1c95a6b2b4 Lock iir(4) and mark it MPSAFE.
- Add a per-device mutex to the softc and use it for bus_dma tags,
  CAM SIMs, callouts, and interrupt handler.
- Switch from timeout(9) to callout(9).
- Add a separate global mutex to protect the global event buffer ring.
- Return completed index from iir_intr_locked() and remove the global
  gdt_wait_* variables.
- Remove global list of gdt softcs and replace its use with
  devclass_get_device().
- Use si_drv1 to store softc pointer in the SDEV_PER_HBA case instead
  of minor numbers.
- Do math on osreldate instead of dubious char math on osrelease[]
  that didn't work on 10.0+.
- Use bus_*() instead of bus_space_*().
- Use device_printf() instead of printf() with a unit number.

ff584e70fa Prepare for future integration between CAM and newbus. xpt_bus_register
now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now.  This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.

ff94cb013a Big update to the iir driver:
- Don't use a common buffer in the softc to store per-command data.  Reserve
  a buffer in the command itself.
- Don't allocate DMA memory for the kernel command structures when all you
  really need is DMA memory for the scratch buffer embedded in them.  Instead
  allocate a slab for the scratch buffers and divide it up as needed.
- Call bus_dmamap_unload() at the completion of commands.
- Preserve and clear the CAM CCB status flags at completion.
- Reorder some low-level command operations to try to close races.
- Limit the simq to 32 commands for now.  There are some serious problems
  with the driver under load that are not well understood, so keeping the
  simq lower helps avoid this.  It has been tested at a higher value, but
  this is a safe value that doesn't show much performance degredation.

These changes allow the driver to work reliably with >4GB of memory on i386
and amd64, and also work around deadlocks seen under very high load in
certain situations.  The work-around is far from ideal, but without and
documentation it is hard to know what the right fix is.

4d495abb9d Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.
