Applied patch 2 to kvm-x86 fixes, with a tweaked changelog to call out that
TDX support hasn't yet been released, i.e. that there is no established ABI
to break.
Applied patch 1 to kvm-x86 misc, with tweaked documentation to not imply that
userspace "must" invoke the ioctl. I think this is the last patch I'll throw
into misc for 6.17? So in theory, if it breaks userspace, I can simply
truncate it from the pull request.
