Subject: [PATCH] ARM64: kernel: compiling issue, duplicate definition of early_console

From: [email-masked] (Chen Gang)
Date: Fri, 19 Apr 2013 18:53:07 +0800

when compiling with allmodconfig.
    early_console is already defined as an extern global pointer.

  need let it point to the object which we intend to (like ARM32 done).
