| |
When PM_SLEEP_SMP is enabled and HOTPLUG_CPU is disabled, it results in the following Kbuild warning:
WARNING: unmet direct dependencies detected for HOTPLUG_CPU Depends on [n]: SMP [=y] && (PPC_PSERIES [=n] || PPC_PMAC [=n] || PPC_POWERNV [=n] || FSL_SOC_BOOKE [=n]) Selected by [y]: - PM_SLEEP_SMP [=y] && SMP [=y] && (ARCH_SUSPEND_POSSIBLE [=n] || ARCH_HIBERNATION_POSSIBLE [=y]) && PM_SLEEP [=y]
The reason is that PM_SLEEP_SMP selects HOTPLUG_CPU without depending on or selecting HOTPLUG_CPU's dependencies.
Let PM_SLEEP_SMP depend on HOTPLUG_CPU instead to avoid Kbuild issues.
