From 36e235901f90fb83215be43cbd8f1ca14661ea40 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox <matthew@wil.cx> Date: Tue, 10 Jul 2007 10:54:40 -0600 Subject: [PATCH] PCI: Only build PCI syscalls on architectures that want them The PCI syscalls are built on every architecture except X86, but only a few have ever hooked them up. Use a new Kconfig symbol to save a couple of kB on the architectures that have never used the syscalls. Tested on x86 and ia64 only.
