Subject: [PATCH 1/1] of: unittest: 64 bit dma address test requires arch support
Date: Sun, 12 Dec 2021 16:18:52 -0600	[thread overview]
Message-ID: <20211212221852.233295-1-frowand.list@gmail.com> (raw)

From: Frank Rowand <frank.rowand@sony.com>

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")
