video: tegra: dc: use nvhost driver for host1x power management
Incrementing the frame done syncpoint value from the display interrupt
requires that the host module is powered on. As the syncpoint state is
saved and restored automatically by the host driver a cpu increment of
a syncpoint in the powered down state will be lost.
Also adds checks for host module being powered.

tegra user-space graphics drivers may allocate framebuffers using
nvmap rather than rendering to the common framebuffer, this may
be done to support deeper buffer pipelining, color formats
and pixel layouts other than the initial bootup framebuffer,
etc.
to use this ioctl, a caller must first specify an nvmap fd
which is already open in the calling process so that the
subsequent flip ioctls may be properly validated. flips are performed
asynchronously, with flip completion notifications provided back to
the caller via the host1x syncpoint mechanism

video: tegra: host1x driver
the graphics and display hardware on tegra SoCs is accessed
through a command DMA front-end called host1x
host driver clients place commands into memory objects called
streams, and submit a stream on one of 8 channels: the assignment
of streams-to-channels depends on the hardware module(s) programmed
by the stream: for example, all streams which program the 3D
hardware are submitted on channel 1.
the host1x hardware includes two synchronization primitives to
allow command streams to synchronize access to memory or to
hardware engines shared across channels (e.g. the 2D blitter):
sync points and module mutexes. both primitives can also be
used to synchronize with the CPU.
the host1x driver performs power management for all modules
behind the host block: once a module is idle (i.e., the
last stream which accesses it has completed, indicated by
a syncpoint) and has remained idle for an extended period
of time, the module's clock (and power gate island, if the
module is uniquely power-gated) is disabled, and will be
automatically re-enabled when a new stream is submitted for
that module.

video: tegra: add GPU memory management driver (nvmap)
nvmap provides an interface for user- and kernel-space clients to
allocate and access memory "handles" which can be pinned to enable
the memory to be shared with DMA devices on the system, and may
also be mapped (using caller-specified cache attributes) so that
they are directly accessible by the CPU.
the memory handle object gives clients a common API to allocate from
multiple types of memory: platform-reserved physically contiguous
"carveout" memory, physically contiguous (order > 0) OS pages,
or physically discontiguous order-0 OS pages that can be remapped
into a contiguous region of the DMA device's virtual address space
through the tegra IOVMM subsystem.
unpinned and unmapped memory handles are relocatable at run-time
by the nvmap system. handles may also be shared between multiple
clients, allowing (for example) a window manager and its client
applications to directly share framebuffers

[ARM] mm: change to read-allocate as default SMP cache policy
the "streaming" mode optimization which skips cacheline allocation
for fully-dirty lines is frequently defeated when coherent processors
perfom stores simultaneously
this results in cachelines being allocated in SMP which are not
allocated when run in uniprocessor, resulting in a significant
reduction in aggregate write bandwidth. for example, on Tegra 2
systems with 300MHz DDR main memory, running memset over a large
buffer (i.e., L2 miss) on a single processor will achieve ~2GB/sec
of write bandwidth, but if the same operation is run in parallel on
both CPUs, the aggregate write bandwidth is just 500MB/sec

of this performance loss on SMP systems.

[ARM] mm: add page allocator for modifying cache attributes
ARM CPUs with speculative prefetching have undefined behaviors when the
same physical page is mapped to two different virtual addresses with
conflicting cache attributes.
since many recent systems include IOMMU functionality (i.e., remapping
of discontiguous physical pages into a virtually-contiguous address
range for I/O devices), it is desirable to support allocating any
available OS memory for use by the I/O devices. however, since many
systems do not support cache coherency between the CPU and DMA devices,
these devices are left with using DMA-coherent allocations from the OS
(which severely limits the benefit of an IOMMU) or performing cache
maintenance (which can be a severe performance loss, particularly on
systems with outer caches, compared to using DMA-coherent memory).
this change adds an API for allocating pages from the OS with specific
cache maintenance properties and ensures that the kernel's mapping
of the page reflects the desired cache attributes, in line with the
ARMv7 architectural requirements

nvmap and nvhost will behave improperly if iovmm is not present when
their respective devices are probed; however, the probe ordering depends

iovmm-gart into subsys_initcall to ensure that it is registered earlier
than other drivers
