KVM: x86/mmu: Export kvm_tdp_map_page()

bonzini · bonzini · commit 4fa609cb8217 · 2025-07-15T19:12:42.000+02:00
JIRA: https://issues.redhat.com/browse/RHEL-15711 Upstream status: https://git.kernel.org/pub/scm/virt/kvm/kvm.git In future changes coco specific code will need to call kvm_tdp_map_page() from within their respective gmem_post_populate() callbacks. Export it so this can be done from vendor specific code. Since kvm_mmu_reload() will be needed for this operation, export its callee kvm_mmu_load() as well.
