Modified files:
sys/cam cam_xpt.c
Log:
Protect access to the EDT with splcam() to protect against corruption
caused by temporary EDT allocations performed by controller drivers in
their interrupt routiens.
Reference count bus entries in the EDT in preparation for support for
dynamic controller arrival and departure.
Have children of the EDT hold references to their parents.
Correct routing of the XPT_IMMED_NOTIFY ccb type for use in
target mode applications.
Fix a few cases where the generation count for EDT data members was
not being updated when a modification occurred.
