Subject: [PATCH 3.5 64/64] PCI: fix truncation of resource size to 32 bits

3.5.7.24 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nikhil P Rao <nikhil.rao@...el.com>

commit d6776e6d5c2f8db0252f447b09736075e1bbe387 upstream.

_pci_assign_resource() took an int "size" argument, which meant that
sizes larger than 4GB were truncated.  Change type to resource_size_t.
