[PATCH] x86/head64: define early_idt_ripmsg only if CONFIG_KALLSYMS is enabled

From: Alexander Kuleshov
Date: Sat Jan 30 2016 - 09:19:33 EST


We have definition of the early_idt_ripmsg which represents string header
for the output of the kernel symbols during early exception. But it will
be used only if CONFIG_KALLSYMS is enabled.
