+[PATCH] delay the creation of include/config/auto.conf
+
+Upstream-Statue: Pending
+
+config.mk will be included only if auto.conf is newer than .config
+but in some system, the HPET is not enabled, the smallest unit of
+time is second, and can not decise which file is newer, even if
+the correct dependency has been created.
+
+The below shows unit of time:
+
+under SUSE Linux Enterprise Desktop 11 SP2  (i586):
+    $ls --full-time include/config/auto.conf .config
+    2015-07-27 03:46:20.000000000 -0400 .config
+    2015-07-27 03:46:20.000000000 -0400 include/config/auto.conf
+    $
+
+under Ubuntu 14.04 LTS:
+    $ ls --full-time include/config/auto.conf .config
+    2015-07-27 13:40:14.008703027 +0800 .config
+    2015-07-27 13:40:15.020703054 +0800 include/config/auto.conf
+    $
+
+The rule of including config.mk in Makefile as below
+    autoconf_is_current := $(if $(wildcard $(KCONFIG_CONFIG)),$(shell find . \
+                    -path ./include/config/auto.conf -newer $(KCONFIG_CONFIG)))
+    ifneq ($(autoconf_is_current),)
+    include $(srctree)/config.mk
+    include $(srctree)/arch/$(ARCH)/Makefile
+    endif
+
+The compilation will be failed if config.mk is not included
+so delay 1 second to create auto.conf after creating of .config
