2024-09-04platform/x86: ideapad-laptop: Make the scope_guard() clear of its scopeAndy Shevchenko
First of all, it's a bit counterintuitive to have something like int err; ... scoped_guard(...) err = foo(...); if (err) return err; Second, with a particular kernel configuration and compiler version in one of such cases the objtool is not happy: ideapad-laptop.o: warning: objtool: .text.fan_mode_show: unexpected end of section I'm not an expert on all this, but the theory is that compiler and linker in this case can't understand that 'result' variable will be always initialized as long as no error has been returned. Assigning 'result' to a dummy value helps with this. Note, that fixing the scoped_guard() scope (as per above) does not make issue gone. That said, assign dummy value and make the scope_guard() clear of its scope. For the sake of consistency do it in the entire file.

Add efficiency latency control support to the TPMI uncore driver. This defines two new threshold values for controlling uncore frequency, low threshold and high threshold. When CPU utilization is below low threshold, the user configurable floor latency control frequency can be used by the system.

2024-09-04platform/x86: lenovo-ymc: Ignore the 0x0 stateGergo Koteles
While booting, Lenovo 14ARB7 reports 'lenovo-ymc: Unknown key 0 pressed' warning. This is caused by lenovo_ymc_probe() calling lenovo_ymc_notify() at probe time to get the initial tablet-mode-switch state and the key-code lenovo_ymc_notify() reads from the firmware is not initialized at probe time yet on the Lenovo 14ARB7. The hardware/firmware does an ACPI notify on the WMI device itself when it initializes the tablet-mode-switch state later on. Add 0x0 YMC state to the sparse keymap to silence the warning.

The commit 'b1d90a86 ("drm/xe: Use the encoder suspend helper also used by the i915 driver")' didn't do anything wrong. It actually fixed a critical bug, because the encoder_suspend was never getting actually called because it was returning if (has_display(xe)) instead of if (!has_display(xe)). However, this ended up introducing the encoder suspend calls in the runtime routines as well, causing the circular locking dependency.

2024-09-05PM / devfreq: exynos: Use Use devm_clk_get_enabled() helpersAnand Moon
The devm_clk_get_enabled() helpers: - call devm_clk_get() - call clk_prepare_enable() and register what is needed in order to call clk_disable_unprepare() when needed, as a managed resource. This simplifies the code and avoids the calls to clk_disable_unprepare(). While at it, use dev_err_probe consistently, and use its return value to return the error code.

2024-09-04arm64: trans_pgd: mark PTEs entries as valid to avoid dead kexec()Fares Mehanna
The reasons for PTEs in the kernel direct map to be marked invalid are not limited to kfence / debug pagealloc machinery. In particular, memfd_secret() also steals pages with set_direct_map_invalid_noflush(). When building the transitional page tables for kexec from the current kernel's page tables, those pages need to become regular writable pages, otherwise, if the relocation places kexec segments over such pages, a fault will occur during kexec, leading to host going dark during kexec. This patch addresses the kexec issue by marking any PTE as valid if it is not none. While this fixes the kexec crash, it does not address the security concern that if processes owning secret memory are not terminated before kexec, the secret content will be mapped in the new kernel without being scrubbed.

2024-09-04cpufreq: ti-cpufreq: Introduce quirks to handle syscon fails appropriatelyNishanth Menon
Commit b4bc9f9e27ed ("cpufreq: ti-cpufreq: add support for omap34xx and omap36xx") introduced special handling for OMAP3 class devices where syscon node may not be present. However, this also creates a bug where the syscon node is present, however the offset used to read is beyond the syscon defined range. Fix this by providing a quirk option that is populated when such special handling is required. This allows proper failure for all other platforms when the syscon node and efuse offsets are mismatched.

2024-09-04perf/arm-cmn: Support CMN S3Robin Murphy
CMN S3 is the latest and greatest evolution for 2024, although most of the new features don't impact the PMU, so from our point of view it ends up looking a lot like CMN-700 r3 still. We have some new device types to ignore, a mildly irritating rearrangement of the register layouts, and a scary new configuration option that makes it potentially unsafe to even walk the full discovery tree, let alone attempt to use the PMU.
