wartens2 8100fe56f1 Make sure that when calling __vmem_alloc that we
do not have __GFP_ZERO set.  Once the memory is allocated
then zero out the memory if __GFP_ZERO is passed to
__vmem_alloc.

behlendo 937879f11d Update SPL to use new debug infrastructure. This means:
- Replacing all BUG_ON()'s with proper ASSERT()'s
- Using ENTRY,EXIT,GOTO, and RETURN macro to instument call paths

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

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!

behlendo 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.
