From 6cd10f8db385ba547811baa5b26f672fdff232e6 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Sun, 9 Nov 2008 11:53:14 -0600 Subject: x86, voyager: fix smp generic helper voyager breakage Impact: build/boot fix for x86/Voyager This change: | commit 3d4422332711ef48ef0f132f1fcbfcbd56c7f3d1 | Author: Jens Axboe | Date: Thu Jun 26 11:21:34 2008 +0200 | | Add generic helpers for arch IPI function calls didn't wire up the voyager smp call function correctly, so do that here. Also make CONFIG_USE_GENERIC_SMP_HELPERS a def_bool y again, since we now use the generic helpers for every x86 architecture.
