[intel-GEM] Clean up GEM ioctl naming.
...
Rename 'validate_entry' to 'exec_object', then clean up some field names in
structures (renaming buffer_offset to just offset, for example).

GEM: Fix arguments to drm_memrange_init so we don't exceed our allocation.
...
It takes (offset, size), not (offset, end).

GEM: Separate the LRU into execution list and LRU list.
...
Now, the LRU list has objects that are completely done rendering and ready
to kick out, while the execution list has things with active rendering,
which have associated cookies and reference counts on them.

Clean up whinging from checkpatch.pl in drm_gem.c

[intel-gem] Move domains to relocation records. add set_domain ioctl.
...
Domain information is about buffer relationships, not buffer contents. That
means a relocation contains the domain information as it knows how the
source buffer references the target buffer.
This also adds the set_domain ioctl so that user space can move buffers to
the cpu domain.

Apply a few stylistic cleanups to match kernel code.

GEM: Wait for existing rendering to complete before writing relocation data.
...
This should already have been generally safe since we don't change contents
and put in new relocations between execbufs, so if we were writing in a new
relocation then we'd already waited rendering to complete when we moved
the target of the relocation. However, doing the right thing will be required
if we do buffer reuse.

GEM: Extend cache domain stuff for 965.
...
One of our MI_FLUSH bits is reserved on 965, being always implied, and there's
a vertex cache that was forgotten.

[intel-GEM] ref count objects in gtt-lru.
...
If objects on the lru aren't ref counted, they'll get pulled from the gtt as
soon as they are freed. This change does cause objects to get stuck in the
gtt until they're forced out by new requests. The lru should get cleaned
when the irq occurs.

[intel-GEM] Add memory domain support.
...
Memory domains allow the kernel to track which caches to flush and how to
move objects before buffer execution.

Unlock pages right after getting them.
...
pages come back from find_or_create_page locked, but must not stay locked
for long. Unlock them immediately instead of waiting until we're done with
them to avoid deadlock when applications try to touch them.

Initialize device gem data.
return -ENODEV for gem ioctls if the driver doesn't support gem.

Add name/open ioctls, separate handle and pointer ref counts.
...
Names are just another unique integer set (from another idr object).
Names are removed when the user refernces (handles) are all destroyed --
this required that handles for objects be counted separately from
internal kernel references (so that we can tell when the handles are all
gone).

Fix gem ioctls to be 32/64-bit clean.
...
mixed 32/64 bit systems need 'special' help for ioctl where the user-space
and kernel-space datatypes differ. Fixing the datatypes to be the same size,
and align the same way for both 32 and 64-bit ppc and x86 environments will
elimiante the need to have magic 32/64-bit ioctl translation code.
