Memory used to hold the page tables is allocated from the top of RAM with no prior initialization and could therefore hold invalid data. As invalidate_dcache_all() will be called before the MMU has been initialized and as that function relies indirectly on the page tables when using CMO_BY_VA_ONLY, these must be in a valid state from their allocation.
