Fix a potential race in gmap_make_secure() and remove the last user of follow_page() without FOLL_GET. The old code is locking something it doesn't have a reference to, and as explained by Jason and David in this discussion: https://lore.kernel.org/linux-mm/Y9J4P%2FRNvY1Ztn0Q@nvidia.com/ it can lead to all kind of bad things, including the page getting unmapped (MADV_DONTNEED), freed, reallocated as a larger folio and the unlock_page() would target the wrong bit. There is also another race with the FOLL_WRITE, which could race between the follow_page() and the get_locked_pte(). The main point is to remove the last use of follow_page() without FOLL_GET or FOLL_PIN, removing the races can be considered a nice bonus.

On machines without the Destroy Secure Configuration Fast UVC, the topmost level of page tables is set aside and freed asynchronously as last step of the asynchronous teardown. Each gmap has a host_to_guest radix tree mapping host (userspace) addresses (with 1M granularity) to gmap segment table entries (pmds). If a guest is smaller than 2GB, the topmost level of page tables is the segment table (i.e. there are only 2 levels). Replacing it means that the pointers in the host_to_guest mapping would become stale and cause all kinds of nasty issues. This patch fixes the issue by disallowing asynchronous teardown for guests with only 2 levels of page tables. Userspace should (and already does) try using the normal destroy if the asynchronous one fails. Update s390_replace_asce so it refuses to replace segment type ASCEs. This is still needed in case the normal destroy VM fails.

When the kvm module is unloaded, zpci_setup_aipb() perists some data in the zpci_aipb structure in s390 pci code. Note that this struct is also passed to firmware in the zpci_set_irq_ctrl() call and thus the GAIT must be a physical address. On module re-insertion, the GAIT is restored from this structure in zpci_reset_aipb(). But it is a physical address, hence this may cause issues when the kvm module is unloaded and loaded again. Fix virtual vs physical address confusion (which currently are the same) by adding the necessary physical-to-virtual-conversion in zpci_reset_aipb().

The APCB is part of the CRYCB. The calculation of the APCB origin can be done by adding the APCB offset to the CRYCB origin. Current code makes confusing transformations, converting the CRYCB origin to a pointer to calculate the APCB origin. Let's make things simpler and keep the CRYCB origin to make these calculations.

AMD has issued an advisory indicating that having fTPM enabled in BIOS can cause "stuttering" in the OS. This issue has been fixed in newer versions of the fTPM firmware, but it's up to system designers to decide whether to distribute it. This issue has existed for a while, but is more prevalent starting with kernel 6.1 because commit b006c439 ("hwrng: core - start hwrng kthread also for untrusted sources") started to use the fTPM for hwrng by default. However, all uses of /dev/hwrng result in unacceptable stuttering. So, simply disable registration of the defective hwrng when detecting these faulty fTPM versions. As this is caused by faulty firmware, it is plausible that such a problem could also be reproduced by other TPM interactions, but this hasn't been shown by any user's testing or reports. It is hypothesized to be triggered more frequently by the use of the RNG because userspace software will fetch random numbers regularly. Intentionally continue to register other TPM functionality so that users that rely upon PCR measurements or any storage of data will still have access to it. If it's found later that another TPM functionality is exacerbating this problem a module parameter it can be turned off entirely and a module parameter can be introduced to allow users who rely upon fTPM functionality to turn it on even though this problem is present.

tpm_read_log_acpi() should return -ENODEV when no eventlog from the ACPI table is found. If the firmware vendor includes an invalid log address we are unable to map from the ACPI memory and tpm_read_log() returns -EIO which would abort discovery of the eventlog. Change the return value from -EIO to -ENODEV when acpi_os_map_iomem() fails to map the event log.

Pull clone3 fix from Christian Brauner: "A simple fix for the clone3() system call. The CLONE_NEWTIME allows the creation of time namespaces. The flag reuses a bit from the CSIGNAL bits that are used in the legacy clone() system call to set the signal that gets sent to the parent after the child exits. The clone3() system call doesn't rely on CSIGNAL anymore as it uses a dedicated .exit_signal field in struct clone_args. So we blocked all CSIGNAL bits in clone3_args_valid(). When CLONE_NEWTIME was introduced and reused a CSIGNAL bit we forgot to adapt clone3_args_valid() causing CLONE_NEWTIME with clone3() to be rejected.

The cpumask_check() was unnecessarily tight, and causes problems for the users of cpumask_next(). We have a number of users that take the previous return value of one of the bit scanning functions and subtract one to keep it in "range". But since the scanning functions end up returning up to 'small_cpumask_bits' instead of the tighter 'nr_cpumask_bits', the range really needs to be using that widened form. [ This "previous-1" behavior is also the reason we have all those comments about /* -1 is a legal arg here. */ and separate checks for that being ok. So we could have just made "small_cpumask_bits-1" be a similar special "don't check this" value. Tetsuo Handa even suggested a patch that only does that for cpumask_next(), since that seems to be the only actual case that triggers, but that all makes it even _more_ magical and special. So just relax the check ] One example of this kind of pattern being the 'c_start()' function in arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on other architectures.

The only caller of ext4_find_inline_data_nolock() that needs setting of EXT4_STATE_MAY_INLINE_DATA flag is ext4_iget_extra_inode(). In ext4_write_inline_data_end() we just need to update inode->i_inline_off. Since we are going to add one more caller that does not need to set EXT4_STATE_MAY_INLINE_DATA, just move setting of EXT4_STATE_MAY_INLINE_DATA out to ext4_iget_extra_inode().

Pull io_uring fixes from Jens Axboe: - Stop setting PF_NO_SETAFFINITY on io-wq workers. This has been reported in the past as it confuses some applications, as some of their threads will fail with -1/EINVAL if attempted affinitized. Most recent report was on cpusets, where enabling that with io-wq workers active will fail. Just deal with the mask changing by checking when a worker times out, and then exit if we have no work pending. - Fix an issue with passthrough support where we don't properly check if the file type has pollable uring_cmd support. - Fix a reported W=1 warning on a variable being set and unused.
