Well, it wouldn't be an *alias*; it would be the prlimit64 entry above.  
But, if the point is to fix things for hppa then you need to arrange for 
hppa to get a GLIBC_2.17 version for prlimit64, not the default GLIBC_2.13 
since in fact the function was missing in 2.13 for hppa - as noted in 
point (v) for hppa in my list at 
<http://sourceware.org/ml/libc-ports/2012-06/msg00048.html>.  (The lack of 
ABI baselines - which of course ought to be checked against binaries of 
old releases when set up - is point (g) on that list, and (x) is another 
point involving checks against old binaries.)

(Adding the entry, but with @@GLIBC_2.17 like the SH fanotify_mark, to the 
hppa syscalls.list along with an appropriate Versions entry, is certainly 
the safer approach than doing something with the potential to affect other 
architectures, even though it may also be good to work out how to clean 
these things up.  Note hppa also needs fanotify_mark at a new version, and 
note that cleanups here only help existing architectures; there are no 
issues for new architectures using linux-generic because linux-generic 
already has the right entries in syscalls.list.)
