[RFC PATCH 3/7] ARM: realview: use central SMP spin-table routines

From: Alex Elder
Date: Fri Mar 28 2014 - 17:14:27 EST


This is the first of three patches involved replacing the use of smp
operations defined under arch/arm/mach-versatile. Both realview and
vexpress use the same smp_boot_secondary and smp_secondary_init
functions, and those are equivalent to the common ones now available
in arch/arm/kernel/smp.c.

We can't get rid of the mach-versatile functions yet, so this patch
just switches mach-realview to use the common routines.
