2021-12-28drm/amd/display: Fix USB4 null pointer dereference in update_psp_stream_configNicholas Kazlauskas
[Why] A porting error on a previous patch left the block of code that causes the crash from a NULL pointer dereference. More specifically, we try to access link_enc before it's assigned in the USB4 case in the following assignment: config.dio_output_idx = link_enc->transmitter - TRANSMITTER_UNIPHY_A; [How] That assignment occurs later depending on the ASIC version. It's only needed on DCN31 and only after link_enc is already assigned.

[Why] We'll exit optimized power state to do link detection but we won't enter back into the optimized power state.

2021-12-28drm/amdgpu: Don't inherit GEM object VMAs in child processRajneesh Bhardwaj
When an application having open file access to a node forks, its shared mappings also get reflected in the address space of child process even though it cannot access them with the object permissions applied. With the existing permission checks on the gem objects, it might be reasonable to also create the VMAs with VM_DONTCOPY flag so a user space application doesn't need to explicitly call the madvise(addr, len, MADV_DONTFORK) system call to prevent the pages in the mapped range to appear in the address space of the child process. It also prevents the memory leaks due to additional reference counts on the mapped BOs in the child process that prevented freeing the memory in the parent for which we had worked around earlier in the user space inside the thunk library. Additionally, we faced this issue when using CRIU to checkpoint restore an application that had such inherited mappings in the child which confuse CRIU when it mmaps on restore. Having this flag set for the render node VMAs helps. VMAs mapped via KFD already take care of this so this is needed only for the render nodes. To limit the impact of the change to user space consumers such as OpenGL etc, limit it to KFD BOs only.

2021-12-28ACPI: sysfs: use default_groups in kobj_typeGreg Kroah-Hartman
There are currently 2 ways to create a set of sysfs files for a kobj_type, through the default_attrs field, and the default_groups field. Move the ACPI sysfs code to use default_groups field which has been the preferred way since aa30f47cf666 ("kobject: Add support for default attribute groups to kobj_type") so that we can soon get rid of the obsolete default_attrs field.

2021-12-28igc: Do not enable crosstimestamping for i225-V modelsVinicius Costa Gomes
It was reported that when PCIe PTM is enabled, some lockups could be observed with some integrated i225-V models. While the issue is investigated, we can disable crosstimestamp for those models and see no loss of functionality, because those models don't have any support for time synchronization.
