2023-06-21docs: arm64: Move arm64 documentation under Documentation/arch/Jonathan Corbet
Architecture-specific documentation is being moved into Documentation/arch/ as a way of cleaning up the top-level documentation directory and making the docs hierarchy more closely match the source hierarchy. Move Documentation/arm64 into arch/ (along with the Chinese equvalent translations) and fix up documentation references.

2023-06-21net: micrel: Change to receive timestamp in the frame for lan8841Horatiu Vultur
Currently for each timestamp frame, the SW needs to go and read the received timestamp over the MDIO bus. But the HW has the capability to store the received nanoseconds part and the least significant two bits of the seconds in the reserved field of the PTP header. In this way we could save few MDIO transactions (actually a little more transactions because the access to the PTP registers are indirect) for each received frame. Instead of reading the rest of seconds part of the timestamp of the frame using MDIO transactions schedule PTP worker thread to read the seconds part every 500ms and then for each of the received frames use this information. Because if for example running with 512 frames per second, there is no point to read 512 times the second part. Doing all these changes will give a great CPU usage performance. Running ptp4l with logSyncInterval of -9 will give a ~60% CPU improvement.

2023-06-21blk-mq: don't insert passthrough request into sw queueMing Lei
In case of real io scheduler, q->elevator is set, so blk_mq_run_hw_queue() may just check if scheduler queue has request to dispatch, see __blk_mq_sched_dispatch_requests(). Then IO hang may be caused because all passthorugh requests may stay in sw queue. And any passthrough request should have been inserted to hctx->dispatch always.

We cannot sanely handle partial retries for recvmsg if we have cmsg attached. If we don't, then we'd just be overwriting the initial cmsg header on retries. Alternatively we could increment and handle this appropriately, but it doesn't seem worth the complication. Move the MSG_WAITALL check into the non-multishot case while at it, since MSG_WAITALL is explicitly disabled for multishot anyway.

Although including linux/irqchip/mxs.h is technically correct, this clashes with the parallel removal of this include file with 32bit ARM modernizing the low level irq handling as part of 5bb578a0c1b8 ("ARM: 9298/1: Drop custom mdesc->handle_irq()").

2023-06-21arm64: hibernate: remove WARN_ON in save_processor_stateSong Shuai
During hibernation or restoration, freeze_secondary_cpus checks num_online_cpus via BUG_ON, and the subsequent save_processor_state also does the checking with WARN_ON. In the case of CONFIG_PM_SLEEP_SMP=n, freeze_secondary_cpus is not defined, but the sole possible condition to disable CONFIG_PM_SLEEP_SMP is !SMP where num_online_cpus is always 1. We also don't have to check it in save_processor_state. So remove the unnecessary checking in save_processor_state.

2023-06-21wifi: iwlwifi: mvm: Add support for IGTK in D3 resume flowYedidya Benshimol
As part of the new security API in the FW, all security keys are to be removed before station removal. Until now IGTK rekey wasn't supported in the D3 resume flow, and thus the driver might not know the right key to remove. If an IGTK was rekeyed during D3 the old IGTK is removed and the new key is updated. If not, the old key's IPN is updated. As opposed to GTK, which both the FW and the driver hold it's two most recent keys, only one IGTK is held.

2023-06-21wifi: iwlwifi: split 22000.c into multiple filesJohannes Berg
Split the configuration list in 22000.c into four new files, per new device family, so we don't have this huge unusable file. Yes, this duplicates a few small things, but that's still much better than what we have now.

2023-06-21wifi: iwlwifi: mvm: check only affected linksJohannes Berg
When hostapd starts up, it may start up with only one link while the other is still scanning for overlapping BSSes. A station might start to connect at this point, but we run into this warning instead. Since there's no need to check for _all_ links, restrict the check to just the affected links that the STA will be using.

2023-06-21wifi: iwlwifi: mvm: avoid baid size integer overflowJohannes Berg
Roee reported various hard-to-debug crashes with pings in EHT aggregation scenarios. Enabling KASAN showed that we access the BAID allocation out of bounds, and looking at the code a bit shows that since the reorder buffer entry (struct iwl_mvm_reorder_buf_entry) is 128 bytes if debug such as lockdep is enabled, then staring from an agg size 512 we overflow the size calculation, and allocate a much smaller structure than we should, causing slab corruption once we initialize this. Fix this by simply using u32 instead of u16.
