From 7890f794e0e6f7dce2a5f4a03ba64b0b3fe306bd Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 15 Feb 2006 02:26:54 -0800 Subject: [SPARC64]: Add prom_{start,stop}cpu_cpuid(). Use prom_startcpu_cpuid() on SUN4V instead of prom_startcpu(). We should really test for "SUNW,start-cpu-by-cpuid" presence and use it if present even on SUN4U. Signed-off-by: David S.
