Wang Nan ba92732e98 perf kmaps: Check kmaps to make code more robust ... This patch add checks in places where map__kmap is used to get kmaps from struct kmap. Error messages are added at map__kmap to warn invalid accessing of kmap (for the case of !map->dso->kernel, kmap(map) does not exists at all). Also, introduces map__kmaps() to warn uninitialized kmaps.
