Message-ID: <20180416112724.9677-2-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20180416112724.9677-1-aneesh.kumar@linux.ibm.com>
8xx use slice code when hugetlbfs is enabled. We missed a header include on
8xx which resulted in the below build failure.
config: mpc885_ads_defconfig + CONFIG_HUGETLBFS
CC arch/powerpc/mm/slice.o
arch/powerpc/mm/slice.c: In function 'slice_get_unmapped_area':
