Robin Murphy 676bd99178 dmapool: fix overflow condition in pool_find_page() ... If a DMA pool lies at the very top of the dma_addr_t range (as may happen with an IOMMU involved), the calculated end address of the pool wraps around to zero, and page lookup always fails. Tweak the relevant calculation to be overflow-proof.
