This patch adds an M_NOFREE flag which allows one to mark an mbuf as

Add entries for Epson multifunction scanner/printer/card readers,

to the table of recognised devices (because there is no standard
'scanner' class, so no other way to recognise them), and with
a small change to the uscanner attach routine that prevents
reconfiguring the whole USB device while we are dealing only with
one of its USB interfaces.
The latter part has been suggested by Steinar Hamre in
http://www.freebsd.org/cgi/query-pr.cgi?pr=107665 , i have
only added a bit of explaination to the code.
I have personally tried this on the Epson DX-5050 and DX-6000
devices (on the US market they have different names, CX-something).
I have good reasons to think that, possibly with the mere addition
of more USB ids to the table in uscanner.c, this should work with
all Epson multifunction devices in that family (from DX-3800 to
DX-7000 - these units are in the 50-120$ price range).

Make selector parsing accept the dot "." as an alternative selector
with identical meaning as the colon ":". This is to support a syntax
that is more similar to a PCI device specification in the device hints
file. The selector is not fully compatible with the specification in
the hints file, since entries in that file use a different prefix,
which needs to be added to the getsel() routine, if full support of
that syntax is found to be desirable.
Restore compatibility with version before introduction of PCI domains.
PCI selectors with 2 or 3 elements behave exactly as before (i.e. the
domain is 0 and in the 2 element case, the function is also 0).
The form with 4 selector elements works as in the previous revision
and provides the PCI domain number as the left-most selector element.
This change allows old scripts (which used the 2 or 3 selector element
formats) to be kept. Without this patch, the 3 element form was parsed
as starting with a domain number (and the function was assumed to be 0),
with this patch, the domain is assumed to be 0 (and the last value is
used as the function number).
The man page is updated to describe the new selector semantics.

Make the PCI code aware of PCI domains (aka PCI segments) so we can
support machines having multiple independently numbered PCI domains
and don't support reenumeration without ambiguity amongst the

This includes introducing a function pci_find_dbsf(9) which works
like pci_find_bsf(9) but additionally takes a domain number argument
and limiting pci_find_bsf(9) to only search devices in domain 0 (the
only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are
changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order
to no longer report false positives when searching for siblings and
dupe devices in the same domain respectively.
Along with this change the sole host-PCI bridge driver converted to
actually make use of PCI domain support is uninorth(4), the others
continue to use domain 0 only for now and need to be converted as
appropriate later on.
Note that this means that the format of the location strings as used
by pciconf(8) has been changed and that consumers of <sys/pciio.h>
potentially need to be recompiled.

When orphaning a provider, cancel events related to it.
Without this change the following situation was possible:
1. Provider is orphaned from within class' access() method on last write
close - orphan provider event is send.
2. GEOM detects last write close on a provider and sends new provider event.
3. g_orphan_register() is called, and calls all orphan methods of attached
consumers.
4. New provider event is executed on orphaned provider, all classes can
taste already orphaned provider, and some may attach consumers to it.
Those consumers will never go away, because the g_orphan_register()
