Applied this patch on top, thanks for the report! Arnd commit fdc5bebfb66bf0d261818c2df2b01c2a005791fe Author: Arnd Bergmann <arnd@xxxxxxxx> Date: Mon Sep 12 21:27:19 2022 +0200 parisc: hide ioread64 declaration on 32-bit The definition of ioread64 etc is hidden on 32-bit, but the declaration remained by accident, which led to the generic definition getting left out: ERROR: modpost: "ioread64" [drivers/pci/switch/switchtec.ko] undefined! Hide the declaration and #define under the same #ifdef.
