[RFC,12/19] KVM: x86/mmu: Replace vcpu argument with kvm pointer in make_spte

Commit Message

Ben Gardon Nov. 10, 2021, 10:30 p.m. UTC

No that nothing in make_spte actually needs the vCPU argument, just
pass in a pointer to the struct kvm. This allows the function to be used
in situations where there is no relevant struct vcpu.

No functional change intended.
