2023-06-26thermal: Allow selecting the bang-bang governor as defaultThierry Reding
For many setups the bang-bang governor is exactly what we want. Many ARM SoC-based devices use fans to cool down the entire SoC and that works well only with the bang-bang governor because it uses the hysteresis in order to let the fan run for a while to cool the SoC down below the trip point before switching it off again. The step-wise governor will behave strangely in these situations. It doesn't use the hysteresis, so it can lead to situations where the fan is turned on for only a very brief period and then is switched back off, only to get switched back on again very quickly because the SoC hasn't cooled down very much.

2023-06-23workqueue: clean up WORK_* constant types, clarify maskingLinus Torvalds
Dave Airlie reports that gcc-13.1.1 has started complaining about some of the workqueue code in 32-bit arm builds: kernel/workqueue.c: In function ‘get_work_pwq’: kernel/workqueue.c:713:24: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 713 | return (void *)(data & WORK_STRUCT_WQ_DATA_MASK); | ^ [ ... a couple of other cases ... ] and while it's not immediately clear exactly why gcc started complaining about it now, I suspect it's some C23-induced enum type handlign fixup in gcc-13 is the cause. Whatever the reason for starting to complain, the code and data types are indeed disgusting enough that the complaint is warranted. The wq code ends up creating various "helper constants" (like that WORK_STRUCT_WQ_DATA_MASK) using an enum type, which is all kinds of confused. The mask needs to be 'unsigned long', not some unspecified enum type. To make matters worse, the actual "mask and cast to a pointer" is repeated a couple of times, and the cast isn't even always done to the right pointer, but - as the error case above - to a 'void *' with then the compiler finishing the job. That's now how we roll in the kernel. So create the masks using the proper types rather than some ambiguous enumeration, and use a nice helper that actually does the type conversion in one well-defined place. Incidentally, this magically makes clang generate better code. That, admittedly, is really just a sign of clang having been seriously confused before, and cleaning up the typing unconfuses the compiler too.

2023-06-23kselftest/arm64: Add a test case for TPIDR2 restoreMark Brown
Due to the fact that TPIDR2 is intended to be managed by libc we don't currently test modifying it via the signal context since that might disrupt libc's usage of it and cause instability. We can however test the opposite case with less risk, modifying TPIDR2 in a signal handler and making sure that the original value is restored after returning from the signal handler. Add a test which does this.

2023-06-23arm64/signal: Restore TPIDR2 register rather than memory stateMark Brown
Currently when restoring the TPIDR2 signal context we set the new value from the signal frame in the thread data structure but not the register, following the pattern for the rest of the data we are restoring. This does not work in the case of TPIDR2, the register always has the value for the current task. This means that either we return to userspace and ignore the new value or we context switch and save the register value on top of the newly restored value. Load the value from the signal context into the register instead.

2023-06-23scsi/sg: don't grab scsi host module referenceYu Kuai
In order to prevent request_queue to be freed before cleaning up blktrace debugfs entries, commit db59133e9279 ("scsi: sg: fix blktrace debugfs entries leakage") use scsi_device_get(), however, scsi_device_get() will also grab scsi module reference and scsi module can't be removed. It's reported that blktests can't unload scsi_debug after block/001: blktests (master) # ./check block block/001 (stress device hotplugging) [failed] +++ /root/blktests/results/nodev/block/001.out.bad 2023-06-19 Running block/001 Stressing sd +modprobe: FATAL: Module scsi_debug is in use.

2023-06-23io_uring: remove io_free_req_twPavel Begunkov
Request completion is a very hot path in general, but there are 3 places that can be doing it: io_free_batch_list(), io_req_complete_post() and io_free_req_tw(). io_free_req_tw() is used rather marginally and we don't care about it. Killing it can help to clean up and optimise the left two, do that by replacing it with io_req_task_complete(). There are two things to consider: 1) io_free_req() is called when all refs are put, so we need to reinit references. The easiest way to do that is to clear REQ_F_REFCOUNT. 2) We also don't need a cqe from it, so silence it with REQ_F_CQE_SKIP.

2023-06-23clocksource/drivers/hyper-v: Rework clocksource and sched clock setupMichael Kelley
Current code assigns either the Hyper-V TSC page or MSR-based ref counter as the sched clock. This may be sub-optimal in two cases. First, if there is hardware support to ensure consistent TSC frequency across live migrations and Hyper-V is using that support, the raw TSC is a faster source of time than the Hyper-V TSC page. Second, the MSR-based ref counter is relatively slow because reads require a trap to the hypervisor. As such, it should never be used as the sched clock. The native sched clock based on the raw TSC or jiffies is much better. Rework the sched clock setup so it is set to the TSC page only if Hyper-V indicates that the TSC may have inconsistent frequency across live migrations. Also, remove the code that sets the sched clock to the MSR-based ref counter. In the cases where it is not set, the sched clock will then be the native sched clock. As part of the rework, always enable both the TSC page clocksource and the MSR-based ref counter clocksource. Set the ratings so the TSC page clocksource is preferred. While the MSR-based ref counter clocksource is unlikely to ever be the default, having it available for manual selection is convenient for development purposes.
