c42856af8f70d983 ("KVM: TDX: Add a place holder for handler of TDX hypercalls (TDG.VP.VMCALL)")
That makes 'perf kvm-stat' aware of these new TDCALL and
MSR_{READ,WRITE}_IMM exit reasons, thus addressing the following perf
build warning:
Warning: Kernel ABI header differences:
diff -u tools/arch/x86/include/uapi/asm/vmx.h arch/x86/include/uapi/asm/vmx.h
Please see tools/include/uapi/README for further details.

But this time causes no changes in tooling results, as the introduced
SVM_VMGEXIT_SAVIC exit reason wasn't added to SVM_EXIT_REASONS, that is
used in kvm-stat.c.
And addresses this perf build warning:
