Thanks, Steven. Could we look into the EPD* caching microarch details
Marc was referring to for these A55 and A76 cores?

If the behaviour is the same as A57/A72 then it sounds safe. Otherwise,
there'll need to be some invalidation to avoid that issue.

And thanks for the pointer to your previous patch, it's a very helpful
reference.
