+Subject: kbuild: Fix include path in scripts/Makefile.modpost
+
+From: Jing Leng <jleng@ambarella.com>
+
+commit 23a0cb8e3225122496bfa79172005c587c2d64bf upstream.
+
+When building an external module, if users don't need to separate the
+compilation output and source code, they run the following command:
+"make -C $(LINUX_SRC_DIR) M=$(PWD)". At this point, "$(KBUILD_EXTMOD)"
+and "$(src)" are the same.
+
+If they need to separate them, they run "make -C $(KERNEL_SRC_DIR)
+O=$(KERNEL_OUT_DIR) M=$(OUT_DIR) src=$(PWD)". Before running the
+command, they need to copy "Kbuild" or "Makefile" to "$(OUT_DIR)" to
+prevent compilation failure.
+
+So the kernel should change the included path to avoid the copy operation.

+[masahiro: I do not think "M=$(OUT_DIR) src=$(PWD)" is the official way,
+but this patch is a nice clean up anyway.]
