I see no bitwise ops on signed values here.

fpcrval.u64 is uint64_t.  After the "integer promotions",
it's still uint64_t (unless that's smaller than int, which is not 
the case for any existing NetBSD port).  After >>58, it's still 
uint64_t.  0x3 is a signed int, but the "usual arithmetic conversions"
should convert it to uint64_t.
