I'm using the FSF releases/branches for Debian as well; currently using trunk 
updated to the same base that it used for the HJL releases until the next FSF 
release. This works well except for mips, which shoes regressions in 2.19 and 
trunk (PR10144), and in trunk (-fPIE broken, http://bugs.debian.org/532821).

Ubuntu does use a subset of the patches, which H.J. includes separately in the 
patches directory. AFAICS Fedora does do the same (at least reverting some patches).
