Merge branch 'akpm' (patches from Andrew)
Merge yet more updates from Andrew Morton: - Oleg's "wait/ptrace: assume __WALL if the child is traced". It's a kernel-based workaround for existing userspace issues. - A few hotfixes - befs cleanups - nilfs2 updates - sys_wait() changes - kexec updates - kdump - scripts/gdb updates - the last of the MM queue - a few other misc things * emailed patches from Andrew Morton <[email protected]>: (84 commits) kgdb: depends on VT drm/amdgpu: make amdgpu_mn_get wait for mmap_sem killable drm/radeon: make radeon_mn_get wait for mmap_sem killable drm/i915: make i915_gem_mmap_ioctl wait for mmap_sem killable uprobes: wait for mmap_sem for write killable prctl: make PR_SET_THP_DISABLE wait for mmap_sem killable exec: make exec path waiting for mmap_sem killable aio: make aio_setup_ring killable coredump: make coredump_wait wait for mmap_sem for write killable vdso: make arch_setup_additional_pages wait for mmap_sem for write killable ipc, shm: make shmem attach/detach wait for mmap_sem killable mm, fork: make dup_mmap wait for mmap_sem for write killable mm, proc: make clear_refs killable mm: make vm_brk killable mm, elf: handle vm_brk error mm, aout: handle vm_brk failures mm: make vm_munmap killable mm: make vm_mmap killable mm: make mmap_sem for write waits killable for mm syscalls MAINTAINERS: add co-maintainer for scripts/gdb ...
