Parts of the project:
a) Some patches upstream and done
b) Reset targets on remaining features still to be done (jit support, symbol names)

Never mind.
'git describe' seems to think they are in 3.19-rcX but they are
not in 3.19.
$ git describe fd979c0
v3.19-rc2-62-gfd979c0
$ git describe aaea361
v3.19-rc4-172-gaaea361
They were merged on Feb 2, so they should be in 4.0
