Merge branch 'akpm' (patches from Andrew)
Pull updates from Andrew Morton: "Most of -mm and quite a number of other subsystems: hotfixes, scripts, ocfs2, misc, lib, binfmt, init, reiserfs, exec, dma-mapping, kcov. MM is fairly quiet this time. Holidays, I assume" * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (118 commits) kcov: ignore fault-inject and stacktrace include/linux/io-mapping.h-mapping: use PHYS_PFN() macro in io_mapping_map_atomic_wc() execve: warn if process starts with executable stack reiserfs: prevent NULL pointer dereference in reiserfs_insert_item() init/main.c: fix misleading "This architecture does not have kernel memory protection" message init/main.c: fix quoted value handling in unknown_bootoption init/main.c: remove unnecessary repair_env_string in do_initcall_level init/main.c: log arguments and environment passed to init fs/binfmt_elf.c: coredump: allow process with empty address space to coredump fs/binfmt_elf.c: coredump: delete duplicated overflow check fs/binfmt_elf.c: coredump: allocate core ELF header on stack fs/binfmt_elf.c: make BAD_ADDR() unlikely fs/binfmt_elf.c: better codegen around current->mm fs/binfmt_elf.c: don't copy ELF header around fs/binfmt_elf.c: fix ->start_code calculation fs/binfmt_elf.c: smaller code generation around auxv vector fill lib/find_bit.c: uninline helper _find_next_bit() lib/find_bit.c: join _find_next_bit{_le} uapi: rename ext2_swab() to swab() and share globally in swab.h lib/scatterlist.c: adjust indentation in __sg_alloc_table ...
