  perf stat: Fix duplicate PMU name for interval print (2018-04-24 16:12:00 -0300)

----------------------------------------------------------------
perf/urgent fixes:

perf stat:

- Keep the '/' event modifier separator in fallback, for example when
  fallbacking from 'cpu/cpu-cycles/' to user level only, where it should
  become 'cpu/cpu-cycles/u' and not 'cpu/cpu-cycles/:u' (Jiri Olsa)

- Fix PMU events parsing rule, improving error reporting for
  invalid events (Jiri Olsa)

- Disable write_backward and other event attributes for !group
  events in a group, fixing, for instance this group: '{cycles,msr/aperf/}:S'
  that has leader sampling (:S) and where just the 'cycles',
  the leader event, should have the write_backward attribute
  set, in this case it all fails because the PMU where 'msr/aperf/'
  lives doesn't accepts write_backward style sampling (Jiri Olsa)

- Only fall back group read for leader (Kan Liang)

- Fix core PMU alias list for X86 platform (Kan Liang)

- Print out hint for mixed PMU group error (Kan Liang)

- Fix duplicate PMU name for interval print (Kan Liang)

Core:

- Set main kernel end address properly when reading kernel and
  module maps (Namhyung Kim)

perf mem:

- Fix incorrect entries and add missing man options (Sangwon Hong)

s/390:

- Remove s390 specific strcmp_cpuid_cmp function (Thomas Richter)

- Adapt 'perf test' case record+probe_libc_inet_pton.sh for s390

- Fix s390 undefined record__auxtrace_init() return value in
  'perf record' (Thomas Richter)

Test results:

The first ones are container (docker) based builds of tools/perf with
and without libelf support.  Where clang is available, it is also used
to build perf with/without libelf, and building with LIBCLANGLLVM=1
(built-in clang) with gcc and clang when clang and its devel libraries
are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
