After talking to Ley Foon Tan (Altera's kernel maintainer, in Cc)
we've decided to just drop
this patch entirely. An architecture port based in the generic syscall
ABI is in progress:

http://rocketboards.org/gitweb/?p=linux-socfpga-next.git;a=shortlog;h=refs/heads/socfpga-3.12-nios2-ABI

I'll work on a new patchset, based in this branch, so we can have
strace support for the
(soon?) to-be-mainlined Nios-II arch.

Thanks Ley Foon for the heads-up!
