* Documentation: KVM: add separate directories for architecture-specific ↵Paolo Bonzini2022-03-291-192/+0
| | | | | | | | | | | | | | | | documentation ARM already has an arm/ subdirectory, but s390 and x86 do not even though they have a relatively large number of files specific to them. Create new directories in Documentation/virt/kvm for these two architectures as well. While at it, group the API documentation and the developer documentation in the table of contents.

* KVM: X86: Introduce KVM_HC_MAP_GPA_RANGE hypercallAshish Kalra2021-06-171-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This hypercall is used by the SEV guest to notify a change in the page encryption status to the hypervisor. The hypercall should be invoked only when the encryption attribute is changed from encrypted -> decrypted and vice versa. By default all guest pages are considered encrypted. The hypercall exits to userspace to manage the guest shared regions and integrate with the userspace VMM's migration code.
