This patch causes all my 32-bit parisc qemu tests with C3700 machine
to fail. Network interface tests fail, and all boot attempts from
any kind of hard drive (scsi, usb) fail with this patch in the tree.
Thanks for the report. I have a fix ready; I'll clean it up and send it out
by EOD.
The fix is available here

Thanks
