From 3b16cf874861436725c43ba0b68bdd799297be7c Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 26 Jun 2008 11:21:54 +0200 Subject: x86: convert to generic helpers for IPI function calls This converts x86, x86-64, and xen to use the new helpers for smp_call_function() and friends, and adds support for smp_call_function_single().
