Currently the videomemory is allocated by kmalloc, making it a memory region that is not necessarily page aligend. This leads to problems upon mmap call, where the video memory's address gets aligned to the next page boundary. The result is that the userspace program that issued the mmap call is not able to access the video memory from the start to the next page boundary. This patch changes the allocation of the video memory to use __get_free_pages() in order to obtain memory that is aligned to page boundaries.
