2016-05-04	erts: Add macro HAVE_ERTS_MMAP	Sverker Eriksson
	and make erts_mmap unavailable at compile time if not supported.
2016-04-29	erts: Move option info for erts_mmap	Sverker Eriksson
	from {allocator,mseg_alloc} to {allocator,erts_mmap}
2016-04-20	Merge branch 'sverker/hipe-code-alloc'	Sverker Eriksson

2016-04-15	erts: Add 'exec_alloc' for hipe code	Sverker Eriksson
	that uses its own super carrier (erts_exec_mmapper) to guarantee low addressed and executable memory (PROT_EXEC). Currently only used on x86_64 that needs low memory for HiPE/AMD64's small code model. By initializing erts_exec_mapper early we secure its low memory area before erts_literal_mmapper might steal it.
2016-04-15	erts: Make ErtsMemMapper able to map memory with PROT_EXEC	Sverker Eriksson
	to prepare for hipe native code allocation.
2016-04-15	erts: Refactor callbacks for literal mseg alloc	Sverker Eriksson
	Make the callbacks more general to be usable for any allocator that that uses its own ErtsMemMapper.
2016-03-15	update copyright-year	Henrik Nord

2016-02-24	Merge branch 'master' into sverk/master/halt-INT_MIN	Sverker Eriksson

2016-02-24	erts: Change erl_exit into erts_exit	Sverker Eriksson
	This is mostly a pure refactoring. Except for the buggy cases when calling erlang:halt() with a positive integer in the range -(INT_MIN+2) to -INT_MIN that got confused with ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT. Outcome OLD erl_exit(n, ) NEW erts_exit(n, ) ------- ------------------- ------------------------------------------- exit(Status) n = -Status <= 0 n = Status >= 0 crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0 The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and ERTS_DUMP_EXIT are the same as before (even though their values have changed).

2013-11-05	Replace the +MMscmgc switch with +MMscrfsd	Rickard Green
	Replaced the +MMscmgc switch with the +MMscrfsd switch. The old switch didn't reflect what it controlled.
