User visible:
- Rename the "colors.code" ~/.perfconfig variable to "colors.jump_arrows",
as it controls just the that UI element in the annotate browser (Taeung Song)
- Avoid trying to read ELF symtabs from device files, noticed while doing
memory profiling work (Jiri Olsa)
- Improve context detection when offering options in the hists browser,
i.e. some options don't make sense when the browser is not working with
a perf.data file ('perf top' mode), only in 'perf report' mode, like
scripting (Namhyung Kim)
Infrastructure:
- Elliminate duplication in the hists browser filter functions, getting the
common part into a function that receives callbacks for filtering by
DSO, thread, etc (Namhyung Kim)
- Fix misleadingly indented assignment, found using
gcc6 -Wmisleading-indentation (Markus Trippelsdorf)
- Handle LLVM relocation oddities in libbpf, introducing a 'perf test' that
detects such problems and then fixing the problem, so that the test now
passes (Wang Nan)
- More improvements to the build infrastructure to allow reusing the
feature detection facilities (Wang Nan)
- Auto initialize the globals needed by cpu__max_{cpu,node}() routines
(Arnaldo Carvalho de Melo)
Documentation:
- Document the perf sysctls in Documentation/sysctl/kernel.txt (Ben Hutchings)
- Document a bunch more ~/.perfconfig knobs (Taeung Song)
