While ultimately it's the Arm maintainers to judge, may I suggest that
these be put in arm/domain.c to limit visibility?
In general, I am not in favor of declaring prototype outside of headers.
That said, I would be okay with it for the two prototypes because:
1) they are prototypes for assembly functions
2) declaring in current.h sounds wrong. A better place would be
domain.h but this would not reduce the visibility too much
3) this is unlikely to be used by other part of Xen
