Merge tag 'v3.18' into drm-next
Linux 3.18 Backmerge Linus tree into -next as we had conflicts in i915/radeon/nouveau, and everyone was solving them individually. * tag 'v3.18': (57 commits) Linux 3.18 watchdog: s3c2410_wdt: Fix the mask bit offset for Exynos7 uapi: fix to export linux/vm_sockets.h i2c: cadence: Set the hardware time-out register to maximum value i2c: davinci: generate STP always when NACK is received ahci: disable MSI on SAMSUNG 0xa800 SSD context_tracking: Restore previous state in schedule_user slab: fix nodeid bounds check for non-contiguous node IDs lib/genalloc.c: export devm_gen_pool_create() for modules mm: fix anon_vma_clone() error treatment mm: fix swapoff hang after page migration and fork fat: fix oops on corrupted vfat fs ipc/sem.c: fully initialize sem_array before making it visible drivers/input/evdev.c: don't kfree() a vmalloc address cxgb4: Fill in supported link mode for SFP modules xen-netfront: Remove BUGs on paged skb data which crosses a page boundary mm/vmpressure.c: fix race in vmpressure_work_fn() mm: frontswap: invalidate expired data on a dup-store failure mm: do not overwrite reserved pages counter at show_mem() drm/radeon: kernel panic in drm_calc_vbltimestamp_from_scanoutpos with 3.18.0-rc6 ...
