| Subject: csky/mm: Fixup export invalid_pte_table symbol |
| |
| From: Guo Ren <guoren@linux.alibaba.com> |
| |
| [ Upstream commit 7f4a567332f035ab16b29010fbd04a0f10183c77 ] |
| |
| 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. |
