2016-05-04	erts: Add macro HAVE_ERTS_MMAP	Sverker Eriksson
	and make erts_mmap unavailable at compile time if not supported.
2016-05-04	erts: Refactor erl_mmap.h	Sverker Eriksson
	by (only) moving around stuff in the file. in order to make it easier to ifdef away all erts_mmap_* if not supported.
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: Tweak defaults for literal allocator	Sverker Eriksson
	Reduce main carrier size and number of free descriptors.
2016-03-15	update copyright-year	Henrik Nord

2016-02-23	erts: Make literal_alloc documented and configurable	Sverker Eriksson
	Except it cannot be disabled and cannot be multi-threaded. The bit-vector 'erts_literal_vspace_map' on 32-bit is currently only protected by the literal allocator mutex. We could allow multiple instances on 64-bit (I think), but what would be the point?
2015-11-12	erts: Add support for fast erts_is_literal()	Sverker Eriksson

2015-11-12	erts: Refactor erl_mmap to allow several mapper instances	Sverker Eriksson

2015-09-11	erts: Remove unused erts_have_erts_mmap	Sverker Eriksson

2015-06-18	Change license text to APLv2	Bruce Yinhe

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.
2013-09-30	erts: Add erts_mmap stats	Sverker Eriksson
	As part of erlang:system_info({allocator,mseg_alloc}) and erl_crash.dump
2013-09-30	erts: Add HARD_DBG_MSEG	Sverker Eriksson

2013-09-30	erts: Allow page aligned erts_munmap()	Rickard Green

2013-09-30	erts: Add mmap argument to erts_debug:get_internal_state	Sverker Eriksson

2013-09-30	erts: erts_mmap supercarrier management and erts_mseg usage	Rickard Green
	* Coalescing and trimming of free segments in supercarrier * Management of super aligned and super unaligned areas in supercarrier * Management of reservation of physical memory * erts_mseg usage of erts_mmap
2013-09-30	erts: Prepare erl_mmap with tree structures for free seg storage	Sverker Eriksson
