This also allows nearly all of vmx/main.c to go under a single #ifdef, eliminating trampolines in the generated code, and almost all of the stubs. For example, with CONFIG_KVM_INTEL_TDX=n, before this cleanup, vt_refresh_apicv_exec_ctrl() would produce: 0000000000036490 : 36490: f3 0f 1e fa endbr64 36494: e8 00 00 00 00 call 36499 36495: R_X86_64_PLT32 __fentry__-0x4 36499: e9 00 00 00 00 jmp 3649e 3649a: R_X86_64_PLT32 vmx_refresh_apicv_exec_ctrl-0x4 3649e: 66 90 xchg %ax,%ax After this patch, this is completely eliminated.
