We have it, so use it. This required moving the function to avoid
a forward declaration.

The fence_list should be lru ordered for otherwise we might try
to steal a fence reg from an active object even though there are
fences from inactive objects available. lru ordering was obeyed
for gpu access everywhere save when moving dirty objects from
flushing_list to active_list.
Fixing this cause the code to indent way to much, so I've extracted
the flushing_list processing logic into its on function.

The spaghetti logic in there tripped up my brain's code parser for a
few secs. Prevent this from happening again by extracting the fence
stealing code into a seperate functions. IMHO this slightly clears up
the code flow.
v2: Beautified according to ickle's comments.
v3: ickle forgot to flush his comment queue ... Now there's also a
we-are-paranoid BUG_ON in there.
v4: I've forgotten to switch on my brain when doing v3. Now the BUG_ON
actually checks something useful.
v5: Clean up a stale comment as noted by Eric Anholt.

This has a few functional changes against the old code:
* a few more unnecessary loads and stores to the drm_i915_fence_reg
objects. Also an unnecessary store to the hw fence register.
* zaps any userspace mappings before doing other flushes. Only changes
anything when userspace does racy stuff against itself.
* also flush GTT domain. This is a noop, but still try to keep the
bookkeeping correct.

See http://bugzilla.kernel.org/show_bug.cgi?id=15021
Make sure that the appropriate AGP module is loaded and probed before
trying to set up the DRM. The DRM already depends on the AGP core,
but in this case we know the specific AGP driver we need too, and can
help users avoid the trap of loading the AGP driver after the DRM
driver.

The netif_wake_queue() is called correctly (i.e. only on !txfull
condition) from txdone routine. So Unconditional call to the
netif_wake_queue() here is wrong. This might cause calling of
start_xmit routine on txfull state and trigger BUG_ON.
This bug does not happen when NAPI disabled. After txdone there
must be at least one free tx slot. But with NAPI, this is not
true anymore and the BUG_ON can hits on heavy load.
In this driver NAPI was enabled on 2.6.33-rc1 so this is
regression from 2.6.32 kernel.

Check for error return from pci_map_single/pci_map_page and clean up.
With this and the previous patch the driver was able to handle a significant

download large files at a reasonable speed).

geode-mfgpt: restore previous behavior for selecting IRQ
The MFGPT IRQ used to be, in order of decreasing priority,
* IRQ supplied by the user as a boot-time parameter,
* IRQ previously set by the BIOS or another driver,
* default IRQ given at compile time.
Return to this behavior, which got broken when splitting the
MFGPT/clocksource driver for 2.6.33-rc1.

This commit changes nouveau to construct PTEs which look very much like
the ones the binary driver creates.
I presume that filling multiple PTEs identically with length flags and
the physical address of the start of a block of VRAM is a hint to the
memory controller that it need not perform additional page table lookups
for that range of addresses.
