    ARM: 8612/1: LPAE: initialize cache policy correctly · 6b3142b2
    Stefan Agner authored
    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.
