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
* fix compilation error that the RISC-V merge introduced in selftests

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm updates from Paolo Bonzini:
"The bulk of the changes here is a largish change to guest_memfd,
delaying the clearing and encryption of guest-private pages until they
are actually added to guest page tables. This started as "let's make
it impossible to misuse the API" for SEV-SNP; but then it ballooned a
bit.
The new logic is generally simpler and more ready for hugepage support
in guest_memfd.
Summary:
- 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
- fix compilation error that the RISC-V merge introduced in selftests"
