b0385146bc uninorth-agp section mess
'aperture' is declared devinitdata (the whole word of it) and
is used from ->fetch_size() which can, AFAICS, be used on
!HOTPLUG after init time.

5f310b6378 agp: enable optimized agp_alloc_pages methods
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.

a030ce4477 [AGPGART] Allow drm-populated agp memory types
This patch allows drm to populate an agpgart structure with pages of its own.
It's needed for the new drm memory manager which dynamically flips pages in and out of AGP.

The patch modifies the generic functions as well as the intel agp driver. The intel drm driver is
currently the only one supporting the new memory manager.

Other agp drivers may need some minor fixing up once they have a corresponding memory manager enabled drm driver.

AGP memory types >= AGP_USER_TYPES are not populated by the agpgart driver, but the drm is expected
to do that, as well as taking care of cache- and tlb flushing when needed.

It's not possible to request these types from user space using agpgart ioctls.

The Intel driver also gets a new memory type for pages that can be bound cached to the intel GTT.

18088748d2 [AGPGART] uninorth: Add module param 'aperture' for aperture size
In contrast to most if not all PC BIOSes, OpenFirmware (OF) on PowerMacs with
UniNorth bridges does not allow changing the aperture size. The size set up by
OF is usually 16 MB, which is too low for graphics intensive environments.
Hence, add a module parameter that allows changing the aperture size at driver
initialization time. When the parameter is not specified, the default is 32 MB.

Enablement patch for the new PowerBooks (late 2005 edition).

This enables the ATA controller, Gigabit ethernet and basic AGP setup.

Still remaining is to get the touchpad to work, the simple change of just
adding the new USB ids isn't enough.

07eee78ea8 [PATCH] AGP fix for Xen VMM
When Linux is running on the Xen virtual machine monitor, physical
addresses are virtualised and cannot be directly referenced by the AGP
GART.  This patch fixes the GART driver for Xen by adding a layer of
abstraction between physical addresses and 'GART addresses'.

Architecture-specific functions are also defined for allocating and freeing
the GATT.  Xen requires this to ensure that table really is contiguous from
the point of view of the GART.

These extra interface functions are defined as 'no-ops' for all existing
architectures that use the GART driver.

0c541b4406 [PATCH] ppc32: Fix AGP and sleep again
My previous patch that added sleep support for uninorth-agp and some AGP
"off" stuff in radeonfb and aty128fb is breaking some configs.  More
specifically, it has problems with rage128 setups since the DRI code for
these in X doesn't properly re-enable AGP on wakeup or console switch
(unlike the radeon DRM).

This patch fixes the problem for pmac once for all by using a different
approach.  The AGP driver "registers" special suspend/resume callbacks with
some arch code that the fbdev's can later on call to suspend and resume
AGP, making sure it's resumed back in the same state it was when suspended.
 This is platform specific for now.  It would be too complicated to try to
do a generic implementation of this at this point due to all sort of weird
things going on with AGP on other architectures.  We'll re-work that whole
problem cleanly once we finally merge fbdev's and DRI.

In the meantime, please apply this patch which brings back some r128 based
laptops into working condition as far as system sleep is concerned.

1da177e4c3 Linux-2.6.12-rc2
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!
