Pull drm zpos property support from Dave Airlie:
 "This tree was waiting on some media stuff I hadn't had time to get a
  stable branchpoint off, so I just waited until it was all in your tree
  first.

  It's been around a bit on the list and shouldn't affect anything
  outside adding the generic API and moving some ARM drivers to using
  it"

<title>dma-mapping: use unsigned long for dma_attrs</title>

<id>urn:sha1:00085f1efa387a8ce100e3734920f7639c80caa3</id>
<content type='text'>
The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer.  Thus the pointer can point to const data.
However the attributes do not have to be a bitfield.  Instead unsigned
long will do fine:

1. This is just simpler.  Both in terms of reading the code and setting
   attributes.  Instead of initializing local attributes on the stack
   and passing pointer to it to dma_set_attr(), just set the bits.

2. It brings safeness and checking for const correctness because the
   attributes are passed by value.

<content type='text'>
This clearly had never gotten tested, probably because you need a fairly
minimal configuration in order to disable DEBUG_FS (several other
options select it).

The dummy inline functions that were used for the no-DEBUG_FS case were
missing the argument names in the declarations.

Fixes: 1dac891c1c95 ("drm/i915: Register debugfs interface last")

Bspec says:
"Restriction : SRD must not be enabled when the PSR Setup time from DPCD
00071h is greater than the time for vertical blank minus one line."

Let's check for that and disallow PSR if we exceed the limit.

Add a small helper to parse the PSR setup time from the DPCD PSR
capabilities and return the value in microseconds.
