Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull second set of s390 patches from Martin Schwidefsky: "The main part of this merge are Heikos uaccess patches. Together with commit 09884964335e ("mm: do not grow the stack vma just because of an overrun on preceding vma") the user string access is hopefully fixed for good. In addition some bug fixes and two cleanup patches." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/module: fix compile warning qdio: remove unused parameters s390/uaccess: fix kernel ds access for page table walk s390/uaccess: fix strncpy_from_user string length check input: disable i8042 PC Keyboard controller for s390 s390/dis: Fix invalid array size s390/uaccess: remove pointless access_ok() checks s390/uaccess: fix strncpy_from_user/strnlen_user zero maxlen case s390/uaccess: shorten strncpy_from_user/strnlen_user s390/dasd: fix unresponsive device after all channel paths were lost s390/mm: ignore change bit for vmemmap s390/page table dumper: add support for change-recording override bit
