* remotes/riku/tags/pull-linux-user-20160111:
  linux-user/mmap.c: Use end instead of real_end in target_mmap
  linux-user: Add SOCKOP_sendmmsg and SOCKOP_recvmmsg socket call, wire them up.
  linux-user: Update m68k syscall definitions to match Linux 4.4.
  linux-user/syscall.c: Use SOL_SOCKET instead of level for setsockopt()
  linux-user: enable sigaltstack for all architectures
  unicore32: convert get_sp_from_cpustate from macro to inline
  linux-user/mmap.c: Always zero MAP_ANONYMOUS memory in mmap_frag()
  linux-user,sh4: fix signal retcode address
  linux-user: check fd is >= 0 in fd_trans_host_to_target_data/fd_trans_host_to_target_addr
  linux-user: manage bind with a socket of SOCK_PACKET type.
  linux-user: add a function hook to translate sockaddr
  linux-user: rename TargetFdFunc to TargetFdDataFunc, and structure fields accordingly
  linux-user: SOCK_PACKET uses network endian to encode protocol in socket()
  linux-user/syscall.c: malloc()/calloc() to g_malloc()/g_try_malloc()/g_new0()
  linux-user: in poll(), if nfds is 0, pfd can be NULL
  linux-user: correctly align target_epoll_event
  linux-user: add signalfd/signalfd4 syscalls
