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

Pull perf fixes from Ingo Molnar:
 "Various fixes.

  The -g perf report lockup you reported is only partially addressed,
  patches that fix the excessive runtime are still being worked on"

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  perf/x86: Fix uncore PCI fixed counter handling
  uprobes: Fix utask->depth accounting in handle_trampoline()
  perf/x86: Add constraint for IVB CYCLE_ACTIVITY:CYCLES_LDM_PENDING
  perf: Fix up MMAP2 buffer space reservation
  perf tools: Add attr->mmap2 support
  perf kvm: Fix sample_type manipulation
  perf evlist: Fix id pos in perf_evlist__open()
  perf trace: Handle perf.data files with no tracepoints
  perf session: Separate progress bar update when processing events
  perf trace: Check if MAP_32BIT is defined
  perf hists: Fix formatting of long symbol names
  perf evlist: Fix parsing with no sample_id_all bit set
  perf tools: Add test for parsing with no sample_id_all bit
  perf trace: Check control+C more often
