ftrace: convert single large buffer into single pages.
Allocating large buffers for the tracer may fail easily.
This patch converts the buffer from a large ordered allocation
to single pages. It uses the struct page LRU field to link the
pages together.
Later patches may also implement dynamic increasing and decreasing
of the trace buffers.
