To do it right for split root/usr installations requires a few patches
though. The rtld and the libs required for /[s]bin need to move to /

Probably they should provide an identify method to look for and create the

In the long run, I think we need either an extra parameter to
rman_reserve_resource() or a new api rman_reserve_resource_aligned().
This also implies changing the method BUS_ALLOC_RESOURCE() or adding

. The kernel returns ENEEDAUTH from
the nfssvc() call and nfsd does the authentication, passing the results
back via nfssvc(). I don't think this code is actually used by anyone so
there is a strong possibility that it doesn't work at all.

I think I will tackle that soon.

mplemented by pccard as well.
For PCI, we need to change the probe slightly to pass the RID for the port
resource (always zero for isa but normally nonzero for pci). In this case,
the GET/SET_RESOURCE methods probably won't be needed since they are just
used for the multiport kluge

The value 255 for intline represents "not configured" or "no interrupt".

.2 has not been released (gdb-4.18 was
based on a snapshot of 2.9.2).
The linux folks often just bundle patches with the gdb sources which is
not much different from us importing FSF sources into our CVS tree. We can
generate diffs from the virgin FSF sources very easily.
