From: Arnaldo Carvalho de Melo <a...@redhat.com> The commit 0c1fe6b:
'perf tools: Have the page size value available for all tools' Broke the python binding because the global variable 'page_size' is initialized on the main() routine, that is not called when using just the python binding, causing evlist.mmap() to fail because it expects that variable to be initialized to the system's page size. Fix it by initializing it on the binding init routine.
