Alexandre Chartre d16e0b2667 x86/entry: Remove UNTRAIN_RET from native_irq_return_ldt ... UNTRAIN_RET is not needed in native_irq_return_ldt because RET untraining has already been done at this point. In addition, when the RETBleed mitigation is IBPB, UNTRAIN_RET clobbers several registers (AX, CX, DX) so here it trashes user values which are in these registers.
