Subject: [PATCH 3/9] KVM: SVM: Pass @vcpu to exit handlers (and many, many
other places)
Refactor the svm_exit_handlers API to pass @vcpu instead of @svm to
allow directly invoking common x86 exit handlers (in a future patch).
Opportunistically convert an asburd number of instances of 'svm->vcpu'
to direct uses of 'vcpu' to avoid pointless casting.
No functional change intended.
