Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 patches from Martin Schwidefsky:
"Some more bug fixes and a config change.
The signal bug is nasty, if the clock_gettime vdso function is
interrupted by a signal while in access-register-mode we end up with
an endless signal loop until the signal stack is full. The config
change is for aligned struct pages, gives us 8% improvement with
hackbench."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390/3215: fix tty close handling
s390/mm: have 16 byte aligned struct pages
s390/gup: fix access_ok() usage in __get_user_pages_fast()
s390/gup: add missing TASK_SIZE check to get_user_pages_fast()
s390/topology: fix core id vs physical package id mix-up
s390/signal: set correct address space control
