From 42aca483ddee8888926d913b660e1dd38d748ba9 Mon Sep 17 00:00:00 2001 From: Robin Holt Date: Mon, 28 Jul 2008 20:36:50 -0500 Subject: [PATCH] [IA64] Fix ia64 build failure when CONFIG_SFC=m CONFIG_SFC=m uses topology_core_siblings() which, for ia64, expects cpu_core_map to be exported. It is not. This patch exports the needed symbol. Maintainers note: This really looks like the wrong thing to do ... it would be much better for the kernel to export an API to provide drivers like this with data they need (which in the case of this driver seems to be an estimate of the effective parallelism available on the platform). But x86 has exported this forever ... so go with the flow until such an API is defined.
