base offset before using it. This makes it work the same as every other
implementation, and makes wdc at pioc on acorn32 work again. Fix the only
caller I found which depended on the old behaviour.
Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.
Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded. Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.
All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.
PS - I'm sorry, but there's a distinct lack of documentation at the
moment. I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.
In the interrupt dispatch loop, make sure to handle any pending interrupts
which came in while we were dealing with the first interrupt(s), and which
are enabled at the current spl.
This fixes a problem where the intr_enabled/hw mask is not updated to
allow pending interrupts through until the next splx(). In some case,
interrupts could be delayed until the next clock tick.

called from userspace, and that messes things up.
Thanks to Mark Kettenis to pointing out that not using an alt stack
solved the "loop on gdb sig continuation" issue.
