    uml: clean up TASK_SIZE usage · 42a2b54c

    Clean up the calculation and use of the usable address space size on the host.
    
    task_size is gone, replaced with TASK_SIZE, which is calculated from
    CONFIG_TOP_ADDR.  get_kmem_end and set_task_sizes_skas are also gone.
    
    host_task_size, which refers to the entire address space usable by the UML
    kernel and which may be larger than the address space usable by a UML process,
    since that has to end on a pgdir boundary, is replaced by CONFIG_TOP_ADDR.
    
    STACK_TOP is now TASK_SIZE minus the two stub pages.
