Merge branch 'akpm' (patches from Andrew Morton)

Merge more patches from Andrew Morton:
 "A bunch of fixes.

  Plus Joe's printk move and rework.  It's not a -rc3 thing but now
  would be a nice time to offload it, while things are quiet.  I've been
  sitting on it all for a couple of weeks, no issues"

* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
  vmpressure: make sure there are no events queued after memcg is offlined
  vmpressure: do not check for pending work to prevent from new work
  vmpressure: change vmpressure::sr_lock to spinlock
  printk: rename struct log to struct printk_log
  printk: use pointer for console_cmdline indexing
  printk: move braille console support into separate braille.[ch] files
  printk: add console_cmdline.h
  printk: move to separate directory for easier modification
  drivers/rtc/rtc-twl.c: fix: rtcX/wakealarm attribute isn't created
  mm: zbud: fix condition check on allocation size
  thp, mm: avoid PageUnevictable on active/inactive lru lists
  mm/swap.c: clear PageActive before adding pages onto unevictable list
  arch/x86/platform/ce4100/ce4100.c: include reboot.h
  mm: sched: numa: fix NUMA balancing when !SCHED_DEBUG
  rapidio: fix use after free in rio_unregister_scan()
  .gitignore: ignore *.lz4 files
  MAINTAINERS: dynamic debug: Jason's not there...
  dmi_scan: add comments on dmi_present() and the loop in dmi_scan_machine()
  ocfs2/refcounttree: add the missing NULL check of the return value of find_or_create_page()
  mm: mempolicy: fix mbind_range() && vma_adjust() interaction
