      genelf: Use HAVE_LIBCRYPTO_SUPPORT, not the never defined HAVE_LIBCRYPTO · 91cea6be
      Arnaldo Carvalho de Melo authored 
      When genelf was introduced it tested for HAVE_LIBCRYPTO not
HAVE_LIBCRYPTO_SUPPORT, which is the define the feature test for openssl
defines, fix it.

This also adds disables the deprecation warning, someone has to fix this
to build with openssl 3.0 before the warning becomes a hard error.

Fixes: 9b07e27f ("perf inject: Add jitdump mmap injection support")

      perf build: Suppress openssl v3 deprecation warnings in libcrypto feature test · 10fef869
      Zixuan Tan authored 
      With OpenSSL v3 installed, the libcrypto feature check fails as it use the
deprecated MD5_* API (and is compiled with -Werror). The error message is
as follows.

$ make tools/perf
```
Makefile.config:778: No libcrypto.h found, disables jitted code injection,
please install openssl-devel or libssl-dev

```

This is very confusing because the suggested library (on my Ubuntu 20.04
it is libssl-dev) is already installed. As the test only checks for the
presence of libcrypto, this commit suppresses the deprecation warning to
allow the test to pass.

      perf parse-events: Break out tracepoint and printing · 9b7c7728
      Ian Rogers authored 
      Move print_*_events functions out of parse-events.c into a new
print-events.c. Move tracepoint code into tracepoint.c or
trace-event-info.c (sole user). This reduces the dependencies of
parse-events.c and makes it more amenable to being a library in the
future.

Remove some unnecessary definitions from parse-events.h. Fix a
checkpatch.pl warning on using unsigned rather than unsigned int.  Fix
some line length warnings too.

      perf parse-events: Don't #define YY_EXTRA_TYPE · 32f457ab
      Ian Rogers authored 
      Adding a #define to side-effect a local include isn't clean, for
example, it inhibits header precompilation. YY_EXTRA_TYPE is
defined to be void* by default, so just remove.
