2012-09-28	tools: Fix pthread flag for Makefile of trace-agent used by virtio-trace	Yoshihiro YUNOMAE
	pthread flag should not be -lpthread but -pthread using gcc. The -lpthread links the external multithread library. On the other hand, the -pthread manages both the gcc's preprocessor and linker to be able to compile with pthread.

2012-09-28	tools: Add guest trace agent as a user tool	Yoshihiro YUNOMAE
	This patch adds a user tool, "trace agent" for sending trace data of a guest to a Host in low overhead. This agent has the following functions: - splice a page of ring-buffer to read_pipe without memory copying - splice the page from write_pipe to virtio-console without memory copying - write trace data to stdout by using -o option - controlled by start/stop orders from a Host Changes in v2: - Cleanup (change fprintf() to pr_err() and an include guard) Signed-off-by: Yoshihiro YUNOMAE <yoshihiro.yunomae.ez@hitachi.com> Acked-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
