From fc1b6620501f1a4b88f583549c63666180bea177 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 2 Apr 2021 16:33:12 +0200 Subject: iommu/amd: Move a few prototypes to include/linux/amd-iommu.h A few functions that were intentended for the perf events support are currently declared in arch/x86/events/amd/iommu.h, which mens they are not in scope for the actual function definition. Also amdkfd has started using a few of them using externs in a .c file. End that misery by moving the prototypes to the proper header.
