[Xen-devel] [RFC v3 01/45] powerpc: dma-mapping: Don't hard-code the value of DMA_ATTR_WEAK_ORDERING

[Krzysztof Kozlowski <k.kozlowski@xxxxxxxxxxx>]

Hard-coded value of DMA_ATTR_WEAK_ORDERING is then compared with the
symbol.  This will stop matching if the value of symbol is changed (when
switching DMA attributes to unsigned long).
