This fixes 2 bugs:
1. the AGP calculation wasn't consistent with the PCI(E) calc for the
RPTR_ADDR registers. This consolidates the writes and fixes it up.
2. The scratch address was being incorrectly calculated, this breaks
it out into a lot more linear steps.

In compat mode, the cmdbuf->buf 64-bit address cookie can
potentially be only 32-bit aligned. Dereferencing this as
64-bit causes expensive unaligned traps on platforms like
sparc64.
Use get_unaligned() to fix.

This allocates a physical surface for the PCI GART table, this way no
matter what other surface configurations exist the GART table will
always be seen by the hardware properly.
We encode the file pointer of the virtual surface allocate using a
special cookie value, called PCIGART_FILE_PRIV. On the last close, we
release that surface.
Just to be doubly safe, we run the pcigart table setup with the main
surface control register clear.
Based upon ideas from David Airlie and Ben Benjamin Herrenschmidt.

The memory behind ring_rptr can either be in ioremapped memory
or a vmalloc() normal kernel memory buffer.
However, the code unconditionally uses DRM_{READ,WRITE}32() (and thus
readl() and writel()) to access it.
Basically, if RADEON_IS_AGP then it's ioremap()'d memory else it's
vmalloc'd memory.
Adjust all of the ring_rptr access code as needed.
While we're here, kill the 'scratch' pointer in drm_radeon_private.
It's only used in the one place where it is initialized.

The kernel shouldn't be in the business of telling user space which
driver to load. The kernel defers mapping PCI IDs to module names
to user space and we should do the same for DRI drivers.
And in fact, that's how it does work today. Nothing uses the
dri_library_name attribute, and the attribute is in fact broken.
For intel devices, it falls back to the default behaviour of returning
the kernel module name as the DRI driver name, which doesn't work for
i965 devices. Nobody has ever hit this problem or filed a bug about this.

This changes drm_local_map to use a resource_size for its "offset"
member instead of an unsigned long, thus allowing 32-bit machines
with a >32-bit physical address space to be able to store there
their register or framebuffer addresses when those are above 4G,
such as when using a PCI video card on a recent AMCC 440 SoC.
This patch isn't as "trivial" as it sounds: A few functions needed
to have some unsigned long/int changed to resource_size_t and a few
printk's had to be adjusted.
But also, because userspace isn't capable of passing such offsets,
I had to modify drm_find_matching_map() to ignore the offset passed
in for maps of type _DRM_FRAMEBUFFER or _DRM_REGISTERS.
If we ever support multiple _DRM_FRAMEBUFFER or _DRM_REGISTERS maps
for a given device, we might have to change that trick, but I don't
think that happens on any current driver.

The DRM uses its own wrappers to obtain resources from PCI devices,
which currently convert the resource_size_t into an unsigned long.
This is broken on 32-bit platforms with >32-bit physical address
space.
This fixes them, along with a few occurences of unsigned long used
to store such a resource in drivers.

This is step one towards having multiple masters sharing a drm
device in order to get fast-user-switching to work.
It splits out the information associated with the drm master
into a separate kref counted structure, and allocates this when
a master opens the device node. It also allows the current master
to abdicate (say while VT switched), and a new master to take over
the hardware.
It moves the Intel and radeon drivers to using the sarea from
within the new master structures.

Now that the radeon driver has suspend/resume functions, it needs to map its
registers at load time or it will likely crash if a suspend operation occurs
before the driver has been initialized.
This patch moves the register mapping code from firstopen to load and makes
the mapping into a _DRM_DRIVER one so that the core won't remove it at
lastclose time.
Fixes (at least partially) kernel bz #11891.

Previously, drivers supporting vblank interrupt waits would run the interrupt
all the time, or all the time that any 3d client was running, preventing the
CPU from sleeping for long when the system was otherwise idle. Now, interrupts
are disabled any time that no client is waiting on a vblank event. The new
method uses vblank counters on the chipsets when the interrupts are turned
off, rather than counting interrupts, so that we can continue to present
accurate vblank numbers.

radeon: fix some hard lockups on r3/4/500s

This makes our handling of cliprects sane. drm_clip_rect always has exclusiv
bottom-right corners, but the hardware expects inclusive bottom-right corner
so we adjust this here.
This complements Michel Daenzer's commit 57aea290e1e0a26d1e74df6cff777eb9f03
