s390/mm: rename addressing_mode to s390_user_mode
Renaming the globally visible variable "user_mode" to "addressing_mode" in order to fix a name clash was not a good idea. (Commit 37fe1d73 "s390/mm: rename user_mode variable to addressing_mode") Looking at the code after a couple of weeks one thinks: addressing mode of what? So rename the variable again. This time to s390_user_mode. Which hopefully makes more sense. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
