Perhaps I could have expressed that more clearly. What I meant is that 
there are some arguments to DEFINE that are not part of asm-offsets.c, 
therefore they end up in the violation report, but are not actually 
relevant, because the macro DEFINE is actually what we want to exclude.
See for instance at the link below VCPU_TRAP_{NMI,MCE}, which are 
defined in asm/domain.h and used as arguments to DEFINE inside 
asm-offsets.c.
