It resolves a build issue that many people were hitting with your current tree, and Kees and others felt would be good to get merged before -rc1 comes out, to prevent them from having to constantly hit it as many development trees restart on -rc1, not older -rc releases.

2021-09-10of: property: Disable fw_devlink DT support for X86Saravana Kannan1-0/+3
Andre reported fw_devlink=on breaking OLPC XO-1.5 [1]. OLPC XO-1.5 is an X86 system that uses a mix of ACPI and OF to populate devices. The root cause seems to be ISA devices not setting their fwnode field. But trying to figure out how to fix that doesn't seem worth the trouble because the OLPC devicetree is very sparse/limited and fw_devlink only adds the links causing this issue. Considering that there aren't many users of OF in an X86 system, simply fw_devlink DT support for X86.

2021-09-10drm/ttm: Fix a deadlock if the target BO is not idle during swapxinhui pan1-3/+3
The ret value might be -EBUSY, caller will think lru lock is still locked but actually NOT. So return -ENOSPC instead. Otherwise we hit list corruption. ttm_bo_cleanup_refs might fail too if BO is not idle. If we return 0, caller(ttm_tt_populate -> ttm_global_swapout ->ttm_device_swapout) will be stuck as we actually did not free any BO memory. This usually happens when the fence is not signaled for a long time.

2021-09-09thermal/drivers/qcom/spmi-adc-tm5: Don't abort probing if a sensor is not usedMatthias Kaehlcke1-0/+6
adc_tm5_register_tzd() registers the thermal zone sensors for all channels of the thermal monitor. If the registration of one channel fails the function skips the processing of the remaining channels and returns an error, which results in _probe() being aborted. One of the reasons the registration could fail is that none of the thermal zones is using the channel/sensor, which hardly is a critical error (if it is an error at all). If this case is detected emit a warning and continue with processing the remaining channels.

2021-09-09iommu: Clarify default domain KconfigRobin Murphy1-1/+1
Although strictly it is the AMD and Intel drivers which have an existing expectation of lazy behaviour by default, it ends up being rather unintuitive to describe this literally in Kconfig. Express it instead as an architecture dependency, to clarify that it is a valid config-time decision. The end result is the same since virtio-iommu doesn't support lazy mode and thus falls back to strict at runtime regardless. The per-architecture disparity is a matter of historical expectations: the AMD and Intel drivers have been lazy by default since 2008, and changing that gets noticed by people asking where their I/O throughput has gone. Conversely, Arm-based systems with their wider assortment of IOMMU drivers mostly only support strict mode anyway; only the Arm SMMU drivers have later grown support for passthrough and lazy mode, for users who wanted to explicitly trade off isolation for performance. These days, reducing the default level of isolation in a way which may go unnoticed by users who expect otherwise hardly seems worth risking for the sake of one line of Kconfig, so here's where we are.
