- Always check mdnew() return value, as even in !autounit case
kthread_create() can fail.
Those two changes fix serval panics provoked by simple stress test.

Prevent division by zero errors in sc_mouse_move()
by explicitly setting sc->font_width, in the same
places where sc->font_size is set, instead of
relying on the default initialized value of 0 for sc->font_width.

Remove an erroneous m_freem() call. If m_defrag() returns a non-NULL
pointer, it has already freed the original mbuf chain, so we shouldn't
do it again.

- Wrap the handler and associated code for collecting completed RX
descriptors that are still marked owned in #ifdef GEM_RINT_TIMEOUT
instead of #if 0 for convenience.
- Remove stale code and comment about relying on the preset XIF config.
- In case of a watchdog timeout call the init function instead of just
the start function so the chip is properly reset.
Merge from hme(4):
- Convert to use bus_dmamap_load_mbuf_sg() for loading RX buffers.
- Protect from a duplicate mbuf free panic in case the DMA engine hangs.

- Change the code that determines whether to use a serial console and
which serial device to use in that case respectively to not rely on

it save on some variables and for sys/boot/sparc64/loader/metadata.c
move the code in question to a new function md_bootserial() so it can
be kept in sync with uart_cpu_getdev_console() more easily.

HEAD to RELENG_6: changes to introduce a credentialed version of the
clone event handler, and then changes to merge the regular and
credentialed versions into a single interface (along with updates to
existing consumers). With this merge, 6.x and 7.x are in sync.
First batch merges devfs_devs.c:1.37, devfs_vnops.c:1.115,
kern_conf.c:1.187, tty_pty.c:1.138, mac_vfs.c:1.109, mac_biba.c:1.36,
mac_lomac.c:1.36, mac_mls.c:1.73, mac_stub.c:1.53, mac_test.c:1.61,
conf.h:1.223, mac.h:1.68, mac_policy.h:1.67 from HEAD to RELENG_6:
When devfs cloning takes place, provide access to the credential of the
process that caused the clone event to take place for the device driver
creating the device. This allows cloned device drivers to adapt the
device node based on security aspects of the process, such as the uid,
gid, and MAC label.
- Add a cred reference to struct cdev, so that when a device node is
instantiated as a vnode, the cloning credential can be exposed to
MAC.
- Add make_dev_cred(), a version of make_dev() that additionally
accepts the credential to stick in the struct cdev. Implement it and
make_dev() in terms of a back-end make_dev_credv().
- Add a new event handler, dev_clone_cred, which can be registered to
receive the credential instead of dev_clone, if desired.
- Modify the MAC entry point mac_create_devfs_device() to accept an
optional credential pointer (may be NULL), so that MAC policies can
inspect and act on the label or other elements of the credential
when initializing the skeleton device protections.
- Modify tty_pty.c to register clone_dev_cred and invoke make_dev_cred(),
so that the pty clone credential is exposed to the MAC Framework.
While currently primarily focussed on MAC policies, this change is also
a prerequisite for changes to allow ptys to be instantiated with the UID
of the process looking up the pty. This requires further changes to the
pty driver -- in particular, to immediately recycle pty nodes on last
close so that the credential-related state can be recreated on next
lookup.

Second batch merges scsi_target.c:1.68, coda_fbsd.c:1.43,

smb_dev.c:1.28, conf.h:1.224 from HEAD to RELENG_6:
Merge the dev_clone and dev_clone_cred event handlers into a single
event handler, dev_clone, which accepts a credential argument.
Implementors of the event can ignore it if they're not interested,
and most do. This avoids having multiple event handler types and
fall-back/precedence logic in devfs.
This changes the kernel API for /dev cloning, and may affect third
party packages containg cloning kernel modules.
Requested by: phk
These changes modifies the kernel device driver API for device cloning,
and might require minor modifications to third party device drivers that
make use of devfs cloning. It will not be merged to RELENG_5.
