perf trace:

Arnaldo Carvalho de Melo:

- Use BPF_MAP_TYPE_PROG_ARRAY + bpf_tail_call() for augmenting raw syscalls,
i.e. copy pointers passed to/from userspace. The use of a table per syscall
to tell the BPF program what to copy made the raw_syscalls:sys_enter/exit
programs a bit complex, the scratch space would have to be bigger to allow
for checking all args to see which ones were a pathname, so use a PROG_ARRAY
map instead, test it with syscalls that receive multiple pathnames at
different registers (rename, renameat, etc).

- Beautify various syscalls using this new infrastructure, and also add code
that looks for syscalls with BPF augmenters, such as "open", and then reuse
it with syscalls not yet having a specific augmenter, but that copies the
same argument with the same type, say "statfs" can initially reuse "open",
beautifier, as both have as its first arg a "const char *".

- Do not using fd->pathname beautifier when the 'close' syscall isn't enabled,
as we can't invalidate that mapping.

core:

Jiri Olsa:

- Introduce tools/perf/lib/, that eventually will move to tools/lib/perf/, to
allow other tools to use the abstractions and code perf uses to set up
the perf ring buffer and set up the many possible combinations in allowed
by the kernel, starting with 'struct perf_evsel' and 'struct perf_evlist'.

perf vendor events:

Michael Petlan:

- Add missing event description to power9 event definitions.
