3da1f33e79 drm: Prefix info printk about registering panic notifier with 'drm'
Recently I've studied my system dmesg and seen this:

  <lots of stuff before>
1 [    0.478416] ACPI: Battery Slot [C1B4] (battery present)
2 [    0.478648] ACPI: Battery Slot [C1B3] (battery absent)
3 [    0.906678] [drm] initialized overlay support
4 [    1.762304] Console: switching to colour frame buffer device 128x48
5 [    1.765211] fb0: inteldrmfb frame buffer device
6 [    1.765242] registered panic notifier
7 [    1.765272] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0
8 [    1.765372] Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled
  <lots of stuff after>

and it was not evident who registered that panic notifier on line 6.

I'd bought it as some low-level stuff needed by kernel itself, but the
time was inappropriate -- too late for such things.

So I had to study sources to see it was drm who was registering
switch-to-fb on panic.

Let's avoid possible confusion and mark this message as going from drm
subsystem.

(I'm a bit unsure whether to use '[drm]:' or 'drm:' -- the rest of the
 kernel just uses 'topic:', and even in drm_fb_helper.c we use 'fb%d:'
 without [] brackets. Either way is ok with me.)

a1e9ada3e1 drm/radeon/kms: R3XX-R4XX fix GPU reset code
Previous reset code leaded to computer hard lockup (need to unplug
the power too reboot the computer) on various configuration. This
patch change the reset code to avoid hard lockup. The GPU reset
is failing most of the time but at least user can log in remotely
or properly shutdown the computer.

Two issues were leading to hard lockup :
- Writting to the scratch register lead to hard lockup most likely
because the write back mecanism is in fuzy state after GPU lockup.
- Resetting the GPU memory controller and not reinitializing it
after leaded to hard lockup. We did only reinitialize in case of
successfull reset thus unsuccessfull reset quickly leaded to hard
lockup.

82c5da6bf8 drm/ttm: ttm_fault callback to allow driver to handle bo placement V6
On fault the driver is given the opportunity to perform any operation
it sees fit in order to place the buffer into a CPU visible area of
memory. This patch doesn't break TTM users, nouveau, vmwgfx and radeon
should keep working properly. Future patch will take advantage of this
infrastructure and remove the old path from TTM once driver are
converted.

V2 return VM_FAULT_NOPAGE if callback return -EBUSY or -ERESTARTSYS
V3 balance io_mem_reserve and io_mem_free call, fault_reserve_notify
   is responsible to perform any necessary task for mapping to succeed
V4 minor cleanup, atomic_t -> bool as member is protected by reserve
   mecanism from concurent access
V5 the callback is now responsible for iomapping the bo and providing
   a virtual address this simplify TTM and will allow to get rid of
   TTM_MEMTYPE_FLAG_NEEDS_IOREMAP
V6 use the bus addr data to decide to ioremap or this isn't needed
   but we don't necesarily need to ioremap in the callback but still
   allow driver to use static mapping

08d075116d drm/radeon/kms: fix tv dac conflict resolver
On systems with the tv dac shared between DVI and TV,
we can only use the dac for one of the connectors.
However, when using a digital monitor on the DVI port,
you can use the dac for the TV connector just fine.
Check the use_digital status when resolving the conflict.

Fixes fdo bug 27649, possibly others.

Typo in in flush leaded to no flush of the RS600 tlb which
ultimately leaded to massive system ram corruption, with
this patch everythings seems to work properly.

7f8a85698f drm/i915: Add the support of memory self-refresh on Ironlake
Update the self-refresh watermark for display plane/cursor and enable
the memory self-refresh on Ironlake. The watermark is also updated for
the active display plane.

More than 1W idle power is saved on one Ironlake laptop after enabling
memory self-refresh.

d4294342fd drm/i915: Move Pineview CxSR and watermark code into update_wm hook.
Previously, after setting up the Pineview CxSR state, i9xx_update_wm would
get called and overwrite our state.

BTW: We will disable the self-refresh and never enable it any more if we
can't find the appropriate the latency on pineview plaftorm. In such case
the update_wm callback will be NULL.

The bitmask macro is also defined to access the corresponding fifo
watermark register.
