Joonsoo Kim 84fce9db4d tracing: Fix incorrect enabling of trace events by boot cmdline ... There is a problem that trace events are not properly enabled with boot cmdline. The problem is that if we pass "trace_event=kmem:mm_page_alloc" to the boot cmdline, it enables all kmem trace events, and not just the page_alloc event. This is caused by the parsing mechanism. When we parse the cmdline, the buffer contents is modified due to tokenization. And, if we use this buffer again, we will get the wrong result. Unfortunately, this buffer is be accessed three times to set trace events properly at boot time. So, we need to handle this situation. There is already code handling ",", but we need another for ":". This patch adds it.
