behlendo c8e60837b7 * spl-09-fix-kmem-track-oops.patch
This fixes an oops when unloading the modules, in the case where memory
tracking was enabled and there were memory leaks. The comment in the
code explains what was the problem.

* spl-10-fix-assert-verify-ndebug.patch
This fixes ASSERT*() and VERIFY*() macros in non-debug builds. VERIFY*()
macros are supposed to check the condition and panic even in production
builds, and ASSERT*() macros don't need to evaluate the arguments.
Also some 32-bit fixes.

behlendo c22e7a427b Under Solaris KM_SLEEP ensures success (or at least you hang forever).
That said when working with a finite resource like memory failure really
is always a possibility.  It would be far better longer term if the ZFS
code could be weened off this assumption and properly handle the cases
where an allocation fails.  Still I've applied the patch to spl-0.3.4
since this layer is supposed to emulate Solaris as closely as possible.

behlendo a0f6da3d95 Add a SPL_AC_TYPE_ATOMIC64_T test to configure for systems which do
already supprt atomic64_t types.

* spl-07-kmem-cleanup.patch
This moves all the debugging code from sys/kmem.h to spl-kmem.c, because
the huge macros were hard to debug and were bloating functions that
allocated memory. I also fixed some other minor problems, including
32-bit fixes and a reported memory leak which was just due to using the
wrong free function.

them in the IDE IRQ handler.

set_cpus_allowed().  Using this symbol is simpler but in the name
of portability we are adopting a spinlock based solution here
to remove this dependency.

were added to cover the 3 possible APIs from 2.6.9 to
2.6.26.  We attempt to use the newest interfaces and if
not available fallback to the oldest.  This a rework of
some changes proposed by Ricardo for RHEL4.

behlendo 7afde631f6 Start bringing in Ricardo's spl-00-rhel4-compat.patch, a few chunks
at a time as I audit it.  This chunk finishes moving the SPL entirely
off the linux slab on to the SPL implementation.  It differs slightly
from the proposed version in that the spl continues to export to
all the Solaris types and functions.  These do conflict with the
Linux slab so a module usings these interfaces must not include the
SPL slab if they also intend to use the linux slab.  Or they must
explcitly #undef the macros which remap the functioin to their
spl_* equivilants.

A nice side of effect of dropping the entire linux slab is we
don't need to autoconf checks anymore.  They kept messing with
the slab API endlessly!

behlendo a1502d76ae - Remove hash functionality from slab in favor of direct lookups
based of the spl_kmem_obj_t tacked on the end of each object.
  This actually isn't so back because we are now allocing large
  chunks for the slab and partitioning it ourselves.  So there's
  not a ton of wasted space.  We may suffer a performance hit
  however due to alignment issues.

- Remove remaining depenancies on the linux slab implementation.
  We're standing on our own now for better or worse.

- Rework slabs to be either kmem or vmem based.  If neither
  KMC_VMEM of KMC_KMEM are specified we make a decent guess
  about what will work best for their based on the object 
  size.  Additionally we provide a kmem_virt() function caller
  can use to see if they have a virtual or physical address.

- Minor fixups in the test suite.
