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!
