+Subject: [PATCH] erts/ethread: instruct libatomic_ops we do require CAS
+
+We do require compare-and-swap (CAS), so we must instruct libatomic_ops
+to provide it, even if the architecture does not have instructions for
+it.
+
+For example, on ARM, LDREX is required for fast CAS. But LDREX is only
+available on ARMv6, so by default libatomic_ops will not have CAS for
+anything below, like ARMv5. But ARMv5 is always UP, so using an
+emulated CAS (that is signal-asyn-safe) is still possible (albeit much
+slower).
+
+Tell libatomic_ops to provide CAS, even if the hardware is not capable
+of it, by using emulated CAS, as per libatomic_ops dosc:
+    https://github.com/ivmai/libatomic_ops/blob/master/doc/README.txt#L28
+
+    If this is included after defining AO_REQUIRE_CAS, then the package
+    will make an attempt to emulate compare-and-swap in a way that (at
+    least on Linux) should still be async-signal-safe.
+
+Thanks go to Thomas for all this insight! :-)
+Thanks go to Frank for reporting the issue! :-)

+Subject: [PATCH] erts/emulator: reorder inclued headers paths
+
+If the Perl Compatible Regular Expressions is installed on the
+host and the path to the headers is added to the CFLAGS, the
+pcre.h from the host is used instead of the one provided by
+erlang.
+
+Erlang use an old version of this file which is incompatible
+with the upstream one.
+
+Move INCLUDES before CFLAGS to use pcre.h from erlang.

+	  Erlang is a programming language used to build massively scalable
+	  soft real-time systems with requirements on high availability.
+	  Some of its uses are in telecoms, banking, e-commerce, computer

+	  Erlang provides both a UP and an SMP emulator. The UP emulator
+	  is always built, and this option enables compilation of the SMP
+	  emulator. The choice of which emulator to use is made at runtime.
+	  If you do not need SMP support, turning this option off reduces
