- Fix the dwarf regs table for x86_64, adding a missing % to the "%di"
register, noticed with a failing 'perf test bpf' (Arnaldo Carvalho de Melo)
- Fix handling of mmap parameters in the 'perf trace' beautifier in
architectures that don't have the same mappings as x86_64 (Wang Nan)
- Handle hugetbl mappings in older systems running new kernels (Wang Nan)
- Resolve 'call' operands in 'annotate', that when using /proc/kcore
were appearing just as hexadecimal addresses, to function names
(Arnaldo Carvalho de Melo)
- Fix width computation for srcline sort entry (Jiri Olsa)
- Do not ignore call instruction with indirect target in 'annotate'
(Ravi Bangoria)
- Handle MADV_FREE in the madvise 'trace' beautifier (Wang Nan)
- Fix build of 'perf trace' mman beautifier in !x86_64 (Wang Nan)
Infrastructure changes:
- Add infrastructure for PMU specific configuration, allowing to pass
config variables directly to the kernel PMU driver, prefixing those
variables with a '@', part of a larger series to support Coresight (Mathieu Poirier)
