Hi Dave and Alexey,
Regarding VMware-specific checks, it may be beneficial to add some
additional checks
such as ensuring that the hypervisor vendor is VMware,
r12==VMWARE_HYPERVISOR_MAGIC,
r10==VMWARE_TDX_VENDOR_LEAF, r11==VMWARE_TDX_HCALL_FUNC and r13 (command) is
restricted to those few command

VMware hypercalls use I/O port, VMCALL or VMMCALL instructions.
Add __tdx_hypercall path to support TDX guests.
No change in high bandwidth hypercalls, as only low bandwidth
ones are supported for TDX guests.
