x86_64 vsyscall fails to compile when CONFIG_HOTPLUG_CPU is disabled
The following change attempted to fix up the notifier structure when CONFIG_HOTPLUG_CPU is disabled:
[PATCH] x86-64: Fix vgetcpu when CONFIG_HOTPLUG_CPU is disabled
It seems to leave a reference to the cpu_vsyscall_notifier which is not declared unles CONFIG_HOTPLUG_CPU is defined, leading to the following compile time error:
arch/x86_64/kernel/vsyscall.c:310: error: `cpu_vsyscall_notifier' undeclared (first use in this function)
Make the hotcpu_notifier dependant on CONFIG_HOTPLUG_CPU.
