The cachepolicy variable gets initialized using a masked pmd value. So far, the pmd has been masked with flags valid for the 2-page table format, but the 3-page table format requires a different mask. On LPAE, this lead to a wrong assumption of what initial cache policy has been used. Later a check forces the cache policy to writealloc and prints the following warning: Forcing write-allocate cache policy for SMP This patch introduces a new definition PMD_SECT_CACHE_MASK for both page table formats which masks in all cache flags in both cases.
