[parisc-linux] PA8800 Status (Happy New Year)

[John David Anglin]

I spent the last couple of days updating the kernel and userspace
software on the pa8800 that I have (ior).  The good news is that
the machine is now much more stable than it was.  ssh seems to
work.  I've even been able to do a full GCC build on it.  Thanks
to all for the fixes!

The bad news.  The system died almost immediately starting the
gcc testsuite:

>From the console log:

expect (pid 20348): Protection id trap (code 27)
