Aneesh Kumar K.V b0aa44a3df powerpc/thp: Add write barrier after updating the valid bit 
With hugepages, we store the hpte valid information in the pte page
whose address is stored in the second half of the PMD. Use a
write barrier to make sure clearing pmd busy bit and updating
hpte valid info are ordered properly.
