Merge tag 'perf-core-for-mingo-4.20-20181025' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

- Introduce 'perf trace --max-events' for stopping 'perf trace' when
that many syscalls (enter+exit), tracepoints or other events such as
page faults take place.

Support that as well on a per-event basis, e.g.:

perf trace -e sched:*switch/nr=2/,block:*_plug/nr=4/,block:*_unplug/nr=1/,net:*dev_queue/nr=3,max-stack=16/

Will stop when 2 context switches, 4 block plugs, 1 block unplug and
3 net_dev_queue tracepoints take place. (Arnaldo Carvalho de Melo)

- Poll for monitored tasks being alive in 'perf stat -p/-t', exiting when
those tasks all terminate (Jiri Olsa)

- Encode -k clockid frequency into perf.data to enable timestamps derived
metrics conversion into wall clock time on reporting stage. (Alexey Budankov)

- Improve Intel PT call graph from SQL database and GUI python scripts,
including adopting the Qt MDI interface to allow for multiple subwindows
for all the tables, helping in better visualizing the data in the SQL
tables, also uses, when available, the Intel XED disassembler libraries
to present the Intel PT data as x86 asm mnemonics. This last feature
is not currently working in some cases, fix is being discussed (Adrian Hunter)

- Implement a ftrace function_graph view in 'perf script' when processing
hardware trace data such as Intel PT (Andi Kleen)

- Better integration with the Intel XED disassembler, when available, in
'perf script' (Andi Kleen)

- Some 'perf trace' drop refcount fixes (Arnaldo Carvalho de Melo)

- Add Sparc support to 'perf annotate', jitdump (David Miller)

- Fix PLT symbols entry/header sizes properly on Sparc (David Miller)

- Fix generation of system call table failure with /tmp mounted with 'noexec'
in arm64 (Hongxu Jia)

- Allow extended console debug output in 'perf script' (Milian Wolff)

- Flush output stream after events in 'perf script' verbose mode (Milian Wolff)
