Description of the change
+ * Count the number of CPUs and divide buffer_size_kb by the number of CPUs.
+ Users should watch for instances of "mmiotrace has lost events" in dmesg to make
+ sure the trace buffers are not too small. The original value for
+ buffer_size_kb was chosen somewhat arbitrarily. Empirical testing
+ has shown that its large enough, so we don't actually know where the lower
+ boundary lies.
+ -LP: #491943
