From 7bc5c428a660d4d1bc95ba54bf4cb6bccf8c3029 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 8 Sep 2020 17:56:22 +0200 Subject: dma-direct: remove __dma_to_phys There is no harm in just always clearing the SME encryption bit, while significantly simplifying the interface.

Try to improve the situation by renaming __phys_to_dma to phys_to_dma_unencryped, and not forcing architectures that want to override phys_to_dma to actually provide __phys_to_dma.
