2023-04-14objtool: Include weak functions in global_noreturns checkJosh Poimboeuf
If a global function doesn't return, and its prototype has the __noreturn attribute, its weak counterpart must also not return so that it matches the prototype and meets call site expectations. To properly follow the compiled control flow at the call sites, change the global_noreturns check to include both global and weak functions. On the other hand, if a weak function isn't in global_noreturns, assume the prototype doesn't have __noreturn. Even if the weak function doesn't return, call sites treat it like a returnable function.

2023-04-14HID: wacom: generic: Set battery quirk only when we see battery dataJason Gerecke
Some devices will include battery status usages in the HID descriptor but we won't see that battery data for one reason or another. For example, AES sensors won't send battery data unless an AES pen is in proximity. If a user does not have an AES pen but instead only interacts with the AES touchscreen with their fingers then there is no need for us to create a battery object. Similarly, if a family of peripherals shares the same HID descriptor between wired-only and wireless-capable SKUs, users of the former may never see a battery event and will not want a power_supply object created.

2023-04-14HID: wacom: Lazy-init batteriesJason Gerecke
Rather than creating batteries as part of the initial device probe, let's make the process lazy. This gives us the opportunity to prevent batteries from being created in situations where they are unnecessary. There are two cases in particular where batteries are being unnecessarily created at initialization. These are AES sensors (for which we don't know any battery status information until a battery-powered pen actually comes into prox) peripheral tablets which share HID descriptors between the wired-only and wireless-capable SKUs of a family of devices. This patch will delay battery initialization of the former until a pen actually comes into prox. It will delay battery initialization of the latter until either a pen comes into prox or a "heartbeat" packet is processed.

2023-04-14perf/core: Fix hardlockup failure caused by perf throttleYang Jihong
commit e050e3f0a71bf ("perf: Fix broken interrupt rate throttling") introduces a change in throttling threshold judgment. Before this, compare hwc->interrupts and max_samples_per_tick, then increase hwc->interrupts by 1, but this commit reverses order of these two behaviors, causing the semantics of max_samples_per_tick to change. In literal sense of "max_samples_per_tick", if hwc->interrupts == max_samples_per_tick, it should not be throttled, therefore, the judgment condition should be changed to "hwc->interrupts > max_samples_per_tick". In fact, this may cause the hardlockup to fail, The minimum value of max_samples_per_tick may be 1, in this case, the return value of __perf_event_account_interrupt function is 1. As a result, nmi_watchdog gets throttled, which would stop PMU (Use x86 architecture as an example, see x86_pmu_handle_irq).

The patch had been sitting there for months and I only re-found it recently, so you can guess how much of a "fix" it actually is. It'll become needed when the system controller's QSPI gets added in the future, but at present there's no urgency as the driver can handle both the current and "fixed" versions. StarFive: Basic support for the JH7110 & the associated first-party dev board, the VisionFive v2 (in two forms). There's a bunch of dt-bindings required for this too, all of which have had input from the DT folk. There's enough in this tag to boot to a console w/ an initramfs but little more.

2023-04-14perf/arm-cmn: Fix port detection for CMN-700Robin Murphy
When the "extra device ports" configuration was first added, the additional mxp_device_port_connect_info registers were added around the existing mxp_mesh_port_connect_info registers. What I missed about CMN-700 is that it shuffled them around to remove this discontinuity. As such, tweak the definitions and factor out a helper for reading these registers so we can deal with this discrepancy easily, which does at least allow nicely tidying up the callsites. With this we can then also do the nice thing and skip accesses completely rather than relying on RES0 behaviour where we know the extra registers aren't defined.

2023-04-14arm64: kgdb: Set PSTATE.SS to 1 to re-enable single-stepSumit Garg
Currently only the first attempt to single-step has any effect. After that all further stepping remains "stuck" at the same program counter value. Refer to the ARM Architecture Reference Manual (ARM DDI 0487E.a) D2.12, PSTATE.SS=1 should be set at each step before transferring the PE to the 'Active-not-pending' state. The problem here is PSTATE.SS=1 is not set since the second single-step. After the first single-step, the PE transferes to the 'Inactive' state, with PSTATE.SS=0 and MDSCR.SS=1, thus PSTATE.SS won't be set to 1 due to kernel_active_single_step()=true. Then the PE transferes to the 'Active-pending' state when ERET and returns to the debugger by step exception.

So far io_req_complete_post() only covers DEFER_TASKRUN by completing request via task work when the request is completed from IOWQ. However, uring command could be completed from any context, and if io uring is setup with DEFER_TASKRUN, the command is required to be completed from current context, otherwise wait on IORING_ENTER_GETEVENTS can't be wakeup, and may hang forever. The issue can be observed on removing ublk device, but turns out it is one generic issue for uring command & DEFER_TASKRUN, so solve it in io_uring core code.

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.4 The Qualcomm SCM driver will now always clear the download bit, avoiding entering download mode on a clean reboot because the bootloader left it set. The vmid bitmap passed to qcom_scm_assign_mem() is transitioned to a well defined size. SM6375 support is added, and SC8180X, QDU1000/QRU1000, IPQ5332 and IPQ9574 compatibles are documented. GENI gains support for newer hardware with deeper FIFOs. The BWMON driver is updated to better handle the two register blocks, which are not consistent between MSM8998 and newer platforms. The LLCC driver no longer assumes a fixes stride across the various banks, and instead acquire the bank placement from DeviceTree. EDAC support for polling is introduced. EDAC support on SDM845 is disabled, as its been observed that accessing relevant registers is not permitted on most devices. PMIC GLINK is reworked to support defining which auxiliary children to spawn per platform, support for spawning a UCSI child is added and SM8450 and SM8550 is introduced. The RPM power-domain driver is cleaned up by moving and generalizing structures that are common between platforms, rather than duplicating everything. Macros are replaced with just direct definition of the relevant structures. Support for defining parent relationships between the power-domains is introduced, like it has been in rpmhpd for a long time. Number of processors has gone up, so max processor count in SMEM is bumped again. Error handling in SMSM is cleaned up using dev_err_probe(). Socinfo is taught about IPQ9574, QCM2290, QRB2210, QRB4210, SM7150, SA8775P and a number of PMICs. * tag 'qcom-drivers-for-6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (51 commits) dt-bindings: firmware: document Qualcomm SC8180X SCM dt-bindings: sram: qcom,imem: document SM6375 IMEM soc: qcom: icc-bwmon: Handle global registers correctly soc: qcom: icc-bwmon: Remove unused struct member soc: qcom: smsm: Use dev_err_probe() firmware: qcom_scm: Add SM6375 compatible soc: qcom: llcc: Add configuration data for SM7150 dt-bindings: arm: msm: Add LLCC for SM7150 dt-bindings: soc: qcom: smd-rpm: re-add missing qcom,rpm-msm8994 soc: qcom: pmic_glink: register ucsi aux device dt-bindings: soc: qcom: qcom,pmic-glink: document SM8550 compatible dt-bindings: soc: qcom: qcom,pmic-glink: document SM8450 compatible firmware: qcom_scm: Clear download bit during reboot dt-bindings: soc: qcom: aoss: Document QDU1000/QRU1000 compatible dt-bindings: firmware: qcom,scm: Update QDU1000/QRU1000 compatible dt-bindings: soc: qcom: smd-rpm: Add IPQ9574 compatible firmware: qcom_scm: Use fixed width src vm bitmap dt-bindings: firmware: qcom,scm: document IPQ5332 SCM dt-bindings: scm: Add compatible for IPQ9574 soc: qcom: rpmpd: Remove useless comments ...
