Subject: [PATCH 01/30] perf tools: Fix a compiling error in trace-event-perl.c for 32 bits machine

From: Feng Tang <feng.tang@...el.com>

On my x86_32 mahcine, there is a compile error:

        CC util/scripting-engines/trace-event-perl.o
        cc1: warnings being treated as errors
        util/scripting-engines/trace-event-perl.c: In function
	perl_process_tracepoint:
        util/scripting-engines/trace-event-perl.c:285: error: format
	expects type 'int', but argument 2 has type '__u64'
        make: *** [util/scripting-engines/trace-event-perl.o] Error 1

Fix it by using the "%PRIu64" for __u64.

v2: use PRIu64 as suggested by Arnaldo.
