Hi Paolo, here is v4 of the groundwork patches for the upcoming SEV-ES support in the Linux kernel. They are part of both the client patch-set and the KVM hypervisor patches (under development). Patch 1 necessary to fix a compile warning about a stack-frame getting too large. Patches 2 and 3 define the Guest Hypervisor Communication Block (GHCB) and accessor functions and the last patch is a cleanup. This version addresses more review comments from Sean. Additionally the patches are now checkpatch-clean. It would be great if you could consider them for v5.9, so that the client and the hypervisor patch-sets can be developed more independently of each other. Please let me know what you think.
