It's still unsure how we will handle DCE 3.1 vs. DCE 3.2, since they have few differences as well. For now separate DCE 2 and DCE 3 path, so we can work on it without a risk of breaking DCE 3.1+.

2014-06-02drm/radeon: add large PTE support for NI, SI and CIK v5Christian König
This patch implements support for VRAM page table entry compression. PTE construction is enhanced to identify physically contiguous page ranges and mark them in the PTE fragment field. L1/L2 TLB support is enabled for 64KB (SI/CIK) and 256KB (NI) PTE fragments, significantly improving TLB utilization for VRAM allocations. Linear store bandwidth is improved from 60GB/s to 125GB/s on Pitcairn. Unigine Heaven 3.0 sees an average improvement from 24.7 to 27.7 FPS on default settings at 1920x1200 resolution with vsync disabled.

2014-06-02locks: ensure that fl_owner is always initialized properly in flock and ↵Jeff Layton
lease codepaths Currently, the fl_owner isn't set for flock locks. Some filesystems use byte-range locks to simulate flock locks and there is a common idiom in those that does: fl->fl_owner = (fl_owner_t)filp; fl->fl_start = 0; fl->fl_end = OFFSET_MAX; Since flock locks are generally "owned" by the open file description, move this into the common flock lock setup code. The fl_start and fl_end fields are already set appropriately, so remove the unneeded setting of that in flock ops in those filesystems as well. Finally, the lease code also sets the fl_owner as if they were owned by the process and not the open file description. This is incorrect as leases have the same ownership semantics as flock locks. Set them the same way. The lease code doesn't actually use the fl_owner value for anything, so this is more for consistency's sake than a bugfix.

2014-06-02intel_pstate: add sample time scalingDirk Brandewie
The PID assumes that samples are of equal time, which for a deferable timers this is not true when the system goes idle. This causes the PID to take a long time to converge to the min P state and depending on the pattern of the idle load can make the P state appear stuck. The hold-off value of three sample times before using the scaling is to give a grace period for applications that have high performance requirements and spend a lot of time idle, The poster child for this behavior is the ffmpeg benchmark in the Phoronix test suite.
