Merge tag 'perf-urgent-for-mingo-4.17-20180425' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

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)
