Merge tag 'perf-urgent-for-mingo-4.19-20181017' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
- Stop falling back to kallsyms for vDSO symbols lookup, this wasn't
being really used and is not valid in arches such as Sparc, where
user and kernel space don't share the address space, relying only on
cpumode to figure out what DSOs to lookup (Arnaldo Carvalho de Melo)
- Align CPU map synthesized events properly, fixing SIGBUS in
CPUs like Sparc (David Miller)
- Fix use of alternatives to find JDIR (Jarod Wilson)
- Store IDs for events with their own CPUs when synthesizing user
level event details (scale, unit, etc) events, fixing a crash
when recording a PMU event with a cpumask defined (Jiri Olsa)
- Fix wrong filter_band* values for uncore Intel vendor events (Jiri Olsa)
- Fix detection of tracefs path in systems without tracefs, where
that path should be the debugfs mountpoint plus "/tracing/" (Jiri Olsa)
- Pass build flags to traceevent build, allowing using alternative
flags in distro packages, RPM, for instance (Jiri Olsa)
- Fix 'perf report' crash on invalid inline debug information (Milian Wolff)
- Synch KVM UAPI copies (Arnaldo Carvalho de Melo)
