Seems reasonable - is your suggestion that the backport request be filed 
as soon as the patch goes in on master, even if it would be a good idea to 
allow the patch some time in master in case of any problems on other 
architectures, before backporting?

My impression is that the various recent libm-test-ulps changes should be 
backported as the relevant library / testsuite changes were already in 
2.15.  And I think Aurelien's change to floating-point comparisons is also 
relevant for 2.15.
