From 74bcc2499291d38b6253f9dbd6af33a195222208 Mon Sep 17 00:00:00 2001 From: Leif Lindholm Date: Fri, 23 May 2014 14:16:56 +0100 Subject: arm64: efi: only attempt efi map setup if booting via EFI Booting a kernel with CONFIG_EFI enabled on a non-EFI system caused an oops with the current UEFI support code. Add the required test to prevent this.
