[PATCH] uml: clean up address space limits code
I was looking at the code of the UML and more precisely at the functions set_task_sizes_tt and set_task_sizes_skas. I noticed that these 2 functions take a paramater (arg) which is not used : the function is always called with the value 0. I suppose that this value might change in the future (or even can be configured), so I added a constant in mem_user.h file. Also, I rounded CONFIG_HOST_TASk_SIZE to a 4M.
