	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).

2022-11-30	iommufd: Add a selftest	Jason Gunthorpe	1	-0/+12
	Cover the essential functionality of the iommufd with a directed test from userspace. This aims to achieve reasonable functional coverage using the in-kernel self test framework. A second test does a failure injection sweep of the success paths to study error unwind behaviors. This allows achieving high coverage of the corner cases in pages.c. The selftest requires CONFIG_IOMMUFD_TEST to be enabled, and several huge pages which may require: echo 4 > /proc/sys/vm/nr_hugepages Link: https://lore.kernel.org/r/19-v6-a196d26f289e+11787-iommufd_jgg@nvidia.com Tested-by: Nicolin Chen <nicolinc@nvidia.com> Tested-by: Matthew Rosato <mjrosato@linux.ibm.com> # s390 Tested-by: Yi Liu <yi.l.liu@intel.com> Tested-by: Eric Auger <eric.auger@redhat.com> # aarch64 Signed-off-by: Nicolin Chen <nicolinc@nvidia.com> Signed-off-by: Yi Liu <yi.l.liu@intel.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
