[PATCH v3 3/6] KVM: arm64: Remove unused __sve_save_state

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

 



Now that we don't have any users left for __sve_save_state, remove
it altogether. Should we ever need to save the SVE state from the
hypervisor again, we can always re-introduce it.
