Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf fixes from Thomas Gleixner:
 "The perf update contains the following bits:

  x86:
   - Prevent setting freeze_on_smi on PerfMon V1 CPUs to avoid #GP

  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)"
