s390/mm: change default addressing mode
Change the default addressing mode so that user space runs in primary space and the kernel runs in home space. In addition remove the "switch_amode" kernel parameter so all users who already specified they want the new default behaviour will stay in the "switched" mode instead of in the opposite they intended. If there is a need to switch addressing modes, this can be done with the "user_mode" kernel parameter: user_mode=home Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
