pm-graph v5.7 - important s2idle fixes
Important fixes: - in s2idle, use timekeeping_freeze trace mark instead of machine_suspend to denote entry into s2idle mode. - in s2idle, use machine_suspend trace mark to create a new virtual device called "s2idle_enter_<n>x". It denotes an s2idle_enter call loop of <n> iterations where s2idle was never actually achieved. It isn't counted as "freeze time" in the header. - in s2idle, only show multiple freeze times if s2idle went in and out of resume_noirq. Otherwise multiple freezes are shown with "waking" time subtracted (waking time is time spent outside s2idle dealing with wakeups). - in s2idle summaries, include "FREEZEWAKE" as an issue when at least 1ms is spent waking from s2idle. A clean run should only wake for the rtc timer. - add support for device callbacks with matching names in the same phase. In rare cases some devices register multiple callbacks from separate drivers using the same name. Without this fix only one is shown. - add kparamsfmt string back to fix bootgraph General updates: - when suspend_machine is missing, error says "failed in suspend_machine" - extract target count/time and add to summary title if -multi used - include any instances of "timeout" in dmesg as issues to be logged. - fix ftrace parse to handle any number of flags (instead of just 4). - remove sync/async_device string from device detail, remains in hover. - when using callgraph (-f) add driver name to callgraph titles.
