From: Guo Ren <ren_guo@c-sky.com>
There is no present bit in csky pmd hardware, so we need to prepare invalid_pte_table for empty pmd entry and the functions (pmd_none & pmd_present) in pgtable.h need invalid_pte_talbe to get result. If a module use these functions, we need export the symbol for it.
