We already know that the HiHope RZ/G2 EX will also sit on the
HiHope RZ/G2N, even though the HiHope RZ/G2N doesn't exist just
yet.

The J721E SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration to enable lower system costs
of automotive applications such as infotainment, cluster, premium
Audio, Gateway, industrial and a range of broad market applications.
This SoC is designed around reducing the system cost by eliminating
the need of an external system MCU and is targeted towards ASIL-B/C
certification/requirements in addition to allowing complex software
and system use-cases.
Some highlights of this SoC are:
* Dual Cortex-A72s in a single cluster, three clusters of lockstep
capable dual Cortex-R5F MCUs, Deep-learning Matrix Multiply Accelerator(MMA),
C7x floating point Vector DSP, Two C66x floating point DSPs.
* 3D GPU PowerVR Rogue 8XE GE8430
* Vision Processing Accelerator (VPAC) with image signal processor and Depth
and Motion Processing Accelerator (DMPAC)
* Two Gigabit Industrial Communication Subsystems (ICSSG), each with dual
PRUs and dual RTUs
* Two CSI2.0 4L RX plus one CSI2.0 4L TX, one eDP/DP, One DSI Tx, and
up to two DPI interfaces.
* Integrated Ethernet switch supporting up to a total of 8 external ports in
addition to legacy Ethernet switch of up to 2 ports.
* System MMU (SMMU) Version 3.0 and advanced virtualisation
capabilities.
* Upto 4 PCIe-GEN3 controllers, 2 USB3.0 Dual-role device subsystems,
16 MCANs, 12 McASP, eMMC and SD, UFS, OSPI/HyperBus memory controller, QSPI,
I3C and I2C, eCAP/eQEP, eHRPWM, MLB among other peripherals.
* Two hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
management.
* Configurable L3 Cache and IO-coherent architecture with high data throughput
capable distributed DMA architecture under NAVSS
* Centralized System Controller for Security, Power, and Resource
Management (DMSC)

Pull cgroup fixes from Tejun Heo:
"This has an unusually high density of tricky fixes:
- task_get_css() could deadlock when it races against a dying cgroup.
- cgroup.procs didn't list thread group leaders with live threads.
This could mislead readers to think that a cgroup is empty when
it's not. Fixed by making PROCS iterator include dead tasks. I made
a couple mistakes making this change and this pull request contains
a couple follow-up patches.
- When cpusets run out of online cpus, it updates cpusmasks of member
tasks in bizarre ways. Joel improved the behavior significantly"

Add another example to clarify that HugePages smaller than 1MB will
be displayed using "KB", with an uppercased K (eg. 20KB), and not the
normal SI prefix kilo (small k).
Because of a misunderstanding/copy-paste error inside runc
(see https://github.com/opencontainers/runc/pull/2065), it tried
accessing the cgroup control file of a 64kB HugePage using
"hugetlb.64kB._____" instead of the correct "hugetlb.64KB._____".
Adding a new example will make it clear how sizes smaller than 1MB are
handled.

Pull arm64 fixes from Will Deacon:
"Here are some arm64 fixes for -rc5.
The only non-trivial change (in terms of the diffstat) is fixing our
SVE ptrace API for big-endian machines, but the majority of this is
actually the addition of much-needed comments and updates to the
documentation to try to avoid this mess biting us again in future.
There are still a couple of small things on the horizon, but nothing
major at this point.
Summary:
- Fix broken SVE ptrace API when running in a big-endian configuration
- Fix performance regression due to off-by-one in TLBI range checking
- Fix build regression when using Clang"

The in-memory representation of SVE and FPSIMD registers is
different: the FPSIMD V-registers are stored as single 128-bit
host-endian values, whereas SVE registers are stored in an
endianness-invariant byte order.
This means that the two representations differ when running on a
big-endian host. But we blindly copy data from one representation
to another when converting between the two, resulting in the
register contents being unintentionally byteswapped in certain
situations. Currently this can be triggered by the first SVE
instruction after a syscall, for example (though the potential
trigger points may vary in future).
So, fix the conversion functions fpsimd_to_sve(), sve_to_fpsimd()
and sve_sync_from_fpsimd_zeropad() to swab where appropriate.
There is no common swahl128() or swab128() that we could use here.
Maybe it would be worth making this generic, but for now add a
simple local hack.
Since the byte order differences are exposed in ABI, also clarify
the documentation.

memory.stat and other files already consider subtrees in their output, and
we should too in order to not present an inconsistent interface.
The current situation is fairly confusing, because people interacting with
cgroups expect hierarchical behaviour in the vein of memory.stat,
cgroup.events, and other files. For example, this causes confusion when
debugging reclaim events under low, as currently these always read "0" at
non-leaf memcg nodes, which frequently causes people to misdiagnose breach
behaviour. The same confusion applies to other counters in this file when
debugging issues.
Aggregation is done at write time instead of at read-time since these
counters aren't hot (unlike memory.stat which is per-page, so it does it
at read time), and it makes sense to bundle this with the file
notifications.
After this patch, events are propagated up the hierarchy:
[root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events
low 0
high 0
max 0
oom 0
oom_kill 0
[root@ktst ~]# systemd-run -p MemoryMax=1 true
Running as unit: run-r251162a189fb4562b9dabfdc9b0422f5.service
[root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events
low 0
high 0
max 7
oom 1
oom_kill 1
As this is a change in behaviour, this can be reverted to the old
behaviour by mounting with the `memory_localevents' flag set. However, we
use the new behaviour by default as there's a lack of evidence that there
are any current users of memory.events that would find this change
undesirable.
akpm: this is a behaviour change, so Cc:stable. THis is so that
forthcoming distros which use cgroup v2 are more likely to pick up the
revised behaviour.

Describe existing kernel TLS offload (added back in Linux 4.19) -
the mechanism, the expected behavior and the notable corner cases.
This documentation is mostly targeting hardware vendors who want
to implement offload, to ensure consistency between implementations.
v2:
- add emphasis around TLS_SW/TLS_HW/TLS_HW_RECORD;
- remove mentions of ongoing work (Boris);
- split the flow of data in SW vs. HW cases in TX overview
(Boris);
- call out which fields are updated by the device and which
are filled by the stack (Boris);
- move error handling into it's own section (Boris);
- add more words about fallback (Boris);
- note that checksum validation is required (Alexei);
- note that drivers shouldn't pay attention to the TLS
device features.

Pull documentation fixes from Jonathan Corbet:
"The Sphinx 2.0 release contained a few incompatible API changes that
broke our extensions and, thus, the documentation build in general.
Who knew that those deprecation warnings it was outputting actually
meant we should change something? This set of fixes makes the build
work again with Sphinx 2.0 and eliminates the warnings for 1.8. As
part of that, we also need a few fixes to the docs for places where
the new Sphinx is more strict.
It is a bit late in the cycle for this kind of change, but it does fix
problems that people are experiencing now.
There has been some talk of raising the minimum version of Sphinx we
support. I don't want to do that abruptly, though, so these changes
add some glue to continue to support versions back to 1.3. We will be
adding some infrastructure soon to nudge users of old versions
forward, with the idea of maybe increasing our minimum version (and
removing this glue) sometime in the future"

Our version check in Documentation/conf.py never envisioned a world where
Sphinx moved beyond 1.x. Now that the unthinkable has happened, fix our
version check to handle higher version numbers correctly.

The conversion of acpi/enumeration.txt to RST included one markup error,
leading to many warnings like:
.../firmware-guide/acpi/enumeration.rst:430: WARNING: Unexpected indentation.
Add the missing colon and create some peace.

Commit 13bac55ef7ae ("doc/mm: New documentation for memory performance")
added numaperf.rst, but did not add it to the TOC tree. There was also an
incorrectly marked literal block leading to this warning sequence:
numaperf.rst:24: WARNING: Unexpected indentation.
numaperf.rst:24: WARNING: Inline substitution_reference start-string without end-string.
numaperf.rst:25: WARNING: Block quote ends without a blank line; unexpected unindent.
Fix the block and add the file to the document tree.

AutoReporter is going away; recent versions of sphinx emit a warning like:
Documentation/sphinx/kerneldoc.py:125:
RemovedInSphinx20Warning: AutodocReporter is now deprecated.
Use sphinx.util.docutils.switch_source_input() instead.
Make the switch. But switch_source_input() only showed up in 1.7, so we
have to do ugly version checks to keep things working in older versions.

Recent versions of sphinx will emit messages like:
Documentation/sphinx/kerneldoc.py:103:
RemovedInSphinx20Warning: app.warning() is now deprecated.
Use sphinx.util.logging instead.
Switch to sphinx.util.logging to make this unsightly message go away.
Alas, that interface was only added in version 1.6, so we have to add a
version check to keep things working with older sphinxes.
