This mostly would have broken gamepad tick support on non-samd ports. The "ms32" and "ms64" variants of the tick functions are introduced because there is no 64-bit atomic read. Disabling interrupts avoids a low probability bug where milliseconds could be off by ~49.5 days once every ~49.5 days (2^32 ms). Avoiding disabling interrupts when only the low 32 bits are needed is a minor optimization. Testing performed: on metro m4 express, USB still works and time.monotonic_ns() still counts up 2019-11-12T16:26:14+00:00 Hierophect hierophect@gmail.com 2019-11-12T16:26:14+00:00 urn:sha1:bbc366b85b3a29834def291805ca24c593f12915 2019-10-21T21:06:40+00:00 Hierophect hierophect@gmail.com 2019-10-21T20:24:32+00:00 urn:sha1:a596213526cdfba0688fbe8228f49c798f1b7d1e 2019-09-17T19:45:15+00:00 Hierophect hierophect@gmail.com 2019-09-17T19:45:15+00:00 urn:sha1:7c713b9e3b57ac9bf85dd755022d763385203b54 2019-07-24T20:31:25+00:00 Hierophect hierophect@gmail.com 2019-07-24T20:31:25+00:00 urn:sha1:295afaaf6c91a32c7e7a53338a4cb4ac08c555e0 2019-07-09T17:03:22+00:00 Hierophect hierophect@gmail.com 2019-07-09T17:03:22+00:00 urn:sha1:7742a97c22eb295c4850ba279ee68dd156eecc4b 2019-07-01T23:47:10+00:00 Hierophect hierophect@gmail.com 2019-07-01T23:47:10+00:00 urn:sha1:040acc3a3228c4204d8154656a1249171b68c75a 2019-06-28T20:34:27+00:00 Hierophect hierophect@gmail.com 2019-06-28T20:34:27+00:00 urn:sha1:b93f93f17404330d3bfbcb52923eec0521845157
