Tested working on C740 (mine).

Tested working on C710 (https://old.reddit.com/r/chrultrabook/comments/jut1kh/acer_c710_fn_key/gcg118f/).

Notes:

iwlmvm swcrypto refusal

$ dmesg
[...]
[ 1060.780921] iwlwifi 0000:01:00.0: iwlmvm doesn't allow to disable HW crypto, check swcrypto module parameter

This is because of:

labby@galliumos:/etc/modprobe.d$ cat iwlwifi-opts.conf 
options iwlwifi swcrypto=1
labby@galliumos:/etc/modprobe.d$ dpkg -S /etc/modprobe.d/iwlwifi-opts.conf
galliumos-broadwell: /etc/modprobe.d/iwlwifi-opts.conf

I don't know of any issues with hwcrypto on iwlwifi chips since a long time. Based on the original commit it does sound like this is mostly for iwldvm chips, the early ones of which did have hw crypto issues.

So I think we should probably get rid of that option in galliumos-broadwell packages (et. al.)

ibmvnic: fix NULL pointer dereference in reset_sub_crq_queues

adapter->tx_scrq and adapter->rx_scrq could be NULL if the previous reset

s390/dasd: fix null pointer dereference for ERP requests
6f117cb 
When requeueing all requests on the device request queue to the blocklayer
we might get to an ERP (error recovery) request that is a copy of an
original CQR.

Those requests do not have blocklayer request information or a pointer to
the dasd_queue set. When trying to access those data it will lead to a
null pointer dereference in dasd_requeue_all_requests().

Fix by checking if the request is an ERP request that can simply be
ignored. The blocklayer request will be requeued by the original CQR that
is on the device queue right behind the ERP request.

Fixes: 9487cfd ("s390/dasd: fix handling of internal requests")

perf test: Avoid an msan warning in a copied stack.
568beb2 
This fix is for a failure that occurred in the DWARF unwind perf test.

Stack unwinders may probe memory when looking for frames.

Memory sanitizer will poison and track uninitialized memory on the
stack, and on the heap if the value is copied to the heap.

This can lead to false memory sanitizer failures for the use of an
uninitialized value.

Avoid this problem by removing the poison on the copied stack.

The full msan failure with track origins looks like:

dmaengine: pl330: _prep_dma_memcpy: Fix wrong burst size
e773ca7 
Actually, burst size is equal to '1 << desc->rqcfg.brst_size'.
we should use burst size, not desc->rqcfg.brst_size.

dma memcpy performance on Rockchip RV1126
@ 1512MHz A7, 1056MHz LPDDR3, 200MHz DMA:
