When activating CONFIG_THREAD_INFO_IN_TASK, linux/sched.h includes asm/current.h. This generates a circular dependency. To avoid that, asm/processor.h shall not be included in mmu-hash.h. In order to do that, this patch moves into a new header called asm/task_size_64/32.h all the TASK_SIZE related constants, which can then be included in mmu-hash.h directly.
