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"

perf trace beauty: Use the autogenerated protocol family table

That helps us not to lose new protocol families when they are
introduced, replacing that hardcoded, dated family->string table.

To recap what this allows us to do:

# perf trace -e syscalls:sys_enter_socket/max-stack=10/ --filter=family==INET --max-events=1
0.000 fetchmail/41097 syscalls:sys_enter_socket(family: INET, type: DGRAM|CLOEXEC|NONBLOCK, protocol: IP)
__GI___socket (inlined)
reopen (/usr/lib64/libresolv-2.31.so)
send_dg (/usr/lib64/libresolv-2.31.so)
__res_context_send (/usr/lib64/libresolv-2.31.so)
__GI___res_context_query (inlined)
__GI___res_context_search (inlined)
_nss_dns_gethostbyname4_r (/usr/lib64/libnss_dns-2.31.so)
gaih_inet.constprop.0 (/usr/lib64/libc-2.31.so)
__GI_getaddrinfo (inlined)
[0x15cb2] (/usr/bin/fetchmail)
#

More work is still needed to allow for the more natura strace-like
syscall name usage instead of the trace event name:

# perf trace -e socket/max-stack=10,family==INET/ --max-events=1

I.e. to allow for modifiers to follow the syscall name and for logical
expressions to be accepted as filters to use with that syscall, be it as
trace event filters or BPF based ones.

Using -v we can see how the trace event filter is built:

# perf trace -v -e syscalls:sys_enter_socket/call-graph=dwarf/ --filter=family==INET --max-events=2
<SNIP>
New filter for syscalls:sys_enter_socket: (family==0x2) && (common_pid != 41384 && common_pid != 2836)
<SNIP>

$ tools/perf/trace/beauty/socket.sh | grep -w 2
[2] = "INET",

perf beauty sockaddr: Fix augmented syscall format warning

The sockaddr related examples given in
`tools/perf/examples/bpf/augmented_syscalls.c` almost always use `long`s
to represent most of their fields.

However, `size_t syscall_arg__scnprintf_sockaddr(..)` has a `scnprintf`
call that uses `"%#x"` as format string.

This throws a warning (whenever the syscall argument is `unsigned
long`).

Added `l` identifier to indicate that the `arg->value` is an unsigned
long.

Not sure about the complications of this with x86 though.
