+Subject: [PATCH] arm64/crypto: fix makefile rule for aes-glue-%.o
+
+This fixes the following build failure when building with CONFIG_MODVERSIONS
+enabled:
+
+  CC [M]  arch/arm64/crypto/aes-glue-ce.o
+ld: cannot find arch/arm64/crypto/aes-glue-ce.o: No such file or directory
+make[1]: *** [arch/arm64/crypto/aes-ce-blk.o] Error 1
+make: *** [arch/arm64/crypto] Error 2
+
+The $(obj)/aes-glue-%.o rule only creates $(obj)/.tmp_aes-glue-ce.o, it
+should use if_changed_rule instead of if_changed_dep.
