Yes, some patches in other Pkg.
Patch in UefiCpuPkg have been merged.
It provide a mode allow cpu which in SMM mode work without waiting for
other APs enter SMM mode.
And define a new service that can be used by SMI handler to optionally wait
for other APs to complete SMM rendezvous.
Patch in UefiPayloadPkg in review.
Use VariableSmm driver so that need to add SmmCpuRendezvousLib dependency.
Patch in MdeModulePkg is blocked.
VariableSmm/VariableStandaloneMM driver needs use new service complete SMM
rendezvous.
Patch in SecurityPkg is blocked.
TcgSmm/Tcg2Smm driver need use new service complete SMM rendezvous.
Thanks a lot.

Is this a standalone patch? Or one of a series patch?
I think it should be later. But, please enlighten me.
