Kishon Vijay Abraham I 1edfff795d dma-direct: fix data truncation in dma_direct_get_required_mask() ... [ Upstream commit cdcda0d1f8 ] The upper 32-bit physical address gets truncated inadvertently when dma_direct_get_required_mask() invokes phys_to_dma_direct(). This results in dma_addressing_limited() return incorrect value when used in platforms with LPAE enabled. Fix it here by explicitly type casting 'max_pfn' to phys_addr_t in order to prevent overflow of intermediate value while evaluating '(max_pfn - 1) << PAGE_SHIFT'.
