The commit80e67af9afadded support for the generic work area concept used mainly by the encrypted VMs. In the past, the work area was preliminary used by the SEV-ES VMs. The SEV-ES support is available for the X64 builds only. But now, that work area header contains fields that nonencrypted VMs and SEV VMs can use. They can be built for IA32. So, moving the work area defines outside of X64.
