[PATCH v12 01/15] PCI: Let pci_mmap_page_range() take extra resource pointer
From: Yinghai Lu <yinghai@kernel.org>
Date: 2016-06-04 00:08:12
This one is preparing patch for next one: PCI: Let pci_mmap_page_range() take resource addr We need to pass extra resource pointer to avoid searching that again for powerpc and microblaze prot set operation.
