While there is still performance work to be done (particularly
surrounding RCL generation), the CL submit ABI should be settled and
done now.

Eric Anholt d5b1a78a77 drm/vc4: Add support for drawing 3D frames.
The user submission is basically a pointer to a command list and a
pointer to uniforms.  We copy those in to the kernel, validate and
relocate them, and store the result in a GPU BO which we queue for
execution.

v2: Drop support for NV shader recs (not necessary for GL), simplify
    vc4_use_bo(), improve bin flush/semaphore checks, use __u32 style
    types.

Eric Anholt 463873d570 drm/vc4: Add an API for creating GPU shaders in GEM BOs.
Since we have no MMU, the kernel needs to validate that the submitted
shader code won't make any accesses to memory that the user doesn't
control, which involves banning some operations (general purpose DMA
writes), and tracking where we need to write out pointers for other
operations (texture sampling).  Once it's validated, we return a GEM
BO containing the shader, which doesn't allow mapping for write or
exporting to other subsystems.

v2: Use __u32-style types.

Eric Anholt d5bc60f6ad drm/vc4: Add create and map BO ioctls.
While there exist dumb APIs for creating and mapping BOs, one of the
rules is that drivers doing 3D acceleration have to provide their own
APIs for buffer allocation (besides, the pitch/height parameters of
the dumb alloc don't really make sense for a lot of 3D allocations).

v2: Use __u32-style types, use "drm.h" instead of <drm/drm.h>.

Ville Syrjälä 8697600b40 drm/i915: Make the high dword offset more explicit in i915_reg_read_ioctl
Store the upper dword of the register offset in the whitelist as well.
This would allow it to read register where the two halves aren't sitting
right next to each other, and it'll make it easier to make register
access type safe.

While at it change the register offsets to u32 from u64. Our register
space isn't quite that big, yet :)

v2: Use ldw/udw as the suffixes, and add a note about
    64bit wide split regs (Chris)

Linus Torvalds b44a3d2a85 ARM: SoC driver updates for v4.4
As we've enabled multiplatform kernels on ARM, and greatly done away with
 the contents under arch/arm/mach-*, there's still need for SoC-related
 drivers to go somewhere.
 
 Many of them go in through other driver trees, but we still have
 drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
 that might be shared between ARM and ARM64 (or just in general makes
 sense to not have under the architecture directory).
 
 This branch contains mostly such code:
 
 - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate
   with power management blocks on these SoCs for use by clock, regulator and
   bus frequency drivers.
 - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs.
 - Drivers for ARM's SCPI (System Control Processor). Not to be confused with
   PSCI (Power State Coordination Interface). SCPI is used to communicate with
   the assistant embedded cores doing power management, and we have yet to see
   how many of them will implement this for their hardware vs abstracting in
   other ways (or not at all like in the past).
 - To make confusion between SCPI and PSCI more likely, this release also
   includes an update of PSCI to interface version 1.0.
 - Rockchip support for power domains.
 - A driver to talk to the firmware on Raspberry Pi.

Linus Torvalds 27eb427bdc Merge branch 'for-linus-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs updates from Chris Mason:
 "We have a lot of subvolume quota improvements in here, along with big
  piles of cleanups from Dave Sterba and Anand Jain and others.

  Josef pitched in a batch of allocator fixes based on production use
  here at FB.  We found that mount -o ssd_spread greatly improved our
  performance on hardware raid5/6, but it exposed some CPU bottlenecks
  in the allocator.  These patches make a huge difference"

Linus Torvalds 7130098096 Add support for the CSUM_SEED feature which will allow future
userspace utilities to change the file system's UUID without rewriting
 all of the file system metadata.
 
 A number of miscellaneous fixes, the most significant of which are in
 the ext4 encryption support.  Anyone wishing to use the encryption
 feature should backport all of the ext4 crypto patches up to 4.4 to
 get fixes to a memory leak and file system corruption bug.
 
 There are also cleanups in ext4's feature test macros and in ext4's
 sysfs support code.
