KVM: TDX: Handle KVM hypercall with TDG.VP.VMCALL
Handle KVM hypercall for TDX according to TDX Guest-Host Communication
Interface (GHCI) specification.
The TDX GHCI specification defines the ABI for the guest TD to issue
hypercalls. When R10 is non-zero, it indicates the TDG.VP.VMCALL is
vendor-specific. KVM uses R10 as KVM hypercall number and R11-R14
as 4 arguments, while the error code is returned in R10.
Morph the TDG.VP.VMCALL with KVM hypercall to EXIT_REASON_VMCALL and
marshall r10~r14 from vp_enter_args to the appropriate x86 registers for
KVM hypercall handling.
