; NASM doesn't support the vmmcall instruction in 32-bit mode and NASM versions
; before 2.12 cannot translate the 64-bit "rep vmmcall" instruction into elf32
; format. Given that VMGEXIT does not make sense on IA32, provide a stub
; implementation that is identical to CpuBreakpoint(). In practice,
; AsmVmgExitSvsm() should never be called on IA32.
