Merge commit '3728e6a255b5' into patchwork
* commit '3728e6a255b5': (904 commits) Linux 4.14-rc5 x86/microcode: Do the family check first locking/lockdep: Disable cross-release features for now x86/mm: Flush more aggressively in lazy TLB mode mm, swap: use page-cluster as max window of VMA based swap readahead mm: page_vma_mapped: ensure pmd is loaded with READ_ONCE outside of lock kmemleak: clear stale pointers from task stacks fs/binfmt_misc.c: node could be NULL when evicting inode fs/mpage.c: fix mpage_writepage() for pages with buffers linux/kernel.h: add/correct kernel-doc notation tty: fall back to N_NULL if switching to N_TTY fails during hangup Revert "vmalloc: back off when the current task is killed" mm/cma.c: take __GFP_NOWARN into account in cma_alloc() scripts/kallsyms.c: ignore symbol type 'n' userfaultfd: selftest: exercise -EEXIST only in background transfer mm: only display online cpus of the numa node mm: remove unnecessary WARN_ONCE in page_vma_mapped_walk(). mm/mempolicy: fix NUMA_INTERLEAVE_HIT counter include/linux/of.h: provide of_n_{addr,size}_cells wrappers for !CONFIG_OF mm/madvise.c: add description for MADV_WIPEONFORK and MADV_KEEPONFORK ...
