ARM: SMP: basic IPI triggered completion support We need a mechanism to let an inbound CPU signal that it is alive before even getting into the kernel environment i.e. from early assembly code. Using an IPI is the simplest way to achieve that. This adds some basic infrastructure to register a struct completion pointer to be "completed" when the dedicated IPI for this task is received.
