[PATH stable 5.15,5.10 3/4] irqchip/gic-v3: Always trust the managed affinity provided by the core code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Marc Zyngier <maz@xxxxxxxxxx>

commit 3f893a5962d31c0164efdbf6174ed0784f1d7603 upstream.

Now that the core code has been fixed to always give us an affinity
that only includes online CPUs, directly use this affinity when
computing a target CPU.
