From 44e7475d40eb26b8d3a6e2b2f7a5f12a5fe0942e Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 27 Jun 2016 23:30:02 -0700 Subject: [PATCH] ARM: OMAP2+: Fix build if CONFIG_SMP is not set Looks like I only partially fixed up things if CONFIG_SMP is not set for the recent kexec changes. We don't have boot_secondary available without SMP as reported by Arnd.
