From 3d1712c91df01d2573b934e972e231e8edb102c7 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Fri, 24 Mar 2006 03:15:11 -0800 Subject: [PATCH] x86_64: {set,clear,test}_bit() related cleanup and pci_mmcfg_init() fix While working on these patch set, I found several possible cleanup on x86-64 and ia64. akpm: I stole this from Andi's queue. Not only does it clean up bitops. It also unrelatedly changes the prototype of pci_mmcfg_init() and removes its arch_initcall(). It seems that the wrong two patches got joined together, but this is the one which has been tested. This patch fixes the current x86_64 build error (the pci_mmcfg_init() declaration in arch/i386/pci/pci.h disagrees with the definition in arch/x86_64/pci/mmconfig.c) This also means that x86_64's pci_mmcfg_init() gets called in the same (new) manner as x86's: from arch/i386/pci/init.c:pci_access_init(), rather than via initcall. The bitops cleanups came along for free. All this worked OK in -mm testing (since 2.6.16-rc4-mm1) because x86_64 was tested with both patches applied.
