Tim Schmielau 4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

Dave Airlie 7a9aff3cff drm: fix a bad VERSION check.
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)

Dave Airlie 6795c985a6 Add support for PCI MGA cards to MGA DRM.
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.

 cleanup patches will be needed)

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.
