albeit I'd have expected the file to by part of the XENTRACE
section of ./MAINTAINERS.

Would be nice if the u32-s here could go away at the same time.
Ideally they'd become unsigned int, but I guess you're once
again rather seeing them be uint32_t.

Also wouldn't you better adjust __trace_var()'s definition as well
at this occasion?
