This the important effect of forcing a link error if the user is

The correct isa vector line for the bt driver is "vector bt_isa_intr".
Justin mentioned this in the commit message and updated LINT and

most devsw referenced functions are now static, as they are

many of the devices have 'incorrect' names under DEVFS

If you "OWN" a device which would normally have an entry in /dev

The script is now copied to memory mapped using vm_page_alloc_contig(),

Two of the probe messages are suppressed, unless "bootverbose" is set.
contiguous memory in virtual space, but doesn't guarantee any particular
physical layout of pages, the script may be not contguous in physical

This has been fixed by checking the region returned by malloc() for

and later mapping to virtual memory instead.
A few assertions and error messages are improved.
This change forces the controller drivers to allocate a scsibus_data struct
via a call to scsi_alloc_bus(), fill in the adapter_link field, and optionally
modify any other fields of the struct. Scsi_alloc_bus() initializes all fields
to the default, so the changes in most drivers are very minimal. For drivers
that support Wide controllers, the maxtarg field will have to be updated to
allow probing of all targets (for an example, look at the aic7xxx driver).
Scsi_attachdevs() now takes a scsibus_data* as its argument instead of an
sc_link*. This allows us to expand the role of the scsibus_data struct for
other bus level configuration setings (max number of transactions, current
transaction opennings, etc for better tagged queuing support).
