fix 25 section mismatch warnings..

The following set of patches fixes 25 Section mismatch warnings in following directories:

kernel/
mm/
drivers/pci
arch/x86/

When build individually they are now clean.

The shortlog:

Sam Ravnborg (11):
pci: fix section mismatch warnings referring to pci_do_scan_bus
pci: fix 4x section mismatch warnings
cpu: fix section mismatch warnings for enable_nonboot_cpus
cpu: fix section mismatch related to cpu_chain
cpu: do not annotate exported register_cpu_notifier()
cpu: silence section mismatch warnings for hotcpu notifies
mm: fix section mismatch warning in sparse.c
x86: fix section mismatch warning in acpi/boot.c
x86: silence section mismatch warning in smpboot_64.c
x86: fix section mismatch warning in kernel/pci-calgary
x86: fix section mismatch warnings when referencing notifiers

With these patches applied I have a clean build of arch/x86/ with an allyesconfig.

I expect Greg to pick up the pci patches - but as they conflict with patches recently posted by Adrian a qualified selection should be made.

The cpu patches are cc:ed to Gautham R Shenoy but I think they need to go in via Andrew.
The mm patch are cc:ed the Mel, Christoph and Andy but I think this one should also go in via Andrew.

The x86 patches are cc:ed to the x86 gang and should all go in via the x86 tree.

I would like some extra review of the following patches:
-> The pci patches
-> x86: silence section mismatch warning in smpboot_64.c

The others are more strightforward but please eye ball them too.

For my allyesconfig build I still has 116 warnings - but this is without Adrian's patches applied.
Of these 8 happens only when running the final check on vmlinux.o which is due to references between the sub directories (kernel/ <-> arch/x86/kernel/)

Patches follows unnumbered as they are independent of each other.
