is being deprecated in favor of
kmap_local_page(). For this reason the "Using kmap_atomic" section in
highmem.rst is obsolete and unnecessary, but it can still help developers
if it were moved to kdocs in highmem.h.
Therefore, move the relevant parts of this section from highmem.rst and
merge them with the kdocs in highmem.h.

This adds the new nf_conntrack_events=2 mode and makes it the
default.
This leverages the earlier flag in struct net to allow to avoid
the event extension as long as no event listener is active in
the namespace.
This avoids, for most cases, allocation of ct->ext area.
A followup patch will take further advantage of this by avoiding
calls down into the event framework if the extension isn't present.

- Fix UAF in SMMUv3 shared virtual addressing code
- Force identity-mapped domains for users of ye olde SMMU legacy binding
- Minor cleanups

These two fields need documentation as they have dual meaning. It is also
confusing since pic_num is a derived value from frame_num, so this should
help application developers. If we ever need to make a V2 of this API, I
would suggest to remove pic_num entirely.

The x86 Chromebooks have the ChromeOS ACPI device. This driver attaches
to the ChromeOS ACPI device and exports the values reported by ACPI in a
sysfs directory. This data isn't present in ACPI tables when read
through ACPI tools, hence a driver is needed to do it. The driver gets
data from firmware using the ACPI component of the kernel. The ACPI values
are presented in string form (numbers as decimal values) or binary
blobs, and can be accessed as the contents of the appropriate read only
files in the standard ACPI device's sysfs directory tree. This data is
consumed by the ChromeOS user space.

Add documentation for In-Field Scan (IFS). This documentation
describes the basics of IFS, the loading IFS image, chunk
authentication, running scan and how to check result via sysfs.
The CORE_CAPABILITIES MSR enumerates whether IFS is supported.
The full github location for distributing the IFS images is
still being decided. So just a placeholder included for now
in the documentation.
Future CPUs will support more than one type of test. Plan for
that now by using a "_0" suffix on the ABI directory names.
Additional test types will use "_1", etc.
