+# the original Makefile was trashed and replaced by this one
+# The main reason is that loadable modules should be built with
+# the same compile flags the kernel was built with, so we'd better
+# let the kernel tree build the module for us, like that :
+#
+#   make -C $(KERNEL_DIR) SUBDIRS="$(shell pwd)" modules
+#   make -C $(KERNEL_DIR) SUBDIRS="$(shell pwd)" modules_install
+#
+#
+# $(TOPDIR)/lib/string.o is needed at link time because the memchr function 
+# is not exported on mips (insmod: unresolved symbol memchr)
