--- Comment #2 from Gustavo Moreira <mysecondaccountabc at gmail dot com> ---
It seems a4-a7 registers exist in n32 but not in o32.
Debian uses o32, so it seems SystemTap struggles to detect the ABI or it just
uses n32 by default.
The kernel is a prebuilt one. I got it from
(http://ftp.debian.org/debian/dists/stretch/main/installer-mipsel/current/images/malta/netboot/vmlinux-4.9.0-4-4kc-malta)
I've extracted the .config file from kernel and I've attached it to this
ticket.
