Andrew, you don't have to apply this patch. It is supposed to be picked
by Greg.
There seems to be some confusion. Just few days back Greg consolidated
and re-organized all the 64bit resources patches and posted on LKML for
review.

There were few review comments regarding kconfig options.
I reworked the patch and CONFING_RESOURCES_32BIT was changed to
CONFIG_RESOURCES_64BIT.
http://marc.theaimsgroup.com/?l=linux-kernel&m=115072559700302&w=2
Now Greg's tree and your tree are not exact replica when it comes to
64bit resource patches. Hence this patch is supposed to be picked by
Greg to make sure things are not broken in his tree.
Thanks
Vivek
