Some trace event formats print PFNs as hex while others print them as decimal. This is rather annoying when attempting to grep through traces to understand what's going on with a particular page. $ git grep -ho 'pfn=[0x%lu]\+' include/trace/events/ | sort | uniq -c 11 pfn=0x%lx 12 pfn=%lu 2 pfn=%lx Printing as hex is in the majority in the trace events, and all the normal printks in mm/ also print PFNs as hex, so change all the PFN formats in the trace events to use 0x%lx.
