perf bpf: Add bpf.h to be used in eBPF proggies
So, the first helper is the one shortening a variable/function section attribute, from, for instance: char _license[] __attribute__((section("license"), used)) = "GPL"; to: char _license[] SEC("license") = "GPL"; Convert empty.c to that and it becomes: # cat ~acme/lib/examples/perf/bpf/empty.c #include <bpf.h> char _license[] SEC("license") = "GPL"; int _version SEC("version") = LINUX_VERSION_CODE; # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-zmeg52dlvy51rdlhyumfl5yf@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
