[RFC PATCH v1 15/30] KVM: arm64: COCCI: vgic3_cpu.cocci: reduce scope of vgic v3

Fuad Tabba tabba at google.com
Fri Sep 24 05:53:44 PDT 2021


vgic v3 interface functions are passed vcpu, when the state
that they need is the vgic interface, as well as the
kvm_cpu_context and the recently created vcpu_hyp_state. Reduce
the scope of its interface functions to these structs.

This applies the semantic patch with the following command:

spatch --sp-file cocci_refactor/vgic3_cpu.cocci arch/arm64/kvm/hyp/vgic-v3-sr.c --in-place
