Merge branch 'akpm' (final batch from Andrew)
Merge third patch-bumb from Andrew Morton: "This wraps me up for -rc1. - Lots of misc stuff and things which were deferred/missed from patchbombings 1 & 2. - ocfs2 things - lib/scatterlist - hfsplus - fatfs - documentation - signals - procfs - lockdep - coredump - seqfile core - kexec - Tejun's large IDR tree reworkings - ipmi - partitions - nbd - random() things - kfifo - tools/testing/selftests updates - Sasha's large and pointless hlist cleanup" * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (163 commits) hlist: drop the node parameter from iterators kcmp: make it depend on CHECKPOINT_RESTORE selftests: add a simple doc tools/testing/selftests/Makefile: rearrange targets selftests/efivarfs: add create-read test selftests/efivarfs: add empty file creation test selftests: add tests for efivarfs kfifo: fix kfifo_alloc() and kfifo_init() kfifo: move kfifo.c from kernel/ to lib/ arch Kconfig: centralise CONFIG_ARCH_NO_VIRT_TO_BUS w1: add support for DS2413 Dual Channel Addressable Switch memstick: move the dereference below the NULL test drivers/pps/clients/pps-gpio.c: use devm_kzalloc Documentation/DMA-API-HOWTO.txt: fix typo include/linux/eventfd.h: fix incorrect filename is a comment mtd: mtd_stresstest: use prandom_bytes() mtd: mtd_subpagetest: convert to use prandom library mtd: mtd_speedtest: use prandom_bytes mtd: mtd_pagetest: convert to use prandom library mtd: mtd_oobtest: convert to use prandom library ...
