99639e4a13 Add zone_get_hostid() function
Minimal support added for the zone_get_hostid() function.  Only
global zones are supported therefore this function must be called
with a NULL argumment.  Additionally, I've added the HW_HOSTID_LEN
define and updated all instances where a hard coded magic value
of 11 was used; "A good riddance of bad rubbish!"

36b313dacf Linux VM integration / device special files
Support added to provide reasonable values for the global Solaris
VM variables: minfree, desfree, lotsfree, needfree.  These values
are set to the sum of their per-zone linux counterparts which
should be close enough for Solaris consumers.

When a non-GPL app links against the SPL we cannot use the udev
interfaces, which means non of the device special files are created.
Because of this I had added a poor mans udev which cause the SPL
to invoke an upcall and create the basic devices when a minor
is registered.  When a minor is unregistered we use the vnode
interface to unlink the special file.

ea3e6ca9e5 kmem_cache hardening and performance improvements
- Added slab work queue task which gradually ages and free's slabs
  from the cache which have not been used recently.
- Optimized slab packing algorithm to ensure each slab contains the
  maximum number of objects without create to large a slab.
- Fix deadlock, we can never call kv_free() under the skc_lock.  We
  now unlink the objects and slabs from the cache itself and attach
  them to a private work list.  The contents of the list are then
  subsequently freed outside the spin lock.
- Move magazine create/destroy operation on to local cpu.
- Further performace optimizations by minimize the usage of the large
  per-cache skc_lock.  This includes the addition of KMC_BIT_REAPING
  bit mask which is used to prevent concurrent reaping, and to defer
  new slab creation when reaping is occuring.
- Add KMC_BIT_DESTROYING bit mask which is set when the cache is being
  destroyed, this is used to catch any task accessing the cache while
  it is being destroyed.
- Add comments to all the functions and additional comments to try
  and make everything as clear as possible.
- Major cleanup and additions to the SPLAT kmem tests to more
  rigerously stress the cache implementation and look for any problems.
  This includes correctness and performance tests.
- Updated portable work queue interfaces

57d862349b Breaking the world for a little bit. If anyone is going to continue
working on this branch for the next few days I suggested you work
off of the 0.3.1 tag.  The following changes are fairly extensive
and are designed to make the SPL compatible with all kernels in
the range of 2.6.18-2.6.25.  There were 13 relevant API changes
between these releases and I have added the needed autoconf tests
to check for them.  However, this has not all been tested extensively.
I'll sort of the breakage on Fedora Core 9 and RHEL5 this week.

- Using ENTRY,EXIT,GOTO, and RETURN macro to instument call paths

57d1b18858 First commit of lustre style internal debug support. These
changes bring over everything lustre had for debugging with
two exceptions.  I dropped by the debug daemon and upcalls
just because it made things a little easier.  They can be
readded easily enough if we feel they are needed.

Everything compiles and seems to work on first inspection
but I suspect there are a handful of issues still lingering
which I'll be sorting out right away.  I just wanted to get
all these changes commited and safe.  I'm getting a little
paranoid about losing them.

d429b03d85 - Thinko fix to the SPL module interface
- Enhanse the VERIFY() support to output the values which
  failed to compare as expected before crashing.  This make
  debugging much much much easier.

9490c14835 Apply fix from bug239 for rwlock deadlock.
Update check.sh script to take V=1 env var so you can run it verbosely as
follows if your chasing something: sudo make check V=1

Add new kobj api and needed regression tests to allow reading of files from
within the kernel.  Normally thats not something I support but the spa layer
needs the support for its config file.

Add some more missing stub headers
