Vincent DonnefortandSteven Rostedt (Google) 2e67fabd8b ring-buffer: Introduce ring-buffer remotes
Add ring-buffer remotes to support entities outside of the kernel (such
as firmware or a hypervisor) that writes events into a ring-buffer using
the tracefs format

Require a description of the ring-buffer pages (struct
trace_buffer_desc) and callbacks (swap_reader_page and reset) to set up
the ring-buffer on the kernel side.

Expect the remote entity to maintain and update the meta-page.
