8bef431273 remove unused share map code from UVM: 
- update calls to uvm_unmap_remove/uvm_unmap (mainonly boolean arg
        has been removed)

b9d844a520 Allocate a private PCB, kernel stack and interrupt stack for each processor. 
As a result, the stack setup code in locore.s changes slightly in
the MULTIPROCESSOR case. Also, make the stack redzone barrier (for
debugging only) a per-CPU entity.

908cdfe4e3 Add scsibus entry points to the cdevsw[]. 1998-10-10 02:00:49 +00:00

29d472f53d Garbage-collect the open_target_lu and close_target_lu entry points from 
struct scsipi_adapter; they were not used.

Add a scsipi_ioctl entry point to struct scsipi_adapter.  This will be
used to issue ioctl commands to the host adapters.

Inspired by PR #6090, from Matt Jacob.
