misc_open() looks fine, but who knows what all of the misc drivers are
doing in their open() functions?

* 'drm-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: (21 commits)
drm: only trust core drm ioctls - driver ioctls are a mess.
drm/i915: add support for Intel series 4 chipsets.
drm/radeon: add hier-z registers for r300 and r500 chipsets
drm/radeon: use DSTCACHE_CTLSTAT rather than RB2D_DSTCACHE_CTLSTAT
drm/radeon: switch IGP gart to use radeon_write_agp_base()
drm/radeon: Restore sw interrupt on resume
drm/r500: add support for AGP based cards.
drm/radeon: fix texture uploads with large 3d textures (bug 13980)
drm/radeon: add initial r500 support.
drm/radeon: init pipe setup in kernel code.
drm/radeon: fixup radeon_do_engine_reset
drm/radeon: fix pixcache and purge/cache flushing registers
drm/radeon: write AGP_BASE_2 on chips that support it.
drm/radeon: merge IGP chip setup and fixup RS400 vs RS480 support
drm/radeon: IGP clean up register and magic numbers.
drm/rs690: set base 2 to 0.
drm/rs690: set all of gart base address.
radeon: add production microcode from AMD
drm: pcigart use proper pci map interfaces.
drm: the sg alloc ioctl should write back the handle to userspace
...
This adds missing stolen memory size detect for IGD_GM, be sure to
detect right size as current X intel driver (2.3.2) which has already
worked out.

According to the hw guys, you should use DSTCACHE_CTLSTAT to flush
the 2D dst cache rather than RB2D_DSTCACHE_CTLSTAT.

Texture uploads could hit the blitter coordinate limit, adjust the texture
offset when uploading the pieces. Make sure to check the end address of the
upload too.

This contains all the command buffer processing for the r500 cards.
It doesn't yet contain vblank support.

besides it apparently being useful only in 2.6.24 (the changes in 2.6.25
really mean that it could be converted back to a single-stage mechanism),
I'm seeing an issue in Xen Dom0 kernels, which is caused by the calling
of gart_to_virt() in the second stage invocations of the destroy function.
I think that besides this being a real issue with Xen (where
unmap_page_from_agp() is not just a page table attribute change), this
also is invalid from a theoretical perspective: One should not assume that
gart_to_virt() is still valid after unmapping a page. So minimally (keeping
the 2-stage mechanism) a patch like the one below would be needed.

add a new PCI ID and remove an old dodgy one, include the explaination
in the commented code so nobody readds later.
(davej also sent the pci id addition).

This enforces us to use the drm ioctl types so read/write works correctly and not believe
what userspace tells us.
It does this hopefully without breaking the drm api.

More Kconfig tweaks related to the legacy PC RTC code:
- Describe the legacy PC RTC driver as such ... it's never quite
been clear that this driver is for PC RTCs, and now it's fair
to call this the "legacy" driver.
- Force it to understand about HPET stealing its IRQs ... kernel
code does this always when HPET is in use, there should be no
option for users to goof up the config.
This seems to fix kernel bugzilla #10729.

unicode diacritics support
because that changeset made k_self consider the value as a latin1
character when in Unicode mode, which is wrong; k_self should still take
the console map into account.

Since many distros load this driver by default (throw it against the wall
and see what sticks method). Change the error message severity level to
avoid alarming users. Isn't it annoying when users actually read the
error logs...

Packet sending is driven by two flags, tx_ready and tx_queued.
It was possible, that there were queued data for sending and
hardware was flagged as blocked but in fact it was not.
The tx_queued was indicator but should be really a counter else
first fragmented packet resets tx_queued flag, but there may be
pending packets which do not get sent.
New semantics:
tx_ready - set, if hw is ready to send packet, no packet is being
transferred right now
set the flag right at the place where data are copied
into hw memory and not earlier without checking if it
was succesful
tx_queued - count of enqueued packets, including fragments
