Date: Thu, 12 Feb 2015 20:42:33 +0100 From: Arnd Bergmann <arnd@...db.de> To: linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org, arm@...nel.org, Arnd Bergmann <arnd@...db.de>, Nicolas Pitre <nico@...aro.org>, Kevin Hilman <khilman@...aro.org>, Liviu Dudau <liviu.dudau@....com>, Sudeep Holla <sudeep.holla@....com>, Lorenzo Pieralisi <lorenzo.pieralisi@....com> Subject: [PATCH 01/11] ARM: vexpress: use ARM_CPU_SUSPEND if needed The vexpress tc2 power management code calls mcpm_loopback, which is only available if ARM_CPU_SUSPEND is enabled, otherwise we get a link error: arch/arm/mach-vexpress/built-in.o: In function `tc2_pm_init': arch/arm/mach-vexpress/tc2_pm.c:389: undefined reference to `mcpm_loopback' This explicitly selects ARM_CPU_SUSPEND like other platforms that need it.
