tools subcmd: Add missing NORETURN define for parse-options.h

2016-01-12T15:42:07Z

parse-options.h uses the NORETURN macro without defining it. perf doesn't see a build error because it defines the macro in util.h before including parse-options.h. But any other tool including it will see an error. Define the macro in parse-options.h (if not already defined) so that other tools can include it. Signed-off-by: Josh Poimboeuf Cc: "H.

perf bpf: Fix build breakage due to libbpf

2016-01-11T22:22:21Z

perf build is currently (v4.4-rc5) broken on powerpc: bpf.c:28:4: error: #error __NR_bpf not defined. libbpf does not support your arch. # error __NR_bpf not defined. libbpf does not support your arch. ^ Fix this by including tools/scripts/Makefile.arch for the proper $ARCH macro. While at it, remove redundant LP64 macro definition. Also, since libbpf require $(srctree) now, detect the path of srctree like perf. Signed-off-by: Naveen N.

tools lib: Move find_next_bit.c to tools/lib/

2016-01-08T15:35:35Z

The commit that introduced it should've moved it to the same place, plus the 'tools/' prefix, but instead moved it to a bogus tools/lib/util/ directory, being the only file there. Move it to tools/lib/find_bit.c, picking the name for the file where these routines live since: 8f6f19dd5143 ("lib: move find_last_bit to lib/find_next_bit.c") Next step is to make tools/lib/find_bit.c to differ from lib/find_bit.c just in removing what is not used by tools/.
