perf tools: Handle PERF_RECORD_KSYMBOL
This patch handles PERF_RECORD_KSYMBOL in perf record/report. Specifically, map and symbol are created for ksymbol register, and removed for ksymbol unregister. This patch also sets perf_event_attr.ksymbol properly. The flag is ON by default. Committer notes: Use proper inttypes.h for u64, fixing the build in some environments like in the android NDK r15c targetting ARM 32-bit. I.e. fixing this build error: util/event.c: In function 'perf_event__fprintf_ksymbol': util/event.c:1489:10: error: format '%lx' expects argument of type 'long unsigned int', but argument 3 has type 'u64' [-Werror=format=] event->ksymbol_event.flags, event->ksymbol_event.name); ^ cc1: all warnings being treated as errors Signed-off-by: Song Liu <songliubraving@fb.com> Reviewed-by: Arnaldo Carvalho de Melo <acme@redhat.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexei Starovoitov <ast@kernel.org> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: Peter Zijlstra <peterz@infradead.org> Cc: kernel-team@fb.com Cc: netdev@vger.kernel.org Link: http://lkml.kernel.org/r/20190117161521.1341602-6-songliubraving@fb.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
