MFC r267368:

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.

MFC r250460 (by eadler):
Fix a bunch of typos.

Big MFC of the physbio changes necessary for unmapped I/O. These changes
have been in production at Netflix for several months with significant
success.

MFC r246713:

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.

MFC r249538:
Some compilers issue a warning when wider integer is casted to narrow
pointer. Supposedly shut down the warning by casting through
uintptr_t.

MFC r251479:
Simplify the checking of flags for cam_periph_mapmem(). This gets rid of
a lot of code redundancy and grossness at very minor expense.

MFC r251837:
MFC r251842:
Add infrastructure for doing compatibility shims, as has been sorely
needed for the last 10 years. Far too much of the internal API is
exposed, and every small adjustment causes applications to stop working.
To kick this off, bump the API version to 0x17 as should have been done
with r246713, but add shims to compensate. Thanks to the shims, there
should be no visible change in application behavior.

MFC r249849:
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.

MFC r240210:

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.

Use DEVICE_SHUTDOWN(9) mechanism for shutdown handler.

Suggested by: jhb

When multiple cards are present, register a shutdown handler for each card
instead of just register one for the first adapter. Without doing this
there would be some data loss upon shutdown because data could be ignored
when flushing to disk.

Update driver to vendor's version 1.16 plus some local changes:

- override_kernel_driver() has been removed since this is an
in-tree version of driver.
- __DATE__ and __TIME__ removed from version string to make
binary update builders happy.
- Utilize pause(9) for __FreeBSDversion >= 700033 (redo 167086).
- Utilize kproc_suspend_check() for __FreeBSDversion >= 800002.
(redo 172836).
- Don't read past end of pVDevice (redo 143787).
- Make sure that controller and channel are initialized (redo 169823).
- Don't include cam/cam_xpt_periph.h (redo 158177).

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.

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.

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.

Use pause() rather than tsleep() on stack variables and function pointers.

o break newbus api: add a new argument of type driver_filter_t to
bus_setup_intr()

o add an int return code to all fast handlers

o retire INTR_FAST/IH_FAST

- 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()).

Not objected to by: scottl

Since DELAY() was moved, most <machine/clock.h> #includes have been
unnecessary.

Don't augment the DRIVER_VERSION "v1.12" with __DATE__ and __TIME__.
This is the only file of > 1700 files in a buildkernel here doing that.
It makes reproducible builds (same source => same binary) impossible.
