From 85a5a6875ca93dc4efbf20df942ba41d27a917e3 Mon Sep 17 00:00:00 2001 From: Jianxiong Gao Date: Thu, 29 Apr 2021 17:33:13 +0000 Subject: [PATCH] swiotlb: don't modify orig_addr in swiotlb_tbl_sync_single commit: 16fc3cef33a04632ab6b31758abdd77563a20759 swiotlb_tbl_map_single currently nevers sets a tlb_addr that is not aligned to the tlb bucket size. But we're going to add such a case soon, for which this adjustment would be bogus.
