This is a merge of go/wvgerrit/22627 The call table was meant to be a long-term way to track the performance of all OEMCrypto function calls. This feature does not get used. Apps that call into the profiler can generate this from the history. This change was designed to go into Android O (go/wvgerrit/22503) but since the Call Table is causing problems on specific chip sets its being removed in NYC MR2.
