It seems this patch adds non-dynamic ftrace, this code should not
appear here.
BTW is it really necessary for non-dynamic ftrace? I do not use it
directly and frequently, IMHO, non-dynamic can be completely
replaced dynamic?
Note, I keep the non dynamic ftrace around for debugging purposes.
But sure, it's pretty useless. It's also good for bringing ftrace to a new
architecture (like this patch is doing), as it is easier to implement than
dynamic ftrace, and getting the non-dynamic working is usually the first
step in getting dynamic ftrace working.
But it's really up to the arch maintainers to keep it or not.
Before submitting, I saw that other architectures almost kept
non-dynamic methods without cleaning up, I tend to keep them.
How do you think, Huacai. :)
