s390/mm: make TASK_SIZE independent from the number of page table levels
The TASK_SIZE for a process should be maximum possible size of the address space, 2GB for a 31-bit process and 8PB for a 64-bit process. The number of page table levels required for a given memory layout is a consequence of the mapped memory areas and their location. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
