Module Name:    src
Committed By:   thorpej

        src/sys/kern: subr_device.c
        src/sys/sys: device.h

Log Message:
Introduce the notion of a "system default" device call provider.  This
is useful on a platform like sparc, where a single booted kernel can
support OpenFirmware, pre-OFW OpenBOOT, or the "old ROM" universe that
does not have a platform device tree, but has platform-specific logic
for handling some kinds of device properties.  The SYSDFLT get a crack
if the normal by-handle device call lookup fails.
