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:

Pull perf tools updates from Arnaldo Carvalho de Melo:
"New features:

- Introduce controlling how 'perf stat' and 'perf record' works via a
control file descriptor, allowing starting with events configured
but disabled until commands are received via the control file
descriptor. This allows, for instance for tools such as Intel VTune
to make further use of perf as its Linux platform driver.

- Improve 'perf record' to to register in a perf.data file header the
clockid used to help later correlate things like syslog files and
perf events recorded.

- Add basic syscall and find_next_bit benchmarks to 'perf bench'.

- Allow using computed metrics in calculating other metrics. For
instance:

{
.metric_expr = "l2_rqsts.demand_data_rd_hit + l2_rqsts.pf_hit + l2_rqsts.rfo_hit",
.metric_name = "DCache_L2_All_Hits",
},
{
.metric_expr = "max(l2_rqsts.all_demand_data_rd - l2_rqsts.demand_data_rd_hit, 0) + l2_rqsts.pf_miss + l2_rqsts.rfo_miss",
.metric_name = "DCache_L2_All_Miss",
},
{
.metric_expr = "dcache_l2_all_hits + dcache_l2_all_miss",
.metric_name = "DCache_L2_All",
}

- Add suport for 'd_ratio', '>' and '<' operators to the expression
resolver used in calculating metrics in 'perf stat'.

Support for new kernel features:

- Support TEXT_POKE and KSYMBOL_TYPE_OOL perf metadata events to cope
with things like ftrace, trampolines, i.e. changes in the kernel
text that gets in the way of properly decoding Intel PT hardware
traces, for instance.

Intel PT:

- Add various knobs to reduce the volume of Intel PT traces by
reducing the level of details such as decoding just some types of
packets (e.g., FUP/TIP, PSB+), also filtering by time range.

- Add new itrace options (log flags to the 'd' option, error flags to
the 'e' one, etc), controlling how Intel PT is transformed into
perf events, document some missing options (e.g., how to synthesize
callchains).

BPF:

- Properly report BPF errors when parsing events.

- Do not setup side-band events if LIBBPF is not linked, fixing a
segfault.

Libraries:

- Improvements to the libtraceevent plugin mechanism.

- Improve libtracevent support for KVM trace events SVM exit reasons.

- Add a libtracevent plugins for decoding syscalls/sys_enter_futex
and for tlb_flush.

- Ensure sample_period is set libpfm4 events in 'perf test'.

- Fixup libperf namespacing, to make sure what is in libperf has the
perf_ namespace while what is now only in tools/perf/ doesn't use
that prefix.

Arch specific:

- Improve the testing of vendor events and metrics in 'perf test'.

- Allow no ARM CoreSight hardware tracer sink to be specified on
command line.

- Fix arm_spe_x recording when mixed with other perf events.

- Add s390 idle functions 'psw_idle' and 'psw_idle_exit' to list of
idle symbols.

- List kernel supplied event aliases for arm64 in 'perf list'.

- Add support for extended register capability in PowerPC 9 and 10.

- Added nest IMC power9 metric events.

Miscellaneous:

- No need to setup sample_regs_intr/sample_regs_user for dummy
events.

- Update various copies of kernel headers, some causing perf to
handle new syscalls, MSRs, etc.

- Improve usage of flex and yacc, enabling warnings and addressing
the fallout.

- Add missing '--output' option to 'perf kmem' so that it can pass it
along to 'perf record'.

- 'perf probe' fixes related to adding multiple probes on the same
address for the same event.

- Make 'perf probe' warn if the target function is a GNU indirect
function.

- Remove //anon mmap events from 'perf inject jit' to fix supporting
both using ELF files for generated functions and the perf-PID.map
approaches"

tools/: replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
