[PATCH] tracing: fix incorrect enabling of trace events by boot cmdline

There is a problem that trace events are not properly enabled with boot cmdline. Problem is that if we pass "trace_event=kmem:mm_page_alloc" to boot cmdline, it enables all kmem trace events. It is caused by parsing mechanism. When we parse cmdline, buffer contents is modified due to tokenization.
