55152ebbb4 * modules/spl/spl-kmem.c : Make sure to disable interrupts
when necessary to avoid deadlocks.  We were seeing the deadlock
        when calling kmem_cache_generic_constructor() and then an interrupt
        forced us to end up calling kmem_cache_generic_destructor()
        which caused our deadlock.

d61e12af5a - Add some spinlocks to cover all the private data in the mutex. I don't
think this should fix anything but it's a good idea regardless.

- Drop the lock before calling the construct/destructor for the slab
otherwise we can't sleep in a constructor/destructor and for long running
functions we may NMI.

- Do something braindead, but safe for the console debug logs for now.

0a6fd143fd - Remapped ldi_handle_t to struct block_device * which is much more useful
- Added liunx block device headers to sunldi.h
- Made __taskq_dispatch safe for interrupt context where it turns out we
  need to be useing it.
- Fixed NULL const/dest bug for kmem slab caches
- Places debug __dprintf debugging messages under a spin_lock_irqsave
  so it's safe to use then in interrupt handlers.  For debugging only!

8d0f1ee907 Add some crude debugging support. It leaves alot to be
desired, but it should allow more easy kernel debugging for now.

e4f1d29f89 OK, some pretty substantial rework here. I've merged the spl-file
stuff which only inclused the getf()/releasef() in to the vnode area
where it will only really be used.  These calls allow a user to
grab an open file struct given only the known open fd for a particular
user context.  ZFS makes use of these, but they're a bit tricky to
test from within the kernel since you already need the file open
and know the fd.  So we basically spook the system calls to setup
the environment we need for the splat test case and verify given
just the know fd we can get the file, create the needed vnode, and
then use the vnode interface as usual to read and write from it.

While I was hacking away I also noticed a NULL termination issue
in the second kobj test case so I fixed that too.  In fact, I fixed
a few other things as well but all for the best!

c19c06f3b0 Fix kmem memory accounting
Adjust kmem slab interface to make a copy of the slab name before
passing it on to the linux slab (we free it latter too)

f4b377415b Reorganize /include/ to add a /sys/, this way we don't need to
muck with #includes in existing Solaris style source to get it
to find the right stuff.

596e65b4e8 OK, I think this is the last of major cleanup and restructuring.
We've dropped all the linux- prefixes on the file in favor of spl-
which makes more sense.  And we've cleaned up some of the includes
so everybody should be including their own dependencies properly.
All a module which wants to use the spl support needs to do in
include spl.h and ensure it has access to Module.symvers.
