> Please, where SMM_TASK_STATE_SEG is used?

SMM_TASK_STATE_SEG is used by setup_smm_descriptor() (security/intel/stm/StmPlatformSmm.c) as part of its setting up the smm descriptor.  The smm descriptor is used by the STM to setup the virtual machine runtime environment for the SMI handler.  In this case, the GDT referenced is the smm_relocate_gdt found in cpu/x86/smm/smm_stub.S
