312 bytes for a couple more symbols is too much to be justified from kallsyms alone.
In a 64 bit machine each new symbol should take about 8 bytes for the address + ~ half the size of the symbol name, which in this case would give at most about ~50 bytes.
I guess the rest should come from the extra EXPORT_SYMBOL's...
