which arch is it? I have 3.14.18 working on my x86_64 laptop.

The config was modified from 3.14.17 -> .18:

@@ -484,7 +484,10 @@ CONFIG_SCHED_HRTICK=y
 # CONFIG_KEXEC is not set
 # CONFIG_CRASH_DUMP is not set
 CONFIG_PHYSICAL_START=0x1000000
-# CONFIG_RELOCATABLE is not set
+CONFIG_RELOCATABLE=y
+CONFIG_RANDOMIZE_BASE=y
+CONFIG_RANDOMIZE_BASE_MAX_OFFSET=0x20000000
+CONFIG_X86_NEED_RELOCS=y
 CONFIG_PHYSICAL_ALIGN=0x1000000
 CONFIG_HOTPLUG_CPU=y
 # CONFIG_BOOTPARAM_HOTPLUG_CPU0 is not set

Mostly due to be similar x86_64, which recently got requirement of
CONFIG_RELOCATABLE for EFI (and it looked like a good thing to have
anyways).
