    x86/bugs: Make Safe-RET robust against interrupt injection
    
    commit 7e7f81cf6f5ca3311e526308f55d7c54d3ba71f9 upstream.
    
    An attacker injecting interrupts while the Safe-RET mitigation executes
    on machines affected by SRSO can neutralize the safe return sequence,
    potentially leading to data leakage through speculative execution.
    
    Fixup register state as if the Safe-RET sequence executed successfully
    by "emulating" it, in a manner of speaking, and avoid executing a RET
    instruction after returning from the interrupt.
