Merge tag 'v4.7-rc2' into v4l_for_linus
Linux 4.7-rc2 * tag 'v4.7-rc2': (10914 commits) Linux 4.7-rc2 devpts: Make each mount of devpts an independent filesystem. parisc: Move die_if_kernel() prototype into traps.h header parisc: Fix pagefault crash in unaligned __get_user() call parisc: Fix printk time during boot parisc: Fix backtrace on PA-RISC mm, page_alloc: recalculate the preferred zoneref if the context can ignore memory policies mm, page_alloc: reset zonelist iterator after resetting fair zone allocation policy mm, oom_reaper: do not use siglock in try_oom_reaper() mm, page_alloc: prevent infinite loop in buffered_rmqueue() checkpatch: reduce git commit description style false positives mm/z3fold.c: avoid modifying HEADLESS page and minor cleanup memcg: add RCU locking around css_for_each_descendant_pre() in memcg_offline_kmem() mm: check the return value of lookup_page_ext for all call sites kdump: fix dmesg gdbmacro to work with record based printk mm: fix overflow in vm_map_ram() Btrfs: deal with duplciates during extent_map insertion in btrfs_get_extent arm64: fix alignment when RANDOMIZE_TEXT_OFFSET is enabled arm64: move {PAGE,CONT}_SHIFT into Kconfig arm64: mm: dump: log span level ...
