From 0d7a91678aaacf8e2f532c3e04a276af06b42d1c Mon Sep 17 00:00:00 2001 From: Mathieu Desnoyers Date: Fri, 27 Jan 2023 08:57:52 -0500 Subject: [PATCH] selftests: iommu: Use installed kernel headers search path Use $(KHDR_INCLUDES) as lookup path for installed kernel headers rather than using kernel headers in include/uapi from the source kernel tree kernel headers. Remove bogus ../../../../include/ from the search path, because kernel source headers are not needed by those user-space selftests, and it causes issues because -I paths are searched before -isystem paths, and conflicts for files appearing both in kernel sources and in uapi headers with incompatible semantics (e.g. types.h).
