From b5e350f919acb8ef6961bc1b62e395f53cea123a Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 3 Jan 2014 18:29:00 -0700 Subject: agp/intel: Use pci_bus_address() to get GTTADR bus address Per the Intel 915G/915GV/... Chipset spec (document number 301467-005), GTTADR is a standard PCI BAR. The PCI core reads GTTADR at enumeration-time. Use pci_bus_address() instead of reading it again in the driver. This works correctly for both 32-bit and 64-bit BARs. The spec above only mentions 32-bit GTTADR, but we should still use the standard interface.
