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
