+Subject: [PATCH] bpo-36044: Reduce number of unit tests run for PGO build
+ (GH-14702)
+
+Reduce the number of unit tests run for the PGO generation task.  This
+speeds up the task by a factor of about 15x.  Running the full unit test
+suite is slow.  This change may result in a slightly less optimized build
+since not as many code branches will be executed.  If you are willing to
+wait for the much slower build, the old behavior can be restored using
+'./configure [..] PROFILE_TASK="-m test --pgo-extended"'.  We make no
+guarantees as to which PGO task set produces a faster build.  Users who
+care should run their own relevant benchmarks as results can depend on
+the environment, workload, and compiler tool chain.
+(cherry picked from commit 4e16a4a3112161a5c6981c0588142d4a4673a934)

+Subject: [PATCH] [3.8] bpo-41302: Support system libmpdec 2.5 for Python 3.8
+ (GH-21488)
+
+Define UNUSED only when mpdecimal.h doesn't define it. This would support
+building with system libmpdec 2.5 while retaining compatibility with system
+libmpdec 2.4 or the vendored copy.
+
+Tested to build fine with either system libmpdec or the vendored one.
