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.
