Merge branch 'akpm' (patches from Andrew)
Merge misc fixes from Andrew Morton:
"11 fixes"
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
kasan: do not sanitize kexec purgatory
drivers/rapidio/devices/tsi721.c: make module parameter variable name unique
mm/hugetlb.c: don't call region_abort if region_chg fails
kasan: report only the first error by default
hugetlbfs: initialize shared policy as part of inode allocation
mm: fix section name for .data..ro_after_init
mm, hugetlb: use pte_present() instead of pmd_present() in follow_huge_pmd()
mm: workingset: fix premature shadow node shrinking with cgroups
mm: rmap: fix huge file mmap accounting in the memcg stats
mm: move mm_percpu_wq initialization earlier
mm: migrate: fix remove_migration_pte() for ksm pages
