Merge tag 'coccinelle-for-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/jlawall/linux
Pull coccinelle semantic patch updates from Julia Lawall:
- Update the semantic patches in the kernel that contain a URL for
Coccinelle with a URL that is currently valid (from myself).
- Add a semantic patch checking for unnecessary NULL tests on dev_{put,
hold} functions (from Ziyang Xuan, followed bt a modification from
myself).
- Drop a semantic patch that replaces 0/1 by booleans, as this change
was considered to be not worthwhile by some maintainers (from Steve
Rostedt).
- Extend an existing semantic patch with more checks for useless tests
on variables addresses (from Jérémy Lefaure).
* tag 'coccinelle-for-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/jlawall/linux:
update Coccinelle URL
coccinelle: free: add version constraint
scripts/coccinelle/free: add NULL test before dev_{put, hold} functions

Pull more device mapper updates from Mike Snitzer: - Add flags argument to dm_bufio_client_create and introduce DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather than mutex for its locking. - Add optional "try_verify_in_tasklet" feature to DM verity target. This feature gives users the option to improve IO latency by using a tasklet to verify, using hashes in bufio's cache, rather than wait to schedule a work item via workqueue. But if there is a bufio cache miss, or an error, then the tasklet will fallback to using workqueue. - Incremental changes to both dm-bufio and the DM verity target to use jump_label to minimize cost of branching associated with the niche "try_verify_in_tasklet" feature. DM-bufio in particular is used by quite a few other DM targets so it doesn't make sense to incur additional bufio cost in those targets purely for the benefit of this niche verity feature if the feature isn't ever used. - Optimize verity_verify_io, which is used by both workqueue and tasklet based verification, if FEC is not configured or tasklet based verification isn't used. - Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE flag since it uses WQ_UNBOUND.

Merge tag 'iommu-updates-v5.20-or-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
- The 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.
- Add Robin Murphy as reviewer of IOMMU code and maintainer for the
dma-iommu and iova code
- Chaning IOVA magazine size from 1032 to 1024 bytes to save memory
- Some core code cleanups and dead-code removal
- Support for ACPI IORT RMR node
- Support for multiple PCI domains in the AMD-Vi driver
- ARM SMMU changes from Will Deacon:
- Add even more Qualcomm device-tree compatible strings
- Support dumping of IMP DEF Qualcomm registers on TLB sync
timeout
- Fix reference count leak on device tree node in Qualcomm driver
- Intel VT-d driver updates from Lu Baolu:

Merge tag 'sound-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"As the 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)"

Merge tag 'perf-tools-for-v6.0-2022-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tools updates from Arnaldo Carvalho de Melo:
- Introduce 'perf lock contention' subtool, using new lock contention
tracepoints and using BPF for in kernel aggregation and then
userspace processing using the perf tooling infrastructure for
resolving symbols, target specification, etc.
Since the new lock contention tracepoints don't provide lock names,
get up to 8 stack traces and display the first non-lock function
symbol name as a caller:
$ perf lock report -F acquired,contended,avg_wait,wait_total
Name acquired contended avg wait total wait
update_blocked_a... 40 40 3.61 us 144.45 us
kernfs_fop_open+... 5 5 3.64 us 18.18 us
_nohz_idle_balance 3 3 2.65 us 7.95 us
tick_do_update_j... 1 1 6.04 us 6.04 us
ep_scan_ready_list 1 1 3.93 us 3.93 us
Supports the usual 'perf record' + 'perf report' workflow as well as
a BCC/bpftrace like mode where you start the tool and then press
control+C to get results:
$ sudo perf lock contention -b
^C
contended total wait max wait avg wait type caller

- Add new 'perf kwork' tool to trace time properties of kernel work
(such as softirq, and workqueue), uses eBPF skeletons to collect info
in kernel space, aggregating data that then gets processed by the
userspace tool, e.g.:
# perf kwork report

See commit log messages for more examples with extra options to limit
the events time window, etc.
- Add support for new AMD IBS (Instruction Based Sampling) features:
With the DataSrc extensions, the source of data can be decoded among:
- Local L3 or other L1/L2 in CCX.
- A peer cache in a near CCX.
- Data returned from DRAM.
- A peer cache in a far CCX.
- DRAM address map with "long latency" bit set.
- Data returned from MMIO/Config/PCI/APIC.
- Extension Memory (S-Link, GenZ, etc - identified by the CS target
and/or address map at DF's choice).
- Peer Agent Memory.
- Support hardware tracing with Intel PT on guest machines, combining
the traces with the ones in the host machine.
- Add a "-m" option to 'perf buildid-list' to show kernel and modules
build-ids, to display all of the information needed to do external
symbolization of kernel stack traces, such as those collected by
bpf_get_stackid().
- Add arch TSC frequency information to perf.data file headers.
- Handle changes in the binutils disassembler function signatures in
perf, bpftool and bpf_jit_disasm (Acked by the bpftool maintainer).
- Fix building the perf perl binding with the newest gcc in distros
such as fedora rawhide, where some new warnings were breaking the
build as perf uses -Werror.
- Add 'perf test' entry for branch stack sampling.
- Add ARM SPE system wide 'perf test' entry.
- Add user space counter reading tests to 'perf test'.
- Build with python3 by default, if available.
- Add python converter script for the vendor JSON event files.
- Update vendor JSON files for most Intel cores.
- Add vendor JSON File for Intel meteorlake.
- Add Arm Cortex-A78C and X1C JSON vendor event files.
- Add workaround to symbol address reading from ELF files without phdr,
falling back to the previoous equation.
- Convert legacy map definition to BTF-defined in the perf BPF script
test.
- Rework prologue generation code to stop using libbpf deprecated APIs.
- Add default hybrid events for 'perf stat' on x86.
- Add topdown metrics in the default 'perf stat' on the hybrid machines
(big/little cores).
- Prefer sampled CPU when exporting JSON in 'perf data convert'
- Fix ('perf stat CSV output linter') and ("Check branch stack
sampling") 'perf test' entries on s390.
