This change runs afoul of the recently merged 8eb3751c73bec
("selftests: vm: Fix incorrect kernel headers search path").
I did this:
--- a/tools/testing/selftests/mm/Makefile~selftests-mm-add-new-selftests-for-ksm
+++ b/tools/testing/selftests/mm/Makefile
@@ -29,7 +29,7 @@ MACHINE ?= $(shell echo $(uname_M) | sed -e 's/aarch64.*/arm64/' -e 's/ppc64.*/p
# LDLIBS.
MAKEFLAGS += --no-builtin-rules
-CFLAGS = -Wall -I $(top_srcdir) $(EXTRA_CFLAGS) $(KHDR_INCLUDES)
+CFLAGS = -Wall -I $(top_srcdir) -I $(top_srcdir)/tools/include/uapi $(EXTRA_CFLAGS) $(KHDR_INCLUDES)
LDLIBS = -lrt -lpthread
TEST_GEN_FILES = cow
TEST_GEN_FILES += compaction_test

But I expect it's a bit wrong. Please check?
