A few more fixes for ftrace infrastructure.
...
I was cleaning out my INBOX and found two fixes from zhangwei from
a year ago that were lost in my mail. These fix an inconsistency between
trace_puts() and the way trace_printk() works. The reason this is
important to fix is because when trace_printk() doesn't have any
arguments, it turns into a trace_puts(). Not being able to enable a
stack trace against trace_printk() because it does not have any arguments
is quite confusing. Also, the fix is rather trivial and low risk.
While porting some changes to PowerPC I discovered that it still has
the function graph tracer filter bug that if you also enable stack tracing
the function graph tracer filter is ignored. I fixed that up.
Finally, Martin Lau, fixed a bug that would cause readers of the
ftrace ring buffer to block forever even though it was suppose to be
NONBLOCK.

This also includes the fix from an earlier pull request:
"Oleg Nesterov fixed a memory leak that happens if a user creates a
tracing instance, sets up a filter in an event, and then removes that
instance. The filter allocates memory that is never freed when the
instance is destroyed"
