Some documentation remain in v6.10-rc1:

$ git grep -w p.d_huge
Documentation/mm/arch_pgtable_helpers.rst:| pmd_huge                  | 
Tests a HugeTLB mapped PMD                       |
Documentation/mm/arch_pgtable_helpers.rst:| pud_huge                  | 
Tests a HugeTLB mapped PUD                       |
arch/x86/mm/pat/set_memory.c:            * otherwise 
pmd_present/pmd_huge will return true
