- 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.

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.

- 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.

here is the support for amd64, as well as possible support for PAE. Many
thanks to Highpoint for continuing to support FreeBSD.
