As it is going away from util.h, where it is not needed. This is mostly for things like MAXPATHLEN, MAX() and MIN(), these later two probably should go away in favor of its kernel sources replacements.

Currently 'perf c2c report' determines display mode using the --stdio option, but it could be a problem if stdout is not a tty since setup_browser falls back to stdio in this case. But perf c2c didn't know this and tried to use TUI browser anyway. It should check "use_browser" variable instead. For example, the following command showed nothing and broke terminal setting. Now it's fixed.. $ perf c2c report | head ================================================= Trace Event Information ================================================= Total records : 136 Locked Load/Store Operations : 6 Load Operations : 62 Loads - uncacheable : 0 Loads - IO : 1 Loads - Miss : 7 Loads - no mapping : 2 Committer notes: When trying it without a proper perf.data file it results in a stuck terminal, just as Namhyung reported above: [acme@jouet ~]$ perf c2c report | head WARNING: no sample cpu value[acme@jouet ~]$ One has to kill it from some other xterm.

Currently we display the cacheline list sorted on remote HITMs by default. The problem is that they might not be always counted and 'perf c2c report' displays an empty output. Thus it's more convenient to display and sort the cacheline list based on the total of HITMs and have the best change to see data in the default report run.
