Merge branch 'kvm-fixes' into HEAD
* fix latent bug in how usage of large pages is determined for confidential VMs * fix "underline too short" in docs * eliminate log spam from limited APIC timer periods * disallow pre-faulting of memory before SEV-SNP VMs are initialized * delay clearing and encrypting private memory until it is added to guest page tables * this change also enables another small cleanup: the checks in SNP_LAUNCH_UPDATE that limit it to non-populated, private pages can now be moved in the common kvm_gmem_populate() function
