Rasperry Pi firmware has a set of hardcoded pathes it uses to fill
FDT with system-specific information like display resolution, memory
size, UART and SDHCI clocks, ethernet MAC address. Handle two of them:
- Add placeholder for ethernet MAC address
- Move display node out of "axi" node
... instead of the ever increasing ones.
Also, do free old resources when allocating new ones when cx states
change.

vnode and following back the chain of n_parent pointers up to the root,
without acquiring the locks of the n_parent vnodes analyzed during the
computation. This is immediately wrong because if the vnode lock is not
held there's no guarantee on the validity of the vnode pointer or the data.
In order to fix, store the whole path in the smbnode structure so that
smbfs_fullpath() can use this information.

- The feature is dangerous because the kernel code didn't check
validity of the memory address provided from user space.
- It seems that mdconfig(8) never really supported attaching preloaded
memory disks.
- Preloaded memory disks are automatically attached during md(4)
initialization. Thus there shouldn't be much use for the feature.

This is the missing piece for FreeBSD/Wii, but there's still a lot of
work ahead. We have to reset the MMU in locore before continuing
the boot process because we don't know how the boot loaders might
have setup the BATs. We also disable the PCI BAT because there's no PCI
bus on the Wii.

the unix domain sockets to the next tick, coalescing the serial calls
until the collection fires. The thought is that more work for the
collector could arise in the near time, allowing to clean more and not
spend too much CPU on repeated collection when there is no garbage.
Currently the collection task is fired immediately upon unix domain
socket close if there are any rights in flight, which caused excessive
CPU usage and too long blocking of the threads waiting for
unp_list_lock and unp_link_rwlock in write mode.
Robert noted that it would be nice if we could find some heuristic by
which we decide whether to run GC a bit more quickly. E.g., if the
number of UNIX domain sockets is close to its resource limit, but not
quite.

already armed and the ticks is negative. Otherwise rearm it to fire
in abs(ticks) ticks in the future.
The intended use is to call taskqueue_enqueue_timeout() for the given
timeout_task with the same negative ticks argument. As result, the
task is scheduled to execute not further than abs(ticks) ticks in
future, and the consequent enqueues are coalesced until the already
scheduled task is finished.

encryption types.
The AR5210 only has four WEP key slots, in contrast to what the
later MACs have (ie, the keycache.) So there's no way to store a "clear"
key.
Even if the driver is taught to not allocate CLR key entries for
the AR5210, the hardware will actually attempt to decode the encrypted
frames with the (likely all 0!) WEP keys.
So for now, disable the hardware encryption entirely and just so it
all in software. That allows both WEP -and- WPA to actually work.
If someone wishes to try and make hardware WEP _but_ software WPA work,
they'll have to create a HAL capability to enable/disable hardware
encryption based on the current STA/Hostap mode. However, making
multi-vap work with one WEP and one WPA VAP will require hardware
encryption to be disabled anyway.
