[PATCH] GPU system memory support cache flushing mods.
Made changes necessary in the dfb_surface_buffer_lock function to handle
GPU based reading or writing support for local and system memory based surface
buffers (as well ones in user pre-allocated memory). Previously, when a GPU
read/write was requested, the CPU memory cache was not flushed when the CPU
had only read from the memory. Changes require validation on traditional
non-UMA based graphics drivers.
Updated the dfb_surface_pool_allocate function to alway mark brand new
CoreSurfaceAllocations as having been both read and written to by the CPU.
Updated the allocation_update_copy function to track that the CPU wrote to the
destination buffer allocation and that it read from the source buffer
allocation so that proper cache flushing will occur.
