failed ->ki_pos value is unreliable in such cases. For an obvious example, consider O_DSYNC write - we feed the data to page cache and start IO, then we make sure it's completed. Update of ->ki_pos is dealt with by the first part; failure in the second ends up with negative value returned _and_ ->ki_pos left advanced as if sync had been successful. In the same situation write(2) does not advance the file position at all.

2023-10-27x86/tsc: Defer marking TSC unstable to a workerThomas Gleixner

In case that the synchronization with the upcoming CPU fails, the TSC has to be marked unstable via clocksource_mark_unstable(). clocksource_mark_unstable() acquires 'watchdog_lock', but that lock is taken with interrupts enabled in the watchdog timer callback to minimize interrupt disabled time. That's obviously a possible deadlock scenario, Before that change the synchronization function was invoked in thread context so this could not happen. As it is not crucical whether the unstable marking happens slightly delayed, defer the call to a worker thread which avoids the lock context problem.

2023-10-27x86/i8259: Skip probing when ACPI/MADT advertises PCAT compatibilityThomas Gleixner
David and a few others reported that on certain newer systems some legacy interrupts fail to work correctly. Debugging revealed that the BIOS of these systems leaves the legacy PIC in uninitialized state which makes the PIC detection fail and the kernel switches to a dummy implementation. Unfortunately this fallback causes quite some code to fail as it depends on checks for the number of legacy PIC interrupts or the availability of the real PIC. In theory there is no reason to use the PIC on any modern system when IO/APIC is available, but the dependencies on the related checks cannot be resolved trivially and on short notice. This needs lots of analysis and rework. The PIC detection has been added to avoid quirky checks and force selection of the dummy implementation all over the place, especially in VM guest scenarios. So it's not an option to revert the relevant commit as that would break a lot of other scenarios. One solution would be to try to initialize the PIC on detection fail and retry the detection, but that puts the burden on everything which does not have a PIC. Fortunately the ACPI/MADT table header has a flag field, which advertises in bit 0 that the system is PCAT compatible, which means it has a legacy 8259 PIC. Evaluate that bit and if set avoid the detection routine and keep the real PIC installed, which then gets initialized (for nothing) and makes the rest of the code with all the dependencies work again.

2023-10-27platform/x86: Add s2idle quirk for more Lenovo laptopsDavid Lazar
When suspending to idle and resuming on some Lenovo laptops using the Mendocino APU, multiple NVME IOMMU page faults occur, showing up in dmesg as repeated errors: nvme 0000:01:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000b address=0xb6674000 flags=0x0000] The system is unstable afterwards. Applying the s2idle quirk introduced by commit 455cd867b85b ("platform/x86: thinkpad_acpi: Add a s2idle resume quirk for a number of laptops") allows these systems to work with the IOMMU enabled and s2idle resume to work.

2023-10-27futex: Don't include process MM in futex key on no-MMUBen Wolsieffer
On no-MMU, all futexes are treated as private because there is no need to map a virtual address to physical to match the futex across processes. This doesn't quite work though, because private futexes include the current process's mm_struct as part of their key. This makes it impossible for one process to wake up a shared futex being waited on in another process. Fix this bug by excluding the mm_struct from the key. With a single address space, the futex address is already a unique key.

2023-10-27scsi: sd: Introduce manage_shutdown device flagDamien Le Moal
Commit aa3998dbeb3a ("ata: libata-scsi: Disable scsi device manage_system_start_stop") change setting the manage_system_start_stop flag to false for libata managed disks to enable libata internal management of disk suspend/resume. However, a side effect of this change is that on system shutdown, disks are no longer being stopped (set to standby mode with the heads unloaded). While this is not a critical issue, this unclean shutdown is not recommended and shows up with increased smart counters (e.g. the unexpected power loss counter "Unexpect_Power_Loss_Ct"). Instead of defining a shutdown driver method for all ATA adapter drivers (not all of them define that operation), this patch resolves this issue by further refining the sd driver start/stop control of disks using the new flag manage_shutdown. If this new flag is set to true by a low level driver, the function sd_shutdown() will issue a START STOP UNIT command with the start argument set to 0 when a disk needs to be powered off (suspended) on system power off, that is, when system_state is equal to SYSTEM_POWER_OFF. Similarly to the other manage_xxx flags, the new manage_shutdown flag is exposed through sysfs as a read-write device attribute. To avoid any confusion between manage_shutdown and manage_system_start_stop, the comments describing these flags in include/scsi/scsi.h are also improved.
