Provide a trace mechanism for debugging Haswell/Broadwell specific SST IPC messages.

Applied, thanks.

• TP_STRUCT__entry(

• __field(	unsigned int,	status		)
  

• __field(	unsigned int,	mask		)
  

• ),
• TP_fast_assign(

• __entry->status = status;
  

• __entry->mask = mask;
  

• ),
• TP_printk("status 0x%8.8x mask 0x%8.8x",

• (unsigned int)__entry->status, (unsigned int)__entry->mask)
  

I found out the other day that the trace infrastructure has a neat helper called __print_symbolic which can decode things - might be helpful for some of these, though I don't think it does bitfields it might help with making the IPC messages more legible.
