b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

282070b3e8 Minor updates:
- Rework of twe_report_request to use the command status value rather
   than the flags register. (Joel Jacobson @ 3ware)
 - Update to match some changes in -current vs. stable.

6b8b8c7fdc Last commit was broken.. It always prints '[CTRL-C to abort]'.
Move duplicate code for printing the status of the dump and checking
for abort into a separate function.

f2a404d5a6 Change the dump routines to only abort if control-c is pressed.
If any other key is pressed, print a message stating that control-c
is how to abort.

ed34d0ade2 Turn on interrupt-entropy harvesting for all/any mass storage devices
I could find. I have no doubt missed a couple.

Interrupt entropy harvesting is still conditional on the
kern.random.sys.harvest_interrupt sysctl.

b09d2ca319 - add support for crashdumps (courtesy of ps and Y!)
- standardise error reporting for commands
 - simplify the driver-to-controller bio transfer
 - add bio in/out accounting
 - correctly preserve the command ID in twe_ioctl (thanks to joel@3ware)

76ba114c80 If we can't get a command to back the bio we just took off the queue,
put the bio back, otherwise we'll drop it when we bail.  This was
causing bio lossage under load, leading to eventual system lockup.

e6c12d85d0 Major update to the 'twe' driver.
- Layout reorganisation to enhance portability.  The driver now has
   a relatively MI 'core' and a FreeBSD-specific layer over the top.
   Since the NetBSD people have already done their own port, this is
   largely just to help me with the BSD/OS port.

 - Request ID allocation changed to improve performance (I'd been
   considering switching to this approach after having failed to come
   up with a better way to dynamically allocate request IDs, and seeing
   Andy Doran use it in the NetBSD port of the driver convinced me
   that I was wasting my time doing it any other way).  Now we just
   allocate all the requests up front.

 - Maximum request count bumped back to 255 after characterisation
   of a firmware issue (off-by-one causing it to crash with 256
   outstanding commands).

 - Control interface implemented.  This allows 3ware's '3dm' utility to
   talk to the controller.  3dm will be available from 3ware shortly.

 - Controller soft-reset feature added; if the controller signals a
   firmware or protocol error, the controller will be reset and all
   outstanding commands will be retried.

b1e68a44b5 Reduce the number of outstanding commands we will send to the controller
to 50.  This has been reported to avoid the problems that many users have
been experiencing with crashing the card firmware during rebuilds.
