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
