2022-12-06libbpf: Parse usdt args without offset on x86 (e.g. 8@(%rsp))Timo Hunziker
Parse USDT arguments like "8@(%rsp)" on x86. These are emmited by SystemTap. The argument syntax is similar to the existing "memory dereference case" but the offset left out as it's zero (i.e. read the value from the address in the register). We treat it the same as the the "memory dereference case", but set the offset to 0. I've tested that this fixes the "unrecognized arg #N spec: 8@(%rsp).." error I've run into when attaching to a probe with such an argument. Attaching and reading the correct argument values works. Something similar might be needed for the other supported architectures.

2022-12-06hwmon: (emc2305) fix pwm never being able to set lowerXingjiang Qiao
There are fields 'last_hwmon_state' and 'last_thermal_state' in the structure 'emc2305_cdev_data', which respectively store the cooling state set by the 'hwmon' and 'thermal' subsystem, and the driver author hopes that if the state set by 'hwmon' is lower than the value set by 'thermal', the driver will just save it without actually setting the pwm. Currently, the 'last_thermal_state' also be updated by 'hwmon', which will cause the cooling state to never be set to a lower value. This patch fixes that.

2022-12-06cxl/security: Drop security command ioctl uapiDan Williams
CXL PMEM security operations are routed through the NVDIMM sysfs interface. For this reason the corresponding commands are marked "exclusive" to preclude collisions between the ioctl ABI and the sysfs ABI. However, a better way to preclude that collision is to simply remove the ioctl ABI (command-id definitions) for those operations. Now that cxl_internal_send_cmd() (formerly cxl_mbox_send_cmd()) no longer needs to talk the cxl_mem_commands array, all of the uapi definitions for the security commands can be dropped. These never appeared in a released kernel, so no regression risk.

2022-12-06cxl/mbox: Add variable output size validation for internal commandsDan Williams
cxl_internal_send_cmd() skips output size validation for variable output commands which is not ideal. Most of the time internal usages want to fail if the output size does not match what was requested. For other commands where the caller cannot predict the size there is usually a a header that conveys how much vaild data is in the payload. For those cases add @min_out as a parameter to specify what the minimum response payload needs to be for the caller to parse the rest of the payload. In this patch only Get Supported Logs has that behavior, but going forward records retrieval commands like Get Poison List and Get Event Records can use @min_out to retrieve a variable amount of records. Critically, this validation scheme skips the needs to interrogate the cxl_mem_commands array which in turn frees up the implementation to support internal command enabling without also enabling external / user commands.

2022-12-06cxl/mbox: Enable cxl_mbox_send_cmd() users to validate output sizeDan Williams
Internally cxl_mbox_send_cmd() converts all passed-in parameters to a 'struct cxl_mbox_cmd' instance and sends that to cxlds->mbox_send(). It then teases the possibilty that the caller can validate the output size. However, they cannot since the resulting output size is not conveyed to the called. Fix that by making the caller pass in a constructed 'struct cxl_mbox_cmd'. This prepares for a future patch to add output size validation on a per-command basis. Given the change in signature, also change the name to differentiate it from the user command submission path that performs more validation before generating the 'struct cxl_mbox_cmd' instance to execute.

"linux,initrd-start" and "linux,initrd-end" can be 32-bit values even on a 64-bit platform. Ideally, the size should be based on '#address-cells', but that has never been enforced in the kernel's FDT boot parsing code (early_init_dt_check_for_initrd()). Bootloader behavior is known to vary. For example, kexec always writes these as 64-bit. The result of incorrectly reading 32-bit values is most likely the reserved memory for the original initrd will still be reserved for the new kernel. The original arm64 equivalent of this code failed to release the initrd reserved memory in *all* cases. Use of_read_number() to mirror the early_init_dt_check_for_initrd() code.

2022-12-06dt-bindings: thermal: thermal-idle: Fix example pathsRob Herring
The reference by path (&{/cpus/cpu@101/thermal-idle}) in the example causes an error with new version of dtc: FATAL ERROR: Can't generate fixup for reference to path &{/cpus/cpu@100/thermal-idle} This is because the examples are built as an overlay and absolute paths are not valid as references must be by label. The path was also not resolvable because, by default, examples are placed under 'example-N' nodes. As the example contains top-level nodes, the root node must be explicit for the example to be extracted as-is. This changes the indentation for the whole example, but the existing indentation is a mess of of random amounts. Clean this up to be 4 spaces everywhere.

2022-12-06selftests/bpf: Allow building bpf tests with CONFIG_XFRM_INTERFACE=[m|n]Martin KaFai Lau
It is useful to use vmlinux.h in the xfrm_info test like other kfunc tests do. In particular, it is common for kfunc bpf prog that requires to use other core kernel structures in vmlinux.h Although vmlinux.h is preferred, it needs a ___local flavor of struct bpf_xfrm_info in order to build the bpf selftests when CONFIG_XFRM_INTERFACE=[m|n].

2022-12-06riscv, bpf: Emit fixed-length instructions for BPF_PSEUDO_FUNCPu Lehui
For BPF_PSEUDO_FUNC instruction, verifier will refill imm with correct addresses of bpf_calls and then run last pass of JIT. Since the emit_imm of RV64 is variable-length, which will emit appropriate length instructions accorroding to the imm, it may broke ctx->offset, and lead to unpredictable problem, such as inaccurate jump. So let's fix it with fixed-length instructions.

2022-12-06clk: qcom: mmcc-msm8974: use parent_hws/_data instead of parent_namesDmitry Baryshkov
Convert the clock driver to specify parent data rather than parent names, to actually bind using 'clock-names' specified in the DTS rather than global clock names. Use parent_hws where possible to refer parent clocks directly, skipping the lookup. Note, the system names for xo clocks were changed from "xo" to "xo_board" to follow the example of other platforms. This switches the clocks to use DT-provided "xo_board" clock instead of manually registered "xo" clock and allows us to drop qcom_cc_register_board_clk() call from the driver at some point.
