2022-12-06hwmon: (emc2305) fix unable to probe emc2301/2/3Xingjiang Qiao
The definitions of 'EMC2305_REG_PRODUCT_ID' and 'EMC2305_REG_DEVICE' are both '0xfd', they actually return the same value, but the values returned by emc2301/2/3/5 are different, so probe emc2301/2/3 will fail, 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.

2022-12-06of/kexec: Fix reading 32-bit "linux,initrd-{start,end}" valuesRob Herring
"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.
