2025-04-28ACPICA: Drop stale comment about the header file contentSudeep Holla
ACPICA commit 48e7c4cd893270dab8d05e6d75fbf23d0fcbb267 Commit a025731aec31 ("Restructure ACPI table files") restructed the header files and moved lots of tables that are in the ACPI specification to actbl2.h(e.g.: APIC/MADT, PCCT, PPTT, ..etc). This restructure made the comment stating this header file contains tables that are not in the ACPI specification incorrect. From that commit onwards it has remained as stale. Let us get rid of it as it might be misleading.

2025-04-28cpufreq: Fix setting policy limits when frequency tables are usedRafael J. Wysocki
Commit 7491cdf46b5c ("cpufreq: Avoid using inconsistent policy->min and policy->max") overlooked the fact that policy->min and policy->max were accessed directly in cpufreq_frequency_table_target() and in the functions called by it. Consequently, the changes made by that commit led to problems with setting policy limits. Address this by passing the target frequency limits to __resolve_freq() and cpufreq_frequency_table_target() and propagating them to the functions called by the latter.

2025-04-28iommu: Handle yet another race around registrationRobin Murphy
Next up on our list of race windows to close is another one during iommu_device_register() - it's now OK again for multiple instances to run their bus_iommu_probe() in parallel, but an iommu_probe_device() can still also race against a running bus_iommu_probe(). As Johan has managed to prove, this has now become a lot more visible on DT platforms wth driver_async_probe where a client driver is attempting to probe in parallel with its IOMMU driver - although commit b46064a18810 ("iommu: Handle race with default domain setup") resolves this from the client driver's point of view, this isn't before of_iommu_configure() has had the chance to attempt to "replay" a probe that the bus walk hasn't even tried yet, and so still cause the out-of-order group allocation behaviour that we're trying to clean up (and now warning about). The most reliable thing to do here is to explicitly keep track of the "iommu_device_register() is still running" state, so we can then special-case the ops lookup for the replay path (based on dev->iommu again) to let that think it's still waiting for the IOMMU driver to appear at all. This still leaves the longstanding theoretical case of iommu_bus_notifier() being triggered during bus_iommu_probe(), but it's not so simple to defer a notifier, and nobody's ever reported that being a visible issue, so let's quietly kick that can down the road for now...

2025-04-28timekeeping: Prevent coarse clocks going backwardsThomas Gleixner
Lei Chen raised an issue with CLOCK_MONOTONIC_COARSE seeing time inconsistencies. Lei tracked down that this was being caused by the adjustment: tk->tkr_mono.xtime_nsec -= offset; which is made to compensate for the unaccumulated cycles in offset when the multiplicator is adjusted forward, so that the non-_COARSE clockids don't see inconsistencies. However, the _COARSE clockid getter functions use the adjusted xtime_nsec value directly and do not compensate the negative offset via the clocksource delta multiplied with the new multiplicator. In that case the caller can observe time going backwards in consecutive calls. By design, this negative adjustment should be fine, because the logic run from timekeeping_adjust() is done after it accumulated approximately multiplicator * interval_cycles into xtime_nsec. The accumulated value is always larger then the mult_adj * offset value, which is subtracted from xtime_nsec. Both operations are done together under the tk_core.lock, so the net change to xtime_nsec is always always be positive. However, do_adjtimex() calls into timekeeping_advance() as well, to apply the NTP frequency adjustment immediately. In this case, timekeeping_advance() does not return early when the offset is smaller then interval_cycles. In that case there is no time accumulated into xtime_nsec. But the subsequent call into timekeeping_adjust(), which modifies the multiplicator, subtracts from xtime_nsec to correct for the new multiplicator. Here because there was no accumulation, xtime_nsec becomes smaller than before, which opens a window up to the next accumulation, where the _COARSE clockid getters, which don't compensate for the offset, can observe the inconsistency. This has been tried to be fixed by forwarding the timekeeper in the case that adjtimex() adjusts the multiplier, which resets the offset to zero: 757b000f7b93 ("timekeeping: Fix possible inconsistencies in _COARSE clockids") That works correctly, but unfortunately causes a regression on the adjtimex() side. There are two issues: 1) The forwarding of the base time moves the update out of the original period and establishes a new one. 2) The clearing of the accumulated NTP error is changing the behaviour as well. User-space expects that multiplier/frequency updates are in effect, when the syscall returns, so delaying the update to the next tick is not solving the problem either. Commit 757b000f7b93 was reverted so that the established expectations of user space implementations (ntpd, chronyd) are restored, but that obviously brought the inconsistencies back. One of the initial approaches to fix this was to establish a separate storage for the coarse time getter nanoseconds part by calculating it from the offset. That was dropped on the floor because not having yet another state to maintain was simpler. But given the result of the above exercise, this solution turns out to be the right one. Bring it back in a slightly modified form. Thus introduce timekeeper::coarse_nsec and store that nanoseconds part in it, switch the time getter functions and the VDSO update to use that value. coarse_nsec is set on operations which forward or initialize the timekeeper and after time was accumulated during a tick. If there is no accumulation the timestamp is unchanged. This leaves the adjtimex() behaviour unmodified and prevents coarse time from going backwards.

2025-04-26vt: properly support zero-width Unicode code pointsNicolas Pitre
Zero-width Unicode code points are causing misalignment in vertically aligned content, disrupting the visual layout. Let's handle zero-width code points more intelligently. Double-width code points are stored in the screen grid followed by a white space code point to create the expected screen layout. When a double-width code point is followed by a zero-width code point in the console incoming bytestream (e.g., an emoji with a presentation selector) then we may replace the white space padding by that zero-width code point instead of dropping it. This maximize screen content information while preserving proper layout. If a zero-width code point is preceded by a single-width code point then the above trick is not possible and such zero-width code point must be dropped. VS16 (Variation Selector 16, U+FE0F) is special as it typically doubles the width of the preceding single-width code point. We handle that case by giving VS16 a width of 1 instead of 0 when that happens.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs fixes from Christian Brauner: - For some reason we went from zero to three maintainers for HFS/HFS+ in a matter of days. The lesson to learn from this might just be that we need to threaten code removal more often!? - Fix a regression introduced by enabling large folios for lage logical block sizes. This has caused issues for noref migration with large folios due to sleeping while in an atomic context. New sleeping variants of pagecache lookup helpers are introduced. These helpers take the folio lock instead of the mapping's private spinlock. The problematic users are converted to the sleeping variants and serialize against noref migration. Atomic users will bail on seeing the new BH_Migrate flag. This also shrinks the critical region of the mapping's private lock and the new blocking callers reduce contention on the spinlock for bdev mappings. - Fix two bugs in do_move_mount() when with MOVE_MOUNT_BENEATH. The first bug is using a mountpoint that is located on a mount we're not holding a reference to. The second bug is putting the mountpoint after we've called namespace_unlock() as it's no longer guaranteed that it does stay a mountpoint. - Remove a pointless call to vfs_getattr_nosec() in the devtmpfs code just to query i_mode instead of simply querying the inode directly. This also avoids lifetime issues for the dm code by an earlier bugfix this cycle that moved bdev_statx() handling into vfs_getattr_nosec(). - Fix AT_FDCWD handling with getname_maybe_null() in the xattr code. - Fix a performance regression for files when multiple callers issue a close when it's not the last reference. - Remove a duplicate noinline annotation from pipe_clear_nowait(). * tag 'vfs-6.15-rc4.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: fs/xattr: Fix handling of AT_FDCWD in setxattrat(2) and getxattrat(2) MAINTAINERS: hfs/hfsplus: add myself as maintainer splice: remove duplicate noinline from pipe_clear_nowait devtmpfs: don't use vfs_getattr_nosec to query i_mode fix a couple of races in MNT_TREE_BENEATH handling by do_move_mount() fs: fall back to file_ref_put() for non-last reference mm/migrate: fix sleep in atomic for large folios and buffer heads fs/ext4: use sleeping version of sb_find_get_block() fs/jbd2: use sleeping version of __find_get_block() fs/ocfs2: use sleeping version of __find_get_block() fs/buffer: use sleeping version of __find_get_block() fs/buffer: introduce sleeping flavors for pagecache lookups MAINTAINERS: add HFS/HFS+ maintainers fs/buffer: split locking for pagecache lookups

2025-04-25Bluetooth: hci_conn: Fix not setting timeout for BIG Create SyncLuiz Augusto von Dentz
BIG Create Sync requires the command to just generates a status so this makes use of __hci_cmd_sync_status_sk to wait for HCI_EVT_LE_BIG_SYNC_ESTABLISHED, also because of this chance it is not longer necessary to use a custom method to serialize the process of creating the BIG sync since the cmd_work_sync itself ensures only one command would be pending which now awaits for HCI_EVT_LE_BIG_SYNC_ESTABLISHED before proceeding to next connection.

2025-04-25ASoC: codec: tpa6130a2: Convert to GPIO descriptorsMark Brown
Merge series from "Peng Fan (OSS)" <peng.fan@oss.nxp.com>: Per Mark's comments in [1], each driver in one patchset and not merge the changes to one driver in one patch, so worked out three patches. - Sort the included headers. - Drop sound/tpa6130a2-plat.h because no user is creating the device using platform data - Covert to GPIO descriptors Checking the DTS polarity, all users are using GPIOD_ACTIVE_HIGH. so all should work as expected with this patch. I not have hardware to test, just my best effort to do this. [1] https://lore.kernel.org/all/66db9962-d773-4c7a-bf59-4698eca9eedc@sirena.org.uk/

2025-04-25comedi: remove the mapping of the Comedi buffer in vmalloc address spaceIan Abbott
Now that all the code that accesses the Comedi buffer data does so page-by-page, using the `virt_addr` member of `struct comedi_buf_page` to point to the data of each page, do not linearly map the buffer into vmalloc address space (pointed to by the `prealloc_buf` member of `struct comedi_async`). That was only done for convenience, but was not done for those drivers that need a DMA coherent buffer, which is allocated in a single chunk. Remove the `prealloc_buf` member as it is no longer used.
