* Factor out the common code between the isa bus drivers for i386 and alpha. * Re-work the resource allocation code to use helper functions in subr_bus.c. * Add simple isa interface for manipulating the resource ranges which can be allocated and remove the code from isa_write_ivar() which was previously used for this purpose.

Alter the behavior of sys/kern/subr_bus.c:device_print_child() - device_print_child() either lets the BUS_PRINT_CHILD method produce the entire device announcement message or it prints "foo0: not found\n" Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on the previous behavior of device_print_child() (printing the "foo0: <FooDevice 1.1>" bit of the announce message.)

These functions should be used whenever possible (unless you can just use bus_generic_print_child()) The BUS_PRINT_CHILD method now returns int instead of void. Modify everything else that defines or uses a BUS_PRINT_CHILD method to comply with the above changes. - Devices are 'on' a bus, not 'at' it. - If a custom BUS_PRINT_CHILD method does the same thing as bus_generic_print_child(), use bus_generic_print_child() - Use device_get_nameunit() instead of both device_get_name() and device_get_unit() - All BUS_PRINT_CHILD methods return the number of characters output.
