[v3,1/4] Revert some patches from recent [PATCH v6] "Fixing record/replay and adding reverse debugging"

Commit Message

Artem Pisarenko Oct. 18, 2018, 11:04 a.m. UTC

That patch series introduced new virtual clock type for use in external subsystems. It breaks desired behavior in non-record/replay usage scenarios.

This reverts commit 87f4fe7653baf55b5c2f2753fe6003f473c07342.
This reverts commit 775a412bf83f6bc0c5c02091ee06cf649b34c593.
This reverts commit 9888091404a702d7ec79d51b088d994b9fc121bd.
