Merge branch 'akpm' (patches from Andrew)
Merge misc fixes from Andrew Morton:
"15 fixes"
[ This does not merge the "fortify: use WARN instead of BUG for now"

configurations. Arnd is on it. - Linus ]

ipc: add missing container_of()s for randstruct
cpuset: fix a deadlock due to incomplete patching of cpusets_enabled()
userfaultfd_zeropage: return -ENOSPC in case mm has gone
mm: take memory hotplug lock within numa_zonelist_order_handler()
mm/page_io.c: fix oops during block io poll in swapin path
zram: do not free pool->size_class
kthread: fix documentation build warning
