| |
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit 95fcedb027a27f32bf2434f9271635c380e57fb5 upstream.
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.
