behlendo 996faa6869 Correctly implement atomic_cas_ptr() function. Ideally all of these
atomic operations will be rewritten anyway with the correct arch
specific assembly.  But not today.

behlendo 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!

behlendo 0998fdd6db Apparently it's OK for done to be NULL, which was not clear in the
Solaris man page.  Anyway, since apparently this usage is accectable
I've updated the function to handle it.

behlendo 6a585c61de Double large kmalloc warning size to 4 pages. It was 2 pages, and ideally
it should be dropped to one page but in the short term we should be able
to easily live with 4 page allocations.

Fix the nvlist bug, it turns out the user space side of things were
packing the nvlists correctly as little endian, and the kernel space
side of things due to a missing #define were unpacking them as big endian.

behlendo 4e62fd4104 OK, a first reasonable attempt at a solaris module/chdev shim layer.
This should handle the absolute minimum I need for ZFS.  It will 
register the chdev with the right callbacks.  Then the generic 
registered linux callback will find the right registered solaris
callback for the function and munge the args just right before
passing it on.  Should work, but untested (just compiled), so I
expect bugs.

behlendo 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!

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.
