* riku/linux-user-for-upstream:
linux-user: Do not ignore mmap failure from host
linux-user: improve target_to_host_sock_type conversion
user-exec.c: Set is_write correctly in the ARM cpu_signal_handler()
linux-user: Fix sys_utimensat (would not compile on old glibc)
linux-user: fix signal number range check
linux-user: add SIOCADDRT/SIOCDELRT support
linux-user: handle /proc/$$ like /proc/self
