Make sure the context is intact when the events are canceled. Since
the timestamps are now per-context, readtimestamp requires a valid
context.

The 2d timestamp is used as an index into the ringbuffer.
Now that z180_dev->current_timestamp is preserved across
resume, make sure that ADDR_VGV3_NEXTADDR is set to the
gpu address that corresponds to the current timestamp.

Sometimes, the userspace driver has a need to disable some of the
power savings features in the kernel for a brief period. Add a
property to control nap and DCVS from the user space driver via
KGSL_IOCTL_SETPROPERTY.

The multimedia firmware on 8960 will always be
loaded into a fixed address, and all callers into
this firmware must be no more than 256M above the
start of this firmware.
This implies that the the mm ION heap and its associated heaps
(mm_fw and mfc) must also be created in a fixed place.
This version of the patch keeps the mm fw heap size
to 2M for compatibility with the current tip. This
will eventually be reduced to 1M.

struct kgsl_memregion was used to store the MMIO and GMEM
addressing for KGSL and adreno but it didn't serve much
purpose other than another level of redirection in the
structures. Remove it and add the necessary pointer and
size members directly to the KGSL and adreno structs.

Record the last issued timestamp for each context in the snapshot.
With per context timestamps, each context has its own timestamp
sequence so it is important to know the last timestamp issued by
the context so we can reconstruct the failing frame in the snapshot
output.

If an ion allocation fails because of memory fragmentation a debug
message should be printed. However, the logic that decides whether
the debug message should be printed or not is incorrect causing
the debug message to not be printed when it should.

The existing timestamp_cmp function returns a different
result depending on the order of the input parameters due to
having an asymetric valid window. When no rollover is
detected the window is 2^31 but when a rollover is detected
the window is 25000. This change makes the rollover window
symmetric at 2^31.

Move the call for creating the ion client from kgsl_setup_ion to
kgsl_device_platform_probe. Keeping the create ion client call linked to
kgsl_ioctl_map_user_mem made the user process which first used this
ioctl be forever visible as an ion client in debugfs, even when the
process itself had terminated. Creating ion client in probe ensures that
kgsl appears as the ion client in debugfs and avoids confusion.

The IBs stored by legacy context switch are not stored as part of the
nominal mem_entry accounting that the rest of the process has. As a
result we cannot freeze the legacy context switch IBs for dump. Instead,
dump them into the snapshot as IB sections. Also, store the offset for
the frozen objects to avoid trying to read the gpuaddr of the memdesc after
it had been freed.
