2014-06-19	tools lib traceevent: Clean up format of args in cfg80211 plugin	Steven Rostedt
	While synchronizing what's in trace-cmd vs what's in perf, I came across a change that was made when entering the cfg80211 plugin into the tools/lib/traceevent directory. The function prototype went from: static unsigned long long process___le16_to_cpup(struct trace_seq s, unsigned long long args) to: static unsigned long long process___le16_to_cpup(struct trace_seq s, unsigned long long args) I can understand the line break after the long long, but there's no reason to keep args on a separate line.

2014-01-16	tools lib traceevent: Unregister handler when cfg80211 plugin is unloaded	Namhyung Kim
	The function handler should be unregistered when the plugin is unloaded otherwise it'll try to access invalid memory.

2014-01-15	tools lib traceevent: fix pointer-integer size mismatch	Mark Rutland
	The scsi and cfg80211 plugins cast between unsigned long long and pointers, which is problematic for architectures where unsigned long long is wider than the native pointer size: linux/tools/lib/traceevent/plugin_scsi.c: In function ‘process_scsi_trace_parse_cdb’: linux/tools/lib/traceevent/plugin_scsi.c:408:26: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] scsi_trace_parse_cdb(s, (unsigned char ) args[1], args[2]); linux/tools/lib/traceevent/plugin_cfg80211.c: In function ‘process___le16_to_cpup’: linux/tools/lib/traceevent/plugin_cfg80211.c:11:18: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] uint16_t val = (uint16_t *) args[0]; This patch adds an intermediate cast to unsigned long, silencing the warning.
