2022-07-13scsi: ufs: core: Drop loglevel of WriteBoost messageBjorn Andersson
Commit '3b5f3c0d0548 ("scsi: ufs: core: Tidy up WB configuration code")' changed the log level of the write boost enable/disable notification from debug to info. This results in a lot of noise in the kernel log during normal operation. Drop it back to debug level to avoid this.

2022-07-13scsi: megaraid: Clear READ queue map's nr_queuesMing Lei
The megaraid SCSI driver sets set->nr_maps as 3 if poll_queues is > 0, and blk-mq actually initializes each map's nr_queues as nr_hw_queues. Consequently the driver has to clear READ queue map's nr_queues, otherwise the queue map becomes broken if poll_queues is set as non-zero.

2022-07-13sfc: fix use after free when disabling sriovÍñigo Huguet
Use after free is detected by kfence when disabling sriov. What was read after being freed was vf->pci_dev: it was freed from pci_disable_sriov and later read in efx_ef10_sriov_free_vf_vports, called from efx_ef10_sriov_free_vf_vswitching. Set the pointer to NULL at release time to not trying to read it later.

2022-07-13smb3: workaround negprot bug in some Samba serversSteve French
Mount can now fail to older Samba servers due to a server bug handling padding at the end of the last negotiate context (negotiate contexts typically are rounded up to 8 bytes by adding padding if needed). This server bug can be avoided by switching the order of negotiate contexts, placing a negotiate context at the end that does not require padding (prior to the recent netname context fix this was the case on the client).

2022-07-13ACPI: CPPC: Fix enabling CPPC on AMD systems with shared memoryMario Limonciello
When commit 72f2ecb7ece7 ("ACPI: bus: Set CPPC _OSC bits for all and when CPPC_LIB is supported") was introduced, we found collateral damage that a number of AMD systems that supported CPPC but didn't advertise support in _OSC stopped having a functional amd-pstate driver. The _OSC was only enforced on Intel systems at that time. This was fixed for the MSR based designs by commit 8b356e536e69f ("ACPI: CPPC: Don't require _OSC if X86_FEATURE_CPPC is supported") but some shared memory based designs also support CPPC but haven't advertised support in the _OSC. Add support for those designs as well by hardcoding the list of systems.

2022-07-13fs/remap: constrain dedupe of EOF blocksDave Chinner
If dedupe of an EOF block is not constrainted to match against only other EOF blocks with the same EOF offset into the block, it can match against any other block that has the same matching initial bytes in it, even if the bytes beyond EOF in the source file do not match. Fix this by constraining the EOF block matching to only match against other EOF blocks that have identical EOF offsets and data. This allows "whole file dedupe" to continue to work without allowing eof blocks to randomly match against partial full blocks with the same data.

2022-07-13drm/amd/display: Only use depth 36 bpp linebuffers on DCN display engines.Mario Kleiner
Various DCE versions had trouble with 36 bpp lb depth, requiring fixes, last time in commit 353ca0fa5630 ("drm/amd/display: Fix 10bit 4K display on CIK GPUs") for DCE-8. So far >= DCE-11.2 was considered ok, but now I found out that on DCE-11.2 it causes dithering when there shouldn't be any, so identity pixel passthrough with identity gamma LUTs doesn't work when it should. This breaks various important neuroscience applications, as reported to me by scientific users of Polaris cards under Ubuntu 22.04 with Linux 5.15, and confirmed by testing it myself on DCE-11.2. Lets only use depth 36 for DCN engines, where my testing showed that it is both necessary for high color precision output, e.g., RGBA16 fb's, and not harmful, as far as more than one year in real-world use showed. DCE engines seem to work fine for high precision output at 30 bpp, so this ("famous last words") depth 30 should hopefully fix all known problems without introducing new ones. Successfully retested on DCE-11.2 Polaris and DCN-1.0 Raven Ridge on top of Linux 5.19.0-rc2 + drm-next.

2022-07-13hwmon: (asus_wmi_sensors) Save a few bytes of memoryChristophe JAILLET
The first 'for' loop of asus_wmi_configure_sensor_setup() only computes the number and type of sensors that exist in the system. Here, the 'temp_sensor' structure is only used to store the data collected by asus_wmi_sensor_info(). There is no point in using a devm_ variant for this allocation. This wastes some memory for no good reason. Use the stack instead.

2022-07-13hwmon: (dell-smm) Improve assembly codeArmin Wolf
The new assembly code works on both 32 bit and 64 bit cpus and allows for more compiler optimisations. Since clang runs out of registers on 32 bit x86 when using CC_OUT, we need to execute "setc" ourself. Also modify the debug message so we can still see the result (eax) when the carry flag was set. Tested with 32 bit and 64 bit kernels on a Dell Inspiron 3505.

2022-07-13hwmon: (pmbus/ltc2978) Set voltage resolutionMårten Lindahl
The LTC2977 regulator does not set the regulator_desc .n_voltages value which is needed in order to let the regulator core list the regulator voltage range. This patch defines a regulator_desc with a voltage range, and uses it for defining voltage resolution for regulators LTC2972/LTC2974/LTC2975/ LTC2977/LTC2978/LTC2979/LTC2980/LTM2987 based on that they all have a 16 bit ADC with the same stepwise 122.07uV resolution. It also scales the resolution to a 1mV resolution which is easier to handle.

2022-07-13hwmon: (pmbus) Introduce and use cached vout marginsMårten Lindahl
When setting a new voltage the voltage boundaries are read every time to check that the new voltage is within the proper range. Checking these voltage boundaries consists of reading one of PMBUS_MFR_VOUT_MIN/ PMBUS_VOUT_MARGIN_LOW registers and then PMBUS_MFR_VOUT_MAX/ PMBUS_VOUT_MARGIN_HIGH together with writing the PMBUS_CLEAR_FAULTS register. Since these boundaries are never being changed, it can be cached and thus saving unnecessary smbus transmissions.
