There was a series about 6 months ago making use of the new DGH arm64
instruction in a network driver:
https://lore.kernel.org/r/1627614864-50824-1-git-send-email-huangguangbin2@xxxxxxxxxx
We bike-shedded on the name of the macro since (now settled on
io_stop_wc()) and there wasn't much point in carrying the rest of the
patches. I assume the driver changes will go in via their normal route
once the macro above is merged.
