[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.
