Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 update from Martin Schwidefsky: "The most prominent change in this patch set is the software dirty bit patch for s390. It removes __HAVE_ARCH_PAGE_TEST_AND_CLEAR_DIRTY and the page_test_and_clear_dirty primitive which makes the common memory management code a bit less obscure. Heiko fixed most of the PCI related fallout, more often than not missing GENERIC_HARDIRQS dependencies. Notable is one of the 3270 patches which adds an export to tty_io to be able to resize a tty. The rest is the usual bunch of cleanups and bug fixes." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (42 commits) s390/module: Add missing R_390_NONE relocation type drivers/gpio: add missing GENERIC_HARDIRQ dependency drivers/input: add couple of missing GENERIC_HARDIRQS dependencies s390/cleanup: rename SPP to LPP s390/mm: implement software dirty bits s390/mm: Fix crst upgrade of mmap with MAP_FIXED s390/linker skript: discard exit.data at runtime drivers/media: add missing GENERIC_HARDIRQS dependency s390/bpf,jit: add vlan tag support drivers/net,AT91RM9200: add missing GENERIC_HARDIRQS dependency iucv: fix kernel panic at reboot s390/Kconfig: sort list of arch selected config options phylib: remove !S390 dependeny from Kconfig uio: remove !S390 dependency from Kconfig dasd: fix sysfs cleanup in dasd_generic_remove s390/pci: fix hotplug module init s390/pci: cleanup clp page allocation s390/pci: cleanup clp inline assembly s390/perf: cpum_cf: fallback to software sampling events s390/mm: provide PAGE_SHARED define ...
