I've just posted "[PATCH 0/7] tee: shared memory updates",
https://lore.kernel.org/lkml/20210609102324.2222332-1-jens.wiklander@linaro.org/ (local)

Where tee_shm_alloc() is replaced by among other functions
tee_shm_alloc_kernel_buf(). tee_shm_alloc_kernel_buf() takes care of the
problem with TEE_SHM_DMA_BUF.

Thanks! At first glance, that series would take care of the last three
patches in my kexec/kdump series.

Correction: Your series would not completely take care of the last three
patches in my kexec/kdump series because your series doesn't implement
the .shutdown() hook for tee_bnxt_fw.

Does it make sense to take my series first and then rebase your series
on top of it? That would allow my fixes to flow back to stable, then
your changes would greatly clean up the implementation in future
releases.

Yes, we could try that. I'd like to see tee_shm_alloc_kernel_buf() being
used instead of tee_shm_alloc() in ftpm_tee_probe() and
tee_bnxt_fw_probe(). So it would be great if you could include "tee: add
tee_shm_alloc_kernel_buf()" in your patch set.

My patch set would then shrink a bit. By the way, thanks for reviewing
it.

Cheers,
Jens
