[ 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()")
