From 8a2d8693054a6cd86cc959576322b30e66e31208 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Thu, 19 Jul 2007 18:32:43 +0300 Subject: [PATCH] [IA64] Allow smp_call_function_single() to current cpu This removes the requirement for callers to get_cpu() to check in simple cases. i386 and x86_64 already received a similar treatment.
