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
