The changes from v2 here mostly come from Xiaoyao's review, with which
I mostly agreed:
- moving the preparation for user return notifiers to prepare_switch_to_host,
- squashing "x86/virt/tdx: Make tdh_vp_enter() noinstr" into patch 1
- dropping "KVM: TDX: Set arch.has_protected_state
to true" which is now part of one of the earlier series.
- replacing TDX_REGS_UNSUPPORTED_SET with the strict list of registers
that (at least potentially) are made available in unencrypted form
The major change however is rewriting "KVM: TDX: restore host xsave
state when exit from the guest TD" to not use kvm_load_host_xsave_state().
There's a disagreement between me and Sean on that topic, but posting
the patches is the best way to clear that up. Also for this reason I'm
including an extra patch at the end providing the hunks that were (or
should be) only needed in order to appease kvm_load_host_xsave_state();
I have tested without it and unlike the rest it is not included in kvm-coco-queue.
