| Subject: MIPS: export has_transparent_hugepage() for modules |
| |
| From: Randy Dunlap <rdunlap@infradead.org> |
| |
| [ Upstream commit 31b4d8e172f614adc53ddecb4b6b2f6411a49b84 ] |
| |
| MIPS should export its local version of "has_transparent_hugepage" |
| so that loadable modules (dax) can use it. |
| |
| Fixes this build error: |
| ERROR: modpost: "has_transparent_hugepage" [drivers/dax/dax.ko] undefined! |
| |
| Fixes: fd8cfd300019 ("arch: fix has_transparent_hugepage()") |
