Pull more perf tools updates from Arnaldo Carvalho de Melo:
 "Fixes:
   - Fixes for 'perf bench numa'.

   - Always memset source before memcpy in 'perf bench mem'.

   - Quote CC and CXX for their arguments to fix build in environments
     using those variables to pass more than just the compiler names.

   - Fix module symbol processing, addressing regression detected via
     "perf test".

   - Allow multiple probes in record+script_probe_vfs_getname.sh 'perf
     test' entry.

  Improvements:
   - Add script to autogenerate socket family name id->string table from
     copy of kernel header, used so far in 'perf trace'.

   - 'perf ftrace' improvements to provide similar options for this
     utility so that one can go from 'perf record', 'perf trace', etc to
     'perf ftrace' just by changing the name of the subcommand.

   - Prefer new "sched:sched_waking" trace event when it exists in 'perf
     sched' post processing.

   - Update POWER9 metrics to utilize other metrics.

   - Fall back to querying debuginfod if debuginfo not found locally.

  Miscellaneous:
   - Sync various kvm headers with kernel sources"

tools headers UAPI: Sync kvm.h headers with the kernel sources

2020-08-12T12:02:40+00:00

To pick the changes in:

  3edd68399dc1 ("KVM: x86: Add a capability for GUEST_MAXPHYADDR < HOST_MAXPHYADDR support")
  1aa561b1a4c0 ("kvm: x86: Add "last CPU" to some KVM_EXIT information")
  23a60f834406 ("s390/kvm: diagnose 0x318 sync and reset")

That do not result in any change in tooling, as the additions are not
being used in any table generator.

This silences these perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'

To get the changes in:

This doesn't result in any changes in tooling, no new ioctls to be

tools/bpf: Support new uapi for map element bpf iterator

2020-08-06T23:39:14+00:00

Previous commit adjusted kernel uapi for map
element bpf iterator. This patch adjusted libbpf API
due to uapi change. bpftool and bpf_iter selftests
are also changed accordingly.

tools headers API: Update close_range affected files

2020-08-06T12:52:41+00:00

To pick the changes from:

  55db9c0e8534 ("net: remove compat_sys_{get,set}sockopt")
  9b4feb630e8e ("arch: wire-up close_range()")

That automagically add the 'close_range' syscall to tools such as 'perf
trace'.

Before:

  # perf trace -e close_range
  event syntax error: 'close_range'
                       \___ parser error
  Run 'perf list' for a list of valid events

   Usage: perf trace [] []
      or: perf trace [] --  []
      or: perf trace record [] []
      or: perf trace record [] --  []

      -e, --event    event/syscall selector. use 'perf list' to list available events
  #

After, system wide strace like tracing for this syscall:

  # perf trace -e close_range
  ^C#

No calls, I need some test proggie :-)
