llmnrd: Poll hostname
Poll "/proc/sys/kernel/hostname" and update the hostname when it was changed. systemd has a similar mechanism. Note that the hostname is not polled if it has been provided on the command line, or if "/proc/sys/kernel/hostname" cannot be opened.

ARC: syscall for userspace cmpxchg assist
Older ARC700 cores (ARC750 specifically) lack instructions to implement atomic r-w-w. This is problematic for userspace libraries such as NPTL which need atomic primitives. So enable them by providing kernel assist. This is costly but really the only sane soluton (othern than tight spinning using the otherwise availiable atomic exchange EX instruciton). Good thing is there are only a few of these cores running Linux out in the wild. This only works on UP systems.
