HKID
It's better to use consistent words throughout patch/series I guess.

Perhaps explicitly call out the hook is vm_free() and why the existing
vm_destroy() hook cannot meet TDX's purpose, so that people can understand
easily why you need vm_free().

Why -1? Can it be set to 0, which is the initial value when kvm_tdx is allocated
anyway?

I am wondering why this 'struct tdx_td_page' is needed?
It appears the page->pa is used by SEAMCALLs and page->va is used by
tdx_clear_page() as MOVDIR64B needs a virtual address.
But since GFP_KERNEL_ACCOUNT is used in memory allocation, so you can actually
just get the pa and va from the page easily (using page_to_phys() and __va()).
Also it's 64-bit kernel so you don't even need to consider HIGHMEM.
Also, it seems page->added can be replaced with simply checking whether page is
NULL, correct?
Btw, I think the introduce of 'struct tdx_td_page' and the new 'struct
tdx_td_page tdr' to 'struct kvm_tdx' should come together with this patch, but
not in the previous patch "KVM: TDX: Stub in tdx.h with structs, accessors, and
VMCS helpers". This makes the code review easier.
The "accessors" can be introduced in later patch when they are needed -- it
doesn't seem any of them is used in this patch?
