section mismatch warnings in current git head for powerpc

I got the following warnings when building current git head for powerpc 64bit:

  LD      net/ipv4/built-in.o
  LD      drivers/scsi/built-in.o
  LD      net/built-in.o
  LD      drivers/built-in.o
  LD      vmlinux.o

MODPOST vmlinux.o
WARNING: vmlinux.o(.text+0x73bc): Section mismatch in reference from the function .start_secondary_prolog() to the function .devinit.text:.start_secondary() The function .start_secondary_prolog() references
the function __devinit .start_secondary().
This is often because .start_secondary_prolog lacks a __devinit
annotation or the annotation of .start_secondary is wrong.

WARNING: vmlinux.o(.text+0x260a8): Section mismatch in reference from the function .pci_dn_reconfig_notifier() to the function .devinit.text:.update_dn_pci_info() The function .pci_dn_reconfig_notifier() references
the function __devinit .update_dn_pci_info().
This is often because .pci_dn_reconfig_notifier lacks a __devinit
annotation or the annotation of .update_dn_pci_info is wrong.

Is this anything to worry about?

Thanks,
Chris

Something that should be fixed, but not something to worry about. Similar warnings appear when building the kernel for x86_64. See also
http://lkml.org/lkml/2008/4/13/98, http://lkml.org/lkml/2008/4/17/202
and http://bugzilla.kernel.org/show_bug.cgi?id=9974.

start_secondary_prolog() is in asm, so I don't know what you're supposed to do with that.

I think pci_dn_reconfig_notifier() could be __devinit, but it's not clear because the code that calls it is not __devinit or conditional on HOTPLUG, eventhough in practice I think it is only used for hotplug.
