You seem to have either randomly chosen just 3 patches from Lina/Ulf's CPU genpd series or this series doesn't entirely depend on it ?
If latter, how does this work with PSCI CPU_SUSPEND operations ?
And why this can be part of PSCI firmware implementation. Only PSCI firmware needs if RPMH votes need to be flushed or not. So, honestly I don't see the need for this in Linux.
