Subject: [PATCH] tracing: remove on the fly allocator from function profiler

Impact: safer code

The on the fly allocator for the function profiler was to save
memory. But at the expense of stability. Although it survived several
tests, allocating from the function tracer is just too risky, just
to save space.

This patch removes the allocator and simply allocates enough entries
at start up.

Each function gets a profiling structure of 40 bytes. With an average
of 20K functions, and this is for each CPU, we have 800K per online
CPU. This is not too bad, at least for non-embedded.
