The logging fast path seems still a bit slow to me. I would like
to have a logging macro that is not much worse than a stdio putc,
basically something like
get_cpu();
if (buffer space > N) {
memcpy(buffer, input, N);
buffer pointer += N;
} else {
FreeBuffer(input, N);
}
put_cpu();
This would need interrupt protection only if interrupts can access
it, best you use separate buffers for that too.
