2016-02-24erts: Make erlang:halt() accept bignums as StatusSverker Eriksson
Just mask away the high bits to get a more tolerant erlang:halt that behaves the same on 32 and 64 bit architectures.
2016-02-10epmd: support IPv6 node registrationMichael Santos
Allow IPv6 nodes to register with and query epmd. On systems with IPv6 support: * epmd listens on both the IPv4 and IPv6 ANY or loopback sockets * the epmd cli client connects to epmd over the IPv6 loopback * distributed nodes started with "-proto_dist inet6_tcp" will register with epmd over IPv6 To work on IPv6 capable systems that have IPv6 support disabled, epmd ignores errors opening the socket if the protocol is not supported. Similarly, the epmd client will fall back to IPv4 if the IPv6 socket is not available. Update the minimum supported version of Windows to Windows Vista to support IPv6.

2016-02-02erts: Add microstate accountingLukas Larsson
Microstate accounting is a way to track which state the different threads within ERTS are in. The main usage area is to pin point performance bottlenecks by checking which states the threads are in and then from there figuring out why and where to optimize. Since checking whether microstate accounting is on or off is relatively expensive if done in a short loop only a few of the states are enabled by default and more states can be enabled through configure. I've done some benchmarking and the overhead with it turned off is not noticible and with it on it is a fraction of a percent. If you enable the extra states, depending on the benchmark, the ovehead when turned off is about 1% and when turned on somewhere inbetween 5-15%. OTP-12345
2016-02-02erts, kernel: Add os:perf_counter functionLukas Larsson
The perf_counter is a very very cheap and high resolution timer that can be used to timestamp system events. It does not have monoticity guarantees, but should on most OS's expose a monotonous time. A special instruction has been created for this counter to further speed up fetching it. OTP-12908

2015-12-16erl_prim_loader doc: Remove mention of user supplied loaderBjörn Gustavsson
Custom loaders are no longer supported. Most of the documentation for them were removed in c8a7d2d7.
2015-12-16Clean up start of erl_prim_loaderBjörn Gustavsson
The 'init' module fetches command line parameters and passes them to erl_prim_loader:start/3. The code can be simplified if 'init' calls a new erl_prim_loader:start/0 function that itself fetches the necessary command line parameters. Also remove the documentation for the start() function, since it there is no way that it can be usefully called by a user application. While we are at it, also get rid of '-id' command line parameter, which is fetched and stored but never actually used.
