The current tree at
https://github.com/hdeller/qemu-hppa/commits/target-hppa
does survive all your tests and in addition fixes an artist bug which
made the dtwm window manager rendering wrong on HP-UX.
Please completely revert your tree before pulling again.
I'll send out a complete patch series shortly.

Thanks!
Helge
