[PATCH v4 2/7] arm64: mm: Move zone_dma_bits initialization into zone_sizes_init()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



zone_dma_bits's initialization happens earlier that it's actually
needed, in arm64_memblock_init(). So move it into the more suitable
zone_sizes_init().
