3.16.81-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Lorenzo Pieralisi <lorenzo.pieralisi@xxxxxxx> commit 1b9bdf5c1661873a10e193b8cbb803a87fe5c4a1 upstream. The code enabled by the ARM_CPU_SUSPEND config option is used by kernel subsystems for purposes that go beyond system suspend so its config entry should be augmented to take more default options into account and avoid forcing its selection to prevent dependencies override. To achieve this goal, this patch reworks the ARM_CPU_SUSPEND config entry and updates its default config value (by adding the BL_SWITCHER option to it) and its dependencies (ARCH_SUSPEND_POSSIBLE), so that the symbol is still selected by default by the subsystems requiring it and at the same time enforcing the dependencies correctly.
