Hi Linus,

Please pull the 'drm-linus' branch from
ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-linus

Major change is to move the radeon KMS enable out of staging and into 
normal Kconfig land, its not perfect but its as good as userspace was for 
most people.

others:
drm core: just a bogus comment removal
ttm: a few changes one fixes an error printf in reserve_ram_pages_type, 
radeon: Displayport fixes, tested on all the displayport machines I own 
(i.e. 2) but they both now work, r600 blit mutex, AGP warning fix.

vmwgfx: 3 patches for older version of vmware workstation, I think vmware 
have one more patch but since this driver is staging it can wait until 
merge window anyways.

Dave.

    drm/radeon/kms: move radeon KMS on/off switch out of staging.
    
    We are happy enough that the KMS driver is stable enough for enough people
    for the kms enable/disable to leave staging. Distros can now contemplate
    turning this on.

    drm/radeon/kms: Bailout of blit if error happen & protect with mutex V3
    
    If an error happen in r600_blit_prepare_copy report it rather
    than WARNING and keeping execution. For instance if ib allocation
    failed we did just warn about but then latter tried to access
    NULL ib ptr causing oops. This patch also protect r600_copy_blit
    with a mutex as otherwise one process might overwrite blit temporary
    data with new one possibly leading to GPU lockup.
    
    Should partialy or totaly fix:
    https://bugzilla.redhat.com/show_bug.cgi?id=553279
    
    V2 failing blit initialization is not fatal, fallback to memcpy when
    this happen
    V3 init blit before startup as we pin in startup, remove duplicate
    code (this one was actualy tested unlike V2)

    Re-order structure ttm_ref_object to remove 8 bytes of alignment padding
    on 64 bit builds, so shrinking its size from 72 to 64 bytes allowing it
    to fit into a smaller slab.

    drm/kms/radeon: pick digitial encoders smarter. (v3)
    
    booting a Lenovo W500 with LVDS + DP outputs showed up a TODO we had
    on our list, to pick a correct digital encoder block. The LVTMA
    encoder requires the second digital encoder, all others can use any
    encoder at all.
    
    This fixes the digital encoder selection logic to enable LVDS/DP combos
    to work okay.
    
    V2: fix silly addition of connector dig_block and cleanup the other
    places in the code that pick the encoder.
    
    V3: rename to dig_encoder and clean up further - also fix
    the picking algorithm.
    
    tested on Lenovo W500 + desktop 3650 cards.

    drm/radeon/kms: use active device to pick connector for encoder
    
    On the W500 we have UNIPHY routed to both DVI and DP, this seems
    to always pick the DVI connector which means link training fails.
    
    Switch to using active device to pick the connector, this seems
    like it should be safe from a code review, and it fixes things
    a bit more here.
