eff83876b6 Replace several bus_alloc_resource() calls with bus_alloc_resource_any()
Most of these are BARs, and we allocate them in their entirety.  The one outlier
in this is amdsbwd, which calls bus_set_resource() prior.

43cd61606b Replace several bus_alloc_resource() calls using default arguments with bus_alloc_resource_any()
Since these calls only use default arguments, bus_alloc_resource_any() is the
right call.

49b3fc4062 Various fixes to hptmv(4):
- Replace the global driver lock with a per-instance device lock.
- Use the per-instance device lock instead of Giant for the CAM sim lock.
- Add global locks to protect the adapter list and DPC queues.
- Use wakeup() and mtx_sleep() to wait for certain events like the
  controller going idle rather than polling via timeouts passed to
  tsleep().
- Use callout(9) instead of timeout(9).
- Mark the interrupt handler MPSAFE.
- Remove compat shims for FreeBSD versions older than 8.0.

7634a04b30 Apply vendor fixes to the High Point drivers:
- Don't call xpt_free_path() in os_query_remove_device() and
   always return TRUE.
 - Update os_buildsgl() to support build logical SG table which
   will be used by lower RAID module.
 - Return CAM_SEL_TIMEOUTstatus for SCSIcommand failed as target
   missing.

Many thanks to HighPoint for providing this driver update.

eb8a7632ba Re-do r255853. Along with adding back the API/ABI changes from the
original, this hides the contents of cam_compat.h from ktrace/kdump/truss,
avoiding problems there.  There are no user-servicable parts in there, so
no need for those tools to be groping around in there.

185884259b Update the CAM API for FreeBSD 10:
- Remove the timeout_ch field.  It's been deprecated since FreeBSD 7.0;
  MPSAFE drivers should be managing their own timeout storage.  The
  remaining non-MPSAFE drivers have been modified to also manage their own
  storage, and should be considered for updating to MPSAFE (or removal)
  during the FreeBSD 10.x lifecycle.

- Add fields related to soft timeouts and quality of service, to be used
  in upcoming work.

- Add room for more flags in the CCB header and path_inq structures.

- Begin support for extended 64-bit LUNs.

- Bump the CAM version number to 0x18, but add compat shims.  Tested with
  camcontrol and smartctl.

c33c978915 Move hptmv and mpt drivers shutdown a bit later to the SHUTDOWN_PRI_LAST
stage of shutdown_post_sync.  That should allow CAM to do final cache flush
at the SHUTDOWN_PRI_DEFAULT without using polling magic.

dd0b4fb6d5 Reform the busdma API so that new types may be added without modifying
every architecture's busdma_machdep.c.  It is done by unifying the
bus_dmamap_load_buffer() routines so that they may be called from MI
code.  The MD busdma is then given a chance to do any final processing
in the complete() callback.

The cam changes unify the bus_dmamap_load* handling in cam drivers.

The arm and mips implementations are updated to track virtual
addresses for sync().  Previously this was done in a type specific
way.  Now it is done in a generic way by recording the list of
virtuals in the map.

a8bc743735 It seems that what the code really meant is that when a write is completed,
do a BUS_DMASYNC_POSTWRITE over the DMA map.  The way it currently is would
only do POSTREAD for read transactions.

8eadd1b28e When multiple cards are present, register a shutdown handler for each card
instead of just register one for the first adapter.  Without doing this

3745c395ec Rename the kthread_xxx (e.g. kthread_create()) calls
to kproc_xxx as they actually make whole processes.
Thos makes way for us to add REAL kthread_create() and friends
that actually make theads. it turns out that most of these
calls actually end up being moved back to the thread version
when it's added. but we need to make this cosmetic change first.

I'd LOVE to do this rename in 7.0  so that we can eventually MFC the
new kthread_xxx() calls.

b50569b71d 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.

2b83592fdc Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will
use to synchornize and protect all data objects that are used for that
SIM.  Drivers that are not yet MPSAFE register Giant and operate as
usual.  RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.

The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.

4ed23cf283 - Use a regular mutex rather than a spin mutex. This driver doesn't need
a spin mutex since it doesn't have an INTR_FAST interrupt handler.
  Beyond that the driver is still under Giant anyway.
- Remove unneeded locking during attach across operations that can't be
  called with locks held (such as bus_dma_tag_create()).
