Per the AGP 3.0 spec, APBASE is a standard PCI BAR and may be either 32
bits or 64 bits wide. Many drivers read APBASE directly, but they only
handled 32-bit BARs.
The PCI core reads APBASE 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.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.

SIS 760 is listed in the device tables for both amd64-agp and sis-agp.
amd64-agp is apparently preferable since it has workarounds for some
BIOS misconfigurations that sis-agp doesn't handle.

Convert most AGP chipset to use scratch page as default entries.
This help avoiding GPU querying 0 address and trigger computer
fault. With KMS and memory manager we bind/unbind AGP memory
constantly and it seems that some GPU are still doing AGP
traffic even after GPU report being idle with the memory segment.
Tested (radeon GPU KMS + Xorg + compiz + glxgears + quake3) on :
- SIS 1039:0001 & 1039:0003
- Intel 865 8086:2571
Compile tested for other bridges
V2 enable scratch page on uninorth
V3 fix unbound check in uninorth insert memory (Michel Dänzer)
V4 rebase on top of drm-next branch with the lastest intel AGP
changeset (stable should use version V3 of the patch)

The pageattr-array patch that you currently have in tip/master only
enables it for intel-agp, not the others. The attached enables it for
all drivers currently directly using agp_generic_alloc_page() and
agp_generic_destroy_page() (ocal driver is amd-k7-agp).
The new agp_generic_alloc_pages() interface uses the also new
pageattr array interface API. This makes all AGP drivers that
up to now used generic_{alloc,destroy}_page() use it.

For some vendor/id pairs the kernel will autoload both the sis-agp and the
amd64_agp modules as the sis-agp module will load for all sis devices.
This collision causes the bug reported in:
http://bugzilla.novell.com/show_bug.cgi?id=248665
As currently sis_probe does its own matching, requesting the whole range
gains nothing. The clean fix seems to me to leave the matching to the core
and advertise only the devices actually supported. This patch does so.

This updates .owner field of struct pci_driver.
This allows SYSFS to create the symlink from the driver to the module which

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
