Revision e7c25c441e9e0fa75b4c83e0b26306b702cfe90d authored by Peter Zijlstra on 14 August 2023, 11:44:34 UTC, committed by Borislav Petkov (AMD) on 16 August 2023, 19:58:59 UTC
Since there can only be one active return_thunk, there only needs be
one (matching) untrain_ret. It fundamentally doesn't make sense to
allow multiple untrain_ret at the same time.
Fold all the 3 different untrain methods into a single (temporary)
helper stub.
