2025-03-20rust: str: implement `Index` for `BStr`Andreas Hindborg
The `Index` implementation on `BStr` was lost when we switched `BStr` from a type alias of `[u8]` to a newtype. Add back `Index` by implementing `Index` for `BStr` when `Index` would be implemented for `[u8]`.

2025-03-20Merge branch 'kvm-nvmx-and-vm-teardown' into HEADPaolo Bonzini
The immediate issue being fixed here is a nVMX bug where KVM fails to detect that, after nested VM-Exit, L1 has a pending IRQ (or NMI). However, checking for a pending interrupt accesses the legacy PIC, and x86's kvm_arch_destroy_vm() currently frees the PIC before destroying vCPUs, i.e. checking for IRQs during the forced nested VM-Exit results in a NULL pointer deref; that's a prerequisite for the nVMX fix. The remaining patches attempt to bring a bit of sanity to x86's VM teardown code, which has accumulated a lot of cruft over the years. E.g. KVM currently unloads each vCPU's MMUs in a separate operation from destroying vCPUs, all because when guest SMP support was added, KVM had a kludgy MMU teardown flow that broke when a VM had more than one 1 vCPU. And that oddity lived on, for 18 years... Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Now that the rstat lock is being re-acquired on every CPU iteration in cgroup_rstat_flush_locked(), having the initially acquire the lock is unnecessary and unclear. Inline cgroup_rstat_flush_locked() into cgroup_rstat_flush() and move the lock/unlock calls to the beginning and ending of the loop body to make the critical section obvious. cgroup_rstat_flush_hold/release() do not make much sense with the lock being dropped and reacquired internally. Since it has no external callers, remove it and explicitly acquire the lock in cgroup_base_stat_cputime_show() instead. This leaves the code with a single flushing function, cgroup_rstat_flush().

2025-03-20drm/i915/watermark: Check bounds for scaler_users for dsc prefill latencyAnkit Nautiyal
Currently, during the computation of global watermarks, the latency for each scaler user is calculated to compute the DSC prefill latency. At this point, the number of scaler users can exceed the number of supported scalers, which is checked later in intel_atomic_setup_scalers(). This can cause issues when the number of scaler users exceeds the number of supported scalers. While checking for DSC prefill, ensure that the number of scaler users does not exceed the number of supported scalers.

2025-03-20ASoC: wm8904: Add DMIC and DRC supportMark Brown
Merge series from Francesco Dolcini <francesco@dolcini.it>: This patch series adds DMIC and DRC support to the WM8904 driver, a new of_ helper is added to simplify the driver code. DRC functionality is added in the same patch series to provide the necessary dynamic range control to make DMIC support useful. The WM8904 supports digital microphones on two of its inputs: IN1L/DMICDAT1 and IN1R/DMICDAT2. These two inputs can either be connected to an ADC or to the DMIC system. There is an ADC for each line, and only one DMIC block. This DMIC block is either connected to DMICDAT1 or to DMICDAT2. One DMIC data line supports two digital microphones via time multiplexing. The pin's functionality is decided during hardware design (IN1L vs DMICDAT1 and IN1R vs DMICDAT2). This is reflected in the Device Tree. If one line is analog and one is DMIC, we need to be able to switch between ADC and DMIC at runtime. The DMIC source is known from the Device Tree. If both are DMIC inputs, we need to be able to switch the DMIC source. There is no need to switch between ADC and DMIC at runtime. Therefore, kcontrols are dynamically added by the driver depending on its Device Tree configuration. This is a heavy rework of a previous patch series provided by Alifer Moraes and Pierluigi Passaro, https://lore.kernel.org/lkml/20220307141041.27538-1-alifer.m@variscite.com.
2025-03-20Tidy up ASoC control get and put handlersMark Brown
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: There is a lot of duplicated and occasionally slightly incorrect code around the ASoC control get and put handlers. This series add some kunit tests and then refactors the code to get all the tests passing and reduce some of the duplication. The focus here is on the volsw handlers, future work could still be done on some of the others but these were the ones that most required attention. Hopefully the only slightly controversal change is the very last patch which changes platform_max to be applied after the control type is determined, more discussion in the commit message for that one.

2025-03-20serial: sh-sci: Save and restore more registersGeert Uytterhoeven
On (H)SCIF with a Baud Rate Generator for External Clock (BRG), there are multiple ways to configure the requested serial speed. If firmware uses a different method than Linux, and if any debug info is printed after the Bit Rate Register (SCBRR) is restored, but before termios is reconfigured (which configures the alternative method), the system may lock-up during resume. Fix this by saving and restoring the contents of the BRG Frequency Division (SCDL) and Clock Select (SCCKS) registers as well. Also save and restore the HSCIF's Sampling Rate Register (HSSRR), which configures the sampling point, and the SCIFA/SCIFB's Serial Port Control and Data Registers (SCPCR/SCPDR), which configure the optional control flow signals. After this, all registers that are not saved/restored are either: - read-only, - write-only, - status registers containing flags with clear-after-set semantics, - FIFO Data Count Trigger registers, which do not matter much for the serial console.
