Merge branch 'akpm' (incoming from Andrew)
Merge second patch-bomb from Andrew Morton: - various misc bits - the rest of MM - add generic fixmap.h, use it - backlight updates - dynamic_debug updates - printk() updates - checkpatch updates - binfmt_elf - ramfs - init/ - autofs4 - drivers/rtc - nilfs - hfsplus - Documentation/ - coredump - procfs - fork - exec - kexec - kdump - partitions - rapidio - rbtree - userns - memstick - w1 - decompressors * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (197 commits) lib/decompress_unlz4.c: always set an error return code on failures romfs: fix returm err while getting inode in fill_super drivers/w1/masters/w1-gpio.c: add strong pullup emulation drivers/memstick/host/rtsx_pci_ms.c: fix ms card data transfer bug userns: relax the posix_acl_valid() checks arch/sh/kernel/dwarf.c: use rbtree postorder iteration helper instead of solution using repeated rb_erase() fs-ext3-use-rbtree-postorder-iteration-helper-instead-of-opencoding-fix fs/ext3: use rbtree postorder iteration helper instead of opencoding fs/jffs2: use rbtree postorder iteration helper instead of opencoding fs/ext4: use rbtree postorder iteration helper instead of opencoding fs/ubifs: use rbtree postorder iteration helper instead of opencoding net/netfilter/ipset/ip_set_hash_netiface.c: use rbtree postorder iteration instead of opencoding rbtree/test: test rbtree_postorder_for_each_entry_safe() rbtree/test: move rb_node to the middle of the test struct rapidio: add modular rapidio core build into powerpc and mips branches partitions/efi: complete documentation of gpt kernel param purpose kdump: add /sys/kernel/vmcoreinfo ABI documentation kdump: fix exported size of vmcoreinfo note kexec: add sysctl to disable kexec_load fs/exec.c: call arch_pick_mmap_layout() only once ...
