Chris Goldsworthy 239dde6763 ANDROID: dma-direct: Make DMA32 disablement work for CONFIG_NUMA ...

zone_dma32_is_empty() currently lacks the proper validation to ensure
that the NUMA node ID it receives as an argument is valid. This has no
effect on kernels with CONFIG_NUMA=n as NODE_DATA() will return the
same pglist_data on these devices, but on kernels with CONFIG_NUMA=y,
this is not the case, and the node passed to NODE_DATA must be
validated.

Rather than trying to find the node containing ZONE_DMA32, replace
calls of zone_dma32_is_empty() with zone_dma32_are_empty() (which
iterates over all nodes and returns false if one of the nodes holds
DMA32 and it is non-empty).
