Subject: [PATCH 3.16 060/127] PCI: Add missing MEM_64 mask in pci_assign_unassigned_bridge_resources()

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

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

From: Yinghai Lu <yinghai@...nel.org>

commit d61b0e87d2dfba3706dbbd6c7c6fd41c3d845685 upstream.

In 5b28541552ef ("PCI: Restrict 64-bit prefetchable bridge windows to
64-bit resources"), we added IORESOURCE_MEM_64 to the mask in
pci_assign_unassigned_root_bus_resources(), but not to the mask in
pci_assign_unassigned_bridge_resources().

Add IORESOURCE_MEM_64 to the pci_assign_unassigned_bridge_resources() type
mask.

Fixes: 5b28541552ef ("PCI: Restrict 64-bit prefetchable bridge windows to 64-bit resources")
