Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
perf report:
He Kuang:
- Don't shadow inlined symbol with different addr range.
perf script:
Jiri Olsa:
- Allow +- operator to ask for -F to add/remove fields to
the default set, for instance to ask for the removal of the
'cpu' field in tracepoint events, adding 'period' to that
kind of events, etc.
perf test:
Thomas Richter:
- Fix scheduler tracepoint signedness of COMM fields failure of
'evsel-tp-sched' test on s390 and other arches.
Tommi Rantala:
- Skip trace+probe_vfs_getname.sh when 'perf trace' is not built.
perf trace:
Arnaldo Carvalho de Melo:
- Add initial BPF map dumper, initially just for the current, minimal
needs of the augmented_raw_syscalls BPF example used to collect
pointer args payloads that uses BPF maps for pid and syscall filtering,
but will in time have features similar to 'perf stat' --interval-print,
--interval-clear, ways to signal from a BPF event that a specific
map (or range of that map) should be printed, optionally as a
histogram, etc.
General:
Jiri Olsa:
- Add CPU and NUMA topologies classes for further reuse, fixing some
issues in the process.
- Fixup some warnings and debug levels.
- Make rm_rf() remove single file, not just directories.
Documentation:
Jonas Rabenstein:
- Fix HEADER_CMDLINE description in perf.data documentation.
- Fix documentation of the Flags section in perf.data.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
