Subject: [PATCH 00/11] x86/virt/tdx: Add SEAMCALL wrappers for KVM

This is a completed version of Rick's RFC series at
https://lore.kernel.org/r/20241115202028.1585487-1-rick.p.edgecombe@intel.com/.

I took all the "Add SEAMCALL wrappers" patches from the various
TDX parts and placed them in a single series, so that they can be
reviewed and provided in a topic branch by Dave.

I will rebase kvm-coco-queue on top of these, but it's New Year's
Day and I only have a few minutes before turning off the computer
for good for a few days, so I'm not sure I will manage to push the
result.

In the meanwhile, this gives people time to review while I'm not
available.
