This patch contains the following small cleanups:
- make two needlessly global functions static
- drm_sysfs.c: every file should #include the header with the prototypes
of the global functions it is offering

I found why my G5 was crashing when using the linux-2.6 version of the
DRM + git-drm.patch from 2.6.13-rc6-mm1, but not with the CVS DRM.
The reason was that dev->agp->cant_use_aperture wasn't getting set,
and the reason for that was that <linux/version.h> no longer gets
included and the #if LINUX_VERSION_CODE < 0x020408 in drm_agpsupport.c
was going the wrong way. With this patch (and a few others) a 32-bit
server works correctly, as does DRI.

This converts the drm_handle_t to unsigned int.
This is currently safe to do as we don't pass these across the kernel/user
boundary, but userspace does use these, but no-one builds userspace against
the kernel headers at present so it is okay to switch over the kernel copy
of drm.h at this point. (The CVS tree will switch over soon in sync with
some Mesa changes)

I basically combined Paul's patches with additions that I had made
for PCI scatter gather.
I also tried more carefully to avoid problems with the same token
assigned multiple times while trying to use the base address in the
token if possible to gain as much backward compatibility as possible
for broken DRI clients.

This patch adds serveral new ioctls and a new query to get_param query to
support PCI MGA cards.
Two ioctls were added to implement interrupt based waiting. With this change,
the client-side driver no longer needs to map the primary DMA region or the
MMIO region. Previously, end-of-frame waiting was done by busy waiting in the
client-side driver until one of the MMIO registers (the current DMA pointer)
matched a pointer to the end of primary DMA space. By using interrupts, the
busy waiting and the extra mappings are removed.
A third ioctl was added to bootstrap DMA. This ioctl, which is used by the
X-server, moves a *LOT* of code from the X-server into the kernel. This allows
the kernel to do whatever needs to be done to setup DMA buffers. The entire
process and the locations of the buffers are hidden from user-mode.
Additionally, a get_param query was added to differentiate between G4x0 cards
and G550 cards. A gap was left in the numbering sequence so that, if needed,
G450 cards could be distinguished from G400 cards. According to Ville
Syrjälä, the G4x0 cards and the G550 cards handle anisotropic filtering
differently. This seems the most compatible way to let the client-side driver
know which card it's own. Doing this very small change now eliminates the
need to bump the DRM minor version twice.

Added device_is_agp callback to drm_driver. This function is called by the
platform-specific drm_device_is_agp function. Added implementation of this
function the the Linux-specific portion of the MGA driver to detect PCI G450
cards. Added code to the Linux-specific portion of the generic DRM layer to
not initialize AGP infrastructure if the card is not AGP (this matches what
already existed in BSD).
Fix up i810/i830 and i915 drivers to always return AGP as they don't always
report the capability.
Fix the MGA to not report AGP for a card that has an AGP chip behind a PCI
bridge.

After the previous fix in 2.6.12, this patch should properly fix the
radeon IRQ handling code.

The patch is against a 2.6.11 kernel tree. I am running this with a
32-bit X server (compiled up from X.org CVS as of a couple of weeks
ago) and 32-bit DRI libraries and clients. All the userland stuff is
identical to what I am using under a 32-bit kernel on my G4 powerbook
(which is a 32-bit machine of course). I haven't tried compiling up a
64-bit X server or clients yet.
In the compatibility routines I have assumed that the kernel can
safely access user addresses after set_fs(KERNEL_DS). That is, where
an ioctl argument structure contains pointers to other structures, and
those other structures are already compatible between the 32-bit and
64-bit ABIs (i.e. they only contain things like chars, shorts or
ints), I just check the address with access_ok() and then pass it
through to the 64-bit ioctl code. I believe this approach may not
work on sparc64, but it does work on ppc64 and x86_64 at least.
One tricky area which may need to be revisited is the question of how
to handle the handles which we pass back to userspace to identify
mappings. These handles are generated in the ADDMAP ioctl and then
passed in as the offset value to mmap. However, offset values for
mmap seem to be generated in other ways as well, particularly for AGP
mappings.
The approach I have ended up with is to generate a fake 32-bit handle
only for _DRM_SHM mappings. The handles for other mappings (AGP, REG,
FB) are physical addresses which are already limited to 32 bits, and
generating fake handles for them created all sorts of problems in the
mmap/nopage code.
This patch has been updated to use the new compatibility ioctls.
