Merge tag 'perf-tools-fixes-2020-07-07' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tooling fixes from Arnaldo Carvalho de Melo:
- Intel PT fixes for PEBS-via-PT with registers
- Fixes for Intel PT python based GUI
- Avoid duplicated sideband events with Intel PT in system wide tracing
- Remove needless 'dummy' event from TUI menu, used when synthesizing
meta data events for pre-existing processes
- Fix corner case segfault when pressing enter in a screen without
entries in the TUI for report/top
- Fixes for time stamp handling in libtraceevent
- Explicitly set utf-8 encoding in perf flamegraph
- Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy',
silencing perf build warning
