I am now reliably informed that mphys() is actually a deprecated
interface; applications should be using mem_offset() and/or
mem_offset64() instead.

Looks like the prototype is missing altogether.  I've raised PR 73826 to
fix this in 642.  For earlier releases the workaround is to use:

        extern paddr_t mphys(void *);
