From 5135d875e1457ef946a055003d8f80713e862135 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Tue, 27 Nov 2012 21:54:41 -0500 Subject: 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.
