When we disable a breakpoint through dr7, we unregister it right away, making us lose track of its corresponding address register value. It means that the following sequence would be unsupported: - set address in dr0 - enable it through dr7 - disable it through dr7 - enable it through dr7 because we lost the address register value when we disabled the breakpoint. Don't unregister the disabled breakpoints but rather disable them.

The introduction of the new 'DECLARE_EVENT_CLASS()' obviates the need for the 'TRACE_EVENT()' macro in some cases. Thus, docbook style comments that used to live with 'TRACE_EVENT()' are now moved to 'DEFINE_EVENT()'. Thus, we need to make the docbook system understand the new 'DEFINE_EVENT()' macro. In addition I've tried to futureproof the patch, by also adding support for 'DEFINE_SINGLE_EVENT()', since there has been discussion about renaming: TRACE_EVENT() -> DEFINE_SINGLE_EVENT(). Without this patch the tracepoint docbook fails to build. I've verified that this patch correctly builds the tracepoint docbook which currently covers signals, and irqs.

The backtick shell substitutions for PERL_EMBED_LDOPT/CCOPT make a lot of noise on stderr if Embed.pm isn't installed - this silences them.

To capture the relevant events for a given Perl script and to avoid having to continually remember and type in long command-lines, add a scripts/perl/bin directory containing two simple shell scripts for each Perl script, one for recording and one for processing/display. For example, to record perf data for the rw-by-pid.pl script, run scripts/perl/bin/rw-by-pid-record and to actually run the script and display the output run scripts/perl/bin/rw-by-pid-report.
