This is about some (rare) cases where userspace QEMU in a KVM setup determines that it needs to deliver an exception to the guest, and does that by adjusting the CPU state appropriately (changing PC, PSTATE, ESR_EL1, etc etc) before telling KVM to KVM_RUN again. Currently we only need that for some places where we're doing debugging of the guest, but there is that pending patchset that would also like to do it in case of a detected hardware memory error. (Most of the time when the guest takes an exception it's because the host kernel/KVM have determined that it's necessary and done the relevant messing with the guest CPU state.) thanks -- PMM
