On mips ports, we already (unfortunately) have two types of paddr_t
(by _MIPS_PADDR_T_64BIT, even on 32bit mips) but AFAIK
there is no particular ABI issue among userland pkgsrc binaries.
The only place where paddr_t is exported to userland is <sys/mbuf.h>
but I don't know if such struct members are actually used in userland.
But, I agree it's better to make paddr_t always 64 bit,
if there is no ABI issue on the transition.
