2026-04-05mm: zswap: add per-memcg stat for incompressible pagesJiayuan Chen
Patch series "mm: zswap: add per-memcg stat for incompressible pages", v3. In containerized environments, knowing which cgroup is contributing incompressible pages to zswap is essential for effective resource management. This series adds a new per-memcg stat 'zswap_incomp' to track incompressible pages, along with a selftest. This patch (of 2): The global zswap_stored_incompressible_pages counter was added in commit dca4437a5861 ("mm/zswap: store <PAGE_SIZE compression failed page as-is") to track how many pages are stored in raw (uncompressed) form in zswap. However, in containerized environments, knowing which cgroup is contributing incompressible pages is essential for effective resource management [1]. Add a new memcg stat 'zswap_incomp' to track incompressible pages per cgroup. This helps administrators and orchestrators to: 1. Identify workloads that produce incompressible data (e.g., encrypted data, already-compressed media, random data) and may not benefit from zswap. 2. Make informed decisions about workload placement - moving incompressible workloads to nodes with larger swap backing devices rather than relying on zswap. 3. Debug zswap efficiency issues at the cgroup level without needing to correlate global stats with individual cgroups. While the compression ratio can be estimated from existing stats (zswap / zswapped * PAGE_SIZE), this doesn't distinguish between "uniformly poor compression" and "a few completely incompressible pages mixed with highly compressible ones". The zswap_incomp stat provides direct visibility into the latter case.

reproducible-builds.rst The debug information part of the "Absolute filenames" section in the reproducible builds document only mentions providing '-fdebug-prefix-map' to KCFLAGS but it needs to be provided to KAFLAGS as well since debug information has been generated for assembly files for a long time. Additionally, mention that the build directory may also appear as an absolute path in the debug information (via DW_AT_comp_dir), so it needs to be overridden via '-fdebug-prefix-map' as well.

2026-04-04prctl: cfi: change the branch landing pad prctl()s to be more descriptivePaul Walmsley
Per Linus' comments requesting the replacement of "INDIR_BR_LP" in the indirect branch tracking prctl()s with something more readable, and suggesting the use of the speculation control prctl()s as an exemplar, reimplement the prctl()s and related constants that control per-task forward-edge control flow integrity. This primarily involves two changes. First, the prctls are restructured to resemble the style of the speculative execution workaround control prctls PR_{GET,SET}_SPECULATION_CTRL, to make them easier to extend in the future. Second, the "indir_br_lp" abbrevation is expanded to "branch_landing_pads" to be less telegraphic. The kselftest and documentation is adjusted accordingly.

2026-04-03dt-bindings: net: Fix Tegra234 MGBE PTP clockJon Hunter
The PTP clock for the Tegra234 MGBE device is incorrectly named 'ptp-ref' and should be 'ptp_ref'. This is causing the following warning to be observed on Tegra234 platforms that use this device: ERR KERN tegra-mgbe 6800000.ethernet eth0: Invalid PTP clock rate WARNING KERN tegra-mgbe 6800000.ethernet eth0: PTP init failed Although this constitutes an ABI breakage in the binding for this device, PTP support has clearly never worked and so fix this now so we can correct the device-tree for this device. Note that the MGBE driver still supports the legacy 'ptp-ref' clock name and so older/existing device-trees will still work, but given that this is not the correct name, there is no point to advertise this in the binding.

The energy performance preference field of the CPPC request MSR supports values from 0 to 255, but the strings only offer 4 values. The other values are useful for tuning the performance of some workloads. Add support for writing the raw energy performance preference value to the sysfs file.

2026-04-02cpufreq/amd-pstate: Add dynamic energy performance preferenceMario Limonciello (AMD)
Dynamic energy performance preference changes the EPP profile based on whether the machine is running on AC or DC power. A notification chain from the power supply core is used to adjust EPP values on plug in or plug out events. When enabled, the driver exposes a sysfs toggle for dynamic EPP, blocks manual writes to energy_performance_preference while it "owns" the EPP updates. For non-server systems: * the default EPP for AC mode is `performance`. * the default EPP for DC mode is `balance_performance`. For server systems dynamic EPP is mostly a no-op.

2026-04-02ASoC: qcom: q6dsp: few fixes and enhancementsMark Brown
Srinivas Kandagatla <srinivas.kandagatla@oss.qualcomm.com> says: This patchset contains few fixes for the bugs hit during testing with Monza EVK platform - around array out of bounds access on dai ids which keep extending but the drivers seems to have hardcoded some numbers, fix this and clean the mess up - fix few issues discovered while trying to shut down dsp. - flooding rpmsg with write requests due to not resetting queue pointer, fix this resetting the pointer in trigger stop. - possible multiple graph opens which can result in open failures. Apart from this few new enhancements to the dsp side - add new LPI MI2S and senary dai entries - handle pipewire and Displayport issues by moving graph start to trigger level, which should fix outstanding pipewire and DP issues on Qualcomm SoCs. - remove some unnessary loops in hot path - support early memory map on DSP. Tested this on top of linux-next on VENTUNO-Q platform.
