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.

2021-12-28drm/amdgpu: Send Message to SMU on aldebaran passthrough for sbr handlingsashank saye
For Aldebaran chip passthrough case we need to intimate SMU about special handling for SBR.On older chips we send LightSBR to SMU, enabling the same for Aldebaran. Slight difference, compared to previous chips, is on Aldebaran, SMU would do a heavy reset on SBR. Hence, the word Heavy instead of Light SBR is used for SMU to differentiate.

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.

2021-12-28e1000: switch to napi_consume_skb()Alexander Lobakin
In order to take the best from per-cpu NAPI skbuff_head caches and CPU cycles, let's switch from dev_kfree_skb_any(), which passes skb back to the mm layer, to napi_consume_skb(), which feeds those caches on non-zero budget instead (falls back to the former on 0). Do the replacement in e1000_unmap_and_free_tx_resource(). There are 4 call sites of this function throughout the driver: * e1000_clean_tx_ring(). Slowpath, process context, cleans the whole Tx ring on ifdown. Use budget of 0 here; * e1000_tx_map(). Hotpath, net Tx softirq, unmaps the buffers in case of error. Use 0 as well; * e1000_clean_tx_irq(). Hotpath, NAPI Tx completion polling cycle. As the driver doesn't count completed Tx entries towards the NAPI budget, just use the poll budget of 64 to utilize caches. Apart from being a preparation for switching to napi_build_skb(), this is useful on its own as well, as napi_consume_skb() flushes skb caches by batches of 32 instead of one-at-a-time.

2021-12-28staging: r8188eu: FAT_State is always FAT_NORMAL_STATEMichael Straube
In this driver pDM_FatTable->FAT_State is always FAT_NORMAL_STATE. So the check 'if (pDM_FatTable->FAT_State == FAT_TRAINING_STATE)' is always false. Remove dead code that is executed only if that check is true.
