Arnaldo Carvalho de Melo 0ac25fd0a0 perf tools: Remove perf.h from source files not needing it 
With the movement of lots of stuff out of perf.h to other headers we
ended up not needing it in lots of places, remove it from those places.

README

Perf-Trace-Util version 0.01

This module contains utility functions for use with perf script.

Core.pm and Util.pm are pure Perl modules; Core.pm contains routines that the core perf support for Perl calls on and should always be 'used', while Util.pm contains useful but optional utility functions that scripts may want to use. Context.pm contains the Perl->C interface that allows scripts to access data in the embedding perf executable; scripts wishing to do that should 'use Context.pm'.

The Perl->C perf interface is completely driven by Context.xs. If you want to add new Perl functions that end up accessing C data in the perf executable, you add desciptions of the new functions here. scripting_context is a pointer to the perf data in the perf executable that you want to access - it's passed as the second parameter, $context, to all handler functions.

After you do that:

perl Makefile.PL # to create a Makefile for the next step make # to create Context.c

edit Context.c to add const to the char* file = FILE line in XS(boot_Perf__Trace__Context) to silence a warning/error.

You can delete the Makefile, object files and anything else that was generated e.g. blib and shared library, etc, except for of course Context.c

You should then be able to run the normal perf make as usual.

INSTALLATION

Building perf with perf script Perl scripting should install this module in the right place.

You should make sure libperl and ExtUtils/Embed.pm are installed first e.g. apt-get install libperl-dev or yum install perl-ExtUtils-Embed.
