Currently the pinctrl GPIO helpers all take a number from the global
GPIO numberspace - of which we're trying to get rid of as argument.
These helpers are almost universally called from GPIOLIB driver
callbacks which take a pointer to the backing gpio_chip and the
controller-relative offset as arguments.
Let's provide improved variants of these functions that match the
GPIOLIB signatures as the first step in removing the older flavor.

Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
Nothing really major in here, just lots of constant development for new
hardware. Included in here are:
- Thunderbolt (i.e. USB4) fixes for reported issues and support for
new hardware types and devices
- USB typec additions of new drivers and cleanups for some existing
ones
- xhci cleanups and expanded tracing support and some platform
specific updates
- USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio, spi,
and i2c drivers for that type of device (all acked by the respective
subsystem maintainers.)
- lots of USB gadget driver updates and cleanups
- new USB dwc3 platforms supported, as well as other dwc3 fixes and
cleanups
- USB chipidea driver updates
- other smaller driver cleanups and additions, full details in the
shortlog
All of these have been in the linux-next tree for a while with no
reported problems, EXCEPT for some merge conflicts that you will run
into in your tree. 2 of them are in device-tree files, which will be
trivial to resolve (accept both sides), and the last in the
drivers/gpio/gpio-ljca.c file, in the remove callback, resolution should
be pretty trivial (take the version in this branch), see here:
https://lore.kernel.org/all/20231016134159.11d8f849@canb.auug.org.au/
for details, or I can provide a resolved merge point if needed.

Here is the big set of staging driver updates for 6.7-rc1. A bit bigger
than 6.6 this time around, as it coincided with the Outreachy and
mentorship application process, so we got a bunch of new developers
sending in their first changes, which is nice to see.
Also in here is a removal of the qlge ethernet driver, and the rtl8192u
wireless driver. Both of these were very old and no one was maintaining
them, the wireless driver removal was due to no one using it anymore,
and no hardware to be found, and is part of a larger effort to remove
unused and old wifi drivers from the system.
The qlge ethernet driver did have one user pop up after it was dropped,
and we are working with the network mainainers to figure out what tree
it will come back in from and who will be responsible for it, and if it
really is being used or not. Odds are it will show up in a network
subsystem pull request after -rc1 is out, but we aren't sure yet.
Other smaller changes in here are:
- Lots of vc04_services work by Umang to clean up the mess created by
the rpi developers long ago, bringing it almost into good enough
shape to get out of staging, hopefully next major release, it's
getting close.
- rtl8192e variable cleanups and removal of unused code and structures
- vme_user coding style cleanups
- other small coding style cleanups to lots of the staging drivers
- octeon typedef removals, and then last-minute revert when it was
found to break the build in some configurations (it's a hard driver
to build properly, none of the normal automated testing catches it.)
All of these have been in linux-next for a while with no reported
issues.

the code (fixing comments, removing now dead functions, and macros
etc). Finally there are 4 bug fixes, with the regression fix having
had a couple months of testing.
Features:

Merge tag 'landlock-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux
Pull landlock updates from Mickaël Salaün:
"A Landlock ruleset can now handle two new access rights:
LANDLOCK_ACCESS_NET_BIND_TCP and LANDLOCK_ACCESS_NET_CONNECT_TCP. When
handled, the related actions are denied unless explicitly allowed by a
Landlock network rule for a specific port.
The related patch series has been reviewed for almost two years, it
has evolved a lot and we now have reached a decent design, code and
testing. The refactored kernel code and the new test helpers also
bring the foundation to support more network protocols.
Test coverage for security/landlock is 92.4% of 710 lines according to
gcc/gcov-13, and it was 93.1% of 597 lines before this series. The
decrease in coverage is due to code refactoring to make the ruleset
management more generic (i.e. dealing with inodes and ports) that also
added new WARN_ON_ONCE() checks not possible to test from user space.
syzkaller has been updated accordingly [4], and such patched instance
(tailored to Landlock) has been running for a month, covering all the
new network-related code [5]"

Build
-----
* Compile BPF programs by default if clang (>= 12.0.1) is available to
enable more features like kernel lock contention, off-cpu profiling,
kwork, sample filtering and so on. It can be disabled by passing
BUILD_BPF_SKEL=0 to make.
* Produce better error messages for bison on debug build (make DEBUG=1)
by defining YYDEBUG symbol internally.
perf record
-----------
* Track sideband events (like FORK/MMAP) from all CPUs even if perf record
targets a subset of CPUs only (using -C option). Otherwise it may lose
some information happened on a CPU out of the target list.
* Fix checking raw sched_switch tracepoint argument using system BTF.
This affects off-cpu profiling which attaches a BPF program to the raw
tracepoint.
perf lock contention
--------------------
* Add --lock-cgroup option to see contention by cgroups. This should be
used with BPF only (using -b option).
$ sudo perf lock con -ab --lock-cgroup -- sleep 1
contended total wait max wait avg wait cgroup
835 14.06 ms 41.19 us 16.83 us /system.slice/led.service
25 122.38 us 13.77 us 4.89 us /
44 23.73 us 3.87 us 539 ns /user.slice/user-657345.slice/session-c4.scope
1 491 ns 491 ns 491 ns /system.slice/connectd.service
* Add -G/--cgroup-filter option to see contention only for given cgroups.
This can be useful when you identified a cgroup in the above command and
want to investigate more on it. It also works with other output options
like -t/--threads and -l/--lock-addr.
$ sudo perf lock con -ab -G /user.slice/user-657345.slice/session-c4.scope -- sleep 1
contended total wait max wait avg wait type caller
8 77.11 us 17.98 us 9.64 us spinlock futex_wake+0xc8
2 24.56 us 14.66 us 12.28 us spinlock tick_do_update_jiffies64+0x25
1 4.97 us 4.97 us 4.97 us spinlock futex_q_lock+0x2a
* Use per-cpu array for better spinlock tracking. This is to improve
performance of the BPF program and to avoid nested contention on a lock
in the BPF hash map.
* Update callstack check for PowerPC. To find a representative caller of a
lock, it needs to look up the call stacks. It ends the lookup when it sees
0 in the call stack buffer. However, PowerPC call stacks can have 0 values
in the beginning so skip them when it expects valid call stacks after.
perf kwork
----------
* Support 'sched' class (for -k option) so that it can see task scheduling
event (using sched_switch tracepoint) as well as irq and workqueue items.
* Add perf kwork top subcommand to show more accurate cpu utilization with
sched class above. It works both with a recorded data (using perf kwork
record command) and BPF (using -b option). Unlike perf top command, it
does not support interactive mode (yet).
$ sudo perf kwork top -b -k sched

perf bench
----------
* Add -G/--cgroups option to perf bench sched pipe. The pipe bench is
good to measure context switch overhead. With this option, it puts
the reader and writer tasks in separate cgroups to enforce context
switch between two different cgroups.
Also it needs to set CPU affinity of the tasks in a CPU to accurately
measure the impact of cgroup context switches.
$ sudo perf stat -e context-switches,cgroup-switches -- \
> taskset -c 0 perf bench sched pipe -l 100000
# Running 'sched/pipe' benchmark:
# Executed 100000 pipe operations between two processes
Total time: 0.307 [sec]
3.078180 usecs/op
324867 ops/sec
Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000':
200,026 context-switches
63 cgroup-switches
0.321637922 seconds time elapsed
You can see small number of cgroup-switches because both write and read
tasks are in the same cgroup.
$ sudo mkdir /sys/fs/cgroup/{AAA,BBB}
$ sudo perf stat -e context-switches,cgroup-switches -- \
> taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB
# Running 'sched/pipe' benchmark:
# Executed 100000 pipe operations between two processes
Total time: 0.351 [sec]
3.512990 usecs/op
284657 ops/sec
Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB':
200,020 context-switches
200,019 cgroup-switches
0.365034567 seconds time elapsed
Now context-switches and cgroup-switches are almost same. And you can
see the pipe operation took little more.
* Kill child processes when perf bench sched messaging exited abnormally.
Otherwise it'd leave the child doing unnecessary work.
perf test
---------
* Fix various shellcheck issues on the tests written in shell script.
* Skip tests when condition is not satisfied:
- object code reading test for non-text section addresses.
- CoreSight test if cs_etm// event is not available.
- lock contention test if not enough CPUs.
Event parsing
-------------
* Make PMU alias name loading lazy to reduce the startup time in the
event parsing code for perf record, stat and others in the general
case.
* Lazily compute PMU default config. In the same sense, delay PMU
initialization until it's really needed to reduce the startup cost.
* Fix event term values that are raw events. The event specification
can have several terms including event name. But sometimes it clashes
with raw event encoding which starts with 'r' and has hex-digits.
For example, an event named 'read' should be processed as a normal
event but it was mis-treated as a raw encoding and caused a failure.
$ perf stat -e 'uncore_imc_free_running/event=read/' -a sleep 1
event syntax error: '..nning/event=read/'
\___ parser error
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event> event selector. use 'perf list' to list available events
Event metrics
-------------
* Add "Compat" regex to match event with multiple identifiers.
* Usual updates for Intel, Power10, Arm telemetry/CMN and AmpereOne.
Misc
----
* Assorted memory leak fixes and footprint reduction.
* Add "bpf_skeletons" to perf version --build-options so that users can
check whether their perf tools have BPF support easily.
* Fix unaligned access in Intel-PT packet decoder found by undefined-behavior
sanitizer.
* Avoid frequency mode for the dummy event. Surprisingly it'd impact
kernel timer tick handler performance by force iterating all PMU events.
* Update bash shell completion for events and metrics.

Merge tag 'perf-tools-for-v6.7-1-2023-11-01' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
Pull perf tools updates from Namhyung Kim:
"Build:
- Compile BPF programs by default if clang (>= 12.0.1) is available
to enable more features like kernel lock contention, off-cpu
profiling, kwork, sample filtering and so on.
This can be disabled by passing BUILD_BPF_SKEL=0 to make.
- Produce better error messages for bison on debug build (make
DEBUG=1) by defining YYDEBUG symbol internally.
perf record:
- Track sideband events (like FORK/MMAP) from all CPUs even if perf
record targets a subset of CPUs only (using -C option). Otherwise
it may lose some information happened on a CPU out of the target
list.
- Fix checking raw sched_switch tracepoint argument using system BTF.
This affects off-cpu profiling which attaches a BPF program to the
raw tracepoint.
perf lock contention:
- Add --lock-cgroup option to see contention by cgroups. This should
be used with BPF only (using -b option).
$ sudo perf lock con -ab --lock-cgroup -- sleep 1
contended total wait max wait avg wait cgroup
835 14.06 ms 41.19 us 16.83 us /system.slice/led.service
25 122.38 us 13.77 us 4.89 us /
44 23.73 us 3.87 us 539 ns /user.slice/user-657345.slice/session-c4.scope
1 491 ns 491 ns 491 ns /system.slice/connectd.service
- Add -G/--cgroup-filter option to see contention only for given
cgroups.
This can be useful when you identified a cgroup in the above
command and want to investigate more on it. It also works with
other output options like -t/--threads and -l/--lock-addr.
$ sudo perf lock con -ab -G /user.slice/user-657345.slice/session-c4.scope -- sleep 1
contended total wait max wait avg wait type caller
8 77.11 us 17.98 us 9.64 us spinlock futex_wake+0xc8
2 24.56 us 14.66 us 12.28 us spinlock tick_do_update_jiffies64+0x25
1 4.97 us 4.97 us 4.97 us spinlock futex_q_lock+0x2a
- Use per-cpu array for better spinlock tracking. This is to improve
performance of the BPF program and to avoid nested contention on a
lock in the BPF hash map.
- Update callstack check for PowerPC. To find a representative caller
of a lock, it needs to look up the call stacks. It ends the lookup
when it sees 0 in the call stack buffer. However, PowerPC call
stacks can have 0 values in the beginning so skip them when it
expects valid call stacks after.
perf kwork:
- Support 'sched' class (for -k option) so that it can see task
scheduling event (using sched_switch tracepoint) as well as irq and
workqueue items.
- Add perf kwork top subcommand to show more accurate cpu utilization
with sched class above. It works both with a recorded data (using
perf kwork record command) and BPF (using -b option). Unlike perf
top command, it does not support interactive mode (yet).
$ sudo perf kwork top -b -k sched

- Remove eventfs_file descriptor
This is the biggest change, and the second part of making eventfs
create its files dynamically.
In 6.6 the first part was added, and that maintained a one to one
mapping between eventfs meta descriptors and the directories and
file inodes and dentries that were dynamically created. The
directories were represented by a eventfs_inode and the files
were represented by a eventfs_file.
In v6.7 the eventfs_file is removed. As all events have the same
directory make up (sched_switch has an "enable", "id", "format",
etc files), the handing of what files are underneath each leaf
eventfs directory is moved back to the tracing subsystem via a
callback. When a event is added to the eventfs, it registers
an array of evenfs_entry's. These hold the names of the files and
the callbacks to call when the file is referenced. The callback gets
the name so that the same callback may be used by multiple files.
The callback then supplies the filesystem_operations structure needed
to create this file.
This has brought the memory footprint of creating multiple eventfs
instances down by 2 megs each!
- User events now has persistent events that are not associated
to a single processes. These are privileged events that hang around
even if no process is attached to them.
- Clean up of seq_buf.
There's talk about using seq_buf more to replace strscpy() and friends.
But this also requires some minor modifications of seq_buf to be
able to do this.
- Expand instance ring buffers individually
Currently if boot up creates an instance, and a trace event is
enabled on that instance, the ring buffer for that instance and the
top level ring buffer are expanded (1.4 MB per CPU). This wastes
memory as this happens when nothing is using the top level instance.
- Other minor clean ups and fixes.

Merge tag 'printk-for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- Another preparation step for introducing printk kthreads. The main
piece is a per-console lock with several features:
- Support three priorities: normal, emergency, and panic. They will
be defined by a context where the lock is taken. A context with a
higher priority is allowed to take over the lock from a context
with a lower one.
The plan is to use the emergency context for Oops and WARN()
messages, and also by watchdogs.
The panic() context will be used on panic CPU.
- The owner might enter/exit regions where it is not safe to take
over the lock. It allows the take over the lock a safe way in the
middle of a message.
For example, serial drivers emit characters one by one. And the
serial port is in a safe state in between.
Only the final console_flush_in_panic() will be allowed to take
over the lock even in the unsafe state (last chance, pray, and
hope).
- A higher priority context might busy wait with a timeout. The
current owner is informed about the waiter and releases the lock
on exit from the unsafe state.
- The new lock is safe even in atomic contexts, including NMI.
Another change is a safe manipulation of per-console sequence number
counter under the new lock.
- simple_strntoull() micro-optimization
- Reduce pr_flush() pooling time.
- Calm down false warning about possible buffer invalid access to
console buffers when CONFIG_PRINTK is disabled.
[ .. and Thomas Gleixner wants to point out that while several of the
commits are attributed to him, he only authored the early versions of
said commits, and that John Ogness and Petr Mladek have been the ones
who sorted out the details and really should be those who get the
credit - Linus ]

there's little I can say which isn't in the individual changelogs.
The lengthier patch series are
- "kdump: use generic functions to simplify crashkernel reservation in
arch", from Baoquan He. This is mainly cleanups and consolidation of
the "crashkernel=" kernel parameter handling.
- After much discussion, David Laight's "minmax: Relax type checks in
min() and max()" is here. Hopefully reduces some typecasting and the
use of min_t() and max_t().
- A group of patches from Oleg Nesterov which clean up and slightly fix
our handling of reads from /proc/PID/task/... and which remove
task_struct.therad_group.

* Generalized infrastructure for 'writable' ID registers, effectively
allowing userspace to opt-out of certain vCPU features for its guest
* Optimization for vSGI injection, opportunistically compressing MPIDR
to vCPU mapping into a table
* Improvements to KVM's PMU emulation, allowing userspace to select
the number of PMCs available to a VM
* Guest support for memory operation instructions (FEAT_MOPS)
* Cleanups to handling feature flags in KVM_ARM_VCPU_INIT, squashing
bugs and getting rid of useless code
* Changes to the way the SMCCC filter is constructed, avoiding wasted
memory allocations when not in use
* Load the stage-2 MMU context at vcpu_load() for VHE systems, reducing
the overhead of errata mitigations
* Miscellaneous kernel and selftest fixes
LoongArch:
* New architecture. The hardware uses the same model as x86, s390
and RISC-V, where guest/host mode is orthogonal to supervisor/user
mode. The virtualization extensions are very similar to MIPS,
therefore the code also has some similarities but it's been cleaned
up to avoid some of the historical bogosities that are found in
arch/mips. The kernel emulates MMU, timer and CSR accesses, while
interrupt controllers are only emulated in userspace, at least for
now.
RISC-V:
* Support for the Smstateen and Zicond extensions
* Support for virtualizing senvcfg
* Support for virtualized SBI debug console (DBCN)
S390:
* Nested page table management can be monitored through tracepoints
and statistics
x86:
* Fix incorrect handling of VMX posted interrupt descriptor in KVM_SET_LAPIC,
which could result in a dropped timer IRQ
* Avoid WARN on systems with Intel IPI virtualization
* Add CONFIG_KVM_MAX_NR_VCPUS, to allow supporting up to 4096 vCPUs without
forcing more common use cases to eat the extra memory overhead.
* Add virtualization support for AMD SRSO mitigation (IBPB_BRTYPE and
SBPB, aka Selective Branch Predictor Barrier).
* Fix a bug where restoring a vCPU snapshot that was taken within 1 second of
creating the original vCPU would cause KVM to try to synchronize the vCPU's
TSC and thus clobber the correct TSC being set by userspace.
* Compute guest wall clock using a single TSC read to avoid generating an
inaccurate time, e.g. if the vCPU is preempted between multiple TSC reads.
* "Virtualize" HWCR.TscFreqSel to make Linux guests happy, which complain
about a "Firmware Bug" if the bit isn't set for select F/M/S combos.
Likewise "virtualize" (ignore) MSR_AMD64_TW_CFG to appease Windows Server
2022.
* Don't apply side effects to Hyper-V's synthetic timer on writes from
userspace to fix an issue where the auto-enable behavior can trigger
spurious interrupts, i.e. do auto-enabling only for guest writes.
* Remove an unnecessary kick of all vCPUs when synchronizing the dirty log
without PML enabled.
* Advertise "support" for non-serializing FS/GS base MSR writes as appropriate.
* Harden the fast page fault path to guard against encountering an invalid
root when walking SPTEs.
* Omit "struct kvm_vcpu_xen" entirely when CONFIG_KVM_XEN=n.
* Use the fast path directly from the timer callback when delivering Xen
timer events, instead of waiting for the next iteration of the run loop.
This was not done so far because previously proposed code had races,
but now care is taken to stop the hrtimer at critical points such as
restarting the timer or saving the timer information for userspace.
* Follow the lead of upstream Xen and ignore the VCPU_SSHOTTMR_future flag.
* Optimize injection of PMU interrupts that are simultaneous with NMIs.
* Usual handful of fixes for typos and other warts.
x86 - MTRR/PAT fixes and optimizations:
* Clean up code that deals with honoring guest MTRRs when the VM has
non-coherent DMA and host MTRRs are ignored, i.e. EPT is enabled.
* Zap EPT entries when non-coherent DMA assignment stops/start to prevent
using stale entries with the wrong memtype.
* Don't ignore guest PAT for CR0.CD=1 && KVM_X86_QUIRK_CD_NW_CLEARED=y.
This was done as a workaround for virtual machine BIOSes that did not
bother to clear CR0.CD (because ancient KVM/QEMU did not bother to
set it, in turn), and there's zero reason to extend the quirk to
also ignore guest PAT.
x86 - SEV fixes:
* Report KVM_EXIT_SHUTDOWN instead of EINVAL if KVM intercepts SHUTDOWN while
running an SEV-ES guest.
* Clean up the recognition of emulation failures on SEV guests, when KVM would
like to "skip" the instruction but it had already been partially emulated.
This makes it possible to drop a hack that second guessed the (insufficient)
information provided by the emulator, and just do the right thing.
Documentation:
* Various updates and fixes, mostly for x86
* MTRR and PAT fixes and optimizations:

Pull kvm updates from Paolo Bonzini:
"ARM:
- Generalized infrastructure for 'writable' ID registers, effectively
allowing userspace to opt-out of certain vCPU features for its
guest
- Optimization for vSGI injection, opportunistically compressing
MPIDR to vCPU mapping into a table
- Improvements to KVM's PMU emulation, allowing userspace to select
the number of PMCs available to a VM
- Guest support for memory operation instructions (FEAT_MOPS)
- Cleanups to handling feature flags in KVM_ARM_VCPU_INIT, squashing
bugs and getting rid of useless code
- Changes to the way the SMCCC filter is constructed, avoiding wasted
memory allocations when not in use
- Load the stage-2 MMU context at vcpu_load() for VHE systems,
reducing the overhead of errata mitigations
- Miscellaneous kernel and selftest fixes
LoongArch:
- New architecture for kvm.
The hardware uses the same model as x86, s390 and RISC-V, where
guest/host mode is orthogonal to supervisor/user mode. The
virtualization extensions are very similar to MIPS, therefore the
code also has some similarities but it's been cleaned up to avoid
some of the historical bogosities that are found in arch/mips. The
kernel emulates MMU, timer and CSR accesses, while interrupt
controllers are only emulated in userspace, at least for now.

Merge tag 'sh-for-v6.7-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux
Pull sh updates from John Paul Adrian Glaubitz:
"While the previously announced patch series for converting arch/sh to
device trees is not yet ready for inclusion to mainline and therefore
didn't make it for this pull request, there are still a small number
changes for v6.7 which include one platform (board plus CPU and driver
code) removal plus two fixes.
The removal sent in by Arnd Bergmann concerns the microdev board which
was an early SuperH prototype board that was never used in production.
With the board removed, we were able to drop the now unused code for
the SH4-202 CPU and well as the driver code for the superhyway bus and
a custom implementation for ioport_map() and ioport_unmap() which will
allow us to simplify ioport handling in the future.
Another patch set by Geert Uytterhoeven revives SuperH BIOS
earlyprintk support which got accidentally disabled in
e76fe57447e88916 ("sh: Remove old early serial console code V2"), the
second patch in the series updates the documentation.
Finally, a patch by Masami Hiramatsu fixes a regression reported by
the kernel test robot which uncovered that arch/sh is not implementing
arch_cmpxchg_local() and therefore needs use __generic_cmpxchg_local()
instead"
