Have you see my question to the first version of this patch?

Hello,
The functions were removed in this patch : https://lore.kernel.org/linux-pci/20240322164139.678228-1-cassel@kernel.org/
So in linux-next they are indeed not used anymore.

You applied it to misc : https://lore.kernel.org/linux-pci/20240517100929.GB202520@rocinante/

Regards,
Rick

Ahh, it was sometime in May...  I assumed we already got this into the
mainline, hence my confusion.  Hard to remember what went out when.

Also, I looked only at our head branch first, as I always do, before
I noticed the updated tag.

Thank you for getting back to me.  Appreciated.

I will get this applied against our pending "misc" branch, should sort
out the warnings on next.

Yeah, I don't understand this at all, how is this patch even building?

What tree/branch is it made against?

thanks,

Hi,
I can confirm in linux-next tag next-20240703 the functions are indeed removed.
See commit 0ace3d3b70ed6a474d52fc44ee9b0b1f16ca3724
misc: pci_endpoint_test: Use memcpy_toio()/memcpy_fromio() for BAR tests
