[PATCH 2/8] KVM: PPC: Only WARN on invalid emulation

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

 



When we hit an emulation result that we didn't expect, that is an error,
but it's nothing that warrants a BUG(), because it can be guest triggered.

So instead, let's only WARN() the user that this happened.
