The URL above also says: "Tests are intended to be run after building,
installing and booting a kernel".

Please build selftests with installed kernel headers corresponding to the
installed kernel.

Alternatively, tools/testing/selftests/lib.mk could be extended
to include uapi headers from the kernel tree into CPPFLAGS, e.g.

diff --git a/tools/testing/selftests/lib.mk b/tools/testing/selftests/lib.mk
index 1c8a1963d03f..b5f4f0fb8eeb 100644
--- a/tools/testing/selftests/lib.mk
+++ b/tools/testing/selftests/lib.mk
@@ -10,6 +10,9 @@ ifeq (0,$(MAKELEVEL))
 endif
 selfdir = $(realpath $(dir $(filter %/lib.mk,$(MAKEFILE_LIST))))
 
+uapi_dir = $(realpath $(selfdir)/../../../include/uapi)
+CPPFLAGS += -I$(uapi_dir)
+
 # The following are built by lib.mk common compile rules.
 # TEST_CUSTOM_PROGS should be used by tests that require
 # custom build rule and prevent common build rule use.
