Substitution of "data dependency barrier" with "address-dependency
barrier" left quite a lot of lines exceeding 80 columns.
Reflow those lines as well as a few short ones not related to
the substitution.
No changes in documentation text.

The term "data dependency barrier", which has been in
memory-barriers.txt ever since it was first authored by David Howells,
has become confusing due to the fact that in LKMM's explanations.txt
and elsewhere, "data dependency" is used mostly for load-to-store data
dependency.
To prevent further confusions, do the changes listed below:
- substitute "data dependency barrier" with "address-dependency
barrier";
- add note on the removal of kernel APIs for explicit address-
dependency barriers in kernel release v5.9;
- note that address-dependency barriers are not necessary for
load-to-store situations;
- use READ_ONCE_OLD() for pre-4.15 READ_ONCE() (no implicit address-
dependency barrier);
- fix count of kernel memory barrier APIs;
- and a few more context adjustments.
Note: Cleanups of long lines are deferred to a followup patch.

Because the SLAB_TYPESAFE_BY_RCU code does not zero pages that are
to be broken up into slabs, the memory returned by kmem_cache_alloc()
must be fully initialized, including any spinlocks included in the newly
allocated structure. This means that readers attempting to look up an
SLAB_TYPESAFE_BY_RCU object must use a reference-counting approach.
A spinlock may be acquired only after a reference is obtained, which
prevents that object from being passed to kmem_struct_free(), but only
while that reference continues to be held.

This commit updates the rcu_access_pointer() advice, noting that its
return value should not be assigned to a local variable, and also noting
that there is little point in using rcu_access_pointer() within an RCU
read-side critical section.
Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
The rcu_access_pointer() macro does not consult lockdep by design because
it is intended to be used outside of RCU read-side critical sections.
This commit therefore makes a separate list for it in whatisRCU.rst.
Similarly, RCU_LOCKDEP_WARN(), rcu_sleep_check(), and RCU_NONIDLE()
do not do anything with pointer access. This commit therefore creates
a separate utility-API list for them.

The checklist.rst document advises periodic synchronize_rcu() invocations
to prevent callback flooding. However, rcu_barrier() is often a better
choice. This commit therefore adds words to this effect.
Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
The current checklist.rst file correctly notes that RCU callbacks execute
in BH context, and cannot block. This commit adds words advising people
needing callbacks to block to use workqueues, for example, by replacing
call_rcu() with queue_rcu_work().

With 'unevaluatedProperties' support implemented, there's a number of
warnings when running dtbs_check:
arch/arm64/boot/dts/renesas/r9a07g043u11-smarc.dtb: i2c@10058000: Unevaluated properties are not allowed ('resets' was unexpected)
From schema: Documentation/devicetree/bindings/i2c/renesas,riic.yaml
The main problem is that bindings schema marks resets as a required
property for RZ/G2L (and alike) SoC's but resets property is not part
of schema. So to fix this just add a resets property with maxItems
set to 1.

docs/ja_JP/SubmittingPatches: Remove reference to submitting-drivers.rst
docs: kerneldoc-preamble: Test xeCJK.sty before loading
The sequence of sections is a bit confusing here:
* we list the mux locking scheme for existing drivers before introducing
what mux locking schemes are
* we list the caveats for each locking scheme (which are tricky) before
the example of the simple use case
Restructure it entirely with the following logic:
* Intro ("I2C muxes and complex topologies")
* Locking
- mux-locked
- example
- caveats
- parent-locked
- example
- caveats
* Complex examples
* Mux type of existing device drivers
While there, also apply some other improvements:
* convert the caveat list from a table (with only one column carrying
content) to a bullet list.
* add a small introductory text to bridge the gap from listing the use
cases to telling about the hardware components to handle them and then
the device drivers that implement those.
* make empty lines usage more uniform

There are several places in the kernel where wait_on_bit is not followed
by a memory barrier (for example, in drivers/md/dm-bufio.c:new_read).
On architectures with weak memory ordering, it may happen that memory
accesses that follow wait_on_bit are reordered before wait_on_bit and
they may return invalid data.
Fix this class of bugs by introducing a new function "test_bit_acquire"
that works like test_bit, but has acquire memory ordering semantics.

A quick 'grep "5\.x" . -R' on Documentation shows that README.rst,
2.Process.rst and applying-patches.rst all mention the version number "5.x"
for kernel releases.
As the next release will be version 6.0, updating the version number to 6.x
in README.rst seems reasonable.
The description in 2.Process.rst is just a description of recent kernel
releases, it was last updated in the beginning of 2020, and can be
revisited at any time on a regular basis, independent of changing the
version number from 5 to 6. So, there is no need to update this document
now when transitioning from 5.x to 6.x numbering.
The document applying-patches.rst is probably obsolete for most users
anyway, a reader will sufficiently well understand the steps, even it
mentions version 5 rather than version 6. So, do not update that to a
version 6.x numbering scheme.
Update version number from 5.x to 6.x in README.rst only.

Originally, when there was some custom ASL needed for Linux, the
guidance for Linux-friendly OEMs was to introduced a new string in the
APCI tables and discuss it on the kernel mailing lists.
This lead to 3 strings being introduced. Those strings now have the
original problems fixed in the kernel and have since been removed.
The kernel no longer advertises any custom Linux-* _OSI strings for
OEM use.
It was discovered that these removed strings were actually being abused
to detect Linux for unrelated reasons, so drop the encouragement for
new ones to be added.

The AMU counter AMEVCNTR01 (constant counter) should increment at the same
rate as the system counter. On affected Cortex-A510 cores, AMEVCNTR01
increments incorrectly giving a significantly higher output value. This
results in inaccurate task scheduler utilization tracking and incorrect
feedback on CPU frequency.
Work around this problem by returning 0 when reading the affected counter
in key locations that results in disabling all users of this counter from
using it either for frequency invariance or as FFH reference counter. This
effect is the same to firmware disabling affected counters.
Details on how the two features are affected by this erratum:
- AMU counters will not be used for frequency invariance for affected
CPUs and CPUs in the same cpufreq policy. AMUs can still be used for
frequency invariance for unaffected CPUs in the system. Although
unlikely, if no alternative method can be found to support frequency
invariance for affected CPUs (cpufreq based or solution based on
platform counters) frequency invariance will be disabled. Please check
the chapter on frequency invariance at
Documentation/scheduler/sched-capacity.rst for details of its effect.
- Given that FFH can be used to fetch either the core or constant counter
values, restrictions are lifted regarding any of these counters
returning a valid (!0) value. Therefore FFH is considered supported
if there is a least one CPU that support AMUs, independent of any
counters being disabled or affected by this erratum. Clarifying
comments are now added to the cpc_ffh_supported(), cpu_read_constcnt()
and cpu_read_corecnt() functions.
The above is achieved through adding a new erratum: ARM64_ERRATUM_2457168.

On arm64, "rodata=full" has been suppored (but not documented) since
commit:
c55191e96c ("arm64: mm: apply r/o permissions of VM areas to its linear alias as well")
As it's necessary to determine the rodata configuration early during
boot, arm64 has an early_param() handler for this, whereas init/main.c
has a __setup() handler which is run later.
Unfortunately, this split meant that since commit:
f9a40b0890 ("init/main.c: return 1 from handled __setup() functions")
... passing "rodata=full" would result in a spurious warning from the
__setup() handler (though RO permissions would be configured
appropriately).
Further, "rodata=full" has been broken since commit:
0d6ea3ac94 ("lib/kstrtox.c: add "false"/"true" support to kstrtobool()")
... which caused strtobool() to parse "full" as false (in addition to
many other values not documented for the "rodata=" kernel parameter.
This patch fixes this breakage by:
* Moving the core parameter parser to an __early_param(), such that it
is available early.
* Adding an (optional) arch hook which arm64 can use to parse "full".
* Updating the documentation to mention that "full" is valid for arm64.
* Having the core parameter parser handle "on" and "off" explicitly,
such that any undocumented values (e.g. typos such as "ful") are
reported as errors rather than being silently accepted.
Note that __setup() and early_param() have opposite conventions for
their return values, where __setup() uses 1 to indicate a parameter was
handled and early_param() uses 0 to indicate a parameter was handled.
Fixes: f9a40b0890 ("init/main.c: return 1 from handled __setup() functions")
Fixes: 0d6ea3ac94 ("lib/kstrtox.c: add "false"/"true" support to kstrtobool()")

GCC has supported asm goto since 4.5, and Clang has since version 9.0.0.
The minimum supported versions of these tools for the build according to
Documentation/process/changes.rst are 5.1 and 11.0.0 respectively.
Remove the feature detection script, Kconfig option, and clean up some
fallback code that is no longer supported.
The removed script was also testing for a GCC specific bug that was
fixed in the 4.7 release.
Also remove workarounds for bpftrace using clang older than 9.0.0, since
other BPF backend fixes are required at this point.

can be installed/removed independently of other texlive packages.
Conditionally loading xeCJK depending only on the existence of the
"Noto Sans CJK SC" font might end up in xelatex error of
"xeCJK.sty not found!".
Improve the situation by testing existence of xeCJK.sty before

This is useful on RHEL 9 and its clone distros where texlive-xecjk
doesn't work at the moment due to a missing dependency [1].
"make pdfdocs" for non-CJK contents should work after removing

regulator: core: Fix missing error return from regulator_bulk_get()
regulator: pca9450: Remove restrictions for regulator-name
These operations are documented as always ordered in
include/asm-generic/bitops/instrumented-atomic.h, and producer-consumer
type use cases where one side needs to ensure a flag is left pending
after some shared data was updated rely on this ordering, even in the
failure case.
This is the case with the workqueue code, which currently suffers from a
reproducible ordering violation on Apple M1 platforms (which are
notoriously out-of-order) that ends up causing the TTY layer to fail to
deliver data to userspace properly under the right conditions. This
change fixes that bug.
Change the documentation to restrict the "no order on failure" story to
the _lock() variant (for which it makes sense), and remove the
early-exit from the generic implementation, which is what causes the
missing barrier semantics in that case. Without this, the remaining
atomic op is fully ordered (including on ARM64 LSE, as of recent
versions of the architecture spec).

When the thermal zone description was converted to yaml schema, the
required 'trips' property was forgotten.
The initial text bindings was describing:
"
[ ... ]
* Thermal zone nodes
The thermal zone node is the node containing all the required info
for describing a thermal zone, including its cooling device bindings. The
thermal zone node must contain, apart from its own properties, one sub-node
containing trip nodes and one sub-node containing all the zone cooling maps.
Required properties:
- polling-delay: The maximum number of milliseconds to wait between polls
Type: unsigned when checking this thermal zone.
Size: one cell
- polling-delay-passive: The maximum number of milliseconds to wait
Type: unsigned between polls when performing passive cooling.
Size: one cell
- thermal-sensors: A list of thermal sensor phandles and sensor specifier
Type: list of used while monitoring the thermal zone.
phandles + sensor
specifier
- trips: A sub-node which is a container of only trip point nodes
Type: sub-node required to describe the thermal zone.
Optional property:
- cooling-maps: A sub-node which is a container of only cooling device
Type: sub-node map nodes, used to describe the relation between trips
and cooling devices.
[ ... ]
"
Now the schema describes:
"
[ ... ]
required:
- polling-delay
- polling-delay-passive
- thermal-sensors
[ ... ]
"
Add the missing 'trips' property in the required properties.

In some use cases[1], the backend is created while the frontend doesn't
support the persistent grants feature, but later the frontend can be
changed to support the feature and reconnect. In the past, 'blkback'
enabled the persistent grants feature since it unconditionally checked
if frontend supports the persistent grants feature for every connect
('connect_ring()') and decided whether it should use persistent grans or
not.
However, commit aac8a70db2 ("xen-blkback: add a parameter for
disabling of persistent grants") has mistakenly changed the behavior.
It made the frontend feature support check to not be repeated once it
shown the 'feature_persistent' as 'false', or the frontend doesn't
support persistent grants.
Similar behavioral change has made on 'blkfront' by commit 74a852479c
("xen-blkfront: add a parameter for disabling of persistent grants").
This commit changes the behavior of the parameter to make effect for
every connect, so that the previous behavior of 'blkfront' can be
restored.

Fix device tree schema validation error messages for the SiFive
Unmatched: ' cache-sets:0:0: 1024 was expected'.
The existing bindings allow for just 1024 cache-sets but the fu740 on
Unmatched the has 2048 cache-sets. The ISA itself permits any arbitrary
power of two, however this is not supported by dt-schema. The RTL for
the IP, to which the number of cache-sets is a tunable parameter, has
been released publicly so speculatively adding a small number of
"reasonable" values seems unwise also.
Instead, as the binding only supports two distinct controllers: add 2048
and explicitly lock it to the fu740's l2 cache while limiting 1024 to
the l2 cache on the fu540.

A little longer PR than usual but it's all fixes, no late features.
It's long partially because of timing, and partially because of
follow ups to stuff that got merged a week or so before the merge
window and wasn't as widely tested. Maybe the Bluetooth fixes are
a little alarming so we'll address that, but the rest seems okay
and not scary.
Notably we're including a fix for the netfilter Kconfig [1], your
WiFi warning [2] and a bluetooth fix which should unblock syzbot [3].
Current release - regressions:
- Bluetooth:
- don't try to cancel uninitialized works [3]
- L2CAP: fix use-after-free caused by l2cap_chan_put
- tls: rx: fix device offload after recent rework
- devlink: fix UAF on failed reload and leftover locks in mlxsw
Current release - new code bugs:
- netfilter:
- flowtable: fix incorrect Kconfig dependencies [1]
- nf_tables: fix crash when nf_trace is enabled
- bpf:
- use proper target btf when exporting attach_btf_obj_id
- arm64: fixes for bpf trampoline support
- Bluetooth:
- ISO: unlock on error path in iso_sock_setsockopt()
- ISO: fix info leak in iso_sock_getsockopt()
- ISO: fix iso_sock_getsockopt for BT_DEFER_SETUP
- ISO: fix memory corruption on iso_pinfo.base
- ISO: fix not using the correct QoS
- hci_conn: fix updating ISO QoS PHY
- phy: dp83867: fix get nvmem cell fail
Previous releases - regressions:
- wifi: cfg80211: fix validating BSS pointers in
__cfg80211_connect_result [2]
- atm: bring back zatm uAPI after ATM had been removed
- properly fix old bug making bonding ARP monitor mode not being
able to work with software devices with lockless Tx
- tap: fix null-deref on skb->dev in dev_parse_header_protocol
- revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP" it helps
some devices and breaks others
- netfilter:
- nf_tables: many fixes rejecting cross-object linking
which may lead to UAFs
- nf_tables: fix null deref due to zeroed list head
- nf_tables: validate variable length element extension
- bgmac: fix a BUG triggered by wrong bytes_compl
- bcmgenet: indicate MAC is in charge of PHY PM
Previous releases - always broken:
- bpf:
- fix bad pointer deref in bpf_sys_bpf() injected via test infra
- disallow non-builtin bpf programs calling the prog_run command
- don't reinit map value in prealloc_lru_pop
- fix UAFs during the read of map iterator fd
- fix invalidity check for values in sk local storage map
- reject sleepable program for non-resched map iterator
- mptcp:
- move subflow cleanup in mptcp_destroy_common()
- do not queue data on closed subflows
- virtio_net: fix memory leak inside XDP_TX with mergeable
- vsock: fix memory leak when multiple threads try to connect()
- rework sk_user_data sharing to prevent psock leaks
- geneve: fix TOS inheriting for ipv4
- tunnels & drivers: do not use RT_TOS for IPv6 flowlabel
- phy: c45 baset1: do not skip aneg configuration if clock role
is not specified
- rose: avoid overflow when /proc displays timer information
- x25: fix call timeouts in blocking connects
- can: mcp251x: fix race condition on receive interrupt
- can: j1939:
- replace user-reachable WARN_ON_ONCE() with netdev_warn_once()
- fix memory leak of skbs in j1939_session_destroy()
Misc:
- docs: bpf: clarify that many things are not uAPI
- seg6: initialize induction variable to first valid array index
(to silence clang vs objtool warning)
- can: ems_usb: fix clang 14's -Wunaligned-access warning

changes:
1. Add address/size-cells.
2. Describe the clocks per variant.
3. Use more descriptive example based on sdm845.

There is unexpected warning on KVM_CAP_VM_DISABLE_NX_HUGE_PAGES capability
table, which cause the table to be rendered as paragraph text instead.
The warning is due to missing colon at capability name and returns keyword,
as well as improper alignment on multi-line returns field.
Fix the warning by adding missing colons and aligning the field.

This series is based on the alternatives changes done in my svpbmt
series and thus also depends on Atish's isa-extension parsing series.
It implements using the cache-management instructions from the Zicbom-
extension to handle cache flush, etc actions on platforms needing them.
SoCs using cpu cores from T-Head like the Allwinne D1 implement a
different set of cache instructions. But while they are different,
instructions they provide the same functionality, so a variant can easly
hook into the existing alternatives mechanism on those.
[Palmer: Some minor fixups, including a RISCV_ISA_ZICBOM dependency on
MMU that's probably not strictly necessary. The Zicbom support will
trip up sparse for users that have new toolchains, I just sent a patch.]

Work on "courteous server", which was introduced in 5.19, continues
apace. This release introduces a more flexible limit on the number
of NFSv4 clients that NFSD allows, now that NFSv4 clients can remain
in courtesy state long after the lease expiration timeout. The
client limit is adjusted based on the physical memory size of the
server.
The NFSD filecache is a cache of files held open by NFSv4 clients or
recently touched by NFSv2 or NFSv3 clients. This cache had some
significant scalability constraints that have been relieved in this
release. Thanks to all who contributed to this work.
A data corruption bug found during the most recent NFS bake-a-thon
that involves NFSv3 and NFSv4 clients writing the same file has been
addressed in this release.
This release includes several improvements in CPU scalability for
NFSv4 operations. In addition, Neil Brown provided patches that
simplify locking during file lookup, creation, rename, and removal
that enables subsequent work on making these operations more
scalable. We expect to see that work materialize in the next
release.
There are also numerous single-patch fixes, clean-ups, and the
usual improvements in observability.

recently touched by NFSv2 or NFSv3 clients. This cache had some
significant scalability constraints that have been relieved in this
release. Thanks to all who contributed to this work.
A data corruption bug found during the most recent NFS bake-a-thon
that involves NFSv3 and NFSv4 clients writing the same file has been
addressed in this release.
This release includes several improvements in CPU scalability for
NFSv4 operations. In addition, Neil Brown provided patches that
simplify locking during file lookup, creation, rename, and removal
that enables subsequent work on making these operations more scalable.
We expect to see that work materialize in the next release.
There are also numerous single-patch fixes, clean-ups, and the usual
improvements in observability"

What happens if a thread is preempted after mapping pages with
kmap_local_page() was questioned recently.[1]
Commit f3ba3c710a ("mm/highmem: Provide kmap_local*") from Thomas
Gleixner explains clearly that on context switch, the maps of an outgoing
task are removed and the map of the incoming task are restored and that
kmap_local_page() can be invoked from both preemptible and atomic
contexts.[2]
Therefore, for the purpose to make it clearer that users can call
kmap_local_page() from contexts that allow preemption, rework a couple of
sentences and add further information in highmem.rst.

The reasoning for converting kmap() to kmap_local_page() was questioned
recently.[1]
There are two main problems with kmap(): (1) It comes with an overhead as
mapping space is restricted and protected by a global lock for
synchronization and (2) kmap() also requires global TLB invalidation when
its pool wraps and it might block when the mapping space is fully utilized
until a slot becomes available.
Warn users to avoid the use of kmap() and instead use kmap_local_page(),
by designing their code to map pages in the same context the mapping will
be used.

Users of kmap_local_page() must be absolutely sure to not hand kernel
virtual address obtained calling kmap_local_page() on highmem pages to
other contexts because those pointers are thread local, therefore, they
are no longer valid across different contexts.
Extend the documentation of kmap_local_page() to warn users about the
above-mentioned potential invalid use of pointers returned by
kmap_local_page().

There is no need to kmap*() pages which are guaranteed to come from
ZONE_NORMAL (or lower). Linux has currently several call sites of
kmap{,_atomic,_local_page}() on pages which are clearly known which can't
come from ZONE_HIGHMEM.
Therefore, add a paragraph to highmem.rst, to explain better that a plain
page_address() may be used for getting the address of pages which cannot
come from ZONE_HIGHMEM, although it is always safe to use
kmap_local_page() / kunmap_local() also on those pages.

It it inconvenient to mention the feature of optimizing vmemmap pages
associated with HugeTLB pages when communicating with others since there
is no specific or abbreviated name for it when it is first introduced.
Let us give it a name HVO (HugeTLB Vmemmap Optimization) from now.
This commit also updates the document about "hugetlb_free_vmemmap" by the
way discussed in thread [1].

This introduces support for the remoteproc on Mediatek MT8188, and
enables caches for MT8186 SCP. It adds support for PRU cores found on
the TI K3 AM62x SoCs.
It moves the recovery work after a firmware crash to an unbound
workqueue, to allow recovery to happen in parallel.
A new DMA API is introduced to release dma_mem for a device.
It adds support a panic handler for the Qualcomm modem remoteproc, with
the goal of having caches flushed in memory dumps for post-mortem
debugging and it introduces a mechanism to wait for the modem firmware
on SM8450 to decrypt part of its memory for post-mortem debugging.
Qualcomm sysmon is restricted to only inform remote processors about
peers that are actually running, to avoid a race where Linux tries to
notify a recovering remote processor about its peers new state. A
mechanism for waiting for the sysmon connection to be established is also
introduced, to avoid out-of-sync updates for rapidly restarting remote
processors.
A number of Devicetree binding cleanups and conversions to YAML are
introduced, to facilitate Devicetree validation. Lastly it introduces a
number of smaller fixes and cleanups in the core and a few different
drivers.

For the 6.0 merge window the modules code shifts to cleanup and minor fixes
effort. This is becomes much easier to do and review now due to the code
split to its own directory from effort on the last kernel release. I expect
to see more of this with time and as we expand on test coverage in the future.
The cleanups and fixes come from usual suspects such as Christophe Leroy and
Aaron Tomlin but there are also some other contributors.
One particular minor fix worth mentioning is from Helge Deller, where he spotted
a *forever* incorrect natural alignment on both ELF section header tables:
* .altinstructions
* __bug_table sections
A lot of back and forth went on in trying to determine the ill effects of this
misalignment being present for years and it has been determined there should
be no real ill effects unless you have a buggy exception handler. Helge actually
hit one of these buggy exception handlers on parisc which is how he ended up
spotting this issue. When implemented correctly these paths with incorrect
misalignment would just mean a performance penalty, but given that we are
dealing with alternatives on modules and with the __bug_table (where info
regardign BUG()/WARN() file/line information associated with it is stored)
this really shouldn't be a big deal.
The only other change with mentioning is the kmap() with kmap_local_page()
and my only concern with that was on what is done after preemption, but the
virtual addresses are restored after preemption. This is only used on module
decompression.
This all has sit on linux-next for a while except the kmap stuff which has
been there for 3 weeks.

Here is the big set of tty and serial driver changes for 6.0-rc1.
It was delayed from last week as I wanted to make sure the last commit
here got some good testing in linux-next and elsewhere as it seemed to
show up only late in testing for some reason.
Nothing major here, just lots of cleanups from Jiri and Ilpo to make the
tty core cleaner (Jiri) and the rs485 code simpler to use (Ilpo). Also
included in here is the obligatory n_gsm updates from Daniel Starke and
lots of tiny driver updates and minor fixes and tweaks for other smaller
serial drivers.
Full details are in the shortlog.
All of these have been in linux-next for a while with no reported
problems.

In this cycle, we mainly fixed some corner cases that manipulate a per-file
compression flag inappropriately. And, we found f2fs counted valid blocks in a
section incorrectly when zone capacity is set, and thus, fixed it with
additional sysfs entry to check it easily. Lastly, this series includes
several patches with respect to the new atomic write support such as a
couple of bug fixes and re-adding atomic_write_abort support that we removed
by mistake in the previous release.
Enhancement:
- add sysfs entries to understand atomic write operations and zone
capacity
- introduce memory mode to get a hint for low-memory devices
- adjust the waiting time of foreground GC
- decompress clusters under softirq to avoid non-deterministic latency
- do not skip updating inode when retrying to flush node page
- enforce single zone capacity
Bug fix:
- set the compression/no-compression flags correctly
- revive F2FS_IOC_ABORT_VOLATILE_WRITE
- check inline_data during compressed inode conversion
- understand zone capacity when calculating valid block count
As usual, the series includes several minor clean-ups and sanity checks.

AMD's "Technical Guidance for Mitigating Branch Type Confusion,
Rev. 1.0 2022-07-12" whitepaper, under section 6.1.2 "IBPB On
Privileged Mode Entry / SMT Safety" says:
Similar to the Jmp2Ret mitigation, if the code on the sibling thread
cannot be trusted, software should set STIBP to 1 or disable SMT to
ensure SMT safety when using this mitigation.
So, like already being done for retbleed=unret, and now also for
retbleed=ibpb, force STIBP on machines that have it, and report its SMT
vulnerability status accordingly.
[ bp: Remove the "we" and remove "[AMD]" applicability parameter which
doesn't work here. ]

The two major changes in this patchset corrects VGA modes, color
handling and various other smaller fixes in the Atari framebuffer (by
Geert Uytterhoeven), and devm_* conversion, platform data fixes and
header cleanups in the imxfb driver (by Uwe Kleine-König).
Other small patches clean up code in sa1100fb, cirrusfb and omapfb,
fix a refcount leak in amba-clcd (by Liang He), and adds parameter
checks to arkfb, i740fb, vt8623fb and s3fb (by Zheyu Ma).

- Rework copy_oldmem_page() callback to take an iov_iter.
This includes few prerequisite updates and fixes to the
oldmem reading code.
- Rework cpufeature implementation to allow for various CPU feature
indications, which is not only limited to hardware capabilities,
but also allows CPU facilities.
- Use the cpufeature rework to autoload Ultravisor module when CPU
facility 158 is available.
- Add ELF note type for encrypted CPU state of a protected virtual CPU.
The zgetdump tool from s390-tools package will decrypt the CPU state
using a Customer Communication Key and overwrite respective notes to
make the data accessible for crash and other debugging tools.
- Use vzalloc() instead of vmalloc() + memset() in ChaCha20 crypto test.
- Fix incorrect recovery of kretprobe modified return address in stacktrace.
- Switch the NMI handler to use generic irqentry_nmi_enter() and
irqentry_nmi_exit() helper functions.
- Rework the cryptographic Adjunct Processors (AP) pass-through design
to support dynamic changes to the AP matrix of a running guest as well
as to implement more of the AP architecture.
- Minor boot code cleanups.
- Grammar and typo fixes to hmcdrv and tape drivers.

- Most intrusive patch is small and changes the default
allocation policy for DMA addresses. Before the change the
allocator tried its best to find an address in the first 4GB.
But that lead to performance problems when that space gets
exhaused, and since most devices are capable of 64-bit DMA
these days, we changed it to search in the full DMA-mask
range from the beginning. This change has the potential to
uncover bugs elsewhere, in the kernel or the hardware. There
is a Kconfig option and a command line option to restore the
old behavior, but none of them is enabled by default.

As diffstat shows, we've had lots of developments in a wide range
at this time; the majority of changes are about ASoC, including
subsystem-wide cleanups, continued SOF / Intel updates and a
bunch of new drivers (as usual), while there have been some
significant (but almost invisible) improvements in ALSA core
side, too. Below are some highlights:
Core:
- Faster lookups of control elements with Xarray; normal user
won't notice, but on the devices with tons of control elements,
it can be visibly faster
- Support for input validation for controls; this will harden
for badly written drivers in general with a slight overhead
- Deferred async signal handling for working around the potential
deadlocks
- Cleanup / refactoring raw MIDI locking code
ASoC:
- Restructing of the set_fmt() callbacks for making things clearer
in situations like CODEC to CODEC links
- Clean up and modernizing the DAI naming scheme setups
- Merge of more of the Intel AVS driver stack, including some
board integrations
- New version 4 mechanism for communication with SOF DSPs
- Suppoort for dynamically selecting the PLL to use at runtime on
i.MX platforms
- Improvements for CODEC to CODEC support in the generic cards
- Support for AMD Jadeite and various machines, AMD RPL, Intel
MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and
WAS883x, and Texas Instruments TAS2780
HD- and USB-audio:
- Continued improvement for CS35L41 (sub)codec support
- More quirks for various devices (HP, Lenovo, Dell, Clevo)

Liam's maple tree rework didn't make it. This has resulted in a few
other minor patch series being held over for next time.
Multi-gen LRU still isn't merged as we were waiting for mapletree to
stabilize. The current plan is to merge MGLRU into -mm soon and to
later reintroduce mapletree, with a view to hopefully getting both
into 6.1-rc1.
