Christopher Ferris 504d2cce64 Optimize code that only uses PageMap call. ... Some code only wants to use PageMap to determine whether pages are mapped in to memory. Modify the code to optimize this path. Changes: - Add a function that doesn't read all of usage stats data for every map. This operation is extremely expensive, and some code doesn't care about it. - Optimize the PageMap call to do a single read instead of a single read per page. - Add unit tests for these changes. Bug: 136245508 Test: Ran new unit tests. Test: Ran procrank and verified data looks good. Test: Ran DexDiag art tests. Change-Id: I37d03f2584551d26cb20be3abacdb958111d4eca		2019-07-12 16:28:09 -07:00
