I found the issue. pmap_protect wasn't updated for sparse pde array.
Whenever ext2fs would ping memory beyond a pde limit, things would go
mayhem.

And since nobody had yet fixed the debugging tools for x86_64
completely, the symptom was terribly far from the real issue.

In the end I eventually forged simple_lock_irq helpers to possibly fix
some bugs, at least it'll make maintenance of spl for simple_locks
simpler. I'll push that soon.

Generally, please do not underestimate the vast benefit of fixing our
debugging tools.

Concerning the x86_64 port, we very probably want to port gdb ASAP, to
be able to e.g. fix the glibc testsuite. For instance, I see that perl's
configure hangs at some point, apparently due to a buffering issue in
the "<< EOF" processing of the shell.
