    Subject[PATCH 5.16 0488/1039] of: unittest: 64 bit dma address test requires arch support
    Date
    From: Frank Rowand <frank.rowand@sony.com>

    [ Upstream commit 9fd4cf5d3571b27d746b8ead494a3f051485b679 ]

    If an architecture does not support 64 bit dma addresses then testing
    for an expected dma address >= 0x100000000 will fail.

    Fixes: e0d072782c73 ("dma-mapping: introduce DMA range map, supplanting dma_pfn_offset")
