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
