Merge branch 'akpm' (patches from Andrew)
Merge fixes from Andrew Morton: "14 fixes" * emailed patches from Andrew Morton <akpm@linux-foundation.org>: rapidio/tsi721: fix incorrect detection of address translation condition rapidio/documentation/mport_cdev: add missing parameter description kernel/fork: fix CLONE_CHILD_CLEARTID regression in nscd MAINTAINERS: Vladimir has moved mm, mempolicy: task->mempolicy must be NULL before dropping final reference printk/nmi: avoid direct printk()-s from __printk_nmi_flush() treewide: remove references to the now unnecessary DEFINE_PCI_DEVICE_TABLE drivers/scsi/wd719x.c: remove last declaration using DEFINE_PCI_DEVICE_TABLE mm, vmscan: only allocate and reclaim from zones with pages managed by the buddy allocator lib/test_hash.c: fix warning in preprocessor symbol evaluation lib/test_hash.c: fix warning in two-dimensional array init kconfig: tinyconfig: provide whole choice blocks to avoid warnings kexec: fix double-free when failing to relocate the purgatory mm, oom: prevent premature OOM killer invocation for high order request
