Good point, thanks a lot! I got confused because the SIGBUS handler
checked for siginfo->si_code == BUS_ADRALN to see if the SIGBUS was
caused by unaligned accesses, but it turns out that Linux 3.2 on MIPS
reports SI_KERNEL instead in that case. I managed to track down the
issue with some help from upstream; the bug should be fixed in the
next upload.

Thanks!
