From 0f7b332f9777819a39a3b325690379a7efef89d1 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 3 Apr 2011 13:01:30 +0100 Subject: ARM: consolidate SMP cross call implementation Rather than having each platform class provide a mach/smp.h header for smp_cross_call(), arrange for them to register the function with the core ARM SMP code instead.
