Time to talk about how to get the whole thing merged.

I'm reasonably happy with the arch part of the patchset.  There are two
remaining issues in the arch part - cache flushing will not work as is on
a SMP system and the whole code patching is going to fail if the kernel
text is replicated with CONFIG_REPLICATE_KTEXT which is an IP27-only option.

I suggest we should go ahready and just disallow dynamic ftrace on on
these problematic configurations for now and deal with them later, so
something like


This leaves the non-arch bits to merge; patches which touch code outside
of arch/mips are:

    [PATCH v8 01/16] tracing: convert trace_clock_local() as weak function
    [PATCH v8 06/16] tracing: add an endian argument to
    [PATCH v8 07/16] tracing: add dynamic function tracer support for MIPS
    [PATCH v8 09/16] tracing: define a new __time_notrace annotation flag
    [PATCH v8 10/16] tracing: not trace the timecounter_read* in
