So I ended up looking into other trace_symbols too and I don't think we
should have a trailing comma here. It may cause some issues silently in
trace-cmd or other places. I remember going through it when I was doing
some other tracing work earlier but I don't recollect it now.

Can we just remove the trailing comma and send a v2 please?

btw, 0XF80 is correct as per "arch/powerpc/include/asm/kvm_asm.h"

#define BOOK3S_INTERRUPT_H_FAC_UNAVAIL  0xf80
