Linus Torvalds 05ff1d355e ftrace: Store the order of pages allocated in ftrace_page
[ Upstream commit db42523b4f ]

Instead of saving the size of the records field of the ftrace_page, store
the order it uses to allocate the pages, as that is what is needed to know
in order to free the pages. This simplifies the code.
