2025-04-07pwm: stm32: Search an appropriate duty_cycle if period cannot be modifiedUwe Kleine-König
If another channel is already enabled period must not be modified. If the requested period is smaller than this unchangable period the driver is still supposed to search a duty_cycle according to the usual rounding rules. So don't set the duty_cycle to 0 but continue to determine an appropriate value for ccr.

2025-04-07pwm: Let pwm_set_waveform() succeed even if lowlevel driver rounded upUwe Kleine-König
Waveform parameters are supposed to be rounded down to the next value possible for the hardware. However when a requested value is too small, .round_waveform_tohw() is supposed to pick the next bigger value and return 1. Let pwm_set_waveform() behave in the same way. This creates consistency between pwm_set_waveform_might_sleep() with exact=false and pwm_round_waveform_might_sleep() + pwm_set_waveform_might_sleep() with exact=true. The PWM_DEBUG rounding check has to be adapted to only trigger if no uprounding happend.

2025-04-07platform/x86: intel_pmc_ipc: add option to build without ACPIDavid E. Box
Introduce a configuration option that allows users to build the intel_pmc_ipc driver without ACPI support. This is useful for systems where ACPI is not available or desired. Based on the discussion from the patch [1], it was necessary to provide this option to accommodate specific use cases.

2025-04-07x86/xen: fix balloon target initialization for PVH dom0Roger Pau Monne
PVH dom0 re-uses logic from PV dom0, in which RAM ranges not assigned to dom0 are re-used as scratch memory to map foreign and grant pages. Such logic relies on reporting those unpopulated ranges as RAM to Linux, and mark them as reserved. This way Linux creates the underlying page structures required for metadata management. Such approach works fine on PV because the initial balloon target is calculated using specific Xen data, that doesn't take into account the memory type changes described above. However on HVM and PVH the initial balloon target is calculated using get_num_physpages(), and that function does take into account the unpopulated RAM regions used as scratch space for remote domain mappings. This leads to PVH dom0 having an incorrect initial balloon target, which causes malfunction (excessive memory freeing) of the balloon driver if the dom0 memory target is later adjusted from the toolstack. Fix this by using xen_released_pages to account for any pages that are part of the memory map, but are already unpopulated when the balloon driver is initialized. This accounts for any regions used for scratch remote mappings. Note on x86 xen_released_pages definition is moved to enlighten.c so it's uniformly available for all Xen-enabled builds. Take the opportunity to unify PV with PVH/HVM guests regarding the usage of get_num_physpages(), as that avoids having to add different logic for PV vs PVH in both balloon_add_regions() and arch_xen_unpopulated_init(). Much like a6aa4eb994ee, the code in this changeset should have been part of 38620fc4e893.

the server Fix regression in mounts to e.g. onedrive shares. Generally, reparse points are processed by the SMB server during the SMB OPEN request, but there are few reparse points which do not have OPEN-like meaning for the SMB server and has to be processed by the SMB client. Those are symlinks and special files (fifo, socket, block, char). For Linux SMB client, it is required to process also name surrogate reparse points as they represent another entity on the SMB server system. Linux client will mark them as separate mount points. Examples of name surrogate reparse points are NTFS junction points (e.g. created by the "mklink" tool on Windows servers). So after processing the name surrogate reparse points, clear the -EOPNOTSUPP error code returned from the parse_reparse_point() to let SMB server to process reparse points. And remove printing misleading error message "unhandled reparse tag:" as reparse points are handled by SMB server and hence unhandled fact is normal operation.

Existing code only configures one of WSA_MACRO_TX0 or WSA_MACRO_TX1 paths eventhough we enable both of them. Fix this bug by adding proper checks and rearranging some of the common code to able to allow setting both TX0 and TX1 paths Without this patch only one channel gets enabled in VI path instead of 2 channels.

2025-04-06perf/core: Fix WARN_ON(!ctx) in __free_event() for partial initGabriel Shahrouzi
Move the get_ctx(child_ctx) call and the child_event->ctx assignment to occur immediately after the child event is allocated. Ensure that child_event->ctx is non-NULL before any subsequent error path within inherit_event calls free_event(), satisfying the assumptions of the cleanup code. Details: There's no clear Fixes tag, because this bug is a side-effect of multiple interacting commits over time (up to 15 years old), not a single regression. The code initially incremented refcount then assigned context immediately after the child_event was created. Later, an early validity check for child_event was added before the refcount/assignment. Even later, a WARN_ON_ONCE() cleanup check was added, assuming event->ctx is valid if the pmu_ctx is valid. The problem is that the WARN_ON_ONCE() could trigger after the initial check passed but before child_event->ctx was assigned, violating its precondition. The solution is to assign child_event->ctx right after its initial validation. This ensures the context exists for any subsequent checks or cleanup routines, resolving the WARN_ON_ONCE(). To resolve it, defer the refcount update and child_event->ctx assignment directly after child_event->pmu_ctx is set but before checking if the parent event is orphaned. The cleanup routine depends on event->pmu_ctx being non-NULL before it verifies event->ctx is non-NULL. This also maintains the author's original intent of passing in child_ctx to find_get_pmu_context before its refcount/assignment.
