I had a request to backport this patch to the 4.6 branch and since it is an obvious fix and hasn't caused any problems on the main line I have gone ahead and checked it in. I tested the patch on the 4.6 branch with IA64 HP-UX and had no regressions.
FYI: Friday will be my last day at HP but I will be starting at MIPS next week and working on GCC. I will change my email address in the MAINTAINERS file after I start at MIPS.
