      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.

[ Add include linux/stddef.h before perf_events.h for systems where __always_inline isn't pulled in before used, such as older Alpine Linux ]

      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.
