To ensure the safety of this mitigation, the kernel must ensure that the
safe return sequence is itself free from attacker interference. In Zen3
and Zen4, this is accomplished by creating a BTB alias between the
untraining function srso_untrain_ret_alias() and the safe return
function srso_safe_ret_alias() which results in evicting a potentially
untraining function srso_alias_untrain_ret() and the safe return
function srso_alias_safe_ret() which results in evicting a potentially
poisoned BTB entry and using that safe one for all function returns.
In older Zen1 and Zen2, this is accomplished using a reinterpretation

description: |
The AD74412R and AD74413R are quad-channel software configurable input/output
solutions for building and process control applications. They contain
functionality for analog output, analog input, digital input, resistance
temperature detector, and thermocouple measurements integrated
into a single chip solution with an SPI interface.
The devices feature a 16-bit ADC and four configurable 13-bit DACs to provide
four configurable input/output channels and a suite of diagnostic functions.
The AD74413R differentiates itself from the AD74412R by being HART-compatible.
